I'm restoring a 74 Yamaha DT100 and have had in the past both a Suzuki TS185 and Yamaha DT175, both obviously with the injection system. Never had a problem. The biggest advantage, as was in my case, was the different riding I did. I.E. trail and street, wide open and puttering. If you pre-mix the oil for wide open, and you putter around, you'll foul out. On the converse, you mix for puttering and the occasion comes to run out higher rpm's you chance leaning out. I think the oil injection solves this. Best point you make is preparing the bike for long stints without riding. Gas stabilizer and bleed the oil pump. Thanks, great video.
Thank you very much for the video. I’m about to purchase an aeroplane with a oil injected two-stroke engine. And I will have to make sure that we keep making sure that the oil injector is cared for then.
I haven't read the comments - however, the oil pump does indeed lubricate the crank bearings. There are many reasons why you should NOT remove said pump - for instance - premix is a "set" amount of oil. Pumps REGULATE How much OIL is sent to the engine... if you run slow - and you have a pump, then, you don't need LOTS of oil being mixed, there fore the bike will not "Load up" or possibly foul a plug. If you run the bike HARD - lots of oil will be sent to keep things proper. Taking the oil pump off... will stop all the regulation, and cause the crank bearings to not be lubed properly... Unless you like rebuilding engines - keep the pump in it and check the cables and the functionality of said pump. The gear behind it is what wears out - when that happens, the pump fails... so... proper maintenance yields a fine running machine. Too rich or too lean with cable adjustments needs to be addressed. I have two bikes with oil injection both are from the early 1970's. All my friends say "Lose that dead weight, and get rid of the oil injection" I just smile... fill the tank with INJECTION LUBE (not thick 2 stroke oil) and add 91+ Ethanol Free gas to the tank, and i'm off and running... 927 bean oil is too thick. Do your homework for Injection oil - purchase the PROPER oil, and run ETHANOL FREE gas and maintain your bike... What oil do I use? Amsoil designed for Auto Injection... Its not cheap - a tank lasts quite a while.
Nice Video, I've had many different injected 2 strokes for well over 30 years. Today I'm having my first problem with the pump. They are very reliable. The bike has to sit for a lot longer than a winter for it to gum up.. unless you have the wrong oil in it..
Your right about alot of things but I have been told a couple times that the 2 stroke oil you put in the oil injector reservoir is NOT the same as regular pre-mix 2 stroke oil. I used to have to buy a specific kind for the machines I had.
Dude, this is an antique design that's been upgraded to fits its counterpart. There a shaft with a screw gear on it, the crankshaft makes it turn in the crank case and it spins the pump. Think about it, 100 years ago, this was cutting edge technology and guess what? It's simple, it works and it is tough to break one of them - it's a 100% mechanical pump. It is a smarter design than diaphragm fuel pumps.
Polaris is also using this type delivery and yes they can be a pain if not familiar w/the internal working of the 2 cycle engines Just a matter of checking them periodically and that makes a big difference
If it fails then your engine blows up and it's more stuff that could potentially break. I wouldn't say it's the worst mechanical mechanism to exist but definitely not better then the pre mix way.
I would have to respectfully disagree. The oil pump is the best invention. They are very reliable delivering the precise amount of oil ensuring a long lasting engine. I have never seen one clog up with clean oil.
Thank You! You just solved my problem of fabricating my own. This will be perfect for making my 2 stroke run on propane. A method for controlled oil delivery to the engine has been a problem I've yet to achieve with any high degree of efficiency. My next option to explore was going to be using a Pi or Arduino controlled valve and/or pump for oil injection. This just simplified the whole thing. Thanks my Canadian friend!
so a public service announcement, a 1970's era Suzuki ts185 NEEDS to run on the oil injection pump. as he said, one of those lines run into the bottom of the block, where it properly lubricates the crank bearings. premix will NOT give it enough oil and you'll burn up your engine.
yup have the same bike.. you NEED the pump! very smart design, good lubrication and no two stroke smoke! just check the pump periodically by changing oil colors to make sure its working.
Good advice on the color! I wish we could get a forum or subReddit for 70's TS185s (and i guess 125s), as it's hard to find info and i'd love to chat with some others who've got them or know about them.
Very useful video and it explained a lot. My sled just seized up on me tonight and I'm thinking that the pump was the culprit. Is there a way to test these pumps? There is 2 lines going to the carbs,, one you could visibly see oil in the line, on the other line, you could see that there was no oil in that one. You think bad pump or just clogged n needs to be cleaned?
It would be great if it had a simple flow rate solenoid that set off an audible alarm if it fails to flow...but unless you're checking you exhaust when you go to gun it, you might get some unwanted engine block ventilation! Nice vid, I always add the same mix to the tank in case it cuts out, with 2oz of SeaFoam per gallon to make sure extra oil doesn't sludge or foul or score the pistons and crud up, it's a nice failsafe and hardly noticeable, but in case it fails I'm not getting towed back in! SeaFoam at this point shouldn't really be just an option at this point with ethanol and such anyways!
Yeah it would work, but what i would do is remove the fittings from the engine and just put short bolts into the holes instead with nylon washers, so theres no air leaks. if not u can do what i do, put oil in the injector and run the engine on 50:1 mix so that if the injector fails u still have oil in the gas that will keep the engine alive in such an event.
I just got a new engine DR Evolution 50cc air cooled for my scooter and replaced everything in the transmission. The connecting rod bearing somehow fell apart and made it into the chamber destroying the engine. This is a Peugeot Speedfight II and it was the original engine with about 15.000kilometers, I've been told it was just too old and that's why that happened not because it didn't get enough or any oil cause apparently the autolube works or at least its consuming oil from the oil tank and there is no oil leakage sign anywhere so it must go into the engine I guess. I've been told that through the break in period which is 500km which I've been through already, add an extra 10-20ml oil to the fuel tank. I actually added 40ml and recently after 400km 60ml because I was trying out the limits of the new engine. My question is, would it harm the scooter if I keep adding extra oil to the fuel? What would be the limitations for that? I know the 50:1 ratio, I have a 7l fuel tank so if I were to premix oil with fuel I should add 120ml which I guess would be too much oil of course and the mixture would be too lean making the engine hotter and thus causing an engine seize no matter the extra oil. But like would 60-80ml extra oil do any damage or would it even do any good in the first place or its not even necessary at all to add even a small amount of extra oil to the fuel if the oil pump works in theory? I'd be glad if someone could help cause I'm more of a car guy, I just got this scooter to have some fun with it at places where my car can't go, I know how the 2t engine works and the premix would be also simple solution I know. I'm not really familiar with the autolube system but I guess the engineers designing these scooters and whoever came up with this autolube system must know what they are doing and how this system is supposed to work. So I wouldn't wanna just go with the "disconnect the autolube and mix it on your own" what most people say on forums.
I am a bit paranoid about the failure of m oil injection system. I recently purchased a ts185er and it has the same system installed. So remarkably similar with the image its not funny. I was doing some research that is leading me away from the path of running premix. The previous owner ran premix for a while and it seemed to survive however there seems to be thought from experienced techs saying not to do it as the bearing on the left side is lubricated directly by the oil injection pump via a gallery and disabling it will not allow adequate oil toe lube that bearing and consequently premature failure. Though running premix ensures your wont kill an engine from pump failure ironically running premix and disabling this may also be bad. I understand it is due to the design of the crankcase, clearance from the crank to bearing and the fact that there are no holes in the bearing to the crankcase to allow premixed oil to enter easily and lubricate it properly.
Thank you for a brief explanation and how does the used or previously injected oil return to its tank? or how the scavenging of used oil takes place? thank you.
I have that exact same pump on my Vespa. I previously thought that that second line was for returning oil to the tank, due to a relief valve, until you explained to us that it was for lubricating the bottom end. The pump is a good idea, only if it functions without fail, because you don't have to worry about the fuel in your tank dividing back into gasoline and oil, after longer periods of not driving the vehicle. My question is: Does that cable operated valve only regulate oil flowing into the carburetor or does it also affect the oiling of the bottom end? The reason why I ask is because if the bottom end is continually fed oil, then it's possible to use the engine for braking which is a good way to destroy a 2-cycle engine, when the oil is mixed into the fuel. I have a hose connected to the manifold, assuming that it sucks oil in, when the engine is used for braking
Great break down, Thanks. Heres a question if anyone can help.. I have 2008 yamaha dt 125. the reserivour oil tank is full but the cylinder is dry when I unscrewed the cap to check inside. im not sure if its bad or not but I added some oil directly into the cylinder. I would like to get the bike running (even if I dont take it out for a ride), since its been sitting for two weeks now. Q: is it bad that I added the oil to the cylinder? Q: Should I try to start it up in a few? Q: could it be anything else other than this piece?...iv already massaged and moved the lines around in case they were gunked up. Q: is it safe to remove the hose to check that there is no blockage?..im concerned about air pressure.. Please advise, thank you.
Thanks for the great explanation, should we take it apart for cleaning each year? Mine is on a 1975 Suzuki GT380, which seems to partial seize after it warms up, it automatically stalls out at that poing, after rocking the bike in gear it frees again. Any ideas?
possibly might need to bleed all the lines of air, make sure they are not cracked and hard. test using premix, pull a carb feed line and see if oil burbles out, but stalling can happen for many reasons
pds tech thanks for the tips.It was starting and running fine, then recently after start up and warm, it stalls out suddenly at the same time locking up the kickstart which I presume is due to one piston partial seized, after rocking it in gear it free's the piston/kickstart again. On this particular bike the oil pump also serves the crank, it means premix would not oil the crank? Thanks again. Jeff.
premix would still reach the crank and rod, but in less quantity than the oil feed line gives. piston seize is fairly serious and there may be some damage to one cylinder. not the easiest bike to work on! triples are great! but kinda hairy to deal with. unless you've been all through the buke before, and it's a classic so you should have a mechanic pull the heads for a peek and go thru the injecttor pump. read up on this if youd like to tackle the job yourself or know what you might get in to: www.pinkpossum.com/GT750/Oilpump.htm
pds tech Thanks again, when I got the bike it was not running and in not so good shape. I spent money and put a lot of time to make it sweet again. When I first got it the center piston was stuck, at the shop they managed to release it and got the bike running. Some time after that I removed the head to check the piston rings, all was okay, Since that time it has had probably at least 1000 miles added (but low mileage anyway,) The only other thing I had to do was to replace a seal on the gearshaft, the old one was dried and leaking. That was successful. On a fine day I will try your suggestions. Thanks again, Jeff.
On my Aprilia RS 125 yes, oil "clugged". I have cleaned it but it does not seem to give any oil (only testing using the starter engine and certainly no spark plug. It has been oiled). Do I have to buy a new pump?
I have a 74 TC185 I’m fiddling with now. No oil flow at all from pump even with prime.... Unfortunately these motors have to have the oil pump as one line directly feeds the crank bearings.
I have a 2 stroke 49cc scooter. I have a leak, but the baffling part is that it appears both the gas and oil tanks have mixed somehow! Is it possible that the oil and gas are backflowing into one another somehow because the leak? It's a really weird problem. Is it more likely a crack in the divider between the gas and oil tanks? I just have no idea. My bike only has 138 miles on it! It's brand new! I'm thinking about fixing the leak, and siphoning everything out. So far the bike runs fine but I'm afraid of blowing my engine. Any ideas?
Hey mate, Ive got an 83 ts 185 er that started when I bought it, got it home and it wouldn't start, cleaned the carbi meticulously, it has good strong spark, good compression, no air leaks but just wont start unless I put some petrol either in the cylinder or in the back of the carb where the air box attaches. It will run but only until the fuel runs out. float all works and bowl fills fine, pilot jet clear.. I'm going mad?? Any clues? Cheers
I have a 2 stroke 1974 suzuki ts185. Can I bypass this oil injector and just mix my oil and gas without missing any necessary lubrication that this pump would get to and the oil gas mix wouldn't.??? I'm very new at motor bikes. Thanks utubers
Hello everyone I have a Suzuki TS 185 from 1982 it drips oil from the oil pump. and there is too much oil in the gasoline so the spark plug gets soaked and will not start. Is there a way I can fix it? Great video
Thank you for making this video! I was just sitting there holding the exact same oil injector ans was scratching my head. Just traded for a '75 tc185 and I do not have much mechanical experience. THe bike had been running on premix, and I decided to reinstall the oil pump because i read that certain parts would not recieve lube without it. Any tips on how I can bleed the pump to make sure it's functional?
So you keep your oil reservoir full of oil, leave the injector in place, and mix oil into your gas as well? I have a feeling my oil injector is failing and want to try this. What problems will be caused if there is too much oil being delivered to the cylinder?
I'm 15 and have a 1972 TC 125 Suzuki I was given, it obviously hasn't been run in years and the oil pump is not functioning. However the engine runs great and the bottom end is good. Anyone know how to fix the oil pump?
I have a scooter with one of these and I don't really trust it. So if I premix the gas/oil and put it in the tank that won't gunk up and engine/carb that was designed to be used with an oil pump? And would I just leave the oil pump on there but not fill up the reservoir?
Soooo your saying that the oil pump that is great for people who don't want to premix is the dumbest invention ever because people are to lazy to winterize correctly? im pretty sure that's not the inventors fault. By the way even the brand new snowmobiles have oil inject pumps and they work great.
@pimpinpenz cool ive been subbed to you for a while. i put all those into one video. im gonna add annotations now. can you make a video of how to split the transmission? i have to replace the oil seal between the engine and trans.
Hi i've TS90 with an identical pump, is there anyway of adjusting down the delivery as mine smokes like a chimney. if not what the fuel petrol mixture ratio i should use? (20:125:1 etc). Thanks in advance Gez England UK
it could be that you have a wrong pump, look at the number on the "butterfly" lever, the oil debit can be to much for yours, as a 185 has a bigger need. Those pumps look al the same but aren't. Number is key
If I just remove the oil tank and plug the hose going to that pump, and premix...will that pump not doing anything hurt the bikes actual engine? I'm stuck and really need some help. Thanks.
If the oiler oils a bearing in the crank case then you'll need to hook up a squeeze bottle and oil it manually or after 100 miles you'll be ordering parts blown up
+Eclidean There are many top name TCW3 oils that are "universal" now for use in premix or oil injection systems. Air cooled or water cooled. Yes, I know "TCW3" is a water cooled oil designator, but the oils are becoming universal now.
Eclidean Almost all conventional and semi synthetic 2C oils are madefor both premix and injection uses. Full synthetic 2C oils are for recomended for injection only.
Well the reason they plug up is because stupid idiots neglect there machine and don't keep up with it and then wonder why there engine blows there's no one else to blame but themselves.
ye i get it, but it is better to just connect it to the cranckshaft case to work like a regular oil system in any engine, so i do not get it why do they do it like this.
Pre mix works.if theres a bearing that gets oiled from the oiler when you do the delete you get a squeeze bottle and plug it onto that bearing line and give it a squeeze each use
A good quality oil won't go off over winter storage. It's not like 4 stroke engine oil that gets contaminated with combustion gases, which if condensation gets in 'water' can lead to the formation of sulfuric acid and eat at crank journals , eat at the crank. Additives in engine oil will evaporate off over time if not sealed, but you fill the oil resovoir on your scooter, and seal it off with a cap. Oil sits in a sealed jug when you buy it, or a sealed oil resovoir on your scooter. It's still sealed. Lastly, any quality 2 stroke oil with have cleansing detergents in the additive package.
@outdoorsman310 i dont have a bike i can split the transmission on right now. I seen that video and what you have to do is remove your cluch cover and change the seal thats in there. Its not too hard
I have a snowmobile that the previous owner ran on premix instead trusting the injector ,does the pump get ruined without oil through pump? Does any one know
If wanting to run oiler again if fill oil tank and mark it and premix gas ride a few times make sure oil tank is going down thatd be the lazy way to do it.
Yes oil injection has its down side, only works for people who know how to maintanence these . pre -mix is for people who don't understand and just want to ride. all my oil injections work fine and have for years. I guess the manufacturing corporations spent billions of dollars on research and may know a thing or two about the performance gains from oil injection.. But hay for you that just want to ride mixing your gas is fine...
@outdoorsman310 haha, Man those kawasakis only have 1 tube going to the intake. And idn why it would have lime green stuff in it? Was it pure kawasaki BLOOD? :p

The ts185s run forever. Mostly because of possibly the BEST "mechanical mechanism ever made".
What oil do you run? I was using suzuki CCI oil but now that is discontinued and I've restored my bike.

You can premix safely still you get a squeeze bottle to oil the PTO bearing or crank bearings and give it squeeze before each use just like a sled
Ha I love reading posts about people deleting their oil injectors thinking their premix cheat will lube their bottom end.

DO Not Disconnect the oil injecton on Suzuki singles under 400ccs
For how many gas fills do you add oil to the oil compartment for the injector?
I have never once had a problem in over 20 years with a oil injector on any 2 stroke engine, Bombardier, polaris and Kawasaki brands specifcally

thanks for the tips.It was starting and running fine, then recently after start up and warm, it stalls out suddenly at the same time locking up the kickstart which I presume is due to one piston partial seized, after rocking it in gear it free's the piston/kickstart again. On this particular bike the oil pump also serves the crank, it means premix would not oil the crank? Thanks again. Jeff.
premix would still reach the crank and rod, but in less quantity than the oil feed line gives. piston seize is fairly serious and there may be some damage to one cylinder. not the easiest bike to work on! triples are great! but kinda hairy to deal with.
unless you've been all through the buke before, and it's a classic so you should have a mechanic pull the heads for a peek and go thru the injecttor pump.

Thanks again, when I got the bike it was not running and in not so good shape. I spent money and put a lot of time to make it sweet again. When I first got it the center piston was stuck, at the shop they managed to release it and got the bike running. Some time after that I removed the head to check the piston rings, all was okay, Since that time it has had probably at least 1000 miles added (but low mileage anyway,) The only other thing I had to do was to replace a seal on the gearshaft, the old one was dried and leaking. That was successful. On a fine day I will try your suggestions. Thanks again, Jeff.
Thank you soo much man i couldnt figure it out
On my Aprilia RS 125 yes, oil "clugged". I have cleaned it but it does not seem to give any oil (only testing using the starter engine and certainly no spark plug. It has been oiled). Do I have to buy a new pump?
I have a 74 TC185 I’m fiddling with now. No oil flow at all from pump even with prime.... Unfortunately these motors have to have the oil pump as one line directly feeds the crank bearings.
I have a 2 stroke 49cc scooter. I have a leak, but the baffling part is that it appears both the gas and oil tanks have mixed somehow! Is it possible that the oil and gas are backflowing into one another somehow because the leak? It's a really weird problem. Is it more likely a crack in the divider between the gas and oil tanks? I just have no idea. My bike only has 138 miles on it! It's brand new!
I'm thinking about fixing the leak, and siphoning everything out. So far the bike runs fine but I'm afraid of blowing my engine.
Any ideas?
Hey mate, Ive got an 83 ts 185 er that started when I bought it, got it home and it wouldn't start, cleaned the carbi meticulously, it has good strong spark, good compression, no air leaks but just wont start unless I put some petrol either in the cylinder or in the back of the carb where the air box attaches. It will run but only until the fuel runs out. float all works and bowl fills fine, pilot jet clear.. I'm going mad?? Any clues?
Cheers
Man, that would drive me insane....
I have a 2 stroke 1974 suzuki ts185. Can I bypass this oil injector and just mix my oil and gas without missing any necessary lubrication that this pump would get to and the oil gas mix wouldn't.??? I'm very new at motor bikes. Thanks utubers
I had one of them, i also have a ts250. Both i ran premix in.
Walt Junior?
Hello everyone
I have a Suzuki TS 185 from 1982
it drips oil from the oil pump. and there is too much oil in the gasoline so the spark plug gets soaked and will not start.
Is there a way I can fix it?
Great video
Cool explanation, cheers!
Thank you for making this video! I was just sitting there holding the exact same oil injector ans was scratching my head. Just traded for a '75 tc185 and I do not have much mechanical experience. THe bike had been running on premix, and I decided to reinstall the oil pump because i read that certain parts would not recieve lube without it. Any tips on how I can bleed the pump to make sure it's functional?
So you keep your oil reservoir full of oil, leave the injector in place, and mix oil into your gas as well? I have a feeling my oil injector is failing and want to try this. What problems will be caused if there is too much oil being delivered to the cylinder?
Carbon deposits, too much smoke, that's about it, maybe a fouled plug if u don't open the loud pedal or grips enough.
I'm 15 and have a 1972 TC 125 Suzuki I was given, it obviously hasn't been run in years and the oil pump is not functioning. However the engine runs great and the bottom end is good. Anyone know how to fix the oil pump?
I have a scooter with one of these and I don't really trust it. So if I premix the gas/oil and put it in the tank that won't gunk up and engine/carb that was designed to be used with an oil pump? And would I just leave the oil pump on there but not fill up the reservoir?
maybe there is better fuel atomization when there isn't oil in it!
I knew someone who had one of these on his jetski boat and his oil line clogged and it seized the engine and left him stranded in the water.
WELL DONE, BUDDY.
@pimpinpenz i thought you had to take the crankshaft out. its the seal on the crank. the clutch cover gasket is new
Soooo your saying that the oil pump that is great for people who don't want to premix is the dumbest invention ever because people are to lazy to winterize correctly? im pretty sure that's not the inventors fault. By the way even the brand new snowmobiles have oil inject pumps and they work great.
Cuban Gamer you can say the same for people who are too lazy to premix
Is there a way to make a pre-mix 2-stroke use normal engine oil?
Even if that involves modifications besides just bolting something on
Anthony Williams No
Lol some of these questions are great
Any idea how much psi this pump makes? I want to add a pressure switch to mine so I don't seize another engine. Thanks.
.maybe 5
@pimpinpenz cool ive been subbed to you for a while. i put all those into one video. im gonna add annotations now. can you make a video of how to split the transmission? i have to replace the oil seal between the engine and trans.
Hi i've TS90 with an identical pump, is there anyway of adjusting down the delivery as mine smokes like a chimney. if not what the fuel petrol mixture ratio i should use? (20:1 25:1 etc). Thanks in advance Gez England UK
it could be that you have a wrong pump, look at the number on the "butterfly" lever, the oil debit can be to much for yours, as a 185 has a bigger need. Those pumps look al the same but aren't. Number is key
hello there i have a suzuki 750 gt 1975 did u recomend me to keep the oil pump or just eliminate the system?
Supposedly the only thing that can go horribly wrong on a 2 stroke engine is this thing
So how do you fix the lines?????? The check valve can't be taken apart....
@BriggsMower thats what im doing now because one of the bolts on the injector is broken
Im sure now if they used these for modern 2 stroke bikes they would redesign them and they would be good.
They are designed just fine some people will find anything to bitch and moan about
Because people forget that you need to bleed them if the tank has been run dry
Lol if the tanks been run dry ya might have more issues than that
How do you winterize a 2 stroke bike with an oil injector then?
thiner oil ma boy
You never stop the engine. Just add oil and gasoline regularly and change the color of the oil. Never failed with me.
Fine explaination Scooter!! Many a 2 stroke met it's premature demise because of those Lil suckers eh!!☺
Kia yh oil pump suzuki B 120 japani 1976 ka ml skta hy kahan sy
@outdoorsman310 when i did that to my old rt100 it gave it more power and better fuel economy
Never ever had a problem with oil
With oil injection never had a
If I just remove the oil tank and plug the hose going to that pump, and premix...will that pump not doing anything hurt the bikes actual engine? I'm stuck and really need some help. Thanks.
If the oiler oils a bearing in the crank case then you'll need to hook up a squeeze bottle and oil it manually or after 100 miles you'll be ordering parts blown up
@BriggsMower usually the best thing to do.
do i need this can i just mix it my self
Pre-mix oil and injection oil are different and NOT interchangeable
+Eclidean
There are many top name TCW3 oils that are "universal" now for use in premix or oil injection systems. Air cooled or water cooled. Yes, I know "TCW3" is a water cooled oil designator, but the oils are becoming universal now.
Eclidean
Almost all conventional and semi synthetic 2C oils are madefor both premix and injection uses. Full synthetic 2C oils are for recomended for injection only.
@pimpinpenz when i took the cylinder off there is a hole in the crankcase im guessing thats for injection? but im running premix anyway so i dont care
Ooohhh.... I ride during the winter !!! I ride the hell out of winter suM
i had a old bike had one i drained the oil tank and the just ran the bike off a premix in the main tank it ran fine for 3 to 4 years with out a issue
How do I properly adjust my on 75 ts185
Well the reason they plug up is because stupid idiots neglect there machine and don't keep up with it and then wonder why there engine blows there's no one else to blame but themselves.
Thanks buddy that was usefull.
ye i get it, but it is better to just connect it to the cranckshaft case to work like a regular oil system in any engine, so i do not get it why do they do it like this.
The last time I bypassed a oil injection I just ran the line back into the oil tank, and plugged the inlet to the intake. And just mix the gas
can you replace the tubes on those things?
If you can find them.. I can’t
and some lime green stuff in it
A lot of the two-cycle engines inject the oil directly in to the crankshaft bearings. Pre-mix will not work!!!!!
Pre mix works.if theres a bearing that gets oiled from the oiler when you do the delete you get a squeeze bottle and plug it onto that bearing line and give it a squeeze each use
Stale oil? I didn't think it went off?
A good quality oil won't go off over winter storage. It's not like 4 stroke engine oil that gets contaminated with combustion gases, which if condensation gets in 'water' can lead to the formation of sulfuric acid and eat at crank journals , eat at the crank.
Additives in engine oil will evaporate off over time if not sealed, but you fill the oil resovoir on your scooter, and seal it off with a cap. Oil sits in a sealed jug when you buy it, or a sealed oil resovoir on your scooter. It's still sealed.
Lastly, any quality 2 stroke oil with have cleansing detergents in the additive package.
to keep mine form stopping up i use seafoam
mine had only one tube to the intake
How do you adjust them more oil less oil
Go over the mark or before the mark
@outdoorsman310 i dont have a bike i can split the transmission on right now. I seen that video and what you have to do is remove your cluch cover and change the seal thats in there. Its not too hard
I have a snowmobile that the previous owner ran on premix instead trusting the injector ,does the pump get ruined without oil through pump? Does any one know
What kinda sled I'd make sure it didnt need the oiler to oil the PTO bearing..
If wanting to run oiler again if fill oil tank and mark it and premix gas ride a few times make sure oil tank is going down thatd be the lazy way to do it.
A snow mobile is best off keeping up on spark plugs
whats the best way to unblock theese 2stroke pumps ?
Crack the bleeder and let gravity take over can crack the lines while running and burp it till you have straight oil no air
Yes oil injection has its down side, only works for people who know how to maintanence these . pre -mix is for people who don't understand and just want to ride. all my oil injections work fine and have for years. I guess the manufacturing corporations spent billions of dollars on research and may know a thing or two about the performance gains from oil injection.. But hay for you that just want to ride mixing your gas is fine...
Bikes with these pumps shouldnt run on just premix, premix will lubricate the top end but not the bottom.
+Patryk Not correct at all. Look into how a 2 stroke engine works.
Look at different TYPES of 2 stroke engine designs, not all necessarily have lubrication dedicated to the bearings..
QUESTION... why cant someone inject two stroke oil electronically through an injector?
@805ROADKING yes they have! oil injection sucks.
I foresee a lot of oil fouled plugs in your future...
I'm not seeing oil injection ports I'm seeing nitrous injection ports.....
g00d 2 know
Is this Woody Harrelson ?
@pimpinpenz now it has atf in it! lol
there scary devices, my vro system on my boat is about to go:/
@outdoorsman310 haha, Man those kawasakis only have 1 tube going to the intake. And idn why it would have lime green stuff in it? Was it pure kawasaki BLOOD? :p
I want to put on my trabant if you don't know what a trabant is google it is it even possible
@pimpinpenz okay ill try
@dc5000123 sold the bike a while ago.
what ? duhh all u need to know duhhh . maybe they oil the mains?
