it started first kick 😭🙏
T-bolt pretty much always includes throttle cables and clutch cables with their engines
I felt like they did to because I’ve ordered 7 years ago but in the receipt and before ordering it said it doesn’t include it but you can add it for more money. So not sure why it says that but either way made my day lol
I realise this is a bit late, but I'm about to put the 140 in my Sachs Madass, which had the electric start Lifan 120cc. I'm struggling with the wiring conversion. Did you make a video in regard to this? or have a schematic for the wiring?
I can’t wait to order mine 😢
👍🏼 beautiful 👍🏼
My yx 140 kicked back ripped drive of kickstart drive gear clutch basket and cracked inner engine case scrap not 3months old
Do you have more info about that, I was riding my swapped 140 today and still learning it but it leaked oil from the countershaft and can't find anything on the internet. Drained the oil the gears looked good when taking the covers off, and restarted it and it ran fine but at first before that the piston sounded like the vales were tinging or piston knock but that went away and it was like normal. I want to do a stator and clutch and replace the oil and can't find a countershaft seal or "front sprocket seal for this motor, any help appreciated
Need a video on float height settings and adjustments on the piranha 125cc mikuni carb please, having a hard time finding the correct info on the procedure and can’t think of anyone better to do one than you!
The carb is suppose to come factory with the correct float height? What issue are you having?
I’ll put that in my list of videos to make!
@@slavsquad just started yesterday idling kinda weird, I’ll idle fine for 10-15 seconds then it’ll drop down about 1500 rpms for a second or two then back to fine, didn’t do it at all the first week I had the motor
@@zealdistortion hmmm that’s interesting. Did you trying cleaning your carb? Clean the jets? The idea for the foot height is basically that it’s suppose to be level with the carb. Kinda hard to explain. Not certain that the float would do what Ls happening to you tho. Could be wrong
@@slavsquad yeah I think a good cleaning of the carb is my after work project today
@@zealdistortion yeah start there and see if that helps any
just bought one did the exact same thing😭🙏
I have a 140yx engine and it's extremely hard to start. It doesn't turn on without using the gas but when i use it the bike kicks back like a horse. Also when i rev it idles stay kinda high for sometime but then decrease so much that it sounds like the engine is shutting off.
your idel air screw isnt set right
Is there a bore kit available for the yx140?
Does it always come with the wiring harness
Yes it should always come with a harness
Why are you checking the valves for clearance and also putting it on time ? Aren’t they ready to go ??
No the valves are off from factory. You need to adjust them
Timing is suppose to be correct
@@slavsquad wow well that’s good to know lol I’m going to buy one soon and was planning on just throwing it on 🥲
@@geo_eatz4043 I’ve done that before lol but yeah its not fully ready to go
What size air filter do you put on the carb
Do you have any experience with the lifan 125 engine? I still have a stock chinese bike from when I was a kid, your videos made me consider riding it again. My plan is upgrading to a race cam and a vm24 carb. I hope that gets me some acceptable power because I am on a budget.
I’ve had one before but I haven’t done those mods
Hello. Very good video. Thank you for sharing. I just unboxed a new Piranha 140 semi auto with e start. I noticed weird head casting that seems to be purposely broken. I see the same piece on your motor at exactly 4:41 in your vid. The piece is just below the exhaust value to the right (looking at the motor from the front). At first I thought this was busted on shipping but close examination it is busted and painted over (likely from factory). Any idea why this is? Is this a concern? What about getting water up in there? Thank you sir.
I believe that’s just a vent area
Doesn’t go inside the engine
That is a factory designed cooling air scoop that grabs air when you are moving and directs it over and around the hottest places of the cylinder head. This duct is connected, so the cooling air exits out the other side around the spark plug if you look closely. Shine a flashlight or blow some compressed air in the air scoop and see what I mean.
@@doubleg1328 thanks for the reply. Makes sense now. Just really weird that the factory wouldn’t cast the part with the area already open. Or if it has to be casted and removed after the fact the factory could have uses a tool like a Dremel to cut it nicely. Instead they open it up with blunt force like with a hammer. Well I won’t worry about it anymore. I guess that’s what you get from a Chinese crate engine. Thanks again.
@Andrew Bibo Yes, they likely use a sand core in the mold when pouring the aluminum to create the void and knock out the sand after the aluminum has cooled and solidified. These sand cores are imperfect, so some heads have a thin flashing wall in that air duct that simply needs to be tapped to remove it. Expectations for a mass-produced China engine is all. However, they are quite durable engines that will serve you well.
Do you know if this motor will fit in the Coolster QG-214S-2 frame?
Not sure exactly what frame that is but it fits in most pit bike frames
I believe coolster has a similar design
Hi. Should I put lube to the chains in the engine or do I just leave them dry?
You don’t need to. Only important to lube bearings when you taking apart an engine.
If you have a new engine you don’t need to lube anything
so I installed this motor on my frame I started it up just to make sure the wiring worked. I totally forgot to check this stuff. I would assume since I didn't ride it or even if I did I could still go in and adjust this stuff?
Yeah you should be fine. You can go and check and adjust them. I’ve had a 125cc piranha and had no idea about this stuff. I just ran it as is but if you want optimal performance from your engine then make sure everything is in spec
That one was fine. I bought another one brand new and when I took off the covers oil came pouring out of the exhaust side…. Why..?
@@HeyItsAsmus probably not adjusted correctly?
I just got my piranha 125cc today can’t wait to put it on!!, I have a question, at 2:07 I noticed on your motor it has two metal sleeves on one bolt to run your carb hoses thru, mine only has one. Can I take that bolt out and add a second one without something coming loose inside the motor?
Hey James super excited for you! The 125 is an amazing engine. I have it in my CRF 50. As for your question you should not have any problems unscrewing that bolt and adding a second sleeve. Most of the time I don’t even use the sleeve anyway for those hoses. But if you want a cleaner look then you can add it
@@slavsquad awesome!!!, I really appreciate your reply and your vids, watched them numerous times in preparation for the arrival of the the motor
@@zealdistortion My pleasure! Thanks for watching and the support!
@@slavsquad well unfortunately startup didn’t go so well, won’t start and is pouring fuel outta the carb overflow
@@zealdistortion that’s no good. Keep trying it. Make sure fuel is connected and flowing well. Keep choke up, and make sure kill switch Is not on the off side.
If the fuel is pouring it shut off the fuel and lean the bike over to dump most of the fuel out of the carb. Also clean up your spark plug so it’s not wet. Then try starting it again.
Maybe before all that check for spark to make sure it’s actually getting spark
Do the yx 140cc motors come with the z40 racing cams from factory?
Good question. Unfortunately I don’t know 🤷🏻♂️
@@slavsquad I think they do I seen other videos mentioning that they put those in all the yx 140cc motors, I just wanted to verify
@@VDM32 it sounds right. I remember something about it but I can’t say for sure
Would the valve adjustment help with kickback?
Usually if valves are adjusted good and you have good compression you'll have pretty strong kick back on kick starter. you just have to kick it over when its at TDC so it doesn't kick back

man sorry for disturbing you... i have an ycf pilot f150 2016... in the manual says 600 ml and when i ask a man from ycf page for answers said to me 900 ml... can you help me please? idk what oil quantity to pour and i driving me crazy... i think it s the same engine... what do you think?
Does your engine have a dipstick or a way to know when the oil is full? I usually run around probably 800 ml of oil in most of the engines. I mainly use the dipstick to know when it’s full. 600 seems a bit low to me. Maybe run around 750? If Manual says 600 then technically it should be correct. This 140 took around 800ml I’d say. That’s measuring with the dipstick.
@@slavsquad , i have a dipstick and with the dipstick all in with 600 ml is ok. but when i just put the dipstick there not screwed all in is on the minim... also with 900 ml with dipstick lay there is almost max but with dipstick all in like screwed is overfill... one said that i should check the level with dipstick all in another man said with dipstick just putted there not screwed... idk what to belive...
@@boghez1519 I always screw the dipstick in all the way and I put it to max. Maybe even a bit over fill. I’ve done it for the last 10+ years. Go Galway between 600-900ml and you’ll be safe
Thank you very much man! I think i will go like 750 ml or 800 😁 i think is not too much even if the correct ammount is 600 :)
@@boghez1519 My pleasure! And yeah that should be perfect
Hello
Can u put this in any frame or has it gotta be a certain frame?
You can always fabricate but for direct bolt on it has to be a crf50 style frame
I believe klx 110 is the same and most groms
@@slavsquad yeaah I've got a crf50 frame ,so it will fit no matter what ,say got a m2r frame kxf version 🤣😬but it's crf50 lol so would I reckon it would ,and love ur vids mate 👌
@@bozzzah2978 it should! One way to find out for sure lol
Thank you!
@@slavsquad yeah tbh tho mate that's why I asked before buying one ,didn't wanna buy one then it not fit ,then be stuck uno ,but yeah irl have ago mate cheers for the advice look forward to your next vid
@@bozzzah2978 let me know how it fits!
What would cause this engine to "tick tick" even after every attempt to shut it up it still goes tick tick...kind of irritating.
Start with valve adjustment.
@@slavsquad I've literally tried everything short of completely disassembling the engine, valves are the first thing that gets checked out of the box.
@@gasdonkeykustoms6840 that’s weird. Is it a loud tick? I’ll run mine and see if it does the same. I know some do tick slightly and it’s normal
@@slavsquad check this out...lmao it was a pinhole exhaust leak in conjunction with too much restriction at the muffler. Had an 8yo tell me a few hours ago ,"it might run better if you take that stupid muffler off dude" so I cut the muffler off and it shut up and I spilled it not realizing I hadn't ran it at it's full potential since getting it. Funniest part is, he also said to check my valve clearance "HOT" said that's how his dad does it. I was having some top end issues as well. 🤯🤫 the bike in context is the one in my profile picture on here. Built from junk I acquired.
@@gasdonkeykustoms6840 dang that’s a smart 8yo haha I’ve never checked them hot before. Never crossed my mind.
Glad you got it figured out tho lol
I want one but 1600 is a little steep. Zr140
True that’s quite a bit.
Mine is not a zr140 tho. Mines the older Pitster Pro X2 rolling Chasis with the piranha 140 engine.
Find a cheap rolling Chasis for like 400-500$ and buy a new piranha 140 and your good lol
i thought it was 800ml
Based off TBolt where I bought the engine they say approximately 900ml of 10W40. And based off my experience that’s about right. I put almost a full quart.
@@slavsquad i put half and it shows full on my dipstick ill probably add more then change it after like 2 hours
@@3dwezzy740 I’d add more if I was you. More won’t hurt. You have the same engine right? If engine is different then it could use less
@@slavsquad yeah but semi automatic
@@slavsquad think it would hold a quart
Bro you put car oil in it. Thats no good need 10w40 non synthetic
where did you see me use car oil? I only run 10w40 4 stroke motorcycle oil. I looked but only saw at 8:22 where I poured oil and you can clearly see it’s a motorcycle oil. Just can’t see the weight of the oil. Definitely not a good idea to use car oil as it doesn’t meet the specs for the clutch and all the other little additives that motorcycles require
@travis davenport Synthetic oil is the best not traditional
