TH-cam has turned into complete s*** lately, this is one of the only channels that is still worth watching.
amen captain hover keeps us served up
lol he said retarted thats hate speach Lets get Him lol jk
@@Spacecruizer203 I wouldn't be surprised if he eventually gets demonetized or something because of the word. lol. even though it's clearly not hate speech but a different definition.
@@breezetix lol
I'm glad that the supervisor was there to oversee your work
What was the top speed you hit so far? I have my 85 on its way and was just wondering.i plan on leaving this engine all stock might cut a hole in air filter but that's Abt it
Lol
I raised the clip one notch on my moped's carburetor and the performance was immensely improved
Glad to see you alive and kicking. Thanks for the ride.
Best hack I've ever seen for these. THANK YOU !!!!!
I was going to buy ...stuff...to change timing. Not now 😊😊😊😊😊😊😊😊😊😊😊
Thanks man, this helped relieve my stress. The first part with the magnet, took it out to check my seal # and flipped it on installation.
Very informative video thank you and I'm looking forwarded to the future build.
yaaay been waiting for your new vid to come out! Love it! - Bikecuh
Thank you for another great video and basically answering my questions. About the clip on the needle seat. Thank you again
Glad it was helpful!
Your a God at tuning these things and that gas bike frame with this motor will be awesome
nice vid as usual. i found a good amount of play in my yd100 without filing the key at all. kinda nice to be able to play with it actually. peace!
I have that same frame and it works so well I recently hit 45 mph on it.
Nice video, just got my Seeutek out of break in! Thanks for the tips aswell
Yes sir 🚲💨💨💨 these bikes like to run at high speed and sound wonderful 💨💨 and good info the timing 💨🙏💯
Cool good info you passed along. And yes.. we were all wanting to see this wide open down the road. But, I get it. guess we will have to be patient for the update. I might consider getting this. The other motors in past I just felt was to china.. so never bought them. But, this is a great step in right direction.
Let’s go more phantom 85 vids!!
When you gonna upload again
@@keeganhache6667 whenever I figure out more original content lol
@@Everatti ok cool
I can’t wait to see the new bike frame
omg, i just got back from pushing/riding my motorised bike, it broke down!!! miles and miles i had to pedal it. must be the spark!!!! i kept thinking i must take a spark tool and spare cdi etc like la hover said!!
Very usefull video as always. If i replace the standard 6volts magneto coil with a 12volts magneto coil, it will damage the cdi?
Hi la hover I would like to thank you for the amount of information about Motorized bicycle.as it is my first china doll engine I bought off eBay is pretty nice I ride a bianchi mountain bike with a 80/66 cc and I want a next one maybe 100/85cc thanks again I’ve learn a lot of very useful information.i am 45 years at this time and enjoy crushing around on my bicycle ps I also own sports bike so speed is no problem when I need some bye from sunny Antigua and Barbuda wi
Interesting i might have to try this i would love a chill cruise speed
Hey I've been watching your videos for a while while going through the hoops of my own bike build. I had a cool idea about installing an electric bike wheel on the front of my motorized bike. Doesn't seem like anything could go wrong xD
i was thinking the same thing but i feel like if the wheels werent going the same speed there would be problems
@@sealdilly2691 I had the same thought recently. My thought though was using it to get up to speed. Electric to accelerate and fuel for the mileage. Could also use when hill climbing to help out the china girl. The different speeds shouldnt matter in those scenarios.
Thanks for the tutorial.My bikes been a bit off and moving the clip about hasn't done squat.I even went to a BR5HS for it's hotter spark as its ok in winter.It just wasn't right.I f'd up and thought 25:1,because of the 80-90F the last month would make the motor last longer,but now I see the DUH in that.Happy Trails.BTW.Even with the $140+ 'alloy wheel sets' you really have to check the bearings often.
I'm hoping I can convert my hubs from loose ball bearings to cartridge style bearings like what a motorcycle wheel uses....MTN bikers want the quick release wheels/axle but I think for a motorized bike, the beefier bolt on wheel axles are better. Pretty sure those quick release axles aren't nearly as strong and are for weight savings & making tire/wheel changes easier.
Ive had my crank seal leaking so badly that oil poured out of the stator cover as soon as I loosened the bolts, but engine still running! Those seals are tricky sometimes and each side is of a different thickness.
Hey, what's some good advice for building a phantom 85 for the first time? Not my first rodeo building a motorized bicycle, I got a BT80 powered hyper 7 speed cruiser on my porch, I've had a zeda triple 40, that one was a blast stock hitting 40+, a 49cc 4 stroke on a Kent Ridgeland, plus I have a Worksman trike that I'm put a 212 predator on.
I watched this clip just now for 2nd time just so I knew i was doing it rite and before I even jumped into it with sanding it down I just LOSEN nut and moved it back just to see results and it definitely made engine smoother And . listen this cat he's good with it guys enjoy and be safe 👍👍.now time to get the sanding!!
Yea it's crazy how much each engine varies I might even just leave it where I have it
Glad you are okay after the storm!
I was thinking about getting one of these, but I changed my mind. I can hit 42 with the Don Butler motor (just ported with high compression head and fake MZ, 44t) I've had it for about 2 weeks now. I am very happy. I have it on my Trek. You would like it. I had to take off the air filter and set the needle all the way down lean, with the bofeng. I'm going to eventually dig out my 21mm PWK . Have fun and be safe!
Thanks, and congrats on your build! sounds like a rocket, stay safe!
Wonder if you can get offset woodruff keys for these like you can get for cars? Might have a few more options.
I really like the phantom engine for it's lil size it has a lot of power definitely a sweet engine.i can't wait until someone comes out with a plug and play kit with a big bore jug.like a 54 ,56 mm piston
I did not know you could adjust the timing on these engines. Thanks
Great way to smooth out a motor without the fear of going to lean trying to tune out the carb.
Okay so I'm going back to this video and I need your information this video is on adjusting the timing on these phantoms I have my phantom in great shape it's running great it's just when I hit a cruise it starts 4 stroking
Theres a problem with my 49cc where it doesnt go idle and it instead stalls when i stop going fast
do you have to do something to the clutch to make it go idle?
I burned a hole on my piston messing with the ignition timing. Hard to find good pistons. Any recommendations.
Do u think the zeda 80 will put out more performance and go faster with an upgraded carburetor and a racing cylinder head
La hover my phantom 85cc make a really loud rattling noise when I full throttle and then I let off it makes a loud chattering noise. Can you help me? Don't know what it is
I'm putting an engine on a Schwinn Stingray with a Headstrom trike rear end. Both rear axles have traction via freewheel sprockets. This makes it so I have to pedal start the engine. I think I'm running a 25 to 16 crank to center shaft. And boy it still takes a ton of leg to start it. Sometimes it kicks over on the second try. Other times it takes a block to start.
I have a magnet that it's timing position is on the 12 o'clock position but cant find any information on youtube about it.
PLEASE DO A REVIEW ON THE BBR F ZERO
Does this engine work with a Schwinn Trailway Hybrid 700c/28'?
Hey hover love the vids. I got the fat belly pipe (mz65) clone and I was wondering how it compares to your wc80 pipe?
Right now I can't say, have not been riding enough to test them side by side yet sorry.
Somebody who knows way more than me said not to buy the mz65 clone and wait until I had the money to buy a real mz65 pipe. The real mz65 header part of the pipe gradually gets larger before it reaches the expansion chamber which makes a big difference VS the skinny header on the mz65 clone....He said the clone might give a slight power increase but is pretty much just a useless noise maker.
My bike does that but at high speed and full throttle, what should I do
Hiland Coolley is a great steel frame choice.
Can you please do a video on the "110"cc ebay motor kits?
Your on the right track but I would try fixing carb, spark etc and do timing last.
Biggest issue is exhaust at open throttle it doesn't creat back pressure as it should so will never be perfect.
Check engine squish with some plasticine in between piston and head.
Squish between .7 to .9 will work anything more and will need race fuel.
LA hover. One my piston rings snapped and all hell came to my engine so what happend is i replace my ring everything was normal until CERCK attop speed it died started it up fine 5 minutes later it tootally lost compression i check inside 2 mm craters on my piston and right below the intake port not as bad 0.5 mm can i run the block still?
Go check out my youtube video if you want to see the piston
How did you mount the gas tank on this Kent 7 speed 26 inch pos bike ? Took mine back cause I couldn't mount mine .
Recommended 11 gauge spokes
Pero cuanto levanta? Velocidad máxima? Buen video 👌
This might be the most useful gas bike video I've seen on youtube. But in my experience, 4 stroking can be tuned out w float height (mostly just full throttle, and even when properly jetted) More importantly needle profile (low to mid throttle).
@@joerolfe7967 Thank you for clearing that up. I had not realized that what sounds like 4 stroking, might not always be. As a hobbiest I experienced, as you call it ”starving”, with all the carbs I've used out of the box. And I hear too many bikes around my town that obviously have the same issue. So I am hopeful that my initial response may still be helpful to someone. 🍻
i would cut filing and work on my magneto i have a tuning thats maybe would work a german mechanic tolds me this ignition time is not late enough its to early but near at high performance i ask him a stock ones can be tuned with a magneto???? and he yes look at this and this i understand what he means but its not Neodym magnets crazy i do its not expensive replacement part
How would one tell if one needs to adjust the ignition timing?
Where did you get that intake manifold and exhaust?
I had a VW with a cylinder head guage, 350 was in the middle and 600 was over heated so your fine, I think my bug with a fan ran 280 most of the time
Thanks of all the info. Just got the phatom 85 delivered. What quality bike you recommend for that engine ?
I have no good recommendations for this motor at the moment sorry... Hopefully the new frame will be up to handling this motor. Will just have to wait and see.
@@LAHover Thanks for all the videos.
Yesterday I hopped on my bike with the phantom 85 to continue breaking it in and no power haven’t changed a thing from stock. Motor rips I just have no clue why mine doesn’t. Takes half throttle to barely get you moving on flat ground
Make sure yours did not come with a backwards piston. Guy I was helping the other day had one come backwards... Guess that is still a thing. May also be an issue with the reeds, one may not be sealing. Could be allot of other things too, hopefully just something simple.
I can verify it will break Walmart bicycles, most of the damage to the back tire spokes hub and axel bolt. Two tips to slow or even stop that from happening is don't use hub breaks or just no breaks on the back tire, and look into the upgrade hub mounted sprocket for the motor side of the bike.
You absolutely need brakes on the rear tyre. Slamming the front brakes on when you need to stop quickly never ends well!
I have my sprocket mounted on disc brake mounting points, works great
@@XxmatixX6videosdiariosdenadav thats sounds so nice . i spend almost a day fucking around with a ragjoin
You should check out CDH frames
Where is the best place to buy a phantom 85
I was wondering if you can give me some more information on that I've watched the video now like you said it's okay for someone who wants to just punch the gas all the time but there's times I want to just cruise it goes from two stroking to four stroking.
The adjustment I'm making in this video is for that exact situation. If needle adjustments are not enough to sooth out your cruising rpms, than a timing adjustment can often do the trick.
You should try to fabricate your own muffler, that would make for some hectic content
Just buy a cheap circuit pipe and hack and weld. Circuit pipe will give you the best take off and mid range with little increase in top end.
@@robertpolicastro1 True, that would really help the motor and would sound so good!
Speaking from experience (currently working on it) go over those BBR kits well. I just dropped the wheels off at a local bike shop. Not true & hubs no where close to centered. They're a solid start but not ready to go outta the box.
Thanks for sharing
Dude that gurgle or what ever sound, that is what mine does when i go above half throttle, and everytime it makes that sound, it would actually slow me down , then would come out of it, when i plyed with the throttle. im not sure what my problem, is, im still riding it like it is tho. lol Thanks for another good video man.
Hey bud I have a question for you if you don't mind answering. I bought a JRL half moon exhaust for my 100cc non branded motor, is it any good that you know of? The original exhaust that came with my engine got broken by me loosening the cap bolt to remove the cap and check the inside of it and to add loctite on the nut. So this is why I had to get a new exhaust and the JRL 40mm half moon exhaust was only 20 bucks so I went with it over the stock exhaust. Also I would like to add that I got a high performance 100cc motor kit that resembles the YD 100 and all the parts I have purchased and changed have been for the YD 100 and they fit to a T . I have a 50mm piston, 8mm studs, and a 1 piece top end with 40mm exhaust bolt on and intake. That's why I think it's a YD 100 unbranded, same specs. It also has a ton of torque and speed.
They work, but don't do much other than make the bike louder.
You might get a bit more power if it's less restrictive than the stock exhaust, but most are not tuned for these motors.
Would you recommend the phantom85 or yd100?. Im in the market for a new motor
(this opinion may change in the future) Out of those two options I would recommend the YD-100. We know the Phantom 85 is much stronger than the YD-100 that I can say for sure... We just don't know how well they will hold up yet. You also need to think about the bike it's going onto, The phantom's power needs a strong build IMO.
Will the phantom exhaust bolt on to a stock china girl motor if yes is it worth buying the exhaust for a stock china motor any gains of power low down on stock nt carb but high comp head would be nice to see a side by side stock with phantom exhaust and stock only high comp head phantom exhaust see the difference between them
No, the exhaust port and stud pattern is to wide.
How do you like the phamtom 85? Is it comparable the yd100?
Not comparable. The Phantom feels like it belongs on a pit bike, not a bicycle...
@@LAHover just bought the phantom 85. This will be my 11th build but I'm taking it serious thanks to your videos. I have the engine, steel mag wheels with sprocket and disc brakes. I just need the bike now. I don't have a price cap for my build. I just really like the process of putting a motorized bike together and riding on something I made. Your channel is a true gem. I appreciate you're content. Should I get a frame with the motor mount on it already?
@@LAHover I just seen ebay & amazon started selling a new 110cc engine kit....It's a 52mm piston with a 2 piece cylinder & head and the cylinder has an iron lined sleeve (supposedly iron sleeve)...ebay around $190 amazon around $210....I'm hoping I can sell my 66/80cc kit to my neighbor buddy and buy the 110cc kit....One problem I can see already with it is, if you have frame/engine/carburetor clearance issues. It'll be tricky to easily rig up an offset intake, with a true expansion pipe and a little port/polish. I'm hoping I could make a 40-45 mph cruiser bike.
You ever get around to the rebuild of roketa?
what jet are you using
Hey La where do I get 49 cc sticker for my engine
would it be feasible to put something in the gap in the woodruff key so that the magnet wont rotate out of timing?
According to one of my viewers yes. I have never tried it but he said it worked for him.
@@LAHover any idea what he used to fill the gap?
My experience with a bike kit like this is that there are scant quality parts that you can buy for them. I've yet to find a decent coil for mine that gives a strong spark and I've even tried switching the magneto too and I can't figure out which part is the problem if not both of them. The bike only worked for the first 2 months I used it. I just bought a new carb too as well as the coil and hopefully that will fix the problem of the bike not being able to run unless I'm going down hill or have built up lots of speed befire hitting a hill. You can't trust Amazon sellers or eBay either. There are so many garbage listing that it's near impossible to find anything decent. I've also learned that these bikes need constant maintenance in order to function. By constant I mean be prepared to clean and rebuild the carb every couple months and expect the coil to need replacing every couple months too. And expect to have to buy multiple substandard or non working replacement parts, also never expect that they will come with the correct sparkplug, ever as they won't. and dont think that buy8ng the more expensive ones will be better they aren't and will be the same as the cheap ones and same w8th the red so called Racing ones they are just red and not better at all. And because the wires all have spade terminals you will have to put new spade terminals back on the wires to get a refund. I've never seen wiring that uses them on the kits but the replacements all have them. And the laminations on the magneto are usually horrendous and are normally bent or loose. They are also made from the worst grade of steel ever and are thick. So don't expect a decent spark. It's a dice roll to get lucky and relieve good parts and are rare. Why this is the case is that there's obviously only one or two maker of these kits and the one that makes the crappy ones has 95% of the listings that exist. I'd be glad to pay 400 for a quality one but due to the 400 priced ones being the same ones as the 179 priced kits you are wasting your money spending the extra. If anyone knows of a quality source let me know.
Where can I buy this motor package?
I put my engine in a bike from a second hand sports center and it’s been more than good
Indeed help please contact me asap it about my phantom85 I think my timing is wrong the pull start messed it up
What's in the cup holder
Hover cheers ,i got my gas frame i will post soon im running my 100cc anbull no one has posted one it has a nice kick also .stay safe riders
Sounds great!
@@LAHover i owe alot to you and few others here .i can't wait for your bike to come hover
My engine has excessive 4 stroking but it'll run just fine so I'm almost sure this is my problem but this honestly intimidates me and I'm not sure why lol
I just got one of these engines, haven't even been able to look at it as I haven't been home... I would love to know how removing one of the gaskets affect things on this engine.
any gasket removed would make it not run so...
@@gewizz2 not true. Some engines come with 2 cylinder gaskets to increase headroom when not needed.
@@Hunter1st a gasket squeezed between the cylinder will change nothing in performance.
@@gewizz2 it actually can greatly. I don't know where you've gotten this information.
@@Hunter1st ok, i have not experimented with stacking gaskets up, they way i see it, more gaskets means more potential for leaks. but anyway if you raise the whole cylinder 1 mm, it changes everything, so where is the benefit? more compression above means less in the crankcase, ports opening earlier mean ports closing earlier, its hardly beneficial. anyway my 66cc engine is not running i had to pedal it 11 miles!
Hey there fellow motorized bike enthusiasts. Just racking my brain over this little over half throttle the engine just almost completely falls on its face. And I had just installed a new mz65 expansion chamber exhaust pipe clone. And a CNC high compression head. Right off the bat starts right up idle's great. But While I'm riding and start to give some throttle the rpm's are pretty high. But like I was saying little past half throttle it just starts breaking up . does anyone know what the problem is?
So as soon as you added the pipe, and the head it started acting up? Make sure there is nothing you may have changed during installation like a bad electrical connection, or melted wires... After that I would go back to the stock head and see what she does. If nothing changes re install the stock pipe. We need to make sure we are not having an issue with the upgrades. Also make sure your head gasket is not leaking, your squish gap is not much bigger than 1mm, and for good measurer change your spark plug.
Sooo, going back to what you said about putting the magnet in -backwards- and still having spark.... Where would this spark be? Would it be the same distance from TDC, but opposite, or would it be 180 degrees out?
Asking for 'Academic' reasons....
At TDC the keyway on the crank should be at 1 O-clock
When set on a table the keyway for the mag should also be at 1 O-clock
@@LAHover Thank you. Thinking about it some more, I realize that reversing the magnet wouldn't change the timing at all, just the polarity of the voltage generated by the magneto. (edit: no, that's not even true. It depends on the alignment of the magnetic poles to the keyway)
To do what I want, I'd need a new keyway cut on the magnet stack.
Argh, but that still wouldn't work, because the drive sprocket would be out of position and the chain wouldn't feed.
Sorry, new enough to this community to still wonder "Can I just turn the engine around to drive a main crank freewheel rather than getting a jackshaft setup?" But no, you'd need an engine crankcase that's made as a mirror image to a regular engine.
Let me get the thing built first, before I start thinking about mods, eh? :)
One more thing - I'm really envious of the trails you have available to ride on. I don't know of any similar trail systems around here (New Orleans area) that are available to motorized bikes. I've ridden my regular bike on the Mississippi River Trail atop the levee, but that doesn't allow powered vehicles.
L.A., l built my last bike with a Kent frame, the Phantom 85 has not over powered the frame. I get 55mph out of it. Just make sure that you have front suspension. Bikes By Bill.
I have a walmart bike with a hd wheel from grubee would you trust that? or would the 85 eat the frame
*its a steal frame too
This motor will slowly kill a cheap frame. May last week's or months. Not recommended, I'd looks at a yd100 or wildcat pk80
I need one of these bikes I can't make this bike ride on my regular bike anymore I get to winded
Is squishgap the distance between the center of the spark plug and the end of the bent piece?
The distance between the top of the piston @TDC, and the lowest section of the head.
Larry Shaver....Google piston squish band- image the picture is very descriptive.
if you stick a small drop of grease in the crankshaft before you install the key it wont get pulled by the magnet
I love the idea of those gas bike frames, not that I can get my hands on one anyway, but I'm nervous about aluminium frames. I've not had great experiences with aluminium. My Mk4 (green bike) ended up chewing out the rear wheel dropouts. I took the grinder to to smooth it out and it happened yet again so I retired the bike
I know the color is called "Brushed aluminum" but hopefully is steel, or at least a quality aluminum alloy. Thanks for the heads up!
You're gonna like that faker frame man, they're real light and strong. Can't wait to see both the motor and frame done
It's growing on me. Had the change up the seat and bars tho... To dang tall for that racing stance lol
@@LAHover Yeah man, try BMX parts, like the Stem and Handlebars, you can trust that stuff (it's a hair stronger than MTB parts), and there's about a half inch more room for the extra brake and the throttle. Man i wish YT had pics, lol I think I went too far on mine but its sick as!
The height thing I tried all kinds of stuff but in the end I chose to change my actual riding style on the faker, it's kinda like riding an 80's enduro almost, so leaning is more scary but I got used to the height pretty quick, and I noticed you run a MTB tread for most of your builds, try MAXXIS HOLY ROLLERS, great half-half tire with awesome performance on street and dirt, and they last too, I noticed with the knobbies I lost quite a bit of turn confidence, so I switched.
anyways man, sorry for the book, I just get excited when someone mentions the Fakers, I friggin love em!
@@zachgrabow9541 i would love to see your bike you should make a video
to hold your shaft take the plug out and feed a cotton rope into the cylinder leave a handle on the outside then bring up to tdc. rope will lock the cylinder.
The girth of your exhaust pipe is very intimidating sir 😅
LMAO
LOL>....
Random question does it really matter which way the piston arrow is facing
In general the arrow will always point to the exhaust and the piston ring pins will always be on the intake side.
I have only seen ONE piston with the arrow and ring pins on the intake side, and that is my new Wildcat PK80...
Trust the pins, not the arrow.
I had enthusiast when was younger, but my doctor gave me a shot & it cleared right up. I just don't have enough dimes to get a 85 yet. I'm workin' on it. We had a hurricane & it's a bitch to ride because of trees & stuff.
Hover I know u have issues with the chain tensioners so I figured a way to make em pull away from the engines.ok u kn how we all put the bottom of chains on em instead of doing it that way take the top part of chains a run em under the pulleys and set it to the highest it can go and they will never Loosen up again
I don't know if there really is anything on the market that stronger than a steel frame Kent or Cranbrook. The Phatmoto frame is reinforced, but even that's made out of aluminum. I would think the best thing to do is to take steel frame Walmart bike and bring it to a welder to add support.
Sadly I think you may be right, reinforcing a cheap steel frame could honestly be the best way to go. We will see how to new build works out...
$800.freaking dollars for a bike without the motor?Wowzaa.I do see that it has some really great options,but wow.
I have seen 212 Predators on those, so they must be sold.
@@bryduhbikeguy The $3,000 up to $10,000 name brand mountain bikes are a complete rip off. If people refused to pay those prices, the prices would dramatically drop....A $5,000 MTN bike is going to be way better than a $300 Scwinn Taff but nowhere near $4,700 better. I can understand a Pro MTN biker who makes a living riding paying $10,000 for the best of the best but at $5 & $10K the bike should be all Titanium alloy and carbon fiber.
old road bikes and big bmx bikes do me well. good, strong steel frames
Lol wheelie story. Been there done that. Day 2 testing ebike build. It did a wheelie. I didn’t even have rear brakes hooked up at the time.
Was it Gas BIKE or PIRATE CYCLE that was selling after market performance magnets??? I still have the original one I bought how many years ago it amplifies the spark and retards the timing. When I use that magnet with my jetted carbs the bikes really haul ass for me. I want to find them magnets I have 2 builds right now that are really disappointing to me. I have ZEDA80 that just does not build the power like it should. I am gonna blame it on a bad pickup magnet.
Good question, I'll have to look around and see if I can find one.
@@LAHover Keep me in the loop please. I can look today some it's raining but I have to deal with my insurance company on a medical issue and that takes up half my day sometmes
@@LAHover Oh by the way I wanted to buy a Phantom 85 and Bicycle engines is out of em at the moment. Something about bad bearings. I am gonna give em call now. Let me know if someone else has em.
Did you ever find out What the double squish gaskets were about? Because mine also came with two also. Thank you for the videos and for always awning me back. Great reviews and content
I like your idea with the frame though that's a good choice
Would you ever consider converting your yd100 to a phantom 85 ?
When they release the top end kits yes :)
See things like this is part of a hobby not having to fix part that blow up after 1 -6 rides.a hobby is where u do upgrades when u want not cuz a brand new engine blows up lol.. for this I guess I melt in the sun blaah hahahah 😉👍👍
From Ken himself: The phantom 85
There is a lot to talk about.
As many of you have already seen several failures already.
In this post I'll show what I have found that is wrong with the engine that is on my work bench and in my opinion what is needed to fix some of the issues to hopefully make this engine usable.
Squish 1.8mm :(
Soft bushing in the rod :(
Intake port to wide it will snag the ring :(
Crank not balanced properly :(
Port timing is fair but room for improvement :)
With a simple piston and rod change these issues can be fixed.
With a piston and rod change it has resolved ,
Ring snag.
Squish .
A port timing is nice.
Also can be used as reed or nonreed setup.
the piston ring never runs over the inlet, atleast its like this with all 2stroke engines i ever built. to wide exhaust and transferports will kill your piston ring, but theres a limit which idk
