Do not use a hammer or chisel use a 15/16 socket on the clutch flower nut!!!!!!!!!!!!!! Works so much better and you do not beat up your clutch flower nut!
I just finished assembling my bike but when i tried to pedal it, it was very difficult like the clutch was engaged even when I held the clutch lever. So then I adjusted the clutch like in the video and now it spins freely all the time and won't engage. any suggestions BikeBerrycom ?
perfect, i work on bicycles alot and a customer brought one in with this kit, very easy to adjust clutch tension with this video on this model of engine
Nice vid Guys I have also had two engines recently a 48cc GT2B and 66ccGT5 where the plate was just stuck to the clutch pads and used a small slotted screw driver to unstick it by gently prying around the radius of the plate .
Power loss is generally due to the carburetor not being adjusted properly. When you twist for more power, the carburetor is trying to feed more fuel and air through a small jet.
it's easy to see that you're an untrained amateur but you know what I congratulations you have made a video that's a lot better than some of the ones that I've seen. outstanding work I believe you should get an education as far as a technical field and I think you will do very well with that sir. but if you can become a doctor, lawyer, or an Indian chief. or whatever your heart may desires congradulations too you and good luck
hey man sorry to bother you, my bike used to lock the back tire when the metal thing on the clutch was up and it will move freely when down and now it moves freely both ways like its not working right and it wont turn on when i try?
I have a problem with my clutch, every time i adjust and put it back together i can walk it about 10 paces and it locks up again. I've tried adjusting it tight and loose doesn't make a difference. Any advise would be appreciated.
Hey i found an easy fix. Just tighten ur chain and tensioner as much as possible and make sure they dont come loose. Because once it gets loose ur chain gets jammed up inside the clutch sprocket.
Having the same issue, there's a roller bearing between that wheel with the 3 pegs and the clutch pad wheel that appears to be "clicking" and binding smh
The wire for the throttle cable is stripping away trying to assemble it its the wire that you put the springs on that turns the thing on top of wear the chain sits its to turn twords the engine but the silver wiring that you screw down is coming on ravled and the springs are being difficult to put back on
@@pallettownheroes2738 damn, yeah mean and my friend just put the kit on his schwinn stingray chopper and we had 0 problem with the clutch except for that screw that locks the wing nut stripping so easily
Hello, I was wondering if you might be able to make a video on the new centrifugal clutch flying horse engine kit because I am interested in buying one in the future and I'm sure others are too. It would be a great help if you did so. Thanks
Hi, got a used Bikeberry, replaced electrical, and finally got it to start. Was zipping along nicely when it appeared to seize up. I can barely run the wheel to move the chain. Any thoughts on what to do?
hi its me again thx for solving problem with wires but now im struggling to start up engine and i dont know what cause this I have spark now and when im trying to start up i release clutch engine is trying to get on but quick time its dying . before i opened clutch and i had to adjust this cover cuz these sprockets werent moving at all and i couldnt get spark now its all sorted but maybe i put something wrong thats why its struggling to get the engine on now ?
The trouble I'm having is I can't find a happy medium with the clutch. The big and small bevel gears stay still but the clutch pads and plate will turn. Any help would be greatly appreciated.
The three pegs on my motor refuse to turn, they will only go about 1/2" in either direction. I know you said to assist it with a hammer, this did not seem to help move it. Have you ever heard of this problem before/have any suggestions? Thanks
Issues? Please check that clutch pads are loosely fitted in clutch plate. Clean the clutch plates (only) with brake cleaner. Also look up how to increase main clutch spring tension. After hours of adjustments, these changes started up my bike in 3 seconds.
Mine had the spring but i removed it because it would pop out the screw and make it fall/scrape the clutch cover. Is there any problem? I know new engines don't have it, and mine seems to run just fine without the spring,even a little better than before i would say..
Hello, I am thinking to get 48cc skyhawk. is the engine quality good? i don't know much about engine so I dnt want trouble to end up fixing it in future. n is it too noisy n will i b able to go uphill easily?
hi there, did you get your fixed. Im having the same problem. Went into gear initially, now it wont go into gear at all. Stays in neutral. Did you figure out what it was. Thanks
I bought a small Bike engine exactly like this- except it does not say Skyhawk, I did everything you say to do, and I found the Spring in the video at 1:39 (time) is missing. ----- where can I buy that Spring?Are they universal? The Name on my box the bike came in says BGF "Boy Go Fast" if that is any help. I got this back over the Summer and with the Hurricane and other things,Am just now able to put it on--- Thanks.

Hi l have a 80 cc motor l haven't ridden for Three months motor has only done about 100 km clutch seems to disingenuous pressure plate from clutch pads But wether l have the clutch lever in or out it still turns the motor when l go to move it not sure what else to look at
i haven't started the motor yet but i noticed that assembling the throttle to the carburetor the cable was extremely tight. it doesn't seem to fit right... is this normal? also i did the test for the spark plug but never saw fire, how do i know its not the spark plug but the wire box?? HELP!!
Question?I'm putting a 48 back on after getting a faulty engine from zb upon re attaching the chain I noticed the bike moves freely with no clutch cable(always trying to start mode)any tips or tricks for that issue.
Hey man here is my problem. I have tried putting the cover that goes on to the sprocket on the side of the clutch that you were showing in the very beginning of the video but the pin is blocking me from putting the cover back on. I have tried taking the clutch cover off and the plate as well and fiddling with some of the settings. I cant get the stupid cover back on that you took off because the pin is seated way to far out of the housing. I have checked for dirt and grime.. help please!!
My 50cc moped has resently packed up on me and i can't push it freely it feels like its in gear or at least stuck in gear but i'm not sure whether is somthnig to do with the chamber and piston/rollers or whether is just the clutch is stuck in engaged - Please Help! :)
yeah got everything installed- and first time trying to start the bike the chain breaks at the master link, so I bought a new Master link and reinstalled the chain. When I tried to tried and engage the engine to start the bike it just completely locked up. Called bikeberry the guy was real nice he said to look at this video my question is the engine is installed already and chain is on so do I have to uninstall the chain to do this? I guess thats a really stupid question since I just said it is locked up how would I get the chain out?
if I am replacing my square like clutch pads with new ones, which direction do the new clutch pads go in? One side of my pads look checkered and the other side is black......and what if the holes seem alittle too small for the actual pads to fit in.? Is this common? and what do you suggest to make the pads small enough to fit?
Black side up. It's normal that the holes are smaller than the actual pads because they need to fit very snug in them. What you can do is sand down the sides lightly then, firmly press them down into the holes.
Can't get mine to start. When I try to start it, I will pedal then let go of the clutch, and when I let go the bike keeps rolling for another meter or two, and there's is no sound of the bike trying to start, any ideas?
if you`re confused about fuel to oil ratio, you can do what I did , go to you`re local Honda shop and buy a measuring cup for 2 cycle engine oil , you can buy oil there too .
Thank you.I can't keep the dang Nut from the Clutch-shaft tight.I put the inside-star washer in,after doing the first part of the Video,as I HAD to so I Could get 'Triple=tree'loose.>All went well for the first start,and 1/2 block.All tightened and it didn't want to stop.I Had to get to Apptmt.After Appt,the clutch kept spinning nut loose behind plate."Help-Plz'
Gotta question for anyone tht wanna help I just installed my 80cc 2-stroke.. when I let go of the clutch the bike takes off to like max speed.. n the throttle doesn’t do anything like when I turn the throttle it just turns doesn’t slow dwn when I release it or be at a complete stop to idol bike just goes .. what do I have to do to control my speed.. Idk what to do ...
I am completely unable to unscrew the philips screw that locks the flower nut. I've tried a couple days now trying to unscrew it and now its stripped. Any advice?
anyone else who has this issue in the future - theres a tool called an impact screwdriver which uses the force of a hammer hit to turn the screw very slightly, so the force of the hammer is applied while the screwdriver bit is being turned. some phillips are impossible to get out without ruining them any other way
Personally, I would use a pair of needle-nose pliers to remove that nut, not a hammer and screwdriver. There is something odd about my clutch setup right now not sure if the cable needs to be tightened or if that nut that you took off with the hammer needs to be loosened. I had no friction at all thought my clutch pads were toast but when I got into it I realised that the pads are fine and only needed to be tightened a bit but I had to turn that nut to a spot where I could put the screw in and now I think it may be too tight either that or the cable has slipped, any input would be well-received thanks. Also, can anyone tell me how you can test a boost bottle to see if it is doing anything?
I just got my bicycle engine kit to run and I was running it at full speed for about 2 min. When I was doing a tight turn I slowed down and the engine turned off. I held the clutch to turn it back on but in the process it became to stiff to turn. The engine was hot and I was holding the clutch but it still would not spin. Would this fix my problem?
I got that fixed one of the chain was jammed in the engine so it works fine but the engine gets really hot. for a full tank how many oz of oil and how many oz of gas should I put in the tank for the break in period. I did 1/24=oil, 23/24=gas
you remove the top nuts and take off the head first, then pull out the head gasket. Then pull out the cylinder be careful as the piston will be there and just pull it out and Piston should be exposed. The piston has a hole in the middle with a wire there. you need needle nose pliers(Google it they are common tools). and you need to remove the wire. then remove the clutch pin and then you'll easily be able to pull out the piston. the bearings will be in the middle of the rod. you can replace if you wish. that's it put it back together the hardest part is putting back the wire clip in the piston.

so... the screw that holds the wingnut. I found it in between the gears all chewed up.. wtf. I was wondering why it was making weird noises. should I ask for a replacement motor cus its kinda fucked
I cant get my clutch to engage the back tire spins free wether i squeeze the cultch in or not tho i can see the plate move yet no matter how tight i tighten it the back.tire spins free
That's the first time I've heard of that problem. If it doesn't effect your flower nut negatively, you may want to file down the clutch pin. Please do so at your own discretion though, as we are not reliable for this advice. PLEASE NOTE: do so ONLY if it doesn't affect the flower nut negatively, as in, it causes the flower nut to sit and screw back on the clutch pin improperly.
I'm a 72 yr. old female riding my Dewey motorized bike for about three days and all of a sudden the chain seems to lock up and breaks. Do I just fix it with a master link and try to start it or do I have to take the chain off and how do I take it off? Do I have to take the cover off of the part where the chain goes through? Does the locking up have to do with the clutch, as shown in this video?
Theodora Czarnecki Hi Theodora, it could be 1 of 4 things. 1. Your chain may be getting stuck on the drive sprocket. (watch this video) 2. Your chain may not be aligned th-cam.com/video/LvLPprywSPk/w-d-xo.html 3. Your chain tension may not be correct th-cam.com/video/LvLPprywSPk/w-d-xo.html 4. Your idler pulley may have been deformed while riding, be sure it runs smooth.
BikeBerrycom Before I rode the bike my brother in law tightened everything and had to fix some wires, as he was not getting any spark (some wires were backward) and did adjust the clutch, but he went home (up north and I am in Florida), so I am going to try and follow the video. He showed me a few things to do on it, but I"ll put the computer next to the bike. Although I have a Ph.D in Nursing, I'm not the sharpest tack when it comes to this stuff. Thank you for your help.
I have a different problem. The rod that sits at the center of the drive sprocket is permanently depressed, leaving the engine always engaged. It can come out like it should but does not spring out from the engine
Hi Bike Berry, I find your vids very helpful. I have built 5 of these Grubee Skyhawk kits now, and sell them. The last 48 cc I did has a rattling noise in the clutch area. Now I have heard this is "normal" sometimes the pressure plate is out of round or something like that? I haven't opened it up yet, but do you have any suggestions on what that rattling might be? the nut loose maby? The engine and clutch work except the clutch will not engage until the clutch lever is almost ALL the way out. On my 66cc it is not like that. I will try and adjust it this weekend and see if anything is loose in there, but your opinion would be greatly appretiated!
Sounds like something might be loose. Check the clutch pressure plate, the flower nut as well as the small bevel gear. How long have you had it and how long have you been running it?
Remeber too also check your gears for any foreign objects before puting the cover back on. Even the tinniest shard of metal with really screw up the internals of a and engine.
i imagine a comment on this 9 months on is probably pointless but hooking a spanner around one of the studs and jamming it against another (then turning) could give the needed leverage to turn the dooberywhatsit.
Andrew Brady Just finished installing the engine on my bike last night. Probably will take it out on its test run this weekend, then new tires and tubes will get installed as well. Can't wait to get this engine going, tired of paying $50 a week for gas in my truck.
my clutch gear is rubbing on the bottom of the motor case WTF do i do?? i tried this out of spite but no luck obviously is the gear grinding along the bottom Plz help?!
thanks this helped but the other problem was i just had to tighten the cluch cabel so it would disangage the engine and sometime if im starting it will just like try to start but like dies instantly BikeBerrycom
Adjusting your carburetor may help that. I don't know how long you've had your motor, so it's a little hard to diagnose, but if you aren't familiar with carburetor settings or if the engine is brand new, I recommend checking your choke, the fuel line, the breather valves on the gas cap, and the jet needles inside the carb.
ok so its like 4 days old just started for the first time today but when i slow down or pull in the clutch lever it revs the engine really high and doesnt want to stop and the the wing nut thing keep tightening back up to where i cant pedal every time i ride it so i loosen it i start the engine but it tightens again
can't get my bike to start, the fuel valve is open, the choke is up, the white lever on the carb where the fuel enters is up at 90 degrees, the idle adjust screw is about halfway,...anyone have any ideas?
ya i checked and i am getting spark...at first my clutch wasn't engaging and the drive sprocket wasn't turning, i'm readjusting it so maybe that's the problem
Do not use a hammer or chisel use a 15/16 socket on the clutch flower nut!!!!!!!!!!!!!! Works so much better and you do not beat up your clutch flower nut!
21mm works for me
Do not use wrench !!!
I just finished assembling my bike but when i tried to pedal it, it was very difficult like the clutch was engaged even when I held the clutch lever. So then I adjusted the clutch like in the video and now it spins freely all the time and won't engage.
any suggestions BikeBerrycom ?
perfect, i work on bicycles alot and a customer brought one in with this kit, very easy to adjust clutch tension with this video on this model of engine
Thanks that was really helpfull I was looking everywear for videos on how to dismantle clutch and u answered my question
Mines been too tight for years! Finally figured it out thanks to you! Thumbs up
Nice vid Guys I have also had two engines recently a 48cc GT2B and 66ccGT5 where the plate was just stuck to the clutch pads and used a small slotted screw driver to unstick it by gently prying around the radius of the plate .
Power loss is generally due to the carburetor not being adjusted properly. When you twist for more power, the carburetor is trying to feed more fuel and air through a small jet.
it's easy to see that you're an untrained amateur but you know what I congratulations you have made a video that's a lot better than some of the ones that I've seen. outstanding work I believe you should get an education as far as a technical field and I think you will do very well with that sir. but if you can become a doctor, lawyer, or an Indian chief. or whatever your heart may desires congradulations too you and good luck
Warren Qualls - Its funny how you tell him to get an education, but you have grammar errors all over your reply...
Now Go i've seen that as well lol.
Hi could you tell me how to tighten the clutch because i can pedal freely while clutch is on or off
just remove the plate and put it back on,not sure why it haps,but this fixed it
Thanks bikeberry! The pseudo manual that comes with the kit is so utterly incomplete and confused, you've been a great help already! ^_^
Trying this now.. been looking for over 2hrs for a video like this..
hey man sorry to bother you, my bike used to lock the back tire when the metal thing on the clutch was up and it will move freely when down and now it moves freely both ways like its not working right and it wont turn on when i try?
I have a problem with my clutch, every time i adjust and put it back together i can walk it about 10 paces and it locks up again. I've tried adjusting it tight and loose doesn't make a difference. Any advise would be appreciated.
Same unfortunately I'm stumped, perhaps we are supposed to oil the clutch in a certain spot so it stops happening? :/ damn chinese motors lol
Hey i found an easy fix. Just tighten ur chain and tensioner as much as possible and make sure they dont come loose. Because once it gets loose ur chain gets jammed up inside the clutch sprocket.
Having the same issue, there's a roller bearing between that wheel with the 3 pegs and the clutch pad wheel that appears to be "clicking" and binding smh
YOUR CLUTCH CABLE IS GONA BLOW ! WHEN IT DOES YOU WONT BE ABLE TO GET BACK TO HOME!!!
What do I do if the 3 pegs don't spin (even with hammer clockwise)
The wire for the throttle cable is stripping away trying to assemble it its the wire that you put the springs on that turns the thing on top of wear the chain sits its to turn twords the engine but the silver wiring that you screw down is coming on ravled and the springs are being difficult to put back on
well looks like I have to replace the throttle cable
happens quite alo
thanx for this video...i tried tightening the cable for an hour and still it wouldnt disengage. thanx to you ik up and running
Thank you so much. I was having an arm wrestling competition with my clutch the whole damn time
You won right?
@@stupidslave nope, i took the motor off and put in a four stroke with a centrifugal clutch
@@pallettownheroes2738 damn, yeah mean and my friend just put the kit on his schwinn stingray chopper and we had 0 problem with the clutch except for that screw that locks the wing nut stripping so easily
@@stupidslave yeah. But in that regard. Get tap and dye kit. Then rethread the hole for a bigger screw
This video saved my bike. I ordered a pull start because it wasn't starting ever, looks like I don't need it now.
You should make more videos. Concise and well edited. Thanks!
If the motor is engaging with everything else seemingly in order I should loosen the flower nut? Correct?
yes just it is tricky getting it to the right amount of loose tho just have to fiddle with it till it is right i had the same issue
thank you bike Barry this help me a lot I search and shearch for the right video but I couldn't fide it so lets give a round and applause.
thank you so much i had problem with the clutch since i bout it and no servece wanted to help me fix it. once more thank you. all the best :)

How tight should the nut be behind the plate the one the spring sits on
Flower nut is the more correct terminology. Thanks for the comment!
Hi l have a 80 cc motor l haven't ridden for Three months motor has only done about 100 km clutch seems to disingenuous pressure plate from clutch pads But wether l have the clutch lever in or out it still turns the motor when l go to move it not sure what else to look at
Are the gears suppose to rotate when you're pedaling?
how do I idle the motor?
also the clutch doesn't work... it says as if the clutch is squeezed when it's definitely not
i haven't started the motor yet but i noticed that assembling the throttle to the carburetor the cable was extremely tight. it doesn't seem to fit right... is this normal? also i did the test for the spark plug but never saw fire, how do i know its not the spark plug but the wire box?? HELP!!

How do you take off the sprocket from the clutch? The videos on TH-cam only show you how to adjust it
With a sprocket removal tool: www.bikeberry.com/drive-sprocket-removal-tool.html

Idk what to do ...
ExtinguishFires _ 13 sounds like your carb spring is gone or not working properly. Or your carb is adjusted way too high.
this is a bit off topic but, does clutch starting the engine harm it?
the clutch arm is at normal position and the clutch still moves and or not engaging with back wheel???
Thanks bro just sorting my clutch now an i needed your vid to sort it
I am completely unable to unscrew the philips screw that locks the flower nut. I've tried a couple days now trying to unscrew it and now its stripped. Any advice?
vise grips?? grind the sides then grab it with vise grip, don't bust the head or you will have to get a tab and rethread it.

I just got my bicycle engine kit to run and I was running it at full speed for about 2 min. When I was doing a tight turn I slowed down and the engine turned off. I held the clutch to turn it back on but in the process it became to stiff to turn. The engine was hot and I was holding the clutch but it still would not spin. Would this fix my problem?
You'll also need to check your fuel ratio and air-to-fuel ratio as well. what's the ratio you're running?
I got that fixed one of the chain was jammed in the engine so it works fine but the engine gets really hot. for a full tank how many oz of oil and how many oz of gas should I put in the tank for the break in period.
I did 1/24=oil, 23/24=gas
Break-in period should be 16:1 so every 1 gallon of gas, you need 8oz of oil.
Can you guys make a tutorial on how to replace an engine head and piston to a new one.
you remove the top nuts and take off the head first, then pull out the head gasket. Then pull out the cylinder be careful as the piston will be there and just pull it out and Piston should be exposed. The piston has a hole in the middle with a wire there. you need needle nose pliers(Google it they are common tools). and you need to remove the wire. then remove the clutch pin and then you'll easily be able to pull out the piston. the bearings will be in the middle of the rod. you can replace if you wish. that's it put it back together the hardest part is putting back the wire clip in the piston.

BikeBerrycom thx
should the gears turn when you turn the three bolt cause my engine won't start and it's new
+Larry Williba same here, did you adjust the clutch
+Царь бббомба i added a pull crank to it
Thank you this is exactly what I needed to know.
so... the screw that holds the wingnut. I found it in between the gears all chewed up.. wtf. I was wondering why it was making weird noises. should I ask for a replacement motor cus its kinda fucked
I cant get my clutch to engage the back tire spins free wether i squeeze the cultch in or not tho i can see the plate move yet no matter how tight i tighten it the back.tire spins free
great vid. thanks. how did you remove the engine mount studs?
Should you do this when u first buy the motor ?
Definitely! It will save you some headache before you mount it.
That's the first time I've heard of that problem. If it doesn't effect your flower nut negatively, you may want to file down the clutch pin. Please do so at your own discretion though, as we are not reliable for this advice. PLEASE NOTE: do so ONLY if it doesn't affect the flower nut negatively, as in, it causes the flower nut to sit and screw back on the clutch pin improperly.
I'm a 72 yr. old female riding my Dewey motorized bike for about three days and all of a sudden the chain seems to lock up and breaks. Do I just fix it with a master link and try to start it or do I have to take the chain off and how do I take it off? Do I have to take the cover off of the part where the chain goes through? Does the locking up have to do with the clutch, as shown in this video?
Theodora Czarnecki Hi Theodora, it could be 1 of 4 things. 1. Your chain may be getting stuck on the drive sprocket. (watch this video) 2. Your chain may not be aligned th-cam.com/video/LvLPprywSPk/w-d-xo.html 3. Your chain tension may not be correct th-cam.com/video/LvLPprywSPk/w-d-xo.html 4. Your idler pulley may have been deformed while riding, be sure it runs smooth.
BikeBerrycom Before I rode the bike my brother in law tightened everything and had to fix some wires, as he was not getting any spark (some wires were backward) and did adjust the clutch, but he went home (up north and I am in Florida), so I am going to try and follow the video. He showed me a few things to do on it, but I"ll put the computer next to the bike. Although I have a Ph.D in Nursing, I'm not the sharpest tack when it comes to this stuff. Thank you for your help.
Theodora Czarnecki buy a car its waaayyyy more reliable
+bob62065 4 strokes bike engine are reliable too.
can u do this with the engine mounted and built
You can do it mounted, but make sure the chain isn't installed when you do it.
I already did it with the chain on and I worked fine, thanks
I have a different problem. The rod that sits at the center of the drive sprocket is permanently depressed, leaving the engine always engaged. It can come out like it should but does not spring out from the engine
Give us a call at (800)317-0479 and we will be happy to help.
Nice video guys! Very clear instructions!
I have a 66 cc skyhawk and When I hold the clutch in, my bike doesn't move how can I fix it?
Before adjusting the clutch, make sure the drive chain isn't installed. You need to make sure the clutch is disengaged fully.
When i pull in the clutch and release it it is stuck and will not release any help?
Help when i release the clutch it just rolls
i just got my kit all together got it running good but the clutch squeaks so loud when accelerating does anyone know why?
you need to grease the clutch pin, its where the clutch arm is located
Hi Bike Berry, I find your vids very helpful. I have built 5 of these Grubee Skyhawk kits now, and sell them. The last 48 cc I did has a rattling noise in the clutch area. Now I have heard this is "normal" sometimes the pressure plate is out of round or something like that? I haven't opened it up yet, but do you have any suggestions on what that rattling might be? the nut loose maby? The engine and clutch work except the clutch will not engage until the clutch lever is almost ALL the way out. On my 66cc it is not like that. I will try and adjust it this weekend and see if anything is loose in there, but your opinion would be greatly appretiated!
Sounds like something might be loose. Check the clutch pressure plate, the flower nut as well as the small bevel gear. How long have you had it and how long have you been running it?
Remeber too also check your gears for any foreign objects before puting the cover back on. Even the tinniest shard of metal with really screw up the internals of a and engine.
Thank you for the video. worked very well for my situation.
hello.can u use this in a kart ?
this is a great engine but now i know whats wrong with my clutch thanks :)
great vid. now I can fix my problem! thanks
my pegs do not release i used the hammer, what can i do
i imagine a comment on this 9 months on is probably pointless but hooking a spanner around one of the studs and jamming it against another (then turning) could give the needed leverage to turn the dooberywhatsit.
Props for " dobberywhatsit".
How do you fix a carburetor that idles high
Thanks for the help! My three prong thing was frozen :)
Thanks bro you have really helped me here.
How long does a clutch usually last, and is it serviceable?
you can buy the pads for the clutch and so its pretty serviceable
Andrew Brady Just finished installing the engine on my bike last night. Probably will take it out on its test run this weekend, then new tires and tubes will get installed as well. Can't wait to get this engine going, tired of paying $50 a week for gas in my truck.
how to fix the clutch arm from moving out
my clutch gear is rubbing on the bottom of the motor case WTF do i do?? i tried this out of spite but no luck obviously is the gear grinding along the bottom Plz help?!
That sounds like a possible realignment issue or an issue with the crank bearings that's causing it to sit unevenly. Did you order the engine from us?
simply super video........thanks
BILL DRAKE
I was told not to use a hammer to loosen the flower nut. It damages it
this was so very helpful i thank you for making this video.
No problem, Alex. Glad it helped :)
Ok i just set mine up and when i try to pedal that engine tries to turn over and wont let me pedal will doing this help
Yes, but make sure the chain is uninstalled before checking the clutch. Tell me how it goes! I'll help the best that I can.
thanks this helped but the other problem was i just had to tighten the cluch cabel so it would disangage the engine and sometime if im starting it will just like try to start but like dies instantly BikeBerrycom
Adjusting your carburetor may help that. I don't know how long you've had your motor, so it's a little hard to diagnose, but if you aren't familiar with carburetor settings or if the engine is brand new, I recommend checking your choke, the fuel line, the breather valves on the gas cap, and the jet needles inside the carb.
ok so its like 4 days old just started for the first time today but when i slow down or pull in the clutch lever it revs the engine really high and doesnt want to stop and the the wing nut thing keep tightening back up to where i cant pedal every time i ride it so i loosen it i start the engine but it tightens again
BikeBerrycom
can't get my bike to start, the fuel valve is open, the choke is up, the white lever on the carb where the fuel enters is up at 90 degrees, the idle adjust screw is about halfway,...anyone have any ideas?
MrJabber22 Are you getting spark?
ya i checked and i am getting spark...at first my clutch wasn't engaging and the drive sprocket wasn't turning, i'm readjusting it so maybe that's the problem
MrJabber22 Awesome! Keep us updated. I recommended also double checking the small bevel wheel and making sure it's pumping the piston up and down.
