    another clutch mod

    In addition to my previous clutch mod, thought I'd go one further and improve the clutch arm cable connection. I used a hose clamp for this one, straightened out the metal and cut, drilled and bent into shape. This prevents cable flex as the arm moves in and out and potentially reducing...

    Clutch Clutch bevel wheel rattle

    Hi everyone, I recently bought and installed a 80/66cc 2 stroke engine with clutch lever. After a few uses there seems to be a rattling noise coming from the clutch bevel wheel. I've tried to tighten the central nut keeping it in place but it already seems tight. Has anyone else experienced a...

    Do any of you know of a good website that sells the clutch assembly (gear, bevel, bearings etc pressed together ready to go)? Not looking for the spring or the shaft just the main clutch gear with everything in it. So far I have only found websites that offer it but are out of stock. If you know...

    Bike accelerating without using throttle

    Hi, I've got a relatively new (3rd tank of break-in) 66c motor that has a weird issue. I just installed a new expansion chamber banana exhaust because I broke the stock one, and something I've noticed is that once I start the motor and let out the clutch, the bike accelerates relatively fast...

    Clutch arm issue

    In sure this is somewhere if someone could point me in the right direction. After messing around with the clutch from both sides. The pin that the lever actuates seems to be sticking out too far. Forcing my lever to be in the wrong position. Tried to make it move anyway but it's not budging/I...

    I think I have a clutch issue

    So I’m fairly new to motorized bikes and I’m building my first one. I already took part the clutch box and experimented with it and I realized the plate was too tight. So I loosened the flower nut and the clutch plate and reinstalled the camshaft and clutch lever when I realized I might have a...

    Disengaging clutch while in motion?

    So I was riding my motorized bike the other day. I'm going about 15 or 20 mph and I decided to squeeze my clutch lever to disengage the engine. I was trying to stop but something weird happened. It happened really fast so I'm not really sure what it was. It made an odd noise and my bike tilted...

    Clutch and Throttle (problems?)

    I just built my brand new 49cc 2 stroke bicycle last week, and tried to ride it about half a mile. I'm really pretty sure it should be operating differently than this? what happens is the clutch DOes disengage and the bike rolls freely, until I let go of the clutch, and the engine starts just...

    clutch revs instead of letting me coast??

    Hello, can anyone tell me what I'm doing wrong here...? I've heard from my experienced friend that: while my engine is running, I can squeeze the clutch lever to just coast and hit the brakes at the same time if i want. Yet, when i squeeze my clutch, it just revvs way up, way too much...

    Primary reduction and clutch question

    I am looking for a primary drive reduction for the 79cc Predator. I am finding some that have a plate that bolts to the engine around the 5/8" output shaft but do not know which ones are more reliable. Is the Max-Torque clutch the one to get? I am seeing several others, some that are tuneable...

    Hi Everyone, Having a bit of a weird problem here as my clutch won't fully disengage so when I pull the lever in I can still here the plate spinning on the pads. At first I thought it was my clutch lever touching the frame and loosening the cable but it is fully tightened and has little free...

    Engine dies when clutch is disengaged

    I just got this kit a week ago, today I finally got it running. I had to buy a better spark plug. When I let go of the clutch the engine dies. I tried adjusting the idle screw and that didn’t work. Any help is appreciated, thanks.

    Here's a real Head-scratcher

    Just mounted a new Zeda engine onto the frame, hooked up the cables and then the drive chain. Next, I engaged the clutch to roll the bike forward and after a few feet it locked up (mind you, its never been fired up). At first, I thought the bikes lower crank assembly froze so I pulled the chain...

    Chain rubbing cover

    Hey! I've been perusing these forums for the last month or two and finally got my first 66cc kit in the mail today so I figured I should finally join in. Anyway, upon mostly installing my kit(for the life of me can't find an Allen key to move my stupid twist shifters) and noticed the rear wheel...

    Clutch Cheap and best HS142F Clutch & Bell?

    I've heard that the clutch in the 49cc HS142F 4-stroke kits may not be sized properly to the bell. I've heard that two solutions are to buy a heavy duty clutch with larger springs, or to buy a bell that is ~.250" smaller. Can anyone provide links to the cheapest and best solutions? I'm aware of...

    Centrifugal Clutch Fix?

    My clutch bell just detached itself from the small gear cog. It seems as though it was just pressed in, no solder or weld marks on it. If not fixable anybody have any luck on purchasing a decent quality one lately?
