clutch

Hello! Just installed 80 cc from zoombikes, this is my second build and I have to admit I am stumped. This is checking that the engine is ok so no fuel was used in these starts all I was trying to do was get the engine to turn over! When trying to start the bike for the first time it...

Hey all you motorbikers! I love motorized bicycles! I've been running fine for about 2 months, lot's of joy riding & getting errands done in the sun, & I have gotten past the break-in period too. I used to live in Denver, CO where the bike was assembled, & then threw it uptop my parents...

Hi Guys. My clutch has begun to intermittently engage. Typically, I will be idling at a red light with the clutch disengaged, and I will feel the bike surge forward slightly, and hear the sound of a quick engagement. Also, with the motor off, and clutch disengaged, I can push the bike around...

Hello everyone! It's great to be part of this forum, I have read many threads to get to where I am with my project. First, I am a newbie and this is my first built. I have a RAW Silver Slant 66/80CC. 1. First issue I had was mountin the engine to my Schwinn Clairmont 26" so bought a...

Hi all, long time listener first time caller here. So my bike has a 4-stroke hua sheng 49cc engine with the centrifugal (automatic) clutch. Today I was riding and something happened with the clutch so that it changed to being permanently engaged. I would appreciate any advice as to a fix. I...

I am using a 3.5 hp B&S lawn mower motor that i had recently converted from a vertical shaft to a horizontal shaft. (which was not too bad) but i am now stuck on adding a clutch to the crank shaft so that the bike will b able to idle once i start it. Or maybe there in another way to make it...

Ok, so here's the deal, I'm trying to make a motorized bicycle at my house, using just parts around my house. (Except for the broken fuel line). And now ive come to the point in time where i need to have some kind of clutch on it. Ive thought of a lot of different things i could do (roll start...

First time installing...My clutch is so stiff/firm that there is no way my clutch cable and hand lever can pull back the clutch arm to disengage the clutch and allow the back wheel to spin freely. The only way i can disengage the clutch is with my hand and it takes alot of pressure to do so...

Just went for the first spin on my new build. This is actually the second crack at the first build. The original was an attempt in a frame that simply had difficult geometry to work with. That said, bike starts and runs and works decently under pedal power. However as the clutch is...

Sorry don't know what this bolt is for? Smooth like a pin then threaded...Here's a pic. Thank you.

Could someone please tell me what this bolt is used for with the centrifugal clutch kits? I couldn't come up with anything, and it doesn't show to use it in the installation papers form anywhere on the internet. ??? Thanx

I just bought a Grubee SkyHawk GT5 on GasBike.net and I'm having problems with it. I'm not good with engines but I think that I have installed everything correctly (at least to my knowledge). The issue is that when the clutch is engaged, the bike won't move freely. The chain is being pulled...

so this is my first post and my first purchase. I have built a occ chopper bike and everything is in position. I purchased the grubee skyhawk and am so lost on how to fix my problem. First of all my bike only runs if choke is all the way down on the gear shifter style. if i move up at all it...

Hello, I have a Chinese generic 2 stroke engine kit, it's 66cc. I would like to make it run as silent as possible, how do I do this? What do I need? Where do I get the supplies from? I would first like to make the clutch case make less or no sound (right hand side case) please help Thanks...
