been working on this thing for 3 weeks bout to give up chain and sprocket issue

Insignia707 · #1 11-07-2008, 04:17 AM

So i might be a dumbass but i havent gotten the motor running yet and i've run into some problems already. I finally got the chain tool to put the chain onto the wheel sprocket and the engine sprocket next to the clutch. So I hopped on my ride and tried to pedal, the rear bicycle wheel moves only like a half cm when i pedal. So I stomped and jumped on the pedals and literally put all my weight on the pedals, then the rear wheel moved like an inch. so i took the chain off and used a socket & ratchet wrench to try to move the chain sprocket in the engine without the chain, it was hella hard to move the sprocket and took a lot of upper body strength... it was the same way when i fed the chain through. It's a two stroke raw gas engine. I'm assume that theres something wrong with the engine sprocket? If you can help me that would be awesome of you.

Do you have the clutch hooked up & disengaged? Walter F.

The engine is hard to turn because of gearing and compression. You still need to hook up the clutch and then you'll be able to pedal the bike with the clutch lever pulled in.

when i read your replies i didnt have it installed, i just put in the clutch just now... it still doesnt work. I dont know if i put the clutch pin/bolt in the right way in the engine sprocket cover. The clutch pin/bolt is cut into a half circle, does it matter if the flat side or the round side of the clutch pin is next to the bolt connected to the engine sprocket? I know that the spring/tension is at a decent tension, the clutch moves a 1/4" when i put the clutch in when i tried to pedal. The chain is tight as ****. I readjusted the chain tensioner to get better clearance for the chain and to get better tension. so what the **** is the problem?

WHAT HAVE YOU BEEN SMOKIN'? You don't have to install the clutch, you hook up the clutch lever/cable to the clutch actuator arm, What you have described is a "woodruff key" which goes rounded side down, flat side up and is used to drive whatever is on the shaft it's in. WHAT ARE YOU DOING WITH A WOODRUFF KEY. We got to have pictures of the patient before we can go any further, You'll get it, for now you might be better served to NOT touch anything, unless it is to turn it over for pictures! DON'T FRET Walter F.

You may want to check whole clutch cable set-up. Without seeing it, it is hard to tell what is wrong. So I will go over the whole thing. You had to take the cluch lever and cover off to put the chain on, then repace cover there is a ballbearing in the in the hole where the push pin goes, check to be sure it is there. The levers's flat side will be toward the push pin when you put the cover back on. The lever will face the rear wheel. Install the clutch cable coming from the clutch handle bar lever that is on the left hand grip side. The larger spring is a heat shield and goes over the cable first to keep it off the motor. Feed the cable thru the cable stop that is located on the right top of motor. The thinner spring now goes on next between the cable stop and the clutch lever on the motor. feed cabel thru the motors clutch lever and pull all the slack out so cable is tight. Secure cable while pulling usin the small collar, usin a screw driver. Now check and see that the clutch lever moves in a good ways when you pull the handle bar lever. sometimes it takes more adjusting. I hope this has helped.

by the way some1 told me to take out the spark plug... apparently there's no compression in the engine when you do that. did that & still cant pedal? so what now?

If the clutch is working, it would not matter if the engine was locked up, it would still pedal. the clutch must work to start the motor and also to be able to stop the bike. So check the clutch set up

I know that it's hard to diagnose & fix the issue over the web but i took what pics i could & i appreciate it guys & i wasnt talking about a woodruff key, the half circle thing i was talking bout is in the 2nd to the last pic. It was hard to get the chain on a women's bike frame with decent clearance, so i used skateboard bearing's for additional tension, but i dont think that should be a problem. also this is my first build... I'm really clueless... so be nice if you can cuz ive been at this for 3.5 weeks now & I REALLY JUST WANNA SAY FOOK IT & GIVE UP.
