I think the rubber rolling thing is a chain tension device that supports the chain about half way to the sprocket.

Dont see how that would keep it from rubbing the tire

Any ideas?

New tire maybe?

I had to go down to a 26x2.00 tire, it still rubs a little bit but not enough to worry about. Some guy's use a 26x1.90.....

Mine came with a rear sprocket that was bit offset. If attached to the wheel the wrong way it would move the chain really close to the tire. I turned it over and it moved the chain a little farther away from the tire. Don't know if that will work for you or not. Just a thought..........................

yeah from what I've read the sprocket has a bit of an angle to it. Check and see if yours is point in towards the wheel. If it is, remove it and flip it around and see what happens. If not, a smaller tire, or I wonder if some sort of spacer could be rigged up.

I assume you've gotten the chain on alright, with the master link pointed like an arrow, with the blunt end facing in the direction of chain travel and the open end away? OK. The chain tensioner with the plastic-like wheel bolts onto the bottom the chain, the slack side, typically bolted onto the horizantal part of the frame between the pedal and rear wheel....may need to remove chain links if it can't get properly tightened. I had a 2 inch rear wheel and it rubbed, had to go to a 1.5 inch tire to prevent rub...but pinch-flatted every single ride.

Did you get the clutch lever figured out? When it's pulled, it should look like the picture previously given to you, and the engine sprocket should spin fairly freely.

I had similer issue, You have to do what you can. mounting the motor a few milimeters to the side can help. I had my rear sprocket on and off 3 times till I got it the way i wanted. Actually cut a thick rubber gasket as a spacer between the rubber spacer and sprocket. it brought the sprocket out a little. I then put 1/16 washers between each side of hub and rear dropouts. helped the chain clear frame too.

I am heading to a motorcycle repair place to have them take out the links. I could not get the links to punch out, much to the chagrin of my fingers.

I would estimate that I am 20 hours into this lil job.

I have the clutch working properly, I should have the chain working this afternoon, the big test is whether or not it will run.

Thank you guys,

From deep in the heart of Texas!!!
