I know a lot of you must have had the idea of shoving an engine into one of these huffy cruiser bikes, it looks too good to pass up right? Anyways, I have had some problems in my endeavors that I would like to ask for some help. First the engine chain keeps rubbing onto the side of my rear tire. I have flipped the sprocket to give me a little more room but its still a little close for comfort. Second, it was hard for me to install the break arm after putting the sprocket in the rear wheel. I had to really tighten the whole thing down for it to even fit in there. Then the break arm kept rubbing onto the nuts for the Sprocket Clamp Assembly. Has anyone had these same problems? Also, have any of you guys tried putting a front brake on this bike? Thank you very much for your help. This website has really helped me out a lot, it has been a great guide and resource.
