Get a Roller blade wheel with Abec bearings and and some flat washers and make a new Idler wheel. You will need to cut a small grove in the wheel for the chain to ride in. I use a drill press and make a lathe out of it and a chisel to make the groove. Enjoy the ride..
If you look at that pic. That idler wheel is on the power side of the chain. Not good. You can put a wheel on the power side to take up chain lash when slowing. But..It should be spring loaded. To put a wheel with no give on the power side is not the best. Enjoy the ride..
Well I made a atempt at the roller blade wheel. I made the groove which is good. I put it on the bike but when you tighten it. The wheel wont spin so the chain just drags across it. How do I secure it so that the wheel will spin with the chain? Dac you made it sound so easy just get a couple of washers yeah then what? I put the bolt through the wheel with a couple of small washers on both sides. What am i doing wrong here?
Well that looks like what i did except I put it were the old pulley was I dont want it on top . I am looking to put it were the old one was. That bolt looks no different than the one i was using expect for that one is longer. I didnt have that many washers either. It has to be tight otherwise it just falls down and the chain gets loose which defeats the whole purpose of it.
