Chain problems with eng swap..???
I swapped the enging from one of my bikes, now I have a problem with the chain "walking" off the rear sprocket to the 'inside" of the sprocket between spokes and sprocket. I set the chain on the front sprocket and the rear sprocket to "eye" up the "run" . The small front sprocket is further "in" and causes a "diagonal run" which throws the chain off.... how can I remedy this?... I tried to remove the front sprocket thinking I could "shim" it out... never did get it off... then I thought I'd remove one of the washers off the rear wheel but after consideration I realized that would not change the "relationship" of rear to front sprocket... anyone have any solutions? who has experienced similar issues?... remedy?..... thanks
