Re: Got problems, please help!!
I would not ride a bike that has broken or missing mounting studs, except to get it back home. Having only one mounting point will cause too many problems, it can break the studs due to flex and it will make the chain come off. Vibration will be real bad also, do not use rubber between the mounts and frame the engine needs to be solidly mounted. On a new build I install the tensioner at a location that suits the frame, usually close to center between engine and rear sprocket. Roll the bike while watching the chain as it roles over the tensioner, if it rubs on one side you need to bend or twist the tensioner to try to get the chain to run center.
Your results may not be the same,Greg
