Default Re: Tensioner issue solved for $5 and a hacksaw

the advice i like to give is to get rid of the idler pulley.
if you have nothing getting in direct line of the chain you will have less problems.
it took me some time & several times remounting till i found the perfect position to get both chains tensioned well.
it may take a half link on the pedal side. you will mostly focus on shimming the rear motor mount.if you have horizontal rear drop outs, adjusters can help keep the wheel strait while setting up & using.
they can be picked up @ any bike shop.
i have had the idler go through my spokes & the chain break & get snagged. just like i have read from other people.
i got rid of the idler & used 415 roller chain. i have not had one problem since.
i still have not run across someone that wrote about how they removed the idler & somehow it reappeared in their spokes. lol


that flat iron would make perfect shims if they are cut into several peices. & you have bolts that are long enough.
