84 CR500 Chain Tensioner Spring ?

Anybody know of a source for this spring . Mine broke and is gone . I've been trying to make something work but have not found a viable replacement yet . Bike RIPS , handles decent , turns heads , barely stops , and takes a divine act to start cold ( even with some of the mods I found on this great site ) . I love it . Thanks .

Theirs at least two venders for new springs (but Ouch at $24 & $28) Check ebay or I might be able to dig up a used one if you want.

Is the spring the same on a 84 WR250? I got one for you if it is.

Thanks guys . I just snagged the first one I've seen , on ebay , for $10 .
