this bike makes me excited. it is quite possible that there is either a cam chain idler gone bad, or the cams can get gobbled up to to any number of reasons; these bikes are as indestructable as our niners, and have power numbers close to par for our 919s also! if i remember right, about 43 hp stock... or ballpark 95 hp/ liter. not bad for 37 year old tech!
I hope someone picks it up for parts or a project!
