One of my Yamaha SR500s that was super fast , had a 540 big bore,ported head,cam,etc . Well anyways one day it ate a exhaust valve while chasing a friends Harley XR1000 at the end of a long straight at about 105 mph. As I was coasting to a stop I let the clutch out to see if engine was locked up, it was ! When I tore the engine down valve head stuck on piston,damaged head,bent con rod! Noticed that the cam sprocket was adjustable, can't remember but cam & sprocket came from the same company,might have been White Bros. Engine was from a half miler flat tracker, wow it was fast

Sure made cam timing changes easy. Put it on about 20 years ago. Can't remember who made it. Wish a similar piece existed for the Savage.

JOG , It was a engine I bought for 200 bucks, compression was good , adjusted valves & cam chain & oil change, pulled out another engine that burnt a valve cause header split open on the freeway and didn't make it home, tossed that engine in just to ride it for the summer,that bike went everywhere for 3 years before it gave up under some severe conditions, my buddy with the xr1000 was always amazed that the faster he rode,he always expected to look back and see me still looking for a window to open to pass his asss,but that day he looked back and I wasn't there !
Was a great engine for 200 bucks , yes I said wuzz
I heard it back fire when I backed off wot and yanked the clutch in just as rear wheel started to lock up, that back fire saved my asss that day !

Armen, It had three bolts holding sprocket to inner hub. Back then I knew what it did but had no idea how to adjust it. Possible that you could machine one from 2 cam sprockets,making inner hub out of one and sprocket out of the other,three threaded holes and three elongated holes.

Reply #23 - 10/09/16 at 18:13:51 Hey Ruttly, I have a spare cam sprocket and will take it to work tomorrow and see what kind of trouble I can get myself into Part of the problem with cam sprockets is that they tend to be hardened and a PITA to machine.

Reply #24 - 10/09/16 at 18:26:52 Armen ,I always thought they just hardened the area where the chain runs. Just another one of my crazy ideas. I think thats how the one for the SR was made the sprocket side looked stock and hub looked to be faced up !

Yes, I always cover the clutch when riding stupid fast,that split second it takes to move your finger over the lever and pull it is too long when things begin to go wrong. Engine failures at speed can kill you , it's not like a regular crash ,skidding or loosing traction , it's a violent slam on the ground when rear wheel locks throwing your weight forward. Weight transfer to front wheel sometime causes the death wobble , real hard to recover control. Yes backfire at speed yank the clutch in,something has gone wrong !
I know our bikes backfire,but mine doesn't with that 36vm mikuni,not at all.
Took a riding skills course for off road,teacher made us ride the motor cross course and thru the woods with one hand,your clutch hand had to stay tucked in your belt !!! That was tough.
