Buy a second swing arm off a 450 or 400 from PSN  for about $25 , cut the forward end off one and the rear end off the other , graft the two together and you got a 6 inch swingarm r what ever length you want less then 6 inches ---the drive shaft you can do two ways , take one drive shaft and cut it then have a collar made and extend it to the swingarm length and weld both pieces to the collar , or get two drive shafts , cut them both so they can be butt welded together to the length needed , slide the collar over one side before you weld it and then after welding and grinding , slide the  collar over the weld and weld both shafts to the collar  , that way it is welded in three places

sounds simple enough

Ok guys the noise I was hearing that I thought was my valves turns out it ain’t. I thinking wrist pin slap or timing chain. Got it running and it’s back firing out the carb. What are yalls opinions 

[Fishfiles 20,145]

puffing back thru the carb makes me think timing chain , stuck or bent valve or a  bend rod 

[ThatsNotSmart 23]

It’s got great compression and the valves were pretty much perfect. I’m leaning more toward timing chain. The guy I bought it from said he just got it out the shop from getting a top end rebuild but who is to say that’s true

If the timing is off one tooth then it won't achieve max compression , maybe do a compression test and see -----I have had a exhaust valve stick on me before on a 300 , but it would not start up or run when it did ----- I think a intake boot crack or bad oring at the base of it , can cause the puff backs also
