Here is what I know at this time. The current owner is a very nice man and told me if I'm not happy he will refund the down.
1) Cam chain has been adjusted by a Honda dealer. Was told it was tight. We know the level of motorcycle mechanics today. I'll take that with a grain of salt.
2) Asked the level of noise on a scale of 1 to 10. He said maybe a 5.
3) Noise stops off idle. Can here a slight noise when backing off throttle.
4) I'll listen to it when I pick it up. Could be any number of things after doing some searching here. Poor adjustment, stuck tensioner, carb sync (I doubt it however), loose rear chain.
Appreciate eveyones help. I really want a 350F, hard to find one that is not trashed but don't want one that needs the engine split. Would be a Sunday ride bike for me.
Thanks everyone.
