i got this bike as a project wanted to make it a chopper but after i got it running and drove it a little over the last worm days of the fall i started to love the bike don't want to ruin anything original on it .
I purchased the bike for $600 rebuild the carbs and front breaks and now i only need to work on the clutch its making noise when not engaged but when i engage it noise goes away hoping to find more help on this site so far found all the help i needed .

I can't speak for the DOHC models but if they are anything like the SOHC bikes, they just rattle. You can put a new clutch and springs in but after a while, it's gonna rattle. I don't think you have anything to worry about but others with this bike will be along with comments.
i might but i don't think so i talked to a few people and was told its the plates in the case rattling , i will take it a part to see it have a new basket and plated purchased on ebay for $12 will put it in in worm day no heat in garage
