I dropped in the 750 slingshot cams (I think it was 2001?) I I thought it was worth it. But just the cams by themselves, I don't know. When I put in the cams, I also went to Dale Walkers full exhaust,K&N pods,timing advancer,and stage II jetting. (1st Gen.1200). I'm pushing 40K on the odometer,and runs like a champ. When I feel like its getting tired, I'll do the pistons/rings and maybe some porting,whatever else,not sure yet. I'll wait till the time comes.
