I can't remember exactly the price, but I'm pretty sure it's less than $150: Send your carbs to CrazyPJ to run on K&N 1850 pods. It's a relatively cheap performance upgrade that will net you quick and obvious results. Not too hard to get the bike to blast beyond 105 - 110 mph with this one upgrade. When you get the carb modded, also get heavy duty cb350 clutch springs from Bore-Tech. They're really CB500 springs. There are several oil system fixes that take care of the 360s oiling deficiency. Look at your engine's serial # plate. If it's got two dimples, then it was likely done in the 70s. If not, buy a CJ360 pickup on eBay to take care of the bike's issue with idling on the side stand. There is also a well documented oil mod that PJ has shown many of us. It's in his 360 thread, as well as mine and Trek's. Check your cam chain tensioner and make sure you have the post-recall version. If not, or if yours needs replaced, then order a set from Sparck or Common-Motor. I believe Common-Motor gets theirs from Sparck. Common-Motor is a great resource for 360 owners, btw. From there, you have a great base for a fun scoot. If you want to get into bigger displacement and performance cams, I would do this other stuff first.
