OK well I have run some cheap stuff through and will for a little while longer but it's time to get serious. I will probably rack up a lot of miles on my little 400 this summer so what oil (Money is NO object here, and for an air cooled old motorbike one loves it should never be!), so what do you guys suggest? I'd love to go synthetic but are there synthetics that are OK with a wet clutch? I thought if I went natural, I always hear a lot of good stuff about Castrol GTX. I also remember researching it a few years back and finding that most oils sold as "motorcycle" oils are just a way to charge more. In any case it's been a while since I had a bike I loved, so, what do you guys suggest?
Edit: I just read an article that says that synthetics causing clutch slippage is actually a myth, and that synthetics will prolong clutch life, so I think I will go synthetic but not likely motorcycle specific. Brand suggestions? Should I go with a Castrol synthetic? Over the years it's the one oil (along with maybe Royal Purple) that I consistently hear spoken highly of in auto parts stores.
