I was running yamalube 10-40, but I swiched to MOTUL 10-40 (full synthetic)with no problems. Some info I recived from a few Yamaha dealers is why I made the change. S#$T is expensive though alost $8 a quart I think.

 

Golden Spectro 4, currently have 20W/50 but will be switching to 10W/40 for cold weather riding this week. Runs between $6-8/quart. Here is the technical data for the engineers in the crowd or those interested.

I have only used Mobile 1 synthetic automotive. I've had no problems yet, and don't plan on it due to the New Fortin Racing gears going in next week. Also, I've had no real clutch problems as far as slipping goes. From what all the builders are saying, the tranny prob is strictly an alignment deal that is somewhat associated with using reverse. My reverse **** is guarded by Glock! Good luck and send me a message if anyone wants to know how hard the installation is, and/or pics.
