I was running Yamalube when I got it, and it didn't smell that great. Changed to Redline ester race oil now and it smells much better! It was set-up as premix when I got it, which is a good idea.
Put a few miles on it yesterday, and it ran OK, but the jetting isn't quite right yet. I need to order a 1 size smaller main and make an adjustment to the needle.
I think the mods we made to the intake manifold helped peak power, as it feels like it's pulling stronger on top now.
EDIT: Got a new float needle and seat, main jet, and a needle jet with a fatter taper (the other was full-lean and still too rich). Also will drop the float level 2mm as suggested by the Mikuni tech. The carb sits at a 30 degree angle into the reed block, which is really too much. 12 to 15 degrees is the recommended max. Not much I can do about it.
