Jetting specs, is your setup like mine? Loooking for a baseline

[redroost85]

Ok the long short of this story comes a need to truly rejet my 400...not just the main jet. I am switching to a Uni with the lid on this time...as opposed to running the K&N with the lid off.

Right now I have a 165 main, and the stock pilot 38(?) I am at sea level. I have a full Yoshi pipe and the motor is stock.

Does anyone have a baseline or just a place to start thinking about mains, pilot, mixture screw, needle, etc.....:o

I will just be using stock Keihin jets too.

Any help is greatly appreciated.:( :)

this is just a starting point. if it isn't running to its potential, let us know and we can do some fine tuning. however, you bike should run great with this jetting setup. good luck
