i just bought a 2000 m2 with a k&n carbon fiber intake. the bike also has an unknown after market muffler that was cracked and re-welded by previous owner who said most of the packing was lost. anyways the bike runs decent but i checked the jet sizes which are 200 and 42 with the mixture screw still capped. does this sound right or should they be changed?

Sounds about right to me.

Pilot should be a 45 with the uncapped screw out 2 1/2 turns to start. A 200 main is on the big size for a stock motor.
Most run in the 185 - 195 range depending on the part of the country you are in.
My M2 has a 190, my son's S2 is a 185, mine is a 190.

I run a 200 main and 45, with the mix screw 2.5 turns out, stock motor with intake and exhaust upgrades. 4,500-5,200 feet here for my my general riding duties including the local canyons.

The 42 (stock) slow jet is a little lean for most applications isn't it?

My M2 was very happy with a supertrapp IDS and a 45 slow jet, and 195 main. I am 600 feet above sea level.
