I've just fitted a lambdasensor on my bike, and even with needled and mainjet all stock/stock position, its rich at cruise and WOT.
The idle is spot on with a 50 idlejet (46 stock) and the co screw 4 turns (yeb) out.
So I actually have to lean out the needles and mainjet, from stock setting. (needles in the middle groove, and 13/120 mainjets) They ARE jetted fairly rich, i guess because they're aircooled, and back in the days when they were designed, there was no euro3 standard and such to overcome.
Mines a 2003 if you dont recall, and have airboxsnorkel removed, and installed a little mesh instead, pipercross airfilter, kedo oversize header, and laser produro exhaust.
I was like wtf when i first saw the numbers on the lambda-display, but tings like that dont lie.
