no worries. have a look here:

isn t cheap though. those prices are from the time the aussie was low. you d get a better price ordering from europe where the vm28 is around 150 Euro.
also i do use a 280 jet, not a 260, the 260 still was a tiny bit lean on full throttle. acceleration is the main effect, and i measure that in front shock rebound in 2nd 3r and 4th gear :-)
a 200 is cool. but it may as well be one that rocks...and modding is half the fun :-)
