Hi, I just bought some aftermarket goodies and am waiting there arrival. I'd like to give you a list of what I have so once I get it I can start my jetting off within the ballpark of "good" jetting.
HMF slip-on
Lidless with box pre-filter
2 stage Uni
K&N jet kit
ride @ sea level

Any help will be much appreciated as it will greatly reduce my jetting time. I don't know exactly the difference between DynoJets and stock jets but any numbers will help. Thanks
P.S. I have not taken apart this carb (only warriors) so if you know of anything I need to look out for or tricks to it, please let me know. Thanks again!

Thanks, does anyone else have a responce? P.S. I hope I'm wrong but doesn't the jet kit only go up to 180 main? O I hope I'm wrong.
