I put a hotseat Green primary spring in my 04 Trailboss 330 and also the ITP mudlites,which are 24" instead of the 22" stock. I find that I need about 3 miles of straight road to hit top end now. I think that I should change the clutch weights to compensate for the stiffer spring and larger tires, but I'm not sure what size weights to get. The only other mods are the K&N and 130 jet. I have a ton of low end but hopefully can figure out how to get the top end right. Any input would be great. Thanks.

 

My first instinct was to re-gear, but then you said that you have low end, so I'm at a loss, sorry can't help on this one.
