Alioth Posted April 1, 2010 I have an 05 and an 06 450 but for some reason if i start at a dead stop with both, the 05 will kill the 06, the 06 tachs out extremely quick, theyre both timed Identical, and the sprockets, tires, and valve springs are all identical, any ideas? Im going nuts, I also changed the CDI boxes on them and they both do what they were doing before, 05 flies, 06 slow, any ideas would be greatly appreciated, thanks alot Share this post Link to post Share on other sites
yubamike Posted April 1, 2010 Are they both stock? If you haven't had them both since they were new, I would suspect the 05 has had the cam mod done and the 06 hasn't or it isn't jetted correctly. It is really amazing the difference uncorking the exhaust, removing the airbox lid, the cam mod, and some jetting can make! Share this post Link to post Share on other sites
Yamchick Posted April 2, 2010 But the cam mod would make the 05 rev faster than the 06. The 06 is slower and tacks out faster... Share this post Link to post Share on other sites
