Hi , i am getting an 2008 yz450f next month and i did order an aftermarket
full exhaust system, i gave the dealer 3 choices whitebros ,dr.d or fmf..
does all of these have a possibility of the mega bomb header...
and what jetting changes have u done who lives in +30 celcius at sea level..after installed a pipe like that...i have several pilot jets and main jets (coming in mail) so i dount think i need the jd-jetting kit...and wich carb mod is best..power bowl (from r&d), powershot(scaryfastracing), zip-ty racing but i dount feel like sending my carb from thailand to america and wait for a month to get it back...and not be able to if power bowl as good so then it sounds like a good idea....:thumbsup:

White Bros is now Vance & Hines.....
FMF is powerbomb
I would look at DRD or Arapovic if it was mine

Regarding carb mod - get bike jetted first and ride it. Then determine what is needed.
On my 06, I am sold on the Zipty full carb mod with the R&D Powerbowl - they can sell this entirely....but you need to start talking to them to see if they will ship to Thailand

have ron hamp bore your carb, the yami carb is much smaller than honda and others, I gained low end and tons of over rev by having RHC do my carb.
