    RMZ450 Jetting

    Well I can tell u all that the bike run like a bat out of hell with no jetting changes...no back firing up or down and starts on 1st of 2nd kick all the time.... FMF 4.1 Full Tit system w/Magabomb.. twin air filter with out screen.. That setup changed the whole bike bottom to top BIG TIME !!!!!!

    Which pipe for a 07 RMZ 450?

  4. I could use some advice on jetting changes for my bike.. Here's the info: 07 RMZ450 stock motor, Twin airfilter w/out the hard screen, FMF Factory 4.1 full titanium system with megabomb header.. I ride MX tracks in FL. Have adjusted the fuel/air screw in and out to find the best place that it doesn't stumble off idle..(But it still has a good stumbel in it.. going thru the gears it seams to run good, But i have to think i need a jetting change from stock ???????? I have ordered a FMF jetting kit for this week and just looking for someone who has this setup and cound same me alot of time R&Ding..... Thanks for any info.....
