I'm going to pick up a White Bros E-Series Slip-on and need to know or have a good idea what jetting I should run at sea level. Should I buy the dynojet kit or am I better off just buying the jets separate?? I heard that the 27.5 pilot jets take care of the carbs popping off the boots?? If anyone installed an E-Series Slip-on please tell me whats jets your running ETC. Am I going to have to change the needles??

Thanks Chris

 

i have 27.5 pilots and mine still blo off,i safety wired them down at the race saturday, just in case,i got jets from 140 - 170 and mine raptor is still finiky sometimes,i mostly motocross my raptor i got it perfect in january, but now it is warming up so i will probably have to go back and try it again,my jetting and my mods are in my signature this might help you,but i am not sure with a slip on

 

My friend just put an E-series on his and he didn't have to change anything. We are at 450ft. above sea level so not much difference there. We haven't had any problems with carbs blowing off on ours. His bike sounds sweet now. I'll have one soon.

 

I just bought an Exhaust system from HMF Engineering with a jet kit. The whole system including jets came to $419 shipped. It's a great system and makes the Raptor run like a Raptor should. I ride at Pismo and have had no problems. See the dyno chart at www.hmfengineering.com.

 

HMF is not a big company and people are overlooking them, but I must say once more people but them then go out and ride people will be buyin them. This system is great. You gain as much power with them as any other company may 1 or 2 less but the price is awesome alos.

 

E-Series was one of the first mods I made to my Raptor, good choice! I did not have to reject until I installed the ProDesign filter and FMF Powerbomb header pipes.

 

hi i was wondering how you like that fmf power bomb header..becasue iw as thinking about getting it to

 

Dont go with the FMF head pipes. They are no differant form the stock. look at the size oof them compared to the other manufacturers.

 

Thanks for the link SteveReno, I've been looking for and hearing good things about the HMF muffler for the Raptor. Only one question remains...How Loud is it? Thanks,,,

 

I really can't tell you if significant power increase were obtained from the PowerBombs, since I installed Dynojet and ProDesign filter around the same time. I got them mainly for the looks and if I happen to get additional hp or 2, that's gravy... :-)
