Do you need to replace the jetts on buying E series Exhaust, for my Raptor?? or can i go with the stockers?

 

You will need to bump up by several points to get it right..... I will ask my friend who got that pipe.... give me a day or so to get the answer for you

 

Cheers desracers, I would buy you a beer, if i could!!

 

well, When I had my wolverine, i put an E-series pipe on it.Plus i put a dynaflow jet kit in it also, however, my friend put a FMF pipe on his wolverine and never touched the jetting. He never had any problems, But I think it has alot to do with how many disc you are going to take out or put in the spark arrester,try calling white brothers and asking them..........Nailer [img]i/expressions/face-icon-small-smile.gif[/img]

 

It depends on whether you do airbox mods. You will need to do this if you want to see any real gains.

 

Yes, just start high on your jetting and work your way down. Don't richen up your needles though....rich enough in standard position. I have one and would recommend one. You will get a nice gain from an exhaust on the Raptor.....but the other 50% comes from jetting. The question is.....how bad do ya want it?

 

I have both the E-Series & the R-Series that I switch between on my Rap. Go ahead & change the jetting you will be glad you did!!!!

 

I ran an e-series with 16 discs, k&N filter, no lid, 160/165 mikuni jets. Ran good.

 

I have the E-series with 13 disks, 145/150 Dynojets, snorkel flaps cut-out, and 2 1-1/4" ports in the airbox lid. Seems to run great!

 

I first bought the E slip on for my Rap, and I put it on without re-jetting first (that's the easiest right?). I ran it around the house for the day and then checked the plug... I decided that I would NOT ride it again until it was jetted properly!! My plug was on the white side.

When I later bought the K&N filter, I also had to jet up one size. Later on, I bought the WB headers and Dyno Jet kit (best thing I did at this point).

After that (6/22/02) my tranny blew, and the "rest" (in my sig) came at that time! hehe
