Super Jet Installed Factory B Pipe....need help with jetting?

[moose]

We just installed the Factory B Pipe on my 2004 SJ today and we need to know what size jets to change out to? The elevation that we ride at is between 4,500-5,500 feet, depending on which lake we go to. Also, does anyone know the recommended settings for the high and low screws for this scenario? Any help would be much appreciated!

Might need to lean out the hi and lo screws a 1/2 - full turn.

Factory recommends;
Main Jet: 135 (130 stock)
Pilot Jet: 70 (stock)
High speed screw: 1 2 turns out from closed
Low speed screw: 1 1/4 turns out form closed
Needle & Seat: stock (55 psi)
Spring: Stock (95 gram)

Would you go with a 135 MJ and a 70 PJ at 5,000'+ of elevation??

Having done so in the past, yes.

My brother has had a factory pipe just sitting on the shelf since 2006. Crazy right?

We call that a wise investment.

I just got the Mod Factory Pipe for my 2000 SJ and so far its all stock. We normally ride at less than 1000 ft. It looks to me that Factory pipe recommends 145 Main and 120 Pilot. Does this sound right or am I missing something? It doesnt seem to be inline with jjk8's recommendations. Any help would be greatly appreciated, it seems the info I ve gotten all varies and I just want to get this thing on over the weekend.

Factory pipes instructions are not the best. You are reDing the mod directions, which list a 44mm single carb, yet dont explain it, and says other jetting may be needed for a modified engine. The mod pipe is for modified racing engines...

The 38 jetting is in the limited sheet. My motor with a mod pipe is setup at 75/140@18. Not sure why my motor likes so much mroe fuel but it runs great.

Thanks for clarifying and pointing that out!
