jetting recommendation

[polako]

hey guys, just joined the forum

i own 96xp , 15f and recently bought a REAL jetski superjet 650:arms: :arms:
when I took it for a ride I wasnt really impressed with overall performance(all stock).
I decided to buy Coffamns pipe for 650.
I am about to install it this weekend and want to know what to do with carbs.
I used search option but couldnt find nothing.
should I run the stock needle and larger high and low speed jets.... can anyone help me????



thx for all help.

If it runs well now and you're adding only a pipe, then you should need a slightly larger pilot jet and a slightly larger main jet. If that.

hey Matt another stupid Polak question,
slightly larger?what are the stock ones on 650?
and where can i order all this?
I dont really want to go to SBT and spend my money there
I would rather help other company , not that SBT is bad....they are just like PPG in my Polak dictionary

OEM should be a 120pilot and 115main.
But there's no guarantee that's what's actually in there.
So check it before you order.
Order jets that are 2.5 bigger than what you got, i.e. a 122.5 pilot and a 117.5 main.
You may very well find that you'll go back to the previous jets - there's no telling at this point. I have no experience with that particular pipe.
Maybe one of the resident pros could jump in here.

I had these bookmarked from before if you're talking about the Coffman Sizzler pipe. Mine had a 120 P and 135 M when I got it, but it was a little rich by looking at the plugs. Ran good though.

Kawasakis are JetSkis.
Yamahas are WaveRunners.

Welcome to the forum. Great pipe. Good luck.

SuperJETT is another jetting guru. I'm sure he'll chime in.
