Jetting question

Hey there I'm new to this site and bought my first X2 this summer and love it. I already need more power though. It's a 650 I have a Mainer pipe and waterbox Westcoast head 29cc domes dual 38 Mikuni on PJS manifold with Ocean Pro filters on top. Been buying this stuff all summer and just put it on the first of the week. Cylinders intake and exhaust manifold were just cleaned up nothing major. I will be running preimum fuel. I have not ran this with the Mikuni's on it yet was not even sure of a starting point any help would be great. Love the site too!

[green_white1]

I'll work on getting some pics. I've got a bunch of ideas for this winter. Cant believe I'm saying this but I am wishing for a winter with little snow so I can work on the X2 instead of sleding. Not sure of jetting now but I'll check it out tonite.

I checked the setup currently in the carbs I bought.

100 mains
75 pilot
2.0 valve
I think brown spring not sure what colors there even is for springs
silver arm
High 1 turn
Low 1 1/2 turn

Just wondering what jetting I should start with for 650 with Mainer pipe and waterbox WC head? They are Mikuni 38 duals on PJS intake. Any help would be much appreciated.

No one out there has a set of 38 mikuni's on a 650 that can help me out with some suggestions???

Duals on a 650 are a waste of time ...... Get a single 44 on that thing.

This might be a noob question, but what advantages does the single 44 have over the dual 38?

Easy to tune , half the cost for the setup as well as to rebuild carbs , use less gas , better bottom end with a single(debateable) . If your running a 650 and your looking for more power a dual setups not the way to go , a 750 setup is. The power difference between a single setup and a dual setup on a 650 is not noticeable. Might be noticeable in different parts of the power range depending on your mods but not a "Holey Crap" kind of difference.

Also I like having the room under the hood on the 650 setup.

Oh yeah , getting at the mixture screws on duals can be a beotch.
