slingshot is an unknown quantity at this point
Default LT250R,PWK 39.What are you guys running?

Ok, I got my 87 lt250R back together with a whole new list of parts.I started with a brand new jug, sent it to Denny at Flotek for porting and head worked as well. I also picked up a new intake boot from a 500, put a 39pwk between it and a K&N clamp on with a 4" piece of 2 1/2 " pipe to clear the frame.I put an LRD pipe on the exhaust side and Pro Reeds on the other. Right now my jetting is as follows:162 main, 55 pilot, DEL needle. Im still a little off on the bottom but have ordered what Denny suggested. Now Im just waiting for my new needle and pilot. I was wondering if anyone has a set up like this, and what jetting you guys have?

That is the same main jet that I have, I think that I have one size larger pilot. You will be in the general ballpark, Just test & tune when you have it running.
Since then I have added soem of the things in my signature & I havent had it running yet, so I imagine I will be too lean now.

Well, I FINALLY got everything together and started jetting correction. Right now Ive got a 162 main, 52 pilot, clip in the middle. It runs awesome and idles pretty good, but ive got to go down one size on my pilot. It idles best with the air screw 3 1/2 turns out. So I should have it rippin very soon.

Why make power half the time with a 4-stroke when you could make it all the time with a 2-stroke?
