Pilot Jet Increase
 

Hi guys. I haven't been here in a while. Been busy tinkering with my bike which I've changed countless times already.

Here's my bike, along with my friends' during a ride this weekend. Fun ride.

Anyway, any of you ever have to increase the pilot jet? I installed a larger air cleaner and can't seem to dial it right and think I need to go bigger.

Thanks, and safe riding this season!

Beautiful! Good job indeed!

To my knowledge, no one has ever gone above a 135 and that was pretty extreme. I think with just an air filter I was sitting 122.5 or 125. Most people, even with both intake and exhaust done, settle somewhere between 125-130. I would try a 130 with what you have and then dial back the other adjustments.

EDIT: So I see you are referring to the Pilot
We haven't seen a lot of pilot changes. Mostly just some adjustments here and there. What do you currently have it turned to? I mean, either way, as you know, you can just swing in to the local Japanese bike shop with your factory jet and see if they have some larger matching ones. The pilot is always the biggest pain in the ass to get set right the second time though. Good luck, man.

I running with different air cleaner an set my pilot at 2.5 turns an change the main jet to 140 , ask for small mikuny main jet

Thanks gentlemen!

Jonathan, I think I have it 3 turns out.

I bumped my main to 140 from 130. It actually runs really well and feel that I can easily keep up with my buddies. (OK, separate topic).

I'll check things out this evening. Screw in is lean, out is rich, right? Just want to confirm I'm doing this right.

You are correct.If idle mixture screw is on back side of carb,the opposite is true!!
