Klx300 Big Gun System Jetting Woes

Recommended Posts

Hey guys, I just bought a big gun complete system and need to rejet. I went on Big Guns Website and clicked the jetting link. I found the KLX300 with the race system and it gave the jetting, but it didnt seem right.

it said:

Main jet 145

Pilot stock

Needle stock

Airscrew stock

Does neone have experience with this system and a similar set up to me?

Or does neone have some advice on where I could start?

I mean, I could buy the dynojet, but i could save some cash if someone has the same setup already.

My Setup

2000 KLX300

BIg gun system

uni filter

airbox lid removed

stock carb

Thanks again :cry::worthy::cry::cry::cry::cry::devil::devil::D:D:mad::mad::D:D

I'm using the Big Gun Race Series with the FSW head pipe. I also have the Dyno Jet. If I were you, I'd get the dyno jet. It does a lot more for the bike than just the mainjet. The special shape of the Needle adds a lot of response across the entire band.

KLX340, Big Gun Quiet series, Uni, No lid, stock carb w/ dynojet kit, DJ138 main. Runs strong, but I do feel the jetting isn't quite right. Might be a tad rich still. Kind of hard to get dialed in. Harder than the stock 300. I laughed myself silly when they insisted I put in a 145. :cry::cry::cry:
