Bsr36 3x3 mod, mrd ssw, jd jet kit, where to start with jetting?

Recommended Posts

Recently picked up a 00 400s with 4k on it. It had the 3x3 airbox mod stock exhaust uncertain if jetted. I bought a k&n filter, jd jet kit and mrd z pro. In my research before i bought parts, i found some info on jetting but can't find it for the life of me now that parts are here. I live in south west fl so almost always hot and humid and at sea level lol.

Follow the kits instructions.

+1 there, it's pretty simple if you follow the instructions that's came with the JD kit.

After my install I found my main was too small (based on my # of turns on the fuel mix Screw) but your able to twist the carb and swap the jets with it in the bike still so no big deal if you need to up or down a size after you run it for a while.

good luck!!
