I just ordered an HMF slip on exhaust, HMF jet kit, and UNI air filter. My bike’s engine is stock and I’m at sea level. I’m looking for help on a starting point for the carb.

From what I’ve read the basic HMF jet kit consist of only three different sized main jets and the stock main jet is a 130. What main jet should I install after the mods? And should I adjust the needle and air/fuel screw, if so, which settings?

I’ve jetted a KLX250 and a WR450 before but there was a lot of great starting points listed for those bikes at different elevations and engine mods. But Im having a hard time finding details on the carb for the Rancher 350.

I understand this would only be for reference and I have to read the spark plug to make sure I’m not too lean or too rich. I’m just looking for a good starting point.

I have also emailed HMF direct asking the same questions and I’m waiting for there response, but I wanted to ask here as well.

Thanks in advance for the help.

And I will post up pictures of the mods and install once the parts come in.
