Yeahhhhhh, finally got jetted nice and proper..

Recommended Posts

......for 41F ambient temps that is.

I've been fiddling and fiddling, got close, but still have a low speed stumble and now it pulls smooth all the way through.

168 main

38 pilot

JD Blue 3 or 4th clip (I got it written down in my jetting notebook)

A/S out 1.25

She now pulls nicelyfrom off idle all the way up. I'm a happy camper..for this time of year that is.....and I'm sure my neighbors are happy that there's no more 2 smoker flying down the street doing high speed plug chops.:bonk:

I think I could go another jet richer on the main, but I don't plan on any high speed runs for the rest of the year. The club rides are over and there's no place on the trails nearby to grab that much throttle.

I'm loving that bottom end pull now, the throttle response is crisp, crisp, crisp!!!

58 pilot seems HUGE. Stock is a 35. I'd heard of some folks going to a 38, but never a 58.

That's about what I run around here in the desert on my 250 for the winter:

162 Main

35 Pilot

Blue Needle in #2

AS at 1.5.

Your jetting seems to make sense to me -- the 300 is sure to be a bit thirstier than my 250.
