Jet advice

blanc12 · 04-19-2018, 09:40 AM

Hi All
New bike runs like crap. So I need to jet the carb. First I ordered a mikuni form Amazon and jets from jetsrus.
I am sitting 400Ft above sea level in a cold climate. I was thinking of starting with 27.5 and 110 jets.
Bike is stock.
Do you guys think this is a good starting point?

The only other problem I have had with it is the headlight. Need to find where the bad connection is. its either on the bulb or connector as it is on and off with a wiggle of the wire.

Going to love this bike. it is already fun to ride even if it runs like crap.

Thanks for your input!

Please tell us which bike and engine you have. That makes it easier to suggest jet sizes.

That's why it's always good to put what you have in your sig and what mods.

I would say that your starting point on the jet sizes is a good one to begin with. I ran essentially the same setup on my Hawk when it was stock in warmer temps and found it to be a bit on the rich side with the 110 main, so in a cooler climate it should work out well.
