Is a 138 jet possible?

[Honda2000]

Ok, i bought a few jets to hopefully make it runn a little better. i bought a 158 16 and 165 from my local stealership. i pulled my old main jet and it said 138, but it was on the bottom. the jet also had a screw head. when i took the 138 out it was bigger than the 165 that i had? how could this be? Also does anyone have any jetting reccomendations, i live in the middle of kansas, thanks.

You have a Dyno Jet jet kit installed. If you want to go back to Kehin (hex style) jets, you'll also need to remove the piece that the jet was screwed into. You may also want to buy a stock Kehin needle, since the kit comes with a different taper needle. You could probably run it, but I'm not sure how it will affect performance.

i bought a few jets i put the 165 in there and it seemed to work alright. it screwed in just fine so. i guess i just need to get different jets? thanks for all of the information!!

[Honda2000]

jordan mg i have almost the exact stuff on my quad, maybe 175 is where i might need to be

[Honda2000]

i have a quick question. I have a 185 main in right now and it seems to run just fine. My question is when i am too rich will my motor hardly run? wil itt just fall on it's a@$ when i;m wot. THanks

[redexrider]

if you are too rich, it will not be as snappy. Your throttle response will not be at its peak. Just check your plug and make sure it is "running fine". That is the only real way to know if it is running right.

i pulled my plug and it was a white looking color. It means it is too lean yet?
