Hey,

I'm looking at buying this bike. It starts and idles, once you give it gas... it bogs. Could this be just a pilot jet issue. I'm new to four strokes.

please let know what you guys think. If i should buy or not. I don't think its a serious engine problem. Probably needs carb cleaning.

Most likely a jetting issue, is it constant or does it get better as the bike warms up?

Its constant either warm or cold

it only runs with the choke on... once i take off the choke it dies. And I've tried it outside and indoor heated shop.

Eitehr way, I bought it :nod:

$600, all it needs is carb cleaning, front brake perch, clutch adjustment and front tube :)

yeah clean the pilot jet. ALso remove the cap from the fuel screw there so you can adjust it.

Thanks Matt, Yeah , I researched and found that from factory they put on a brass cap so no one can play with the fuel screw.

I have to check my float height after work. Make sure its within .64-.68"

Hello all,

little update.

bike runs well. 1 little issue but i don't think its a big deal.

When you quickly snap the throttle off idle, it bogs. but if you roll it on, its fine. Is this a 4-stroke thing? Or because this is a round slide carb?

I'm thinking Pilot screw needs to go in quater turn ? (too lean?)
