Hi All,
So I finally got my new-to-me JTR250 up and running.
I'm new to trials bikes, but not to motorcycles.
It starts great on the choke (the little black lever pointed up vertically), and will idle all day like that.
The thing is as soon as I put the choke lever down, the engine bogs and eventually dies out. ;(
I'm imagining the carb is running too rich because i think the choke on this carb restricts the air flow during start-up, and as soon as I remove the choke, the amount of air in the mixture is too great and the fuel is not compensating....
I started with the air-mixture screw at 3.5 turns out and the idle is a few turns out too.
I just cleaned the jets and carb.
I didn't pay attention to the needle postion...:/
Thoughts?
Who sells a rebuild kit for this carb...? I am in the states.
Thanks!!
