Hello.. my yamaha dt r 125 cut out when i was riding.. tried to kick start it and its jammed.. im thinking could the power valve be causing this ? thanks
SOURCE: fuel for yamaha dt 125
This bike uses unleaded gasoline. At only 6.7 to 1 compression you can use the lowest octane fuel you can find. 87 in the US is what that would be around here, but across the pond the octane numbers are different. But don't forget the two stroke oil. That may be more expensive than your fuel cost.

Your barrel? LOL. Sounds like the valves need to be gone through. I would suggest taking and valve train apart and put it back together correctly then go from there.

yes you do need a battery, the best position for thr power valve is half open, then once its started turn it either open for bottom end power or closed for top end,i think that right it might be the other way round ant quite remember, but half open should be best for it to start
