Hi everyone,

I am new here, have to say this is a great site. Very imformative.

Here is my concern, I recently built up a 1986 YZ250 and love it, the only problem is the very hard hitting power band. For the first 1/4 throttle the engine is very boggy and spits out tons of smoke(seens extremely rich), then after 1/4 throttle it hits like a bullit. THe bike just rockets off.

Is this normal for the old 2 strokes or is there something going on here? Is there anyway to smooth out the HIT that i get just pasted 1/4 throttle?

Thanks

Mike

Most of the older bikes dont like the lower rpms but love to stay at 9 and 13 grand. You could put a flywheel weight on to tame the powerband and give some low end power.
