Great at revving with no gear but with gear .........

[syafi]

Ok I had this old bike, Suzuki TRS 135 naked bike.

Once i made a mistake not putting 2T oil and it got jammed, then after a complete engine overhaul, it revv well over 10k.

the throtte rosponse is great,

but when i put the gear and ride it, its real bad, no pickup at all. top speed only 35mph. before overhaul topspeed is over 95mph.

why would it rev great without gear on and be bad once the gear is on?

Thanks, I love that bike

Sounds like the ignition timing is off. The timing can be off a few degrees and actually make it seem to run better than normal.. as long as it's not under a load. When you load it, there isn't enough advance for the acceleration needed. I'd start by checking the ignition timing as accurately as possible before wading into fuel issues.

Also check that the ignition advance is working properly.
