Having cut and brazed an expansion exhaust to fit:
and re-jetted with a 66.
I'm wondering what I can do to get the most out of it? ie. higher rpm and better acceleration.
I've been advised to advance the ignition and check the jetting. Any more suggestions?
The more forcefull exhaust note from raising the compression seems effective. Gear down to get on the pipe earlier also
Fully advancing the ignition has given more urgent, punchy performance. Drilling out the carb jet with a 0.7mm bit gives a more confidence-inspiring chocolate-coloured plug.
As it's a singlespeed, Gearing is a bit low, if anything.
I've heard mixed reports about head skimming...
Would reducing the tailpipe diameter improve the low rpm torque significantly?
Reducing the diameter and lengthening the header will give you better bottom end but hinder you top speed. try doing a little clutch tuning to get into your power band faster.
