I just read this on another thread:
" My advise is install a 4 degree offset key to back your ignition timing from the built-in 32 your billet flywheel has that was engineered to run @ a continuous high rpm in narrow power bands on racing engines to a more acceleration friendly 28 degrees unless you plan on racing your mini bike on an oval. Might go 30 on an engine for a broad torque curve build, depending on application, but never 32 on anything not on a track. This is static timing. No advance mechanism like a car. 32 is 32 at idle and at max rpm. You're killing your low and mid range torque with too much advance."
Live and learn, acceleration friendly is what I'm after, think I'll back mine up 4*. Comments?
