_any suggestions on how to get the garelli going faster? its totally stock_
It seems that a Garelli takes a bit of work to improve.
I've removed the airbox, smoothed, chamfered and port-matched the cylinder ports an intake manifold, brazed up a midimoto expansion pipe to fit and up-jetted.
I've not gained much top speed: 32 mph according to a "This is your speed" road-side speed detector, but top end acceleration is improved a bit. The bike will do an indicated 40mph on a slight or steep downhill, which is presumably rpm limited.
I'm going to try improving the exhaust-cykinder interface a bit and redtrict the muffler tailpipe size to try to bring the powerband down a bit.
