Ive recently fitted one of these and measured the port heights and the blow down seems all wrong. do I need to raise the transfers to get this in spec? is this a common problem?
also what rpm is peak power on these kits as std? I have no tacho atm.
and what ignition timing can I run at.
i'm currently at 0.8mm whilst testing
I have a cheapo 32mm inlet jarmacol fuego pipe on a 30mm ID header which is better than the std puch exhaust but will eventually make my own to suit my specific needs
My geared moped only needs a range or 3000 rpm to go through the gears.
