I have been trying to get some answers to my questions for some time now, it seems to me that nobody gives, so this will be the last time i try.
I have got a Malossi 210cc and a SIP performance pipe, im using the SI24/24 carb, it works fine on first to third gear but on the fourth it does not get up to high rpms.
Could this be solved with a racing crankshaft and a light flywheel?
or should I try a bigger carb, the SI26/26??
Hope to get some answers.
Otherwise i just[:drink:]
