I have a Puch Maxi K, and it does 30mph.
What are my options for adding parts to increase speed?
I don't really want to increase the engine capacity, as it'll annoy my insurance company and the police! - (I'm restricted to 50 cc while I'm 16). Could you tell me what the new expected speeds will be? I've seen the Biturbo and some other exhaust, but still unsure which will be best for the money. Will a new exhaust generally require a bigger carb? I heard this somewhere. - cheers.
