Hiho first of all! I have a hercules Gt and wanted to make it hot. I put a little charcoal on my side and want to do something with it. only how do I get the cheapest to more kmh or ps,??? cylinders etc. and where do I get the things best? At goetz I already looked and found a tuning cylinder. but it is expensive. and how much ccm bracuh do I get for a good performance. What bracuh am I doing??? so I don’t want to spend over 200 €, Thx! already in advance!!!
