After two years of restauration and riding my GS150 1961 for a while I would like to go a little faster and having a quicker acceleration ! I already bought a sip road racing exhaust.
No I'm searching for a racing cylinder or kit, but in the SIP web shop Icouldn't find one suitable for the GS150. Are they there anyway ? I prefer a plug and play cilinder because I want to keep all as original as possible !
Especially I was looking for a quattrini cilinder because I saw something passing through at youtube ! Maybe there are there other options or recommendations ?
Please let me know what the possibilities are. Thank you in advance. Roland
