I have a Rally with a P200e engine with ported casings from SIP and a 210 Malossi kit and a Sito-plus exhaust. However, the bike does little over 60mph maybe 65 at a push. It does have quick excelleration, but I'm disapointed with the top end. At the moment I have a standard 24mm carb with a 130 main jet. The engine has the the T5 forth gear and up-rated clutch. Other guys swear they get in access of 70mph which is what I'm looking for as I use it for work and use quite busy roads, any ideas why mine is slow top end?
