I got the kitted a-55 sprint, tecnigas pipe, 22 rear gear and 27 front: both upgraded, and a #55 jet. I was wondering what the top end difference is cause with the stock air flow restricted pipe and no big bore kit the thing went 27 digital (cyclometer) and when it actually revved out to past the air flow restricted-(probably 5300) RPM limit, it really growled and said about 36 on the stock speed o, witch is really about 33 (digital). that's got me thinking maby the kit wasn't worth it. I figure with just a bi turbo pipe and the right main jet,a 27 front, and the stock 29 rear gear combo would be close on the top end!! But the kit does help reduce stress and does accel fast. Also, does my #55 main jet sound big enough? I was told that's the a-55 stock. I would figure my 70cc kit would take more but I think my temp on the fins feels good, and so does the plug look a good cream coffee color! Thanks for replies!! (kitted top speed is 42 digital)(70cc Airsal kit)
