bradw314 Posted August 29, 2011 Share Posted August 29, 2011 Hi, I have just bought an aerox with either a 70cc big bore or a 77cc not exactly sure, it was fitted by a garage and is still being run in by me so it does have a higher ratio of 2 stroke oil. My mates 50cc aerox will do 45mph however mine struggles to reach 40mph at the moment. It has been de-restricted and has a leo vinci tt exhaust. Any suggestions as to why..... it could just eb the higher ratio of 2 stroke oil. Thanks Link to comment Share on other sites More sharing options...
Moderator drewpy Posted August 29, 2011 Moderator Share Posted August 29, 2011 possibly, what other mods went with the over bore? bigger carb and/or rejet, updated variator and clutch? Link to comment Share on other sites More sharing options...
bradw314 Posted August 29, 2011 Author Share Posted August 29, 2011 I'm gettting the list of what else has been upgraded but the things i can remember are the exhaust, carb re-jet and polini rollers, there are a few more bits but i haven't had the list through yet. Thanks for your quick reply. Link to comment Share on other sites More sharing options...
bradw314 Posted August 31, 2011 Author Share Posted August 31, 2011 Would there be any other things that could have effected the performance? Link to comment Share on other sites More sharing options...
Moderator drewpy Posted August 31, 2011 Moderator Share Posted August 31, 2011 if the bike can rev, I suspect that the tranny is not matched to the power charactistics. I assume you checked the spark plug colour, it should be light brown indicating the correct mixture. Link to comment Share on other sites More sharing options...
