Harris=aerox Posted May 23, 2012 Share Posted May 23, 2012 I de restricted the bike and added in new rollers ( 3.3g ) and also added a stage 6 pro replica exhaust, it trys to reach 30mph but cant and only reaches it goes down hills, but when it does reach 30mph the stage 6 exhaust kicks in and it flys right up to 50mph. I've had this bike for a year but it was sitting outside my house for 6 months of that year and ive only really been riding it 4 months. I fitted these things after i went 500miles and they were fitted the other day. Can anyone tell me whats wrong with it and why it isnt getting up to 30mph ???? PLEASE HELP Is it the spark plug ?

Moderator DirtyDT Posted May 24, 2012 Moderator Share Posted May 24, 2012 Hi and welcome to the forum. You really need to post a decent "hello" here and then ask a question in one of the sections you can find at the bottom of the home page. That said, have you rejetted the carb?

Moderator Cynic Posted May 24, 2012 Moderator Share Posted May 24, 2012 Its overgeared. The exhaust doesent 'kick in' on a 2 stroke. Piston speed, airflow, port timing etc combine to create sweet spots generally know as power bands and it sounds like yours is out of sinc with the gearing. Tune the engine even more, at your own risk and expence, or swap the rollers for a different set. Link to comment Share on other sites More sharing options...
Aerox Owner -GreenMachine- Posted September 3, 2012 Share Posted September 3, 2012 hey, when i baught a leo vince zx pipe for my 01 plate aerox i found i had the same problem.... upon consulting the 'doctor' (my dad) lol there was a washer/restricter in the downpipe by the head. remove that and you will notice a big difference failing that, buy a air filter, reeds and up jet.
