Ktmkray455 Posted November 14, 2012 Author Share Posted November 14, 2012 Hi, I have a yamaha aerox 2 stroke and I have just changed the piston and now it will only star full throttle but still with full throttle won't rev up at all or even move, any ideas thanks.

Grouch Posted November 14, 2012 Share Posted November 14, 2012 You need to do an intro in the new members section before anyone will answer you. It's considered good manners on here. Just tell us what bikes you have and where your located. Link to comment Share on other sites More sharing options...
blackhat250 Posted November 14, 2012 Share Posted November 14, 2012 Sounds like a carb -fuel problem, did you put it all back correctly, and is the piston in right way, ^ to the front, . Link to comment Share on other sites More sharing options...
Ktmkray455 Posted November 14, 2012 Author Share Posted November 14, 2012 I have put the piston in the right way and fuel is getting to the carb and all jets are clear, float is fine, just had new spark plug, air filter and ht cap but still won't rev, it just about starts but only stays running with full throttle but even still with full throttle is revving out to about 2,500 rpm, thanks for the suggestions Link to comment Share on other sites More sharing options...
