I have a problem with yamaha aerox 50cc cylinder, but the exhaust is Gianelli shot that was intended for The cylinder for 70cc .. Can someone suggest me some solution, because my problem is in very bad acceleration and a bad start. End speed is great ..
(over 80 km/h)
Does anyone have experience with standard aerox 50cc and 70cc exhaust Gianelli shot?
Acceleration is poor, and the uphill is very slow (20-30 km/h). I think the problem is in rapidly changing gear, that lose power ..

Do i need to change variator, rolls, clutch or something?

Please tell me exactly what i need to change

Nice looking scoot watch your spark plug for leanness.

The 70 exhaust is designed for a 70 which would have a larger flow than the 50 so you have less back pressure which hurts the bottom end performance . The 50 exhaust port is not fully opened up where a 70 it is bored out round instead of a D shape .

Mine came with 6g rollers and I never had any problem going up hill . I tried 4g and it was too light so I mixed them to equal 5g . A larger main jet can help it run better . A BBK will have more power . Now when I put a BBK on mine with a PM Racing pipe bottom end was less since it was open exhaust with no restrictions but top end I was zooming !
