i have a yamaha aerox with these extras -malossi mhr rep 70cc kit -stage 6 crank -stage 6 clutch -polini variator -stage 6 belt -yazuni ci6 exhaust -standard 17.5mm carb 88 jet -k + n style air filter one of the main problems i have is that it takes ages to pick up speed.for some the reason the engine seems to not be reving as high anymore.compression is good and carb clean.this problem came all of a sudden after i had been out on it. wondered if any1 had any suggestions.
Work through the trouble shooting guide and you may find your answer. http://www.scootershack.co.uk/troubleshootingguide.html
i looked through the guide and changed a couple of things apart from the rollers,at the moment it has 6gr will changing to 3gr make a noticable difference
3g is probably way too light however 6g sounds too heavy. I was running around 5g in my 70 which was a mhr rep and a c16. You could try 3 3g and 3 6g to see how it feels.
