Yamaha Aerox

[dannyboy007]

I have just recently purchased a Yamaha MBK Nitro (Same as Aerox) 100cc 2 stroke.

It has new carb, piston, airfilter, a racing exhaust, new drive belt and i am not sure if the rollers are new but i think they are 12 grams.

Theres not a problem starting her. Starts first time! Kick and electric.

When pulling away she is REALLY slow until she gets into the second gear then she pulls away nicely

It is at about 3000 rpm vibrations start and pulling away is difficult.

I need help to try and resolve this problem as it is doing my head in and obviously going to be p*ssing other motorists on the road especial ones behind me.

Could the reason be that the new piston needs to be run in?

Could the rollers be to heavy?

The belt needs to be used a little before picking up the pace?

Or maybe the airfilter is causing this issue?

Any ideas how to get some acceleration from my baby?

Thanks for taking the time to read this!

Do you use the choke to start it? That could be why.. Check your jets in your carb, and after getting new pistons you shouldnt be driving it on..
