Hi there, I have had a search for the answer to this but not found one that really applies to my bike, unless I have ,missed it...
I have a sputtering at high revs, as soon as i reach just over 40kph.
Here is my set up...
Polini Banana Exhaust
Polini 16/16 carburettor and manifold kit
New 24/72 primary gear
I may have my jetting wrong so can you suggest a main jet I should go with?
Also, what kind of speed should I be expecting if I get the jetting correct? It feels like it has more power to give.
