You have a standard bike?

Standard intake and exhaust?

If so, you should be running 115 front and 118 rear I would say.

Have you had it tested on a dyno/rolling road?

@ Pip = no, the speed limiter is 180kmh and it cuts the rear cylinders
If the CDI cannot "see" the speedo then it cuts the cylinders at 5.5k

So, if your instrument cluster fuse is gone, no power return from speedo = limp home.

@karikeo - where are you in the world? What altitude/environmental conditions?

I am not an expert on altitude but you may still be running too rich even with a full system due to the thin air.

Someone else should know more when it comes to this :peace:

I think you would make it worse, this bike does not like it's intake being messed about with.

EDIT: that is if you have a NC30/35. But taking the air filter out without changing other things won't help any bike that much usually.
