Hi everyone.. hoping to find some help here... I have a superbyke rmr 125 and have fitted a 150cc big bore kit.

This one.http://www.ebay.co.uk/itm/151947456016

With this carb.

And this air filter.

I have blanked off the egr and completely removed it and added a filter for the breather which was attatched to old air box.

Now to my problem. The blasted carb setup!!
The carb originally came with a 100 main jet, I adjusted the air screw to get the idle set and the revs to go up and down quickly and responsivly when open and shutting throttle.
Great.. no problems. Took a little time but good.
Test run.. throttle a little baggy at low revs, but moves up 7.5k without too much effort then... bogs out like being flooded or starved.
So.. I change jet from 100 to 110.. lmao.. the thing wouldn't go past 2k and struggled to pull me along..
I have now put in a 95 jet from the original 22mm carb that came with the bike.. it can pull to 8k before bogging out and has a little more power in lower gears. Still no where near as much power/pull/torque when it was a standard 125cc.
Surely I can't need to put in a smaller main jet than the original 125 carb and block needed? To make this bigger cylinder work properly.
Other posts I have read suggest 110 or 115 main jet.
Any suggestions appreciated.
