Gearing info needed
I am running a 16 sprocket at the front and standard at the back on my 14,the acceleration is great but the bike will only run up to a 301km/h,if I drop 1 tooth at the back will this still be better than standard gearing acceleration with a higher top speed,has anybody got this gearing on a 14,I use my bike for street riding only.

If I can run a 308Km/h with a little better acceleration than standard gearing it will be great

You don't say how you are measuring your speed or if your bike has enough power to pull max rpm but :-
16/40 should give you 317 kph before the engine rev-limiter. If you only get 301 kph it looks as if you are running into the speed limiter which operates when the ECU reads 300 kph or 186 mph, whatever the gearing. So you need to de-restrict it first perhaps?
If you want to keep the 16 tooth engine sprocket and gear it 16/41 you will hit the engine rev-limiter at 308 kph. If the bike is de-restricted and it can't pull that gearing to maximum rpm then it's not making enough power.
Remember, if you de-restrict with a Speedo Healer you do it by making the speedo under-read so you'll need another way of measuring speed. GPS or the timing gear at the track for instance.

If you could pull the same rpm with 17/42 you would be doing 316km/h. The engine rev-limiter should operate at 320km/h, so you're possibly there - within 1% or so.

I just got off the gearingcommander site.I was running 16/43 last year but the gas mileage suffered and the real problem I couldn't keep the front end on the ground.I got 16/41 now and I'm going to get the GPS out to see how far it's off.I never had my bike over a true 165 mph and that felt scary.Pa roads are choppy and trying to see the end of the sraight is a rush.Some of them go up a hill or a slight bend.My back tire has a few thousand mi left and the next tire will be a 190/55/17 so I'll have to change the Speedohealer again.
