what is stock for the front and rear sprockets, whats the tooth count?

I'm fairly sure my used bike is stock, an dim looking to give it some more power i dont need to go that fast.

How can i give it some more stunting power for wheeling without takeing off too much fo the top end. the fastest ive had it was 110, that was quite enough. i generally cruise around 70/80mph

 

16/43 is stock gearing. If anyone was wondering.

I'm planning on going to a 15/46 or 15/47. How much difference should i expect? Will i be able to power it up instead of clutching only?

 

One down in the front is almost like three up in the back and if you do both, you will see a huge difference (Just changing the front is very noticeable).

However, if you ride longer trips, it is a lil annoying due to the higher revs in 6th gear.

 

I just got rid of my o4 600rr for a 636 but I had 14 tooth (-2) front sprocket that worked out good! you can also use a stock F4i sprocket for the rear - they fit and I think they are 2up!
