Hi ........... One tooth less will give you more top speed (if you can pull top revs) but will reduce accelleration. If you go for one tooth less you'll need to tighten the chain and/or remove a link. It's a trade off ............ decide what you want the bike to do.

Not much to start with here unfortunatly mate. A free flow muffler will help top end speed, change the factory airbox to a K&N style pod air filter, other than that, hugging the tank at top speed :) If you do change these parts, you may also need to increase the main jet size to richen up the mixture for better tuning of the motor with the better flowing parts. This bike has a top speed of 100kmp and produces 10 hp, so you may only expect to get at best less than 1 extra neddy, and perhaps another 5 km/hr.... I suggest upgrading to a bigger machine of you feel the need for speed :)
If its 125's you are into, test drive a Honda CBR 125R 6 speed fuel injected 13.4 horsepower, and good for 120km/hr

If the bike just suddenly lost power but it still ran, I would suspect the carburetor slide diaphragm provided it still has the original Keihen CV carb. If the diaphragm gets a hole in it, the slide will not go up and down in the carb.
Remove the air filter cover and air filter so that you can see inside the carb. Standing away from the mouth of the carb, rev the engine and see if the slide moves up and down. If so,it's fine. if not, the diaphragm has probably got a hole in it. To get to the diaphragm, remove the carb from the engine and remove the top. With the top off and the long spring out, you can easily remove the diaphragm and the slide. When replacing, be very careful not to pinch the new diaphragm.
One other thing that it could be is something has caused a restriction in the exhaust system. This would probably only be possible in the case of single mufler system.
