does anyone no wether you could upjet the cbr has anyone tried if so what jet sizes etc have they used and what are the standard sizes

standard size is a 118 ran 120 with wrc gp system

cool what sort of speeds do you get im not to bothered about top speed but i would like to be able to go uphill with the wind against me and still reach 70 or somewhere close
and looking around the internet most people seem to exaggerate slightly saying they have got 105 out of theirs

i used to acheve 65 up hill with headwind.but im 6ft 2 and 11stone 8lbs so youve prob got an advatage over me.wrc have improved the gp system since then so i would have thought you would be able to get 70 if the wind wasnt extremly strong.i had 85 tops outa mine but that was on a very slight down hill and i was as low as i can get.you mite get more with dif front sprocket but this will affect acceleration.

there speed figures are rubbish lol.

youd be better with sach,stronger more powerful engine 4 valves instead of cbrs 2 but there is the water probs it has

il see what the acceleration is like before getting the sprocket was that 85 with gp system i am about 5"9 but weigh 13 stone so will probably be similar to your speed

is the performance of the gp sytem and the uthe side system the same
