What elevation are you at. your main may be a bit small.

at sea level

if you back out of the throttle a little on on the topend, 5-6th, does the power pick up a little? what is the gearing/tire size?

[damoz]

i have not notcied it pick up if i back off ....um the tire size is stock i havnt touched them since i bought it new.....also i know the boys at my local motorbike shop lifted my needle up 1 clip

If you run your bike without a rad. cap does your coolant circulate when you rev your engine?If not you may need a new impeller if it doesn't circulate very well or if not at all you could need a new gear.(the white plastic one under the clutch cover.

i have had all that checked and it is all running fine

Then your detonating.

[damoz]

wat do you mean by that??

[bonerific250]

he means your probably running the wrong fuel. whats your comp? and what octane fuel are you running?

[damoz]

i run 32:1 ....i think its 95 or 98 octane premium

[AKheathen]

Then your detonating.

so, enlighten me......how do you know this? most likely if the needle had to be richened, then the main could be lean. what is the chamber size? stock head uncut?

[camatv]

hold up now you say your bike overheats very quickly AND it only goes 106km per hour. so your saying your top speed is low WHILE its overheating??

 

am i the only one here or what.?

 

if your blasting it down the road while its pissing coolant out all over the place you probably need to up your main but you have probably also hurt something else due to the overreving and overheating. if it over heats just general riding around i BET your water pump OR your radiator has an issue. have you washed your radiator out?

[damoz]

no i have a trailtech fitted to my bike so i watch the temperature and keep it under 100 degrees but the temp only stays down if i ride the bike slow and stay off the revs........but when the temp was down to about 80 degrees i was trying to see how fast i could get it i tryed 3 times over the day of riding and the max speed i could get it up to was 109km
