What RPM do you reach 344? Geared like that you should rev at around 12k to hit 344. If you're close to 14k, your clutch is probably slipping.

13300 rpm at 344 kmh. I have brocks heavy duty springs. But if clutch slipping - it would rev into 14000 rpm limit? But it doesn't happen.
Can it be of bad quality fuel? In russia we havent got e85. Only 100 octain premium. But in tests it shows only 97 octain. We have 116 Vp racing fuel. But it cost 10$ per liter...

Could be your tuck, could be head wind, could be DA, could be your weight and body position, could be the slope of the road, and the distance. There is many factors to going fast.

I weight a lot. ))) 100 kg = 220 pounds. But i thought it isnt important for max speed. Acceleration - of course. But top speed? Aerodinamics... i touches my helmet to fuel tank. Difference is to big. 344 and 400... my friends said that 400 in Turkey it is a fake. Isnt it?

You need 19 - 37 gearing to hit 250mph GPS!

I did 238.1 mph GPS on PUMP gas in one mile with stage 3 gears and head / cam with 19-38 gearing and was at 13.9k rpm.

400 kph on speedo in Turkey was FAKE as is any speedo reading!

238.106 mph GPS Autobahn - Pump Gas

With a smaller tire you will probably hit 14k rpm, speedometer will show higher numbers, but the real speed will be basically the same of 200/55 at 13,3k.

It doesn't matter if you touch your head to the tank when your shoulders are in the wind. You arnt missing anything, it just takes more than you think to go that fast. It's not as easy as people assume it is. This is why people become humbled when they go to a legitimate event and get a reality check.

The 400 is fake, but so is your 344, but both are equally represented by the same fake speedometer reading. You arnt actually going 344. You are really doing about 325kmhr
