01 Busa power loss

[hobbot]

Hi, guys! I'm from Russia.

Got problems with my Busa 2001. It's ok riding in the city, changing speed and rpm. But on the road, cruising on 140-160 kmh 4-5K rpm, it feels like engine stalls shortly - rpm on tach falls to 0, and rises up again after a second, and the bike is like jumping or jerking.

Thinking of problems with fuel pump, I disassembled it, washed the filter itself and filter grid on input.
Idle speed stabilized, now it's 1100-1150. But the whole situation is not much better. Any ideas - what else could cause this?

P.S. read the related threads, didn't find the solution

Welcome to the oRg. You have already done what I was going to suggest. Others with more knowledge will be along soon. Is the bike tuned? Have a fuel management like power commander or anything on it?

could be fuel pump screens clogged, gummy fuel lines/ or injectors, spark plugs could be toast and need replacing... that's my suggesstions to the .org throw up a pic of your bike while your waiting for more responses.

Hello again, my problem is still there (((.
I think, that the problem comes on 6 gear.
Also I have checked the crankshaft position sensor, like desсribed in manual, and it looks good.
