NC29 "grab" after 10000RPM. Does it common ?

[PARUS]

Hi,

I was on track last sunday. And couple of rider said that my 400ccm "grab" after 9000-10000PRM. There is not too much 400ccm and difficult to compare. Does it common for all NC29 ?

I have KENSO jet kit setup and TYGA pipe but with "stub" for road used. Maybe need to play with needles. What do you think ?

1) never let other people ride your bike! they fuck it up, not all can pay for it.
2) yes could be the jetting not quite smooth.

1) it's your bike let who the hell you want ride it.
2) if you are just swapping end cans yes it could be tour jetting, however without more info like does it do it in all gears and what exactly you mean by grabbing It could be anything from badly balanced carbs to a knackered gearbox.

Sorry, this is my bad explanation. Bike really ride well as for me but after 10000RPM there is a "leap" in power of the bike. I suggest this is due to needles, because needle responsible of the power between 2 - 8000 RPM. But just like to check is this same for other NC29.

LP: Yes, I'm agree, but we just test each other bikes - e.g. I'm run on CBR600RR\SUZUKI SV400. Just to test all other bikes.
