going to need a bit more information!

what are the symptoms? whats it doing when it hits 10k?

[eastanglianbiker]

is it restricted?

Has it got a rev limiter? Where's the red line?

[Guest]

the red line is at 13-15k

the bike bogs at 10k, and will max at 120mph,

asked former owner who didnt think it was restricted but was unsure, and i checked all the paperwork but couldnt see any certs or that?

[Stu]

Time to open it up and look I would say

[Boothy]

Sounds very restricted

I think a thundercat at 10k would be putting out a lot more than 33bhp! Sounds like fuel starvation to me, or a problem with low charge. Does it rev higher in first gear? Less load, means it will rev higher but use less petrol, ie-will rev less and less high as you go up through the gears, as it will use more fuel to get the same revs in a higher gear. If it's the same exact limit in each gear, I would look a spark issue-coil packs, battery charge etc.
