I'll be doing over 7k rpm and when I open it up it just dies for about a second before picking up again, like I've actually switched the ignition off, which makes overtaking dangerous.
I've had the tank up and checked the fuel lines are in good condition, not kinked or blocked. I've changed the plugs and had it serviced but it makes no difference. The battery is in good condition, TPS is fine (jumping to 5k when tested) so I reckon the next stage is to check the carbs.
I've not checked the rubbers or stripped the carbs down because in my experience with car carbs, any leaking inlet rubbers or sticking needles affect the tickover/low revs more than high revs. Is that wrong though?
The next thing I was going to do is balance the carbs, but before I start I just wanted to know if there's anything obvious I've missed.
What do you think?
It could be carburetor nozzles.
I've had the same symptoms after installing some aftermarket (wider) nozzles because I though I was gonna get some additional power (we did rejetting), instead I lost power and it would halt briefly at around 9k rpm, as if you've cut fuel supply briefly (for a second or so).
Returned stock nozzles and everything ok again.
If you already have stock nozzles, then maybe it's worth checking them out, maybe they need cleaning or something...
Good luck.
