Any UK users with this problem?

My 52 plate R6 started skipping through 2nd and now it's really bad. Probably hiccups about 10 times throughout the rev range.

I've been riding it for months like this, and it hasn't done any other damage (from what I can tell).

I have a spare 99 engine, and a spare 04 engine -- both gearboxes are fine.

What would you do in my position?

Fit the 99 box, or the 04 box?

Is it easy enough to fit the 04 box, and is it gennerally a lot better and smoother?

Every garage I speak to refuses to quote a price for doing the swap. How much roughly would it be?

What actually "goes" -- what will need replacing? The entire box, or just one cog, or what?

Anyone live near London who would fix this for payment?

Took both my 02 R6 and the 04 R6 to my mates garage ready for the change. Both bikes were complete and ridable.

The 02 R6:





The 02 R6 and the donor 04 R6:



The 04 engine out:



Getting ready to remove the 04 gearbox:



The 02 engine stripped:



The problem:



Had a few snags but to strip both bikes, drop both engines, and remove both gearboxes in an evening is pretty impressive, I think!

The problem!



No gearbox in the 04 engine...



Engine going back in...



Nearly done...



Testing everything out...



All done. ;)

...and then to test the gearbox out I went through the box on the paddock stand (the clocks showed 196mph bouncing off the limiter in 6th).

Here's a video...

I noticed my clutch slipping alittle the other day. it doesnt seem to be in one said gear. when you throttle up it seems to slip alittle then takes off. now how do I know if I have this problem or just needs to change the clutch plates? no hard shifts, no clunks, no jumping out of gear.
I have a 00 r6 with 8k miles with most of them have been track days.
