Q1. My fuel gauge fluctuates and the lights dim if another item is used....eg
brake light on means others dim slightly.
Bad earth I guess, but what is the best way to solve this?
Q2. My gearbox slips in 2nd and 5th....quite common.
I've been given a fully recon box out of a 1200.
How easy is it to fit as apparently it goes "straight in".....

The transmission doesn't go "straight in".
The motor has to be removed from the bike and completely disassembled. Not a job for a "back-yard mechanic!"

whooa, a fully recon box? i doubt it very much! basically the crank cases hold the gear train in possition, it is a major engine rebuild and i mean the full monty to change a gear train. unless you are a skilled mechanic with all the right tools then its not worth getting involved especially when you find your "new" gear train is not what you were told. yes the 11 and 12 gear trains are the same and will drop straight in but if i were you i would be tempted to look at the clutch pack first. much easier to deal with and sounds more probable as it is impossible for the gears to slip. you can get a complete running 12 engine from the bike breakers for about 400 to 450 quid, with a money back garrantee. good luck.

You've got a bad earth, check the frame to wiring loom connection for corrosion. The gearbox swap is relatively simple with a haynes or clymer manual, split the crankcases lift out the old gear cluster, fit the new one and rebuild, new selector forks or the ones out of the 1200 box would be a good idea too.
Best bet is buy the manual and see if you think you are up to it.

Get a multimeter and set it on the lowest dc volt setting. put the positive probe on some metal part of the dash and put the negative probe on the negative terminal of the battery. Turn the key on. If your ground is good up front then you'll read 0 volts (or maybe a tenth), so it'll likely be a positive lead that is faulty. If you read something more than a tenth then it is likely a bad ground. This could be anything from a bad plug to a really rusty head bearing.

First you are right sounds like a bad earth to me, and if you havnt done one of these boxes before get somone with experience to assist you as there are a few pitfalls in the reassembly
