The valve clearances are easy to do - you just need to be careful with the whole process and be prepared for the bike to be out of action while you wait for new shims. The order in which each cylinder gets to TDC is 1, 2, 4 then 3. It's good practice to drop a bit of oil over the cam lobes as you turn the engine over. You just open it up, measure the clearances, pop out the old shims and read their values, decide the ones you need, then order or go out and get them. The bike will be out of action for as long as that takes. To take out the shims I used a horrible tool called a Laser 6519, and a small hand-held spike and a retractable magnet. Don't bother with the 6519 - it's ridiculously tricky. Use something else, maybe like this:

Don't forget to have a set of feeler gauges ready.
Thankfully I'm off work for 10 days now so it's a good time to do some extensive maintenance :)
I'll have a watch of the video and look through the Haynes manual to order some shims, thanks again :)
