Depends what you call reasonable ... if Worthing's not too far south then go to Alf's Motorcycles, great guys who know their stuff! http://www.alfsmotorcycles.co.uk

why not just go for a chain with a soft link, break the original, join the new one, feed it through, take off the old one join the new one.
lot easier than messing about with internals

I did my valve clearences at 42000km but did not see any recomendations to change the cam chain, which i thought was odd. I did notice a drop in power but i put this down to the valves not opening as far. Bike has 57000km on it now, motor still fairly quiet no cam chain rattle at all so i figured i would change the chain at 84000km just to be on the safe side.

If you can manage to get the cams in and out, you can manage to change a (one piece) cam chain... It's easy. Plus you can check the oil pumps are in spec while you're at it....

I checked my valve clearance today (all inlet's are out of range <0,05).

I wanted to check the chain but i don't know the original length of the chain?

My camsprockets are a bit off, so that made my worried! so i want to check!

don't chance it ,if the timings off the chain must be worn , you now have to take the cams out so while its in bits fit a new chain and check the oil pumps ,, let us know how you go on

Is it a possebilty that the chain haves been off since i bought it and that it just need some readjustments?
i'm going to get new vavle plates tomorrow and put it back to gether and try to get the timing correct

cam chain is adjusted by the cam chain tensioner,, if its at the end of its travel ,,new chain ,if marks don't line up , new chain ,,can you see were this is going ? if in doubt new chain

problem is cash at the moment! just had to pay a 480 euro speeding ticket!

do you need to replace chain and sprockets?

A tip from the Dutch TDM/TRX club about the timing chain and tensioner:

Remove the spring of the tensioner, put in a screwdriver, rev the bike to 2-3000 rpm and push hard on the screwdriver. this will give a extra click on the tensioner and will remove the rattle.

I wouldn't recommend that, the spring exerts a certain ammount of pressure for a reason. You could end up, snapping your chain, and the timing still won't be in!!

I can't see a measurement for cam chain length in my Yammy book, as I said B4 if the marks don't line up perfect, and appear retarded

, then it's new chain/sprockets time..

Can I suggest a radical reduction in your TRX's gearing? Might help with the fines, plus it should improve your wheelies.

For a Wheely you lose your license! and will cost you bigtime!
i did 120 in a 60 zone, lost my license for 5 days.

Just picked up the valve shims, going to put them in after diner.
