So I followed this post and have got to the point where I have the cams exposed with the head cover off, and the bottom side of the cam chain (right hand side cover), spark plugs are out but I cant move the back wheel to get the cams turning to get the bike in to TDC.
Any ideas how I can get the engine to move into TDC position?
So far I have tried putting it in higher gear (2nd & 3rd) and moving the back wheel but literally no movement.
I know the engine is not seized as I started the engine before removing anything off the bike, could it be the gearbox is seized, if so how would I know.
Is there anything obvious I could be missing?

seems odd but maybe try 6th gear? also put it in neutral and see if you can turn the wheel-maybe your rear brake is seized/binding (?)

The rear wheel turn fine in neutral but when in gear it won't move.

Is there a way of rotating the crank without the rear wheel?

Hi there!

If someone is interested, the cam chain was indeed stretched out by half a link's distance. I installed a new one and the marks did align much better. So I highly recommend that anyone attempting this orders a new cam chain straight away...so you don't have to wait for 2 or more weeks for it to arrive...

Sam: Strange that your engine doesn't move. Mine moved fairly easily from the rear wheel when having it on 6th gear. Though it was much more convenient and easy to rotate the engine using the front sprocket nut. Just put a proper socket and a long enough tool to it and you should have much more force than from the rear wheel. That is of course, if the sprocket won't come off...

like Coriolis said, from the front sproket nut...but Iíll admit Iím really puzzled. Just to recap:

the rear wheel turns fine in neutral, the engine was running before you took things apart, the plugs are out, but you canít turn the engine in 6th gear from the back wheel? Is there a dropped tool jamming something? Seems to me the engine should turn fairly easily in 6th with no spark plugs.

Worked on the bike last night, and with a substantial amount of effort rocking the bike back and forward off the stand I managed to get the engine moving, it seemed as if the starter motor or gearbox is resisting it as it sounds like I'm trying to bump start it but its all good now....Thanks for your help so far and hopefully the rest goes smoothly.

I solved it!!!!

Just thought I would let everyone know what happened and how I fixed it.

It's all my fault, so what i have learnt is follow the advice of above and check and double check everything before you do something not after!!!

So in trying initially to get the engine to TDC in 1st gear (should have been 6th) it wouldn't rotate so I loosened the cam chain to allow the crank to turn... I stupidly assumed there was too much tension and that was stopping the cams rotating.... the crankshaft spun and cams didnt....nightmare... that put the timing out. Once I realised and tensioned the chain again the valves were fouling and not allowing the cams to turn. So it meant taking Cams off and realigning it all to TDC.... a very dark art and certainly worth working with a friend to get sorted, one of you watching the timing and one rotating the wheel/crank. You need to take the cams off align them put them back together then rotate the engine 3-4 times, check marks again, it aligned do another few rotations of the engine, if its all still lined up you are sorted. If not take cams off, move one tooth then reassemble and repeat until you get it all aligned. Then you can start again from TDC checking valves etc.

All that and my valves are all within tolerance .... what a ball ache.

I hope this helps anyone with fixing a very stupid problem.
