So after noticing (and per Glynn's techy advice) that I could use with some links off my chain, I did remove them...however now my mech (Shimano XTR) is not working when the clutch mechanics is engaged...goes to the top sprocket fine, but when it comes down it doesn't keep the tension and the chain gets loose and drops...strangely if I disengage the clutch, it's gets tension and all works fine, going up or down?
Does anyone know if it is the mech that is in fact f£&@@ or something I need to do further from the chain length reduction? If so, what do I need to do? Thanks in advance.

Is it definitely (the mech) set up right against the lug on the mech hanger?

Difficult to say without seeing it, are you saying the chains running off the small sprocket, if so the extra tension maybe effecting it so you may need to wind your lower adjustment in u till it stays on. Or try backing the barrel adjustment tension off a little.

If I don't engage the clutch machanism, the chain goes up and down the sprockets fine...and the much moves backwards and forwards if I move it with my hands...
If I engage the clutch, and run it from the lowest sprocket to the top one the mech goes fine, but on the way back down it loses the tension and the chain drops...but if I disengage the clutch again, it kind of jolts and gets tension again! Should have just kept it as it was ! Lol

G Zulu is saying is the mech itself sitting behind the little stopper part of the mech hanger, it has to be sat behind it or the mech and tension will be all over the place.
I expect it's right though as there would have been no reason for you to remove the mech from the hanger to remove a couple of links from the chain. Dos you it the chain back on running in that right direction? If I remember rightly it doesn't matter at all for 10 speed but some of the 11 speed set ups the chain has to be in the correct orientation as indicated by the markings on the chain.

Felt like a right idiot...so it needed was some adjustment on the b-screw...
Makes sense I guess, since by removing 2 links and making the chain shorter the mech will have moved forward when in tension to the new length.

Lol...keep it simple and stupid to me! Lol |

glad you've sorted it G. just a bit more advice if you want to take it from me  . dont forget to allow for the compression of the rear end. best to let out the air from the shock, completely compress the rear end to make sure theres not too much strain on the chain and rear mech |

Now you tell me...lol...makes sense. There is still some allowance on the mech even on the top sprocket but I'll do it in the morning before riding. |

Ah ah it will be ironic if you need to add two links back on.
Maybe you should have assessed if it was loose or not with the shock fully open and totally compressed.
They also suggest to do this on the largest sprocket however the chance of bottoming out the shock whilst climbing on the dustbin lid is pretty remote.

i just went with Glynn's advice...lol...lesson learnt! LOL
I've done what you guys said, put it on the largest sprocket and shock fully down and it looks like there is room. however the gears are not as nice as they were before.
I can't see myself having to buy a new chain...lol

So....update!
When the clutch is NOT engaged everything works fine (albeit with more chain slap)...but when I engaged the clutch sometimes the mech gets stuck when coming down from the top sprocket to the lowest. Sometimes it does it when I'm on the bike, sometimes on the stand...when this happens and as soon as I disengage the clutch lever, it snaps and stretches the chain.
So i think it's the derraileur that is actually cooked, even before I reduced the chain length (which probably wasn't needed!?). As anyone seen this before and has any smart ideas?

Adjust the clutch.

Yeah...ive done that...but i actually now think the issue was me reducing the chain...lol (thanks Glynn...lol) So i have now ordered a new chain, will try it again and adjust everything...if the mech still plays with the clutch on, then its defo the mech...if not, all it needed was a bit of adjustment in the first place. |

just picked this back up. this weekend iv mostly been in bed or at work.
lol gonzalo, that 'll teach you to listen to everything i say but it was yourself that first commented on being concerned about your slack chain. are you sure that the clutch jumping back into position when its switched to 'off' wasnt the cause of the problem in the first place? can you remove a cover so that you can watch what happens to the clutch when changing gear and operating the on/off. |

Sounds like your chain is too short..try adding a couple of links to it..should sort it out  |

lol another lesson to learn G. dont throw away the links that you've removed. you never know when you might need them |
