Advice on where to start..........

[playerone]

Bike broke down at weekend, half hour after passing mot and getting taxed for the year it did restart after about 40 mins but only for a few seconds and sounded like a couple of full socket sets with a few spanners rattling around in a cement mixer...........
It already has mcct's fitted by a resident guru so I'm 99.99999999% sure I can rule that out but could do with some advice/suggestions as to what else it could be???
Fortunately I'll have a helping hand in this task with someone who actually knows one end of a spanner from the other

Well, my TRX did the same when the mechanic didn't reset the front camchain tensioner and scrapped the head. Think you need to start getting it stripped really Neil

the way it sounded I'd already put money on it being a new engine job, the mcct's were fitted a couple of years ago and it's done a few miles in that time and there was no indication that was the problem, I know the sound of cam chain slap only too well from a previous bike
But your probably right, only way to find out for certain is just to dive and and get it stripped.....bugger.......

Doesn't sound good - Have either of the two MCCTs unwound?

All you can do is to start with the easy stuff and work your way in.
Take off the clutch cover and you can check the clutch, oil pump, rear cam chain and water pump.
Then pull the alternator off and make sure that it's nice and tight on the crank shaft end. And once the alternator is off you can see the front cam chain.
Next, rads off to give you access, and pull both heads.
You should have found something by then, if not its mains, big ends or gearbox.
Have fun

You can always start by just pulling the valve covers to see if the valve lashes have opened up.

This will tell you if the valves are bent quick and easy.
