NC29 valve help

Coming to do my valves, got everything off down the actually checking the valve clearance. However, as per haynes I cannot work out what valves are my inlets and exhausts for whatever cylinder.

All that it says is 'EXL INL EXR EXL' or them sort of markings. I align T1 marking and it says to check cylinders 2 and 4 inlet valves

Where are they, I could do with a diagram showing me which valves are which and what cylinder they belong to...

Cheers

can you not work out by number of valves? i.e. 4 per cylinder and the in lets on the carb side exhausts at the front??
or are you pulling our legs you cheeky monkey?

Got to say having never done this before myself until last year I had the very same question, although I thought it was as you say the thing that threw me was the EX/IN printed on the cam heads. Hence I asked that very question.

No. That'll be the firing order.
Cylinders are 1234 from left to right as if you were sat on the bike, the inlets are at the rear/carb side of the engine - 2 inlets & 2 exhaust valves per cylinder.

Are you sure that you are up to this - it's all quite basic stuff.....

I appreciate your reply, however, it's the first 4 stroke i've ever worked with, every other bike i've had is a 2 stroke all being single cylinders.

Got to start somewhere haven't you and besides, this forum is here to help when unsure with something, is it not? Will check the clearances tommorow, thanks for the help all
