valve timeing.

my bike has gotten very clicky recently so im guessing the valves need doing

any idea how long it would take and much it would cost to get them done?


of is it easy to do your self??

thanks

Not sure clicky would be valve gaps, I'd be more suspect of cam chain tensioners.

To checking the valve shim gaps is pretty straight forward, however you'll need to remove the cams to change them, best left to someone who knows what they are doing.

To check the valve gaps.

Remove the tank (you don't have to but it's easier),

Remove the Air box,

Remove the carbs/throttle body assembly (you can leave it attached to the control cables if you like just either bungy it out the way or lay something over the frame rail and lay it across that).

Take the plugs out,

on the left-hand side of the engine (sitting on the bike), remove the centre plug from the rotor housing, this should reveal a 17mm bolt head on the end of the crank.

Remove the plug above this on the top of the housing (viewing window).

Remove the rocker cover(s)*, take care not to let anything fall into the engine from above; otherwise you'll be stripping the whole thing down.

Using a socket rotate the 17mm bolt head clockwise, measure the gap between the valve bucket and cam when the lobes are pointing away for the bucket.

Make a note of all the measurements, don't forget to do the inlet and exhaust, put the rocker cover back and do the other cylinder.

Take your measurement ands compare with the given range in the manual.

I n true Haynes style re-fit in reverse of above.

Why's that?

Also I managed to do it without removing the tank, airbox or throttle boddies.

there's no need to expose the internals whilst working on the other cyclinder.

Righto, just wondered if there was a technical reason
