nope, just be careful with the rubber gasket on the cam cover. It is fairly strong but can be damaged by strong hands!

Thanks, that was some very comprehensive and informative posts guys! So the exhaust I think is fine as I only have a 0.2mm feeler so can't measure the exact 0.21mm minimum clearance, however 0.2mm went easily with very low drag and 0.25mm wouldn't fit so I'd say exhaust are around the 2.1mm tolerance.


Intake on the other hand, most of them measure 0.004" which is 0.1016mm so that should be fine. Unfortunately one of the intake valves measured 0.003" which is 0.0762mm so that probably does need swapping by the sound of it!


I am not entirely surprised that the clearances would get tighter as you say Major Rant, surely the head would wear faster than the oiled cam/bucket assembly? I think that I will have to stick to the manual on this one and pop in some new shims to be on the safe side!

sorry, i meant 'what problem are you suggesting is caused by the cct?' I know what it does but my query was about valve clearances and whether the cam chain should be tight against the upper guide (found between the intake/exhaust sprockets on the head). Not sure what you are suggesting is caused by cct :S

Hi all, Just check my valve clearances (its bloody freezing out!) and exhaust are all at 0.2mm whilst intake varies from 0.076-0.1mm. From memory Intake should be 0.11-0.2mm and exhaust 0.21-0.3mm, so what affect will my clearances have if left unchanged (it's a real ballache)?


On a side note, whilst the cam cover was off I noticed that the cam chain is continuously held tight against the chain guide on the top of the engine (between intake and exhaust sprockets), is this normal?


Thanks!

I cut down a modern FZ6 touring screen for my FZS and its a marvel when doing long mileage!

the bbq high temp stuff is very matt so wouldn't use on covers etc

sounds like you need to balance carbs, check spark on 2 cold cylinders and try resetting cam chain tensioner. It can come on suddenly, at least it did on mine, and then disappear just as fast. Apart from ticking it sounds like a very rough idle, does it pickup easy and smooth when you rev it or does it bog down at all?

not the cam chain as it was that quieting down that allowed me to hear the new tapping. exhaust nuts were torqued down only a week ago so thats sealed nice.

no idea, its a replacement motor i put in. Estimated at around 35-40K miles on it but don't know history. Will have them checked at next service but do you get any tapping noises with valve clearance problems?

Hi Mouse, did you find which spring that referred to?

Thanks Darrsi but I don't clutchless shift often and NEVER from 1st to 2nd as it is far to big a ratio step so isnt very smooth.


How much did it cost you out of interest to get that work done? (its an engine out and cases-split job yes?)

Major Rant, do you mean adjust the linkage/selector shaft (with the dot on) or the height or the gear lever relative to foot peg?


Thanks guys!
