Title: Kerry's vs Haynes is one more right than the other doing valve clearance check?
Post by: dread_au on April 19, 2012, 06:32:08 PM
I have just done my clearence check using both methods these were my results. 2005 gs500f 60 000kms.

valve  hayne/kerry

left exhaust 0.07/0.04

left intake 0.06/0.07

right exhaust 0.06/0.04

right intake 0.05/0.05

It did this a few time with each method using the same tools and got these results. As you can see they are either ok  or the exahaust ones need to be changed. Any advice would be appreciated before I go changing shims. Thanks

Does the Haynes manual do the checks using the R/T timing mark on the crank and the notches in the cam aligned with the cylinder head? If so, that is the way the Suzuki factory service manual says to do it so I would trust that method.

Got the same kind of results first time I checked GS valves rechecked by the book and have followed the book since, set on marks like Suzuki shop manual, Haynes, and Clymers says.  It's easier to do it the right way.

However, I got tighter exhaust readings same as you did indicating I needed a smaller shim so if I or you had put in smaller exhaust shims no harm would have been done.  In over 170k GS miles I've discovered setting the exhaust valves wider than the GS specs will increase exhaust valve life by providing greater cooling seat time.  I set intake at standard .03-.08mm but set exhaust valves at wider .08-.13mm.

It seems the buckets are tighter at the exhaust than the inlet. I managed to get one around but could not get the other around so I have left it for now. I replaced the one that I could get the shim out. Spent 2 days trying to get the buckets to spin lol. Thanks for the help everyone.
