Interesting Valve Adjustment Clearances

[nejeff]

Did my first valve check on my daily rider 80" 850G. I have done several GS valve adjustments before but found these to be noteworthy.

3 out of 4 exhaust valves were out of spec. All 3 were LOOSE and between .11 and .14 mm

Only one intake was out of spec .11 mm, again LOOSE

This is the first time I have done a GS 8 valve adjustment and found any to be loose. I found it to be interesting and worth noting

Who did them last time?

Who did them last time?

Excellent question. The PO was an auto mechanic and he owned the bike for 3-4 years, owner before that was original owner and kept the bike up nicely from all accounts and apparently had it gone through at 40,000 with big bore kit. I can't substantiate any of this however as the PO was not able to find the receipts but he did have them at one time (or so he says). Hard to say if the PO ever did a valve adjustment. Bike had been well cared for is about all I really know and it took me about 30 minutes to put it on the road after sitting for two years. Has ran beautifully & reliably ever since

believe nothing the PO says especially when it comes to performance works unless they can prove it 100%.
everything is ported and polished/bored and stroked ect....
heard it my entire life and 99% of the time it was untrue..

Did you adjust them using the Suzuki cam positioning procedure or with the lobe pointing away from the bucket?

Ah, the dreaded Clymer's valve adjustment strikes again, perhaps.

I do have the genuine Suzuki service manual on it which I follow. This is write up that shows the actual positions the clearances were checked in. http://guglielmo.us/mc/valve_clearances.html

Like I said have done this several times but never seen anything like this

[tkent02]

Most likely the previous guy used the wrong spec and made them all too big.

At least the procedure is correct.
