Sorry to revive this conversation, but i need some clarity.
I have the RT position on the crank. (check ptoho).

The left intake points up, the right intake points backwards. (check photo)
(http://i1206.photobucket.com/albums/bb447/dfranc/IMG00118-20120207-1542.jpg)
At this point the manual says to check clearances. Do i check clearances of the first three valves in exactly the position they are with crank on RT? Or, do i check the one pointing up, and rotate the crank until the others point up, like what Kerry's valve video shows. (I'm assuming thats what Kerry does because his video only shows him doing the first one - right intake).
Thanks
I assumed you check them as they are...
Thought so too. Nobody really explained why Kerri does it the way he does and not just follow the manual (i'm sure he has a good reason).
The suzuki way is to check all 3 valves with the RT marks in thet specific position. The left exhaust has to be checked in the other position as the manual says.
The Kerry's method is to check the clearance with each pointing up.
The final conclusion is that the difference is not relevant.
Note: my pulse generator. Is different than yours so I can't tell for sure the position in your picture is the one shown in your manual...
I think that Kerry does that way because is the general rule of thumb to check the clearanceals in simple engines like the GS. And the simplest way too btw...

There are notches on the right ends of the cam shafts and with the rotor on the R-T mark if the notches point inwards towards each other you set both intakes and the right exhaust valves. Turn tne crank 360 degrees a full turn to the same R-T mark and the notches will point outwards on the cams and you set the left exhaust valve. The crank take 2 turns to one turn of the cams on a 4 stroke engine.
Rev: corrected crank/cam turns statement.
Good deal. What i'll do is try both methods and report my findings. It'll be a little while as my feeler gauges haven't arrived yet :mad:
Thanks for the input.

Just a little nit pick here: The cams turn 1/2 turn to one turn of the crank. Not that that changes the procedure, just hope to resolve some confusion.

You are right Paulcet, my error corrected in post above, ty.
Checked valve clearances today. These are the results.
Left Intake : 0.04 < # < 0.05 Right Intake : 0.03 < # < 0.04
Left Exhaust : 0.06 < # < 0.07 Right Exhaust : 0.06 < # < 0.07
The Right intake valve clearance is close (betwwen 0.03mm and 0.04mm), do i call it good or change the shim? (shim is 260)
Thanks
I'd go with those as is. If it was an exhaust valve that was that close to the min clearance I'd put in a smaller shim. Exhaust valves that are run on the tight side begin receeding into the seats after 30-40k miles requiring frequent shim changes after that. Intake clearances don't change much if any, at least that's been my experience with over 80k miles on a 97 and 92k miles and counting on a 02 GS. I set my exhaust valves to .003-.005" (.08-.13 mm) now.

Thanks gsJack. I'll button her up tomorrow and see how she runs.
