I saw a pic of a big Kaw (1000, I think). The setup was the same as the GSes, the end lobe just dangles out there. Not sure why my bike is different. Hmmm.

Sorry I haven't posted pics of how I set up my indicator. Woke up with the stomach bug Saturday morning and have just started eating solid food today.
I'm really missing riding my bike and will have back together soon, with pics.Comment

A dial indicator extension works on the GS1000 2V and lets one rotate the enginine over & over without the cam contacting the dial indicator and screwing up the measurements. Since the 2V valve shims are all 29.5 mm it should work just fine on the GS650 etc. I mount the magnetic base on top of the cam cap with the V edge of the base wedged in front of the cap bolts.
No one responded to this thread but it appears others know the same info.

Andrews Cams Installation Instructions & How to Degree Cams Articles
Suzuki GS 750, 850 & 1000 Cam Installation Instructions
Note: If you have Andrews Cams and you read this whole thing they recommed visually setting 1/16" below the
cylinder head surface to achieve 108 timing.
Last time I was adjusting these cams in 2008 I tried this
visual method first and verified it was +/- 2 degrees. Pretty freakin close.

Apparently on the GS motor the norm for degreeing the camshafts is to have the exhaust cam number higher than the intake cam by about 2 degrees. An example would be Intake 106 degrees and exhaust 108 degrees.
On my motor the 650 specs from the manual have the exhaust lobe cente at 103 degrees and the intake at 106 degrees. Which is in reverse of the norm.
When I checked the lobe centre on the motor the reading I took tallied with what the manual stated.
Exhaust 103 degrees
Intake 108 degrees
Opinions are sought if there is a reason for these numbers being in reverse. My worry is that it is done this way to prevent the valves hitting the piston at TDC. The 650 has a very closed combustion chamber, with squish characteristics.
I dont want to reverse the numbers and have them at say exhaust 106 and intake at 104 and find I cause engine damage.
I have also read somewhere that the danger of valve and piston contact is likely to happen where lower numbers are employed. More risk at 104 than at 108 for instance. Anyone care to comment on this.
And I don't want to pull the head and do the clay thing to check the valve to piston clearance.
I need comments on why the numbers on the stock timing are in reverse from people more conversant than me.Last edited by Guest; 04-07-2010, 04:00 AM.Comment

Does Anyone Know the Answer to This
Are there any knowledgeable people out there on cams and timing to answer the question above?Comment

Well if this helps. I installed my cams by mistake 1 tooth out and didnt notice until i rotated the engine a couple times to check the exhaust center, which was less than 90 deg. There was no interference rotating by hand so no valves were hitting pistons. I cant say that if I ran it like that there wouldnt have been bent valves. So, you can be quite far out and not get interference. I just installed my new cams and set them at 105/107 just like I had set the old cams. no problems what soever.
Suzuki maybe set the cams on those centers for emmisions reasons or gas mileage or whatever, not so much maybe for best performance.Comment
