Hmmm. Ditto to above on mine??
I definitely don't have shoulder there to stop my valves. I have some cast blocks on the housing but they do not touch before the gasket is hit with the valve. Different in '13?? Production tolerances??
The way I see it on mine, there is nothing there to seal the extra gasket material except the valve when it touches anyway unless an "unsquished" gasket can be considered a seal.
So is this seal needed only when the valve is open??
Never thought about the valves too much in the Suzukis. Added weight but the cable stepper motor had it's advantages. Besides clean and trouble free the added ability to open only partially added some torque to the laydown engine. Maybe allowed taller exhaust ports too for top end power.
Don't the Etecs have ex valve progression control too. Maybe next gen of CFI lol.
Any how, paper and metal smashing it, lol, is not a long term thing. So,,,
I pulled my easy side out last night. I'm trying 30 thou aluminum here first (easier to work with and only have 40 thou stainless). I'll check it in a couple of rides.
IMO if this area had a metal gasket the pic above would not happen. I've seen it 4 times now but not as bad.
