Moto Guzzi 1200 Sport/Norge/Breva Question

So, I've had my 1200S for about a year now, I love it don't get me wrong but there is one Mechanical draw back that I for the life of me can not figure out why it keeps happening.

For some reason every 2-4 thousand miles the Cylinder on the Throttle side of the bike eat's the Valve Cover gasket , In the 7K Mile's I've put on it I've gone through 3 Valve cover gaskets JUST ON THAT SIDE of the bike, Is there an issue with the 2V CARC Bikes that causes them to suck in the Valve cover gaskets or is this just a strange phenomenon.

I'm no expert, but I'd be looking at how the cover aligns and if there is any warping or uneven mating surfaces.

I have not had any problems with mine. 25,000 miles and 2 valve adjustments. I am ready for a third valve adjustment.

I had one tear when removing the cover for a valve adjustment, that was quite a while ago.

I check my valves at each oil change.

Are you using the thicker (still paper) gaskets? I believe that the 1100 gaskets are a little more robust than the stock 1200 gaskets, there is a thicker alternative out there somewhere anyway. Even if I can't remember what they are from, I bought them to replace those rubber gaskets (leaked) a few years ago and have not had a problem since.

Sounds like the area isn't venting properly, you say there is a vacuum that is sucking the gasket in?

Check out gaskets from MG cycle.
Also check out that the heads are venting properly. A clogged vent could over pressure/under pressure that area. Sucking the gasket in is bad...and unusual.

My 1200 Sport dribbled a couple drops of oil on the right side header at a stoplight....smell of burning oil got my attention

It had about 1,500 miles on it, and I'd just ridden it back from Ohio (where I traded an FJR1300 for it as a new leftover).
The valve cover gasket leaked that one time, after the dealer here fixed it - it never happened again.
