That says that the Wiesco MLS head gasket on your bike leaked. I can't explain why but I do not believe that MLS gaskets are a bad in general.

Ed what it means is that it has nothing to do with the surface preparation achieved by the machine shop. There are only two alternative s left, either the MLS is garbage or the MLS cant be installed by a reasonably competent pair of bimbos.
Who are these guys?

It's the sidekick bimbo that helped with the oil spitting 1166 big bore job.
That gasket was a POS!

Geez, I got into this thread too deeply before it deteriorated so much. I began to wish I hadn't started with it.
IMO, if you can't accurately measure the trueness of ALL your mating surfaces yourself when doing a top end rebuild, go with composite head gaskets. They are far more forgiving of warppage, distortion and damaged or poorly cleaned surfaces.
If you are leaning towards using MLS head gaskets, you need to be aware that your oil supply passages won't have a rubber sealing ring around them. The gasket alone will need to do the sealing task. Also, the cam chain tunnel o ring will be be causing greater resistance to compression due to the MLS gasket completely covering the o ring sealing area.
The OEM and Vesrah composites don't cover the o ring area, so the o ring doesn't get exposed to as much sealing pressure as it will when a MLS gasket is fitted.
I'm not sure whether this is good or bad. Some will say that the o ring may cause less sealing pressure around the #2 & #3 cylinder areas, which may be bad. Fortunately, there is plenty of room for the o ring to expand in the machined groove on the 850, so I'm going to give it a try. I doubt that any oil will find it's way past that o ring/gasket combination.
My surfaces are now quite true, so it will be a good test.

The $64 question "What is good enough to use MLS?
My head was surfaces and the cylinder tested true. What that meass I dont know which is what I was trying to figure out. I tend to agree with your assessment, as it makes sense and I had it driven home by the experience.
MLS gaskest are for exceptional surfaces. An Ed, while the Suzuki OEM gaskets are muti-layered, they are not MLS. MLS are stainless.

Further on my leaking head gasket. Removed head hoping to find an obvious reason for the problem, no such luck! The head and cylinder surfaces were checked by the shop when they did the bore and supplied the gasket etc. The machine shop indicated that they will talk to wiseco and try to work something out on a replacement. Which I appreciate,but I am leery of using the same product again. Is there any agreement amongst the more experienced rebuilders as to what the most reliable way to go is? Before starting the rebuild the motor had 40k miles, stock gaskets ,never leaked. Someone on the forum said they used a stock 1150 gasket and trimmed to fit. What is involved in doing this?
Again appreciate any input , Thanks

First of all, WISECO doesn't make gaskets! They only sell the ones they get from COMETIC! I have had problems getting Cometic multi layer gaskets to seal also. I put 2 coats of Gasgacinch on the head, the block & both sides of the gasket, letting each coat dry before re-coating. With this type of prep, I have NO leaks. Thanks for the reminder Jim, I forgot I still have your gaskets! Do you want them trimmed for an 1166 or a 1229? Or maybe, one of each?! Ray.

WELP, I installed my wiseco head gasket (made by cometic) on my rebuild with just a little sealer around the oil passage areas and no problems at all. Did a couple of retorques since I first fired it up.
BTW, I have an inaccurate torque wrench, so I made sure to give it more than enough.
