Crankcase torque specs for trail cat?

10 mm and 12 mm bolts. Anyone know the torque specs and pattern? I was looking at similar sleds, buy the patterns and bolts sizes were different.

This is 340 Spirit Engine.

I think I figured out the torque part of it. I wasn't measuring bolt, rater the head. I have 6mm and 7.5mm bolts. I torqued to 7 & 16 ft lbs.

I tried to follow a logical torque pattern, or so I think.

Torque pattern is do the large bolts first, then do the smaller ones starting at the center and work to the outsides in a crossover pattern, then redo the large ones.

Those are 8mm bolts, not 7.5mm. Run them up to 18-20 ft.lbs.
