M10x1.0 helicoil is the best option. They really work well for that small thread pitch and the outer diameter of the repair coil is less than the sealing crush washer of the decomp valve.

I wish there was some way to break the glue bond so you could reglue them. I have 2-3 tanks that leak fuel.

The problem with welding on these is that they are originally glued together. So wherever you stop the weld on the seam the glue is probably going to be comprised for a little while from the heat.

181/281/288/285/394/395/298/1100/2100/2101 all use the same clutch drum and can even use the same clutch.

The rubber wiper goes against steel ring cup.

I went looking and they did have the pins over the intake port.

A copy of the last piston design in this series would be nice. I think it had the locating pins more off to the side like the 394 though.

No. It was a different muffler.

I would pick up some. My 550 gained .3hp with a larger muffler mod.

Odd, usually people swap 288 pistons into 066's to get wider ports.

I've made more from a 572 than most get from a 372. That was with a gutted muffler but breathing through the stock spart screen.

I'm not taking any porting work, my schedule is full.

Those have 3 rollers inside on ramps that clamp down on the stud, they will dent the threads. They only work well when there is an unthreaded section that you can clamp it on. It's best to use a couple of nuts jammed together.

Seems like they never do. I just welded 3 cylinders that had failed inserts.

562 MK1's can be pretty peppy but they do like to eat crank bearings.
