My wife corrected me…I’ve had it 17 years…but I am just a weekend warrior, and it sat most of those years. I think it got most of its use before I got it

@huskihl @srcarr52 2100 crank…? Or would the stroker not work with the existing portage?

Doubt the timing will work.

Someone mentioned incorrect rings. That’s possible, as oem uses 1.5mm and Meteor uses 1.2mm. Should be able to see that through the exhaust port

I think I'd go ahead and pop that top end off and see what's going on in there.

Best
Question
Ever!!!

But yah David I agree with the guys that posted above that are a lot smarter than me. Honestly, if it were mine, I'd just plan a bottom end re-build. I could maybe locate a crank if needed.

Thanks dudes, that’s the plan, just wanted to get opinions while I was away today.

Crank brg is a few thou loose, there is some brg noise, and the crank case bearings are a lot newer than the rod crank bearing.

Finally pult the crank. Saw got smoked once years ago. Maybe that shortened the life. Crank brg has just barely perceivable end play.

When the rod end is blue like that it’s usually not a good sign. Just my opinion.

Yup, I reckon she got hot.

Just a weekend Warrior here…..

that play in the crank is “crank bearings… your pics of the big end could be a bad big end…. Or it could be wear due to the bad crank bearings..
If you were to take the crank and check if the was any play..then I’d replace the crank.. it be hard to check the big end with bad crank bearings in situ ..

but as for anyone ymmv.. and your the one that’s paying

Yep same problem I had, the flywheel movement test confirms it.
With the crank in your hand it was almost impossible to tell, just the slightest movement. But when connected to a piston in the machine it is noticeable. When running it sounds like a tractor, just like yours

I bought an aftermarket crank in which it was not machines correctly I believe. In the end I just shelled out for oem and have not have a problem.
