What did you do to your 2T today?

[Greaser Greg]

I was thinking more along the lines of an ashtray, but I like the trophy idea: First seized piston!
I guess if it was an old lawnmower I'd feel better about trying to use it. With a $500 crank beneath it, not so good.

Check to make sure the pump is giving an output.
Has it just nipped on one side?

Yes, just the right side. One piston was a bit tight as I swapped in an Oem for aftermarket after it was bored, so tried to make it work with a hone. Yes, the pump has been tested more than once so I doubt that was it. Will have another look at it though.

Looks to be oil on the pistons... Was this the shakedown run?

That's pb blaster try free them. Top were dry when opened.

yeah... aftermarket = different clearances due to material differences. sorry about that.. but don't do that again.

Cast pistons with TODAY's modern ethanol fuels need .002-.0022 piston to wall on new pistons at minimum,
They will run at .0025-.0027 with no issues.
Also I've always preached to scotch-brite off the breakin coatings at your piston measurement location so you don't boore it too big and have too much piston to wall clearance after the coating wears off. (approx. 1000 miles)

Hey thanks I'll check those numbers!

Not so much to as for my two-stroke: cleaned off a spot on a workbench, approximately parallel twin sized. Replaced a fluorescent light fixture, repaired another and replaced two tubes so my eyes will have a fighting chance. Time to yank the Elsie mill and get started on the tear down!

Lemme know when you're ready for machine work, I know a guy 

[85RZwade]

 :whistle:is he a bit North of you and a bit South of me?

[pdxjim]

Yes, and I just found out my LC cylinders are done and in the mail 🎉🎉🎉

And my wife gave me a DiD 520VT2 chain for my birthday! 🎉🎉🎉🎉

[85RZwade]

That lady is a good shopper! Chuck did your cylinders, right?

[Plasticman]

Picked up some new carb mounts with cross overs for the race bike.

Haha, well, she asked what I wanted, and I said "motorcycle parts" and she rolled her eyes and said "whatever ... get what you want".

... and no, Ed "EE" Erlenbach did this set of cylinders. 

[Greaser Greg]

Set the timing, cleaned the pilots, checked for air leaks, started it and ran the new (used) top end!

[pdxjim]

Dragged it out to the woods and rode it for a few hours.

Then washed it.
