I called them earlier, they don’t have it in stock. They are back ordered until May. I went ahead and ordered a wiseco 74mm 9.5:1 compression, just like stock. They show it for MY13 and up.

So the wiseco piston came in. To my surprise, it looks very different from stock. See pictures , , . This is a stock piston from a 2013 XT250 I saw on ebay, looks identical to the 2012 . Anyone got any ideas why the different design in the Wiseco piston. This is the 9.5:1 compression piston just like stock.

So it wont work. The MY 2013 and up have a bigger piston pin. So the Wiseco is going back. So I cleaned up the old Piston and it looks good to me, see pictures. Do you guys and gals thing I can still reuse this? I will add new piston rings. , , , , , , , ,

That Wiseco piston looks like the higher compression version to me. That big bump on top would take up a lot more space in the combustion chamber, raising the compression. If it fit at all. It may just be the wrong piston. The original piston does look ok, but I would go ahead and remove the rest of the carbon before reusing it, for three reasons. One, that carbon is thick enough to ever so slightly raise the compression, two, it could act like a glow plug, causing pre ignition, and three, not likely but it could still be hiding something.
The above is my opinion. Your mileage may vary. 1994/2001 custom built XT225 with a ton of aftermarket parts.

Quick update. Was able to locate an OEM piston. Last night, installed, new piston, rings, pin, retaining c-clips and gasket. Also found a OEM camshaft. Should have had the camshaft on Monday, but USPS strikes again. My package is delayed so no idea when I will get it. Ahh the camshaft is the only thing that I am missing now to put everything back together.

You're on track with your engine repair job, and that's gotta be encouraging. Hopefully the camshaft will be there soon and your XT250 will be up and running again. Looking forward to that final report, Organix. Fingers crossed that things go well for you..

Quick update. Bike is up an running. Have put 20 miles on it so far, runs much quieter and feels like it has more power. Now waiting for my registration paperwork so I can take this thing on the road. Just wanted to thank you all for helping me through this build

So back at it again. Decided to do a compression test on the rebuild. Used a harbor freight compression gauge. It reads about 100 psi when warmed up. Added a little oil and the compression stayed the same. Bike starts fine, idles and runs fine. I tested the gauge with an Air compressor to see if it is accurate and its about 5 to 8 psi off. I know the valves seal well, I did a quick test with water before installing the head, no leakage from either intake or exhaust. The compression test was done as per service manual. Not sure if it matters, but the bike wont start when cold without a choke, once warmed up it starts right away, no choke necessary, checked valves and they are within spec. I ordered a leak down tester, to have it a go. Any ideas ? Oh btw, I have put about 40 miles so far on the new build.

That's why they make chokes, to help start cold carbed machines. Great work!
