Is it possible to bore my 2013 Tc 250 out to a 270-280 cc by getting a bigger piston? If you can, who makes them and how much?

Hi everyone,
As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.
When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.
Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.
Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.
Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.
Thanks for your patience and support!
Over sized piston for a 2013 Tc 250

I am considering the same thing with my 2013 txc250.
It uses the same cylinder and piston as your 2013 tc250.
The only way I can think to make it happen is to get a 310 piston and cylinder and have the deck on the 310 cylinder shortened to match the 250 cylinder height.
It would require removal of over 5mm and I'm not sure it's feasible ywt. I'm researching the feasibility right now with a buddy's 310 parts that are disassembled.
This would bring the bore up to 82mm from 79mm. Effectively making the bike a 269cc from a 249cc
Not sure it's possible, but I think with the right machining to the 310 cylinder to shorten it enough it will work.

Sounds like a lot of $$$$ Matthew 525, but thanks for info.

Parts alone would be $650 plus machine work and gaskets. Easy 1000 bucks.
One other option is a sleeve, LA sleeves will do just about anything, probably $300 for the piston $250 for sleeve you would still be over $600.
Steel Sleeves aren't as good as a nikasil cylinder like the stock ones. It will degrade performance by a tiny bit but not a lot. Issue is end result is performance, so you kinda want the nikasil.

Again thanks Matthew 525. It is a great bike the way it is, but I decided I am going to sell it.

Just an update on this. After measuring all parts, the wrist pin on the 250 is much smaller diameter than the 310 wrist pin from the same year. It is not possible to use or modify parts from a 310 to use in the 250.
The cylinder has room to machine, but then we need a piston and Gasket still.
Looks like I'm staying stock
