Sourcing Top End Rebuild Kit For 2007 Te250

Hello,

I recently noticed a loss of compression so I dug into the top end and started inspecting.
Cylinder walls are scored, piston needs replaced. Need a gasket kit obviously too.

I tried looking on wiseco but the piston kits there aren't available anymore. Where can I go to source top end rebuild kits for this bike?

ProX makes pistons for these bikes as do Athena and Wossner.

Here is the link for ProX's parts number list. They seem to make everything you need except the gaskets.

Athena Gaskets are here:

Athena Pistons are here:

That's about it for aftermarket as far as I've been able to find.

Thanks for the input! I looked through them all. ProX is a pain to source, everything seems to be out of stock that I find. Wossner had stock but I was looking at my cylinder and found out that it has to be bored and replated.

I just ordered the athena 300cc big bore kit since I needed a cylinder too. Really hoping this bike is worth dropping 1k into

I have not had success in finding a piston kit for my '13 TE310R. In searching the Athena site linked above, no pistons are found. The big bike parts sites I search , appear to have few internal engine parts available for this bike. What engine parts sources do you 310 riders use?
