Absolutely nothing for a long while. I guess everyone will switch to ninja 400 instead of investing in a big bore kit......

I think I am going to have some +3 mm pistons made. Available for purchase with gaskets (head/base), head bolts and exhaust gasket. I am trying to source a couple used cylinders now so I can have them bored/plated to size on the shelf. If I cant, you guys will be responsible for having your cylinder bore/plated to size with the new piston. Plus 3mm makes it a 399cc. Gasket configuration will be 13.0:1 compression for street guys on stock cams and pump fuel. Stock is 12.6:1. It will also require my intermediate sized injector. For guys that have my kit items already thinner gaskets can be supplied for 14.0:1 compression install. Let me know what you think and if you have any interest in one.

Any update on piston kits please

Chad hasn’t posted in over a year, and he was getting hardware off his shelf. I don’t think we’ll be seeing any more KTM support from him.

Maybe. New gen is around the corner and the motor seems to be the same so to me, it wouldn't make sense to drop support if you're regarded as a 390 god
