hey, I am getting new valve and valve seats put in my 2017 kx250f head with a 5 angle radius valve seat job the bike has pro circuit cams and valve Springs and I think it has a high compression piston in it and it is almost impossible to find titanium valves for a 2017 kx250f what are the best valves I can get I was looking at pro circuit valves but they are flat faced and i heard that they are a bit heavier then like dished valves anybody know really good 1 piece titanium dished valves or should I ignore the weight and get pro circuit valves to match the cams and spring and the rest of the pro circuit motor?

You could run stainless valves and I’d argue you wouldn’t notice much difference if any at all. If you’ve already got stiffer valve springs your half way there anyway. Did you try Rocky Mountain for oem Ti valves?

I want titanium valves because of the weight difference and steel takes away from the rpm and more wear on the seats but no I haven’t tried Rocky Mountain I will look now

I’d go oem if you can’t find your preference of aftermarket.

Stainless valves are great. Have them in both of mine and i dont notice any power issues. Just make sure you get matching springs.

There fine for stock trail bikes and stuff but my bike is completely built and I don’t like the weight for racing
