Here we have a set of 4 valve for the 2010-2012 - TE/TC/TX 250/310 X-Lite in stainless steel
We have had a batch of these valves made here in the UK
Standard valve spring pressure is 200lb per inch and we have evaluated these in 2024-2025 and found that the springs work well.
We recommend changing the exhaust valve springs as these are prone to fail due to heat cycling(the exhaust side is exposed to more heat than the inlet) we have seen many with broken small spring on the exhaust side.
The red top 2012-2014 TE250/310 also has 200lb per inch spring pressure which use stainless steel valve
