I will be contacting Honda tomorrow to check on the XR650R intake valves, they are 37mm and can almost bet they will go right in.....probably like the camshaft.
That info is awesome!!!:yay: It's good to have someone actually doing the leg work AND sharing what they know. ThanksThat 37mm XR650R valve will work!
Stock 700XX valve measures:
Groove for locks are right were it needs to be too.
