Exhaust valves rm250

Just wondered how much of the entire pv setup is interchangeable between the 98 and 99? Just brought a 99 barrel for my project 98 rm, that's fitted with a 99 motor. The barrel I brought is bare though so all I have is everything from my 98 barrel........if that makes sense lol

hey im no expert but if yours is a 99 cylinder it doesnt look like much would fit from your 98 p/v

my 98 has a t/v/w model cylinder. theres 3 different p/v set ups for this cylinder

theres also a x/y model cylinder which share the same p/v set up except the y model has a solenoid off the valve housing. heres the site ive been using hope it helps


good luck with your RM
