Boyesen Rad Valve
Dustin in OH
Good reeds for the money
I paired this with the new Lectron Pro Series 38mm with Xcelerator rod. Seems to run pretty well with them. I decided to go with the rad valve because i wasnt sure how old my stock reeds were in my 250X but it was an easy install. I ended up leaning my metering rod 1 full turn lean and that seems to be the sweet spot. Plenty of power and im able to lug and roll into the throttle with no issues, Came with a new gasket and new bolts. The boot was a tight fit with the lectron but just a little bit a wiggling and it popped right in and is super secure.
