So far I love it! Seems to give my 250xc-w a little more power.

My stock YZ125 reed valve was signing off. I bought a set of these Boyeson reeds like I have done for the past 41 years. You can't go wrong with these. They just do their job well and don't cost a fortune. The stickers haven't changed in decades, and I like that. My bike runs as intended again. Easy to install, and worth the effort.

I think these are a little pricey but look great on the bike. Nice tight fit and now my vent lines are flexible . My old lines were faded and brittle.

Worked great on my sons Yamaha wr250. Only problem is I had to order a second roll. 1 roll is not even close to enough.

It seems to have improved the throttle response on the bike.
