great buy

Awsome and instant power, when u compare this valve to the stock veed cage it just looks like it has better flow. then when u put it on.. instant power. need to lean out the jets 1-3 sizes but other then that it fit perfect for my 01 cr250, all aluminium means it replaces that cheezy plastic stock reed cage which is prone to cracking and sucking in sand and dirt and killing your engine. great but looks great and performs better. Fast shipping and great service on this hard to find part for my bike thanks denniskirk and boyesen

AMAZED AT QUALITY

This is how parts should be made! This product is better than I could have expected. Now if only stock products were made with this quality. Solid piece of gear that fits perfect. Dual reeds was an added plus also. This is wayyyyy better then the multi piece stock part. I would not only recommend this product and company but its the only place I will buy from because of the bad a** quality and price of products! THANKS DINNIS KIRK!!!!!!!

Cant be beat

The product installed great and increased my bottom end tremendously. Every bike I ever owned I did this up grade and always with the same great results.

Pricey...

It is a pricey product but if you are looking for that extra little bit of performance get it. Just don't forget to go 1-2 main jet sizes smaller!
