Best gasket set
This top end gasket set works perfectly. It came with everything I needed to rebuild the top end in my 87' Yamaha Warrior 350. I highly recommend it.

Hot Cams Camshaft (Stage 2)
Nathan in UT
Great power and tourque
The kit itself is amazing. The instructions are clear about what to do and the break in procedures, and overall the kit really woke the quad up. A bit overhyped in the comments (I have a lexx slip-on and am also jetted for altitude) and just wasn't what I expected but still amazing!
