Installation Note: If your saw is M-tronic it will be tuned in by the third or fourth cut after installation. If your saw is non M-tronic, we recommend re-tuning after installation.

Very pleased!

High quality craftsmanship! Noticed some increased throttle response, hard to say I notice a big difference in the wood due to so many variables but I am sure there is. Highly recommend as long as your expectations are reasonable!

I have about 50 hours on my 500 and I wish I got the bark box when I first got the saw. The bark box is exactly what the saw needs!
The screen on my mine "fell off" so it's extra loud !!!!!
