🏎️ High-Performance Yamaha Grizzly YFM600 YFM660 Carburetor for Improved Engine Efficiency Review

Worked great on my 2000 600 Grizzly. The front boot went immediately. The back shoe needed some stretching. Added a slightly longer screw for the hull clamp. Started right after installation. Would have given 5 stars if the boot had been fitted.

The guy who gave it to me had it new, one day the carb started leaking so he rebuilt the carb but he couldn't get it to work again so he had it in his yard. Before I devote too much time to it, I decided that a $35 carb would be worth the money to at least let me know if cycling was worth my time. . So yes, the carburetor fits. and no, it was no more difficult to
