The spacer looks good and bolts right up perfectly. They dont tell you that you will have to do some serious airbox modification or eliminate it all together. 10 minutes after I removed the spacer from the package it was in the trash!
Bought this to help the bottom end on my sons KX65. It does work as advertised, but it is a subtle change to the power band. My best results included Boyeson Power Reeds and a Steahly Offroad 10oz flywheel weight. The bike is way easier to ride and much more fun for my son.
The install took time to get to the reed valve, I had to remove the sub frame, gas tank, etc. not the products fault, its just in a hard to reach area. The piece fit perfectly, even with VForce reeds. Putting the carb back into place was tight, but fit very well. After installation, the bike has much more noticeable power, didn't even have to rejet the carb. I would definitely recommend this product to my friends. Absolutely 0 complaints at all.
I bought this spacer and a set of boysen pro series reed pedals for my kx 125. It now has more torque/power of of the corner. It has better throttle response and is smooth all the way through. Great buy!
