Description
This item is proudly made in the USA.
New set of Boyesen Rad valve’s part number RAD36M
I used my own pictures, actual cages shown.
Will fit the following models.
RZ350 1984-1985
YFZ 350 Banshee 1987-2012
- Maintain flow velocity through the valve and redirect intake charge for more even distribution to intake ports
- Made of one-piece aluminum castings and bolts in easily; no modifications necessary
- Provide quicker, sharper throttle response and more horsepower throughout rpm range
- Specially-designed reed cage holds Boyesen’s patented dual-stage reeds
- Boyesen’s hot RAD valve provides plenty of torque
This RAD36M is bigger ID compared to the RAD36A which are for the stock size 26mm carbs. These 36M style cages are for modified engines when using the stock carbs up to 33mm carbs. The ID holes are 31mm across.
On my 2 banshees I have Vforce-4 in 1 & these Boyesen rad valves in another. Both ATVs are almost identical in setup & I feel that both company’s cages do a great job & run exceptionally well. However, the Boyesen reeds last way longer compared to the Vforce & that is about the only difference.
Don’t forget both companies make these here in the USA!
