Bling with function.

By   on  Verified Purchaser

The Boyesen kit is top quality and well designed. The housing has an angle that helps keeping the coolant hose spaced from my aftermarket header. Perfect.

Great product

Good grief I love this thing. No more emptying the coolant to change the oil. My bike has actually quit overheating which seems to be an issue on the RMZ250.
