The 42 mm kehein off of the 04/05 450Rs is way more popular, and I've heard great things about it.

I have a 450r carb we took off our 440ex, man this is the cheapest way to get good horse power. Iam Just about done parting out my 440ex & did not know if I wanted to sell my 450r carb or not, but i have a yfz450 know & I figure what am i going to do with this carb. Sell it. Good condition $135 shipped.
Let me know if interested, I will be selling the rest of what is left next week

Thanx Wade
