[QUOTE="DualSportr, post: 85469, member: 19592"] It's a four valver. Very unusual engine design (unless you're used to working on BSA's), the clutch oil is separate from the crank/valve train. It's a great idea, and will keep things cooler and running better longer. The head runs two titanium intake valves off a regular cam/rocker setup - with one cam lobe & one rocker per valve. The exhaust valves are steel, and run off a single roller rocker setup for less friction with the heat. Although the 5 valve design works exceptionally well for the Yamie, it's not necessary to have 5 valves to have superior flow characteristics. After seeing the CRF, it really looks lighter and faster than the YZF -- hey, if Heath Voss can pull a holeshot and walk away from the best in the world for a lap or two...I mean, it's obviously not the rider in this case. Nothing against Voss, but HE's NOTHING against Carmichael, McGrath or even Ferry ;) From what I have heard from the people I trust, they've told me not to buy a WR250 yet. Since they know I love the CR chassis more than the Yamie, I believe it's a round-about way of saying Honda has a 250 four stroke in the works. From the sounds of it, we'll probably be seeing spy photos in the next 9 months to a year. [/QUOTE]
