[QUOTE="Rich Rohrich, post: 77002, member: 16241"] Probably. With the stock WR cam timing the reduced valve overlap due to the advanced exhaust cam timing [b] could in theory[/b] have a positive effect on low rpm torque, but the trade off of the early exh blowdown cutting into the expansion cycle (power stroke) would probably be a wash in practice. Engine braking is likely to be effected more than power. Having gotten a few rides on a YZF250 and seeing how it performs, my GUESS would be that in an engine this small the compromised stock WR cam timing would have a detrimental effect on torque across the board. Unfortunately I haven't had the opportunity to get my hands on a WR250F so all I can do is [b]speculate[/b], sorry. [/QUOTE]
