[QUOTE="splatt, post: 549582, member: 26822"] I had Eric give my 94 YZ250 the Mo-Better porting and had him set the head up for pump gas. Let me tell you this when using a lower gear=rocket using a higher gear=tractor. The power comes on early and signs off when the pipe does and it does it very smoothly. I like it better than the stock porting which had a violent hit in the mid range I also did the powervalve governor mod Eric describes in his book for this year which also helped. Steve [/QUOTE]
