After doing a ton of research and reading, I've decided that I would like to concentrate my energy and focus on maximizing the cylinder head on my '00 YZ426 instead of doing any displacement increases. I've emailed and talked to a few specialty shops about this and am leaning toward one in particular. What concerns me at this point is the possibility of losing the crisp throttle response that I've spent so much time and energy to attain. I have an incredibly powerful low-end snappy response that I don't want to lose or diminish one iota. Is it possible to retain this attribute. . . . and/or even enhance it while still adding to the mid and mid-top? I'm an engine-sensitive rider who avoids the rev limiter by about 1200 RPM so I'm not looking for a high revver. If I could keep or add to the off-idle power response plus adding in the mid, I would be in a higher Heaven. I use C-12 fuel and enjoy doing the jetting for maximum return. Any advice, ideas, opinions, experience...etc. would be appreciated.
