Or more likely than being too rich it probably needs larger main jets. My stock NH750 would loose power at large throttle openings, it actually accelerated faster if you backed off some. It was more noticeable after doing the washer mod, because that bumped up the midrange. Installing larger main jets fixed it. Sent via BlackBerry by AT&T
