Maybe it's just me, maybe I was used to my 1998 yzf400. Either way the power delivery on my 426 just isn't cutting the mustard. To sum up the power band in one word, SLOW! I have had it since it was new, it is bone stock. I am no pro rider but I know slow when I experience it. It is not doggy slow, but it is not what I expected. I know that a lot of people will answer this post with a note about their shoulder popping 426, but mine barely scoots me back on the seat. What could be wrong? It's new, It's never been worked on, I'm at 500' elevation in California. I was expecting great things after coming off the 400f, but have been very disappointed thus far. I recently fixed the problem, but it cost me $7,500.00 and it's orange. Yeah, the new bike rips, but I would still like to fix the blue one w/o trying everything in a trial and error procedure...HELP!!!!
