I bought this bike not running and was wondering if anyone has any insight into a flat spot in my motor between 4000-5500rpm. I have had it into the shop on the dyno to get it tuned out but there is nothing working. I have the Denso plugs and they are burning fine so its not the spark plugs. It has a k&n filter in it right now and I will be changing it to a stock filter. Im running 93 octane fuel, the chain is good, so the shop has no idea whats wrong. I know there are some inteligent people on here that can probably point out something we are missing.

Take a look at the map. Alot of people try to richen it up in that RPM range. You know, if its weak throw some more gas at it until it works right. But you actually have to lean it out in that range.

no they leaned it way out b/c it was a little rich right there. the ega is reading the correct ratio everywhere thats why we are stumped

No worries. Any chance of having it tuned by a Dynojet 250?
It has always been hard to decypher a winpep chart. One of the reasons is that they use MPH instead of RPM. Also, on a Dynojet 250, they show you a corrilating A/F ratio chart.

OK I finally got a FI blinking light after putting 200 miles on the bike and all of the dyno pulls. How do I pull the code?

its the number of flashes on the light referenced to the service book - post the flashes and someone can tell you what they mean. just got a manual on PDF so can perhaps help. that's a bit drop in the curve though if the bikes more or less stock ex. the k&n...............

Its a 3 flash code....does anyone think the flat spot could be the flapper valve being wired open? my last 929 with a full acro didnt have this problem but I still had the flapper valve in???
