How to solve the 2900 rpm gaging problem

I have the new air box, the latest software updates and still, there were times of stammering and backfires. Also, frequent stalls coming off the highway and trying to idle. 2006 early model. And now for the CURE! Add 3 oz of HEET to the engine. Any additive that removes WATER from the fuel. Turns out that gas station operators are adding water to the gas to increase their profits. Those scurlious scoundrels. It has cleared up my dear K12gt and I am forever grateful. - Perry Hebard I invite those that have tried this to let me know if it helps.

Water is heavier than gas. It will separate fairly quickly.ANy water in fuel is probably condensation.

Your bike sounds like it was running like mine after the new air box fix. Mine is now perfect after resetting the adaptive settings and installing version 11. All of those symptoms have completely gone and now been gone for about 7000km.

Hopefully your fix will continue to work but if it doesn't you need to do the computer reset thing or get the dealer to do what mine did. It has transformed the bike.

water in gas

All gas stations have a little water in their tanks from condensate. It stays on the bottom and is not picked up by the pump. Now when you see the tanker truck filling the tanks,dont get gas there that day. The filling action stirs every thing and you can pick up water.

Did you do a TPS reset? Sounds like a lot of dealers forget to do it.

Yeah. Some gas stations do get water in their tanks. Sometimes the boss, employee theft, angry employee, or delivery tanker. Seen it first hand (angry employee who quit).

A local Saturn car dealer had about a dozen Saturns on the back of tow trucks trying to get in for service. Manager was all upset and wanted all the tow trucks out of there as it looked really bad from sales point of view. Turns out all had watered-down gas in their tanks and all from same Chevron station.

I've had it happen on the bike as well. Usually next day when it separates out, the bike will run ratty as hell when the pump picks up the water.
