okay so yesterday it's 50ish,and i take baby out...3 days previous i stopped to get a soda(1/2 tank of fuel,this statement will be relevant in a few words)come out,start miss m, she starts to idle way up(about 1800-1900 rpm)then bottoms out(about 500-600 rpm)almost dying,then repeats.this went on for about 2-3 mins,i reved her up during this process a couple of times but she continued her up and down.then she idled like nothing happened,and ran fine for the duration.so yesterday i called the dealer to get her 600 mile oil change,when i got there i mentioned what happened to the service mgr.,was told if it didn't repeat for them keep an i on it.low and behold when she went in she repeated this hysteric for the mechanic and promptly died on the lift.(by the way she never pushed any trouble codes through either sequence)by the time i got to the dealer,iwas low on fuel and the low light came on(a gallon of high test at the dealer that they said was neccessary cost me 6 [email protected]#$%^&*)indicating 1.6 gals left.so i answered all their ?'s truthfully what grade fuel do i use(highest i can get at that station),did any mice have access to the bike(no),was the fuel low when it happened the fist time(no),did i add anything to her fuel(no),any how my instructions were to keep an i on it,bring back if continues.can anyone diagnose for me?is this common?thanks for insite!!!
