Sure does piss you off, like most things intermittent they never play up when you want them to. I have had the bike back to the shop about 10 times and have it booked in again next week. Each time it goes in they try something else. So far they have tried every sensor in the fuel injection system and they have even replaced the main computer black box to no avail. They have tried ten different fuel maps and in the end went back to the original that they put in with the cam I had put in from new . All of a sudden it started to blow a bit of smoke from the front cylinder so it went in and they put a camera down the plug hole and found that there was about 2 teaspoons of what looked like oil or fuel sitting on the piston. Thinking that it may have a leaking valve guide seal and was leaking onto the piston they pulled the motor down to the crankcases and in fact did find a leaking guide seal. I had them hone the bore and replace the rings, reseat the valves, put a new set of gaskets in. $1600 bucks later I have gotta say I was keen to get it back and give it a run down the road , thinking that we had it beat this time, I mean what the fuck do you have to do. Within ten klms it was idling up again and the weird thing is it would start to idle normally a few klms later. So back to the shop we go again, totally bald now from constantly pulling my hair out. The mechanic, also bald and not from age but frustration said he just wanted to pull the injectors out to have a look and found the front cylinder was black while the rear was clean. It was probably from the leaking injector but I live in hope that maybe it was sending false info to the sensors and causing it to idle up for some reason. Back on the road again and before I got to the end of the street it was idling up. They are now talking about trying a new manifold in case it has a hairline crack that is affected by the heat. So thats where the story ends for now, not the problem just the story. I will try your suggestion of turning the ignition on and off 4 times with my right hand. Resetting the computer sounds about right but considering they have have put a new computer in with no change to the problem I dont like my chances. Give me naturally asperated carberation anyday.
