Easy way to check 4 idle miss?

[HellFire]

Anyone got an easy way to check for a possible miss at idle? I got the bike back from the dealer for the oil leak and now it acts like it has a half cyl missfire. Knowing them, a plug, wire or coil could be dorked up from them not giving a dam.

using a timing strobe light might work.

Geezer man, you sure are having bad luck with that dealer. I've been following your previous posts about them.

They are a specialized service department, the work they perform is very unique. Where most shops can repair more than one item per visit .... these guys only repair ONE thing at a time but manage to break multiple items at once.

Possibly they stretched a plug lead since they were taking the cover off. One way to check is to pull one lead at a time and listen for change in the engine sound. The one that does not change the sound is the one with the problem. Use caution doing this because of shock and the possibility of stretching another lead.

****!!! You cant win!! Im now thinking about doing the 10K service myself.......If I cant find a dealer I trust F'em. I can do the work no problem and If I have to purchase special tools Ill do that too!!!! This dealer thing is crazy!!!! No accountability and no support from the manufacturer. Used to be that you had to hold a standard to be a dealer of a quality prodcut....now its all about the cash! Sad really that our society has come to nothing more than a piece of paper with ink on it

Yeah, that's what I was going to do if there wasn't a "magic trick" I couldn't remember. I didn't really want to go that route for fear I'd make my own problem if there wasn't one there to begin with.

I had that happen to me once...or something similar and I probably caused the problem myself. I was connecting some electrical something or other and when I put the tank down somehow I ended up pinching one of the vacuum hoses (I believe that is what the mechanic said), they identified it pretty quick and "unpinched" it and it ran normally...I hope your's is that simple to solve.

It could all just be in my head .... I didn't have the bike for two weeks, maybe I just forgot how it sounded.





Here's how it sounds ...... you know how you can "almost" hear the three cylinders firing?
Well, it's like one of those three sounds weaker than the other two. Hence the idea that maybe one of them has only one plug firing. It comes off idle and accelerates just fine, in fact if you just crack the throttle a little, every thing smooths out and sounds fine.
I think I'll start with pulling the plugs just to check on them, R3's have such a powerful spark .... **** thing jumps over an inch gap. With that mean of a spark, it would about have to be jumping to ground somewhere to not be lighting the fire down below.
