Hey guys, I just picked up a 99 I/S and need a little help. It starts fine but I can hear a little miss on the right hand side. The bike has low miles and has been sittin for a year, but the guy told me the carbs were cleaned last year. I think one of the carbs might be clogged again. Is there a way to tell which carb is clogged, like pulling the plugs after I run it or something like that. Thanks Update Friday 9/4 Thanks for all the suggestions. I used some Techron like suggested and ran the bike at the house and let it sit over night several days, then took her out for a ride for 20 miles and things started to clear up. One more ride and the Valk is now running like it should.  |

Try dumping a can of seafoam or techron in a tank and ride......if its a minor thing it should clear up

On a cold start and at idle you could feel for heating variances at the exhaust headers. Don't get burned though, start cold. It may be enough to determine a cooler header.
I highly recommend Techron, dump a 12oz. bottle in the tank. Ride it enough to get the mixture in the carbs and let it sit, may repeat.
You might also want to check the carb diaphragms for a pinhole, tear or improperly seated.

Well I'm afraid to ride it too far, dont have much power, but I could ride it around the neighborhood. Seems like it idles fine but when you put a load on it, its not all there
I'll try the header thing tonight and see if I can feel a heat difference. Any other ideas?

That doesn't sound good. Have you drained the gas, all of it from the carbs too? Fresh gas throughout might make a difference. Make sure the choke is off. Make no adjustments until this problem is solved. Always look at it like this. If it ran good before, there is no reason for it not to run good now. There is only one single problem causing this to happen now. Not multiple things. Look for the simplest and most obvious reasons. Idling good is an indicator there is nothing seriously wrong. Those are CV carburetors. If you are not familiar with CV carburetors you may be misjudging response. Go slow! *** |

I'm gonna drain the whole thing tonight or tomorrow night. I can definatley hear the problem on the right side, you can hear it in the exhaust on that side. Just a slight burp while at idle, more when you give it the gas. Guy said the carbs were cleaned last year by Honda, but then he did not ride it but once or twice.

Another idea might be to pull the plugs, if not done already and check what they look like. Could be a bad spark plug too...

... Seems like it idles fine but when you put a load on it, its not all there... That sounds like the classic dirty carb(s) to me. It really doesn't matter that they were "cleaned" by Honda, who knows what the dealer actually did or didn't do. Take it one step at a time... before tearing things apart or checking temps on headers, etc.... do the simple thing first that you have already been told about... pour an entire bottle of Techron or Seafoam in the tank... run it for a bit and LET IT SIT for a day. Patience, patience... take it for a decent length ride (even close to your house)... hold it in the same RPM range where it starts to miss/breakup... you will start to feel it clear up. Give it time... trust me, these guys here know what they are talking about! I had the exact same thing when I bought my 5000 mile - 99 I/S last year... two tanks with Seafoam and it cleared right up. |

Ok I'll try the SeaFoam route first. I hope its that easy. This Bike is a 99 I/S with only 4300 miles on it. My other I/S just got wrecked, I had 96k on it.  |

OK I started the bike last night to move it and I noticed that the #3 header was cold. So my #3 cylinder is not firing. If the carb is too clogged up to fire that cylinder will the SeaFoam even help?

Ok, pull your #3 plug and ground it to confirm spark. Got spark! ok. Time to get serious with the chemical cleansing. After the Seafoam, that I used to use too, if there's been little or no improvement I would move onto Techron. I've experienced it's better effectiveness over Seafoam. I would dump a 12oz. bottle into a partial tank of fuel or a 20oz. into a full tank. Run/ride enough to ensure mixture (10 Miles) and then park it. Let it soak over night. Repeat the run/soak process 3-4 times. If you notice a difference I would maintain a Techron mixture for several tanks of fuel. But reduce the amount of Techron to around an oz./gallon. If it isn't cleared by this method or time you're likely going to need to get into the carb for thorough inspection and cleaning. |

+1 for TECHRON, serious cleaner I use seafoam for preventative maintenance only. Tried both on three different Valkyries, Techron successfuly cleaned clogged jets for me and saved me time pulling, cleaning and or re-jetting. (IMHO)  |

Yep, that's the stuff. Couple of bucks at WalMart. |
