2002 R6 Idle Troubles?

So my 2002 R6 seems to not be able to idle stably. I get it set to about 1,200 RPM's with the idle adjustment knob. Then as soon as I twist the throttle it revs up and stays around 4 grand. I then have to turn the Idle knob down to get the RPM's to drop back down to idle speed. But then I can twist the throttle and it goes right back to 4-3 grand and stays there till I twist the Idle adjustment back down again. It eventually gets to where my idle knob is turned all the way down so the bike either wont idle at all or it revs up too high as soon as the throttle is touched. The idle speed only stays stable when the throttle is not touched (I know that sounds stupid). It was doing the same thing before I did the re-build so I am running sea foam through the tank to hopefully clean gummed up areas in the carbs. Any ideas what might be causing this problem?

Must have been the carbs gummed up because when I got home from work I fired it up after the sea foam had sat in the carbs all night and it kicked a big puff of dark black smoke then ran smooth as a baby butt. Instant throttle response and then drops back to idle. :)

Thanks guys,

Sea Foam is engine magic. It is was designed to be used in Marine engines that cannot be disassembled at sea. Sea foam can be added to your oil and your gas. When you run sea foam through your system the internals look new and it cleans all residue out of your drive train and carbs.

Just go to Autozone or Advanced and pick up a can. You just pour it into your gas and your crankcase (in the right amounts). Your bikes exhaust smokes for a few minutes then runs really clean and smooth. I have however found the root cause of my problem is lean jetting due to my K&N air filter and shortened Leo Vice exhaust. A new DynoJet kit is on the way.:)

Same exact hole you put your oil in.

Re: Idle trouble solved. New problem.

My 2002 R6 had the same problem with the high idle problem. I have had this problem since I bought it. I checked TB, sticky parts, vacuum lines, throttle control, fuel delivery, added sea foam, checked everything top to bottom. 2 days ago I tore it down again (5th time gettin good at this) and found no problems again. Set up Repair work @ my Yamaha dealer, put it back together the same way and guess what? Idle problem gone. rode for an hour with good idle. (around 1000). Now I have good idle but a miss in the engine. Im thinkin fouled plug. Any body have plug foulin with sea foam? If not, could my idle problem been makin the bike run lean causin the plug to foul? And I have either lost horsepower or im gettin used to the power of the bike which could be, but it seemed to have more power before with the idle problem. Wadda ya think. Sea foam, Idle issue, power loss...any thoughts are considered...God I love this bike....:YEA

Tighten that bolt. Because a bike engine is such a high performance system (your average 600 makes on average 120 horse, that's 200hp/liter naturally aspirated, so double the automotive performance benchmark of 100hp/liter such as bmw M engines, honda B series vtecs and K series, and everything else that makes 100hp/liter na), a tinyest change to anything in the engine will make a huge difference. You can feel a power loss and a mpg drop when you have a pinhole in your exhaust on your cage, imagine the difference it makes in a 4-5 times higher performance engine.

Shit, my 6 would barely stay running and would die if I tried revving it open header.


Seafoam is amazing, the only mechanic in a can that works. If you put it in your oil, DO NOT RIDE. Unless you can't find anything better to do with your money than to buy a new engine. Seafoam just like any engine flush thins down the oil to where its not lubricant enough to protect an engine under load. You can idle with seafoam all you want, but don't put load on it.

Best way to flush the crankcase with seafoam is put some in (half a can will be more than enough), let it idle for 10-15 minutes, then change the oil.

Then you got the seafoam in a vac line treatment to suck it into the intake manifold and clean out the valves, combustion chambers and tops of pistons. Obviously a much bigger pain in the ass with our ITBs or individual carbs.

But in reality, if you change your oil and maintain your bike and don't run piss gas thru it, you don't have any sludge or carbon buildup to worry about. Use seafoam as a fuel additive and rock out
