Another problem!

[BoomerCPO]

2006 Midnight Venture........Left rear cylinder is now gas fouling the spark plug. I'm on the 2nd plug within 10 days now.

 

Is there something specific I can do to eliminate this problem......and would switching to a hotter plug do the trick? I'm running NGK 4929 plugs in all cylinders now.

 

Regards.........Boomer

deleted my comment.. not sure what could be causing this problem and dont want to guess.

Run a couple of cans of seafoam thru the tank. Sounds like a sticking float on that carb.

the good thing is its covered under warranty. You can also try letting the bike suck up pure seafoam thru the fuel pump and let it sit in tha carbs overnight. She won't want to run but they will run. Or mix 50/50 gas and seafoam and let the fuel pump suck that into the carbs and let it sit all night.

I'm writing down all the responses I get on this post so I have a checklist of things to work on regarding this problem.

 

Thanks for the responses so far guys!!

I 2nd that,

 

Give the stuff a few days, to work its magic.

 

If that does not work, then start considering, plug wires, maby Ing Coil, or TCI.

Buddy has it. I do the 50/50 thing anymore because it won't want to run on pure Sea-Foam. Hard to restart after sitting all night. Run some 50/50 in it let it sit overnight then dump the remainder in about 1/4 tank and run it thru.

[BoomerCPO]

OK.....I'll get some Seafoam and try that. I sure as heck don't want to pull the carbs and go through them!

 

I'll post an update results here if I can find the thread after it falls off the back of the spreader.

 

Thanks guys!!

If you hurry we can keep it here!!

ROFL!!!...........OK.....WallyMart had no Seafoam.Advance Auto did. Normally $8 a can but the Manager is a Patriot Guard Rider soooooo.......I got 4 cans for nothing.

 

The bike has roughly half a tank of gas so I put 1/2 can of Seafoam right in. Ran her hard all the way home for a distance of about 15 miles. Tomorrow I will run her hard again and try to burn off the remaining gas in the tank. When I re-fill the tank it will get a whole can of Seafoam just for good measure.

 

I'll be monitoring the plug performance. Carrying extra new plugs with me just in case.

 

Regards....and thanks for the advice guys!.........Boomer

Hope that gives you an even bubble, Chief (you know what I'm talking about).

[Yammer Dan]

Dump the rest of that can in before you get gas and run most of it out before you get gas.

[BoomerCPO]

Update.....So far I have run 1 full tank of gas with use of 1 1/2 cans of Seafoam.

 

I am down to 1/2 tank of gas and I just added the last half of a can of Seafoam.

 

Drove around for 5 hours today at speeds from 40mph all the way to 75mph.

 

No fouled plug as I type this. Bike is running a LOT smoother and is more responsive to the throttle too.

 

Tomorrow I will run out remaining gas/Seafoam and do a full fill-up with high test gas and see what happens. If the plug does not foul I'll be one happy camper.....and I'll continue adding Seafoam in moderation for the rest of the riding season.

 

Regards to all..........Boomer

Hi Boomer, per chance your TCI is or goes bad, I have one with only 13K mi on it cause I switched to the Dyna ignition module. I live in Bristol so maybe we can connect someday. I ride out your way once in a while.

Thanks for the tip Brian. If the SeaFoam does not resolve the "sticky float" problem then I will take the scoot to the Dealer for Warranty work to correct the problem.

 

Shoot me a PM and I'll tell ya how to find me. I'll bet you have driven past my house more times than you realize! LOL!

Sounds like you got it fixed Chief !!!

 

Say, I see you are in Conn. If you happen to ride thru Falls River, Mass. Stop at the U.S.S. Mass, BB59. My dad was Senior MMC on the Mass from launch till the end of the War.

 

I was a sub chaser in P-3's, dureing the 60's. Worked the N. Pacific.

Hello Keith, Don't know if this is your problem. Check and see if fuel is coming from the Carburetor vent hoses.

 

I had a problem with my 02 RSV. To make a long story short. I was smelling fuel and running rich. I could tell this from the black smoke coming from one of the tail pipes and the smell of fuel when it was running. I then found that fuel was coming from one of the carburetor air vent hoses (there are two hoses left and right side, that hang down under the air cleaners) I tracked this down to a carburetor that was internally leaking. I removed the spark plugs and identified which carburetor was leaking by the fuel in the cylinder and foul plug. The fuel was also running down the cylinder into the oil.

 

The fixes. I removed the carburetor, disassemble, clean inspected, replacing the needle and seat, set the float levels. Then resembled the carb. Then sync the carbs. Problem fixed.
