I installed a set of used cobra pipes on my 2006 vtx 1300. I should say now it hasn't been ridden in 2 yrs, just started occassionally. I started it up one day and white smoke started billowing out of the exhaust. I shut it down and there was fuel pouring out of my exhaust. I removed my air filter and the intake housing was full of fuel. any ideas as to what happened?

Thanks for the want details: you do have gas in it? It is fresh gas? Does the engine crank? Did you turn off the choke? What color is the tank?

Have you checked for spark?

Rich, there are no recurring issues with the vtx, but one thing i have seen a lot with the vtx's is when they sit around and especially when they are for sale and get started a lot with out being ridden the plugs get fouled easily. i would suggest you check and replace the plugs if they are carboned up and black. also you may want to get a fuel additive to help clean out the tank and carb, i like the lucas fuel conditioner myself.

if all you have is slip ons, leave the jet alone
you could benifit from a tweak to your A/F screw
If you put on an open air intake you would benifit from a carb tune

A factory Pro carb kit using a 215 power jet and a 58 pilot with a neddle in the 4th notch will run with open pipes and open air box.

There is a mod called the "scar" mod that will allow your factory parts to be tuned pretty stinkin good.

Good Luck

Black smoke could be unburnt fuel .Check your air cleaner unit it may need a change .And also check that your plugs and you have a spark on all plugs .

it is and it is not. the pipes are too big. you need to have the heads looked at as well as you may have burnt valves going on. i know the big pipes look good. god do they look good. get the 1 1/3 in or the 2 in od pipes and put the big pipe sleeves on them. keep that big pipe look and always have bright shiny pipes. you do not have the proper back pressure in the exauhst. have your cylinder pressure chrck as well.

a back fire is to much fuel going down the exhaust and igniting, if you changed the exhaust pipes or allterd the air cleaner you will need to get it set up on a dyno . the air flow meter could allso be playing up a dealer repair really.

your pilot jets may need to be replaced as your engine is using them at low & idle speeds,not sure if you can obtain them though

If you have used Dyno jet kit I have had a kit come through with smaller main jets than the stock ones causing it to run way to lean.

Since you removed all of the back pressure,You will need to have the carb and timing adjusted to match the new exhaust flow
