If it's not red hot,there is a real problem. Flames coming out the end? Naaah, snot right.. not just cruising, maybe if you nailed it or made it backfire, yeah, flames, but riding around? No.

And Justin, the pipe was not flaming at cruising speed at all. It only had flames coming from it when we pulled off the highway at a stop sign. It was like there was too much fuel going through the pipe and getting ignited by the red hot pipe.

A few of us are rejetted a bit on the rich side, admittedly, but yes I have seen the ghost flames before and remarked on them as "that's neat looking".

The wife and I both noticed cherry hot exhausts when looking from the back.
And it does add a bit of rear light like a second running light.

On another note:
Mine is running a bit rich, so my exhaust pipe is turning a bit dark blue/black and now the dyna is doing the same in the middle.
So I have turned my air/fuel screw in one turn.... hopefully that will help.

your adjustment is the pilot screw or idling to low throttle.
the color happens from the cruising speed or mid throttle.
and blue to black is lean.
best you can do is gold.
I'd go 1 step higher with the main.

and there's nothing you can do about the muffler turning colors 'cept blu job

The pipe still turned red hot as seen in the pic. Wonder if the flames from highway speeds are something that would be fixed with fixing the exhaust leak and a rejet?

The devil are in the details,
how hot
how long
flames at idle or flames at speed?
right now all you can do is guess.
get a air/fuel gage and then you'll know.

No flames at speed. When we got off the highway and were at a stop sign, flames were coming out when I was revving the engine. We had been on the highway for about 15-20 minutes at 65 mph. The pipe was red hot, but the exterior of the pipe really didn't feel very hot.

The pic I posted was just tonight after about 10 minutes of riding at 35 mph. No flames at speed or at idle revving. Still red hot, though not as bad as when we went on the highway. Again, the pipe was not very hot on the exterior.

It seems that it will only have blue flames coming out of the end when I rev the engine after going at highway speeds.

The flames come out the exhaust when you rev the bike.....because when you close the throttle the fuel jets in the carb are closed and very little fuel can flow out the only jet that is open....which is the pilot jet. The mixture is so lean the spark plug cannot ignite it in the cylinder, so the unburned mixture flows out into the exhaust and the hot header and muffler ignite the mixture in the exhaust system....and flames go out the back of the muffler. (Why are your revving the engine when sitting at a stop light?....It should be able to sit and idle while waiting for the light to turn green - The engine would be just as happy to wait without the revving).

Sound like your bike is running like it should.

Seems like somebody said if there is a converter in it, the converter is sort of like a gray honeycomb type material.

If it has one, the converter is always red hot once up to running temp.

Reply #15 in this thread has a pic of the catalytic converter in the dyna. That might help you to identify if it is with or without cat.
