The header pipe will glow red when you run it on choke, during warm up. This is normal while sitting. You shouldn't see that one you start riding it though.
The coolant drip could be just a dirty or failing radiator cap. My bike will push a little out if I completely top it off full. Hope this helps.

I have a Utica gas furnace and the overflow pipe is dripping continuously. What could be the problem?


If your Utica is a high efficiency 90+ condensing furnace, I suspect not too much is wrong. A condensing furnace removes so much latent heat from the burned fuel that it condenses the moisture out of the flu-gases. The result is a very low flu temperature, AND water.

The water must be flowing correctly down the proper drain though, or you could suffer damage to the furnace itself. If there is an 'overflow' pipe and it is running over though, the drain downstream must have an obstruction. Clean the drain out and the overflow situation should go away.

Would a home a/c stop dripping condensation after a tune-up WAY, WAY overdue?


It should drip. That's the humidity from your house. Call them out again to have them verify the drain pipe is clear. Tell them you think they did something wrong. If it doesn't drain right, it will pool inside the unit and cause the internal AC panels to rust if the drain pan (below the condenser) overflows. Or worse, it might be a source for mold to grow inside the system. The later being unlikely, but not impossible.

My 2007 yfz 450 exhast pipe glows red when running , what would cause this?


It is not uncommon for stainless steel exhuast systems to glow under normal operation. This can be seen especially at night. occasionally a lean condition can cause this also. This could have been caused by blockage in the carburator jets and passages from sitting up, An air leak at the intake manifold(rotted,cracked manifold or simply loose clamps) or a hot start plunger that is stuck in the open position due to dirt in the plunger, a mis adjusted or froze up cable. If the radiator is full of coolant and it is not overflowing while running then it is not overheating. It will boil over from the overflow tube when it overheats.

After driving a few miles temp gage indicator moves from middle of "C" and red line "H" to very close to "H" and then back to middle. When I turn off vehicle there is coolent...


Your first problem sounds like a thermostat that is sticking and only opening late. The second could be a leak in the overflow system or the radiator and piping system itself. That can only be found by inspection under the correct conditions. If the overflow bottle is too full it could also let off a bit of coolant that has expanded.

The glow plug light flashes while the engine is


this means you most likely have a burnt out glow plug or glow plug timer control or both
