SOURCE: left exhaust pipe is turning a gold colour for approxiamtely 12 inches from the engine

Discoloration on chrome pipes is completely normal and is referred to as "bluing". It's caused by the extreme tempurature of the exhaust as it leaves the engine. Typically it will affect the first 12-inches or so of the exhaust pipe. The problem can be worse if your engine is running too lean a fuel mixture. Since your bike is relitively new the engine might not be completly broken in yet, this will cause it to run a little hotter than it normally would.

Why one pipe is changing color and not the other? I'm not sure, one cylinder may be breaking in quicker than the other, or the mixture in the cylinder may be leaner than the other (not too likely with today's fuel injected bikes). If your bike is running and idling correctly and not overheating you shouldn't worry.

Pipe bluing drives motorcycle owners nuts, especially Harley who like to put expensive aftermarket pipes on their bikes. As a result there are a number of products on the market that are supposed to be able to remove the bluing or insulate the interior of the pipe to prevent the bluing. Stop by your local aftermarket motorcycle parts store and talk to one of the parts guys. They may be able to suggest a product that will help you resore the proper color on your pipes.

Good luck!

SOURCE: Oil leak by exhaust pipe

I am not personally familiar with a 1975 DT250, but here is a general overview. If the bike is a 4 stroke, the oil you observed could have been from the exhaust, however it is more likely that it is from a leaky valve cover gasket or a head gasket. If the bike is a 2 stroke, the "oil" is from the exhaust (expansion chamber). It is excess 2 stroke oil that accumulates. You should reduce the mix to 32:1 or even 40:1 and replace the oring gasket in the opening of the pipe. If in a pinch you can use high temp silicone, but not a good way to go.
best wishes!

SOURCE: white smoke

Are you sure the smoke is white? White smoke is usually caused by antifreeze burning.(This could be a head gasket)

If the smoke is actually light gray it is oil burning.(This would be rings or valve seals)

If it smokes mostly on startup and then stops when it warms up (It could be a worn valve guide or deteriorated valve guide seal (or possibly several) allowing a tiny amount of oil into one or more cylinders).

If it smokes mostly when you are cornering (It could be too much oil in the crankcase).

Smoke from a side pipe


Leaking exhaust pipes and deflated radiator can be the result of this. Better start with the radiator first and check if its deflated. Also make sure the pipes are tightly mounted and double check any leak.

When my bike is running I get white smoke from the right side exhaust and the right side also blows harder than the left. What could this be?


IF you are running stock pipes (not "True Duals"), the right pipe exhaust ALL from the front cylinder, and SOME of the rear, and the left pipe only blows SOME of the rear alone.

The stock rear pipe splits, some going to the left pipe by itself, and the rest going to the right pipe WITH the exhaust from the front cylinder.

Now, white smoke usually indicates moisture.
Being a (non-VRod) Harley, that eliminates the liquid coolant, because there is none.

Next up that comes to mind is condensation.
BUT, this would burn off fairly quickly.

So is the white smoke only at first, or even when warmed up?
And if warmed up, is it actually coming OUT of the pipes, or OFF the pipes (like some oil burning)?

Stuck valve


It is not unusual for the left side exhaust to be hotter. It hooks to the rear cylinder that has the least air flow and consistently runs hotter.
If the back pressure draws a dollar bill in when placed at the end of the pipe, this is typically caused by improperly closing valves.

My first guess would be a sticking exhaust valve.

On my pipes one side is hot and the other is cold


Check the pipe right where they come out of the heads. It depends on what type of exhaust system you have on your Road King. If the stock exhaust is on the bike, the rear cylinder exhaust is directed to both mufflers. With the exhaust from the front and part of the exhaust from the rear cylinders going to the right side muffler, it gets more exhaust than the left side and runs hotter. Like I said, check the temp of the exhaust pipes at the cylinder heads. If one of them is cold, that cylinder is not firing. As long as both of the pipes are hot there, you're fine. Just ride the bike and have fun.

Ride Safe.

1995 yamaha blows more exhaust on the left side than the right


Assuming the bike idles smoothly and is not smoking you can pretty well rule out bad valves and piston rings. If the air filter is clean then intake should be okay. Are the valves set properly? Is the decompression lever and valve working properly? I assume there is not mud plugging up the pipe. That pretty much leaves the muffler on the right side having an internal collapse and is restricting the flow of exhaust gases. Remove the mufflers and see if the pressures are equal at the head. If the problem is still there then have the shop do a compression check. It is possible a ring has broken or is frozen in the ring groove. This would let some compression into the gear box and account for the lower exhaust pressure. I hope this helps.
