I'm not sure which model that is but if you have a separator element that may be a good place to start.

SOURCE: 175 ingersol rand compressor putting a lot of oil out with air

It could be a failed air / oil separator filter or the steel pick up tube that goes down through the center of the oil separator (it is about the size of a pencil) could be clogged. Un screw it out of the top and see if you can blow air through it. Also check the hose leading off of it going back to the pump. If it is plugged it wont allow the oil to return and will push it into the air.

High consumption of fuel

If you have serviced the engine, changed oil and oil filter and air filter and spark plugs and cleaned the carburettor or cleaned your throttle body and injectors, and its still heavy on fuel then try the following. Adjust the carburettor air and fuel. Take off the distributor cap and clean the rotor and spark pionts in the cap of carbon build up by means of light sand paper. Same applies to the spark/ high tension leads and coil lead metal connection points. Check distributor timing as well. If the engine smokes, do a compression test. If results are beneath factory specifications, remove cylinder head, replace the valve stem seals and re-seat the valves and or replace the pistons and piston rings. Basically engine overhall

I have a 1986 yamaha 540 srv snomombile and when i throtle it up it bogs out and pops like a backfire do you have a suggestion on what is causing this and how to correct it?

You should purchase a gasket and seal set, pull your motor out of the sled, disassemble the motor, and replace all the gaskets and seals. You can purchase a piston kit on line that should come with pistons , rings , gaskets , and seals.The main problem you are having is an air leak on one or both of the crank end seals. Usually the clutch side seal leaks first. If you continue to drive you will probably score one or both of the cylinders.When you have the motor apart clean your carburetors and replace your spark plug caps. NGK has new plug caps for about $5 each. If your cylinders look good i would consider doing a light hone job and ring replacement. Again if you just buy new aftermarket seals pistons and gaskets you should be able to do a complete rebuild for about $150. Then your engine will be good for another 25 years. If you are limited on funds Just replace the crank seals , clean the carburetors, and put on new NGK plug caps (about $30).

How to clean spark plugs on 2007 honda cbr

Replace the plugs, don't try to clean them. The proper way to clean plugs used to be to sand blast them. The problem was that bits of sand can remain deep inside the throat of the plug. When the sand breaks free it causes damage to the piston, rings, cylinder and valves. The only safe way to clean them is to blast them with dry ice particles. Cleaning plugs is not a big industry. The equipment required is hard to find and is expensive. You have a lot of money invested in your bike. Spring for a new set of plugs. Please rate my answer. Thanks.

I need to know how to dis/reassemble a 1974 DT 360?

A service manual ( if you can find one ) is what you need. The second thing you need is repair parts. They are pretty hard to find. Babbitt's, a well known distributor, only has parts left in stock for the top end. Go to their website,
and you can see what is left. There's also a diagram of the crankcase center halves. If you can't get the repair parts, spending hours doing an engine teardown is fruitless.

The teardown will require a flywheel puller, a case splitter, an impact driver, and a torque wrench (somewhat optional). Disassemble the top end then remove the left and right side case covers. Remove the flywheel and related electrics, the clutch, crankshaft drive gear, oil pump, kick starter, shift shaft assembly, shift drum end cap and index pins. Now remove the screws on the center case and you can then split the case. This gives you access to replace shift forks, gears, and bearings. Note that crank seals can be replaced without splitting the case.

I am not trying to be a smart *** here, but re-assembly is just the reverse of dis-assembly. This is why a manual would help. Another potential source for parts is to Google motorcycle salvage yamaha .
The normal things you would need to replace inside the center case would be bent shift forks (if shifting is the problem), busted gears, crank bearings and seals, and sprocket shaft bearing and seal. All else can be replaced by removing just the side covers.

1988 yz 250 ,lacking power,spitting oil,possibly power valve?

More than likely the majority of the problem is related to poor compression pressure. When was the last time the engine was re-built (a new top end)?

I would suggest evaluating the condition of the piston, ring and cylinder. Replacing the piston and ring and won't set you back much if the bore in the cylinder is good and it will definately perk your bike back up.

Clean that air filter too - a plugged filter will cause the bike to run rich, too.
