Hi, Robshogs and the usual suspects are:
1. Oil tank/pan empty.
2. Oil pump not functioning.
3. Restricted/pinched oil lines or fittings.
4. Restricted oil filter.
5. O-ring damaged or missing from oil pump/crankcase junction (also results in poor engine performance).

Hi, Ron if you have changed your fuel delivery system, air filter size or flow rate, mufflers or exhaust system or a significant change in altitude your carburetors need re-tuning and if your fuel system (gas tank, filters, fuel valve and carburetor) is contaminated with ethanol sludge, varnish, rust, dirt, water etc. or your bike has been sitting for months or years without running these components must be "PROPERLY" cleaned and reassembled "CORRECTLY" before any adjustments can be made. Tuning your carburetor is fairly simple once you understand the basic principals. You engine is a simple airbox sucking air in and blowing it out, it is finely tuned at the factory for maximum performance once you upset that delicate balance by changing air filters, camshafts or exhaust systems your performance may go down the and the engine may run poorly, you need to compensate the air-fuel mixture in the carburetor in order for the engine to run smoothly and at peak performance. If you are running multi carburetors you need to sync them first and make sure your air cleaner element is clean and dry for paper elements or lightly oiled for foam and meshed elements and properly installed. Here is how and where you compensate trouble: "TIP" if your engine "BOGS" your not getting enough fuel.
1. Close to 1/8 throttle is managed by the air screw and pilot/slow jet.
2. 1/8 to 1/4 throttle is managed by the air-screw, pilot/slow jet, and throttle slide.
3. 1/4 to 1/2 throttle is managed by the throttle slide and jet needle.
4. 1/2 to 3/4 throttle is managed by the jet needle, needle jet, main jet, and air jet.
5. 3/4 to wide open throttle is managed by the main jet and air jet.
6. Wide open throttle is managed by the main jet.
If you are running lean, spark plug electrode color is white, engine runs hot and feels like it is starving for fuel you need to go up on the jet size or move the c-clip down one notch. If you are running rich, spark plug color is black or dark gray, the engine runs cool, and bogs down when accelerating you need to go down on jet size or move the c-clip up one notch. When your carburetor is properly tuned for maximum performance your spark plug electrode will be a light tan color like coffee with cream. If you prefer fuel economy over performance you can go down on main jet sizes until a satisfactory level of lower performance is acceptable versus MPH, your spark plug color will be whiter and your engine will run warmer. These tuning adjustments will only make improvements if your intake and exhaust system have no air leaks or sealing issues and the entire electrical system is in proper working order and you have no mechanical issues.

Don't hold the lever in as you kick. It is designed to get you just past TDC on the compression stroke. Try this:

1. pull in decomp lever (it should stay down)
2. slowly move kick start down. STOP as soon as the decomp lever pops up.
3. return kick starter to the top of the stroke.
4. kick smoothly all the way to the bottom. (takes very little effort)
5. no start? return to step 1.



If it still problem try check the adjustment on the decomp lever. The lever should stay down until you rotate the engine with the kick start to just past TDC on the compression stroke.

It may be ok , but many bikes flood when sitting over night and fill the sump with fuel. if the carb float doesnt quite seal.
Not sure about epa , I think it shouldnt be a problem unless carb overflows and drips on the ground, during the inspection.

What bike do you have, and are the volts/ohms in spec? You can have continuity, but not enough juice for proper spark. cleaned the ground posts with sand paper and the put it back on. then i unplugged the kill switch and then plugged it back in. then replaced the spark plug and it started right up . so try this couple of things and see what happens. You need a mulit-meter to make sure that you are getting proper juice

Hi,,remove the tape and check the connections,,when you say "everthing went dead i assume you mean all lights ect,,,check your fuse box,,,more than likely the indicator wiring has shorted and blown a fuse.

Hi dogothedeser,

You did not state what model Suzuki you have. Some batteries are on the underneath of the bike; seats are usually bolted on and can be removed by removing the side covers and then removing the bolts holding the seat on. The fuel tank usually has to come off too. This is usually held on by a single bolt under the seat.

If you would please post a comment with the Model of your Suzuki, I may be able to assist you quickly.

Thank you.
