I was riding my 1986 suzuki gs550es3 when all the sudden I started losing power drastically. Then it began pouring out smoke from the pipes. I let it sit for a few days, drained the carbs and it fired right up, smoked for just a minute then seamed to run fine except it still had little power. whats wrong with it?

You probably broke a cylinder ring. The cylinders are dry when you haven't started them for a while and sometimes that extra friction catches a ring just right and breaks it. A break in the ring kills compression and therefore power. Also the ring allows oil to come up from the oil pan into the combustion chamber where it doesn't burn and you get all the smoke.
Run a compression check on each cylinder by putting a compression tester in the spark plug hole. If one reading is a lot lower than the found your culprit

Why did my 97 Suzuki Sidekick suddenly, start smoking and losing power; now all oil is gone and engine knocking. No evidence of oil leaks prior?

The G16b.
so leaks after?
do a compression test, , warm , wide open throttle
spec is 180 PSI x4

white smoke (oil or steam)
or black smoke.
the color i bet is white and that be oil ,since it drops.
if all oil is gone that is the end. this must never be allowed happen.

I have an 87 virago 1000cc I know I need to sync the carbs but why do I lose power when I have it idling to warm it up before I ride? I have it plugged up to a battery charger when I don't ride for a while...

Have your battery checked. If it's good, have the charging output checked. The smoke from the top pipe may be fuel or oil. If it's blue, it's oil. If it's black, it's fuel.

2003 Suzuki GSX 600 F (Katana) white smoke

Hi, Gabe_tiff your instrument gauges and lights can alert you to most electrical and engine issues they can not warn you about failed engine gaskets or seals so your engine has to resort to old fashion alert methods of colored "SMOKE SIGNALS" here is a breakdown of their meaning:
1. COLORLESS OR SLIGHTLY BLUE SMOKE on start-up means your air/fuel mixture is the right composition and everything is well burnt in your combustion chamber.
2. BLUE SMOKE on startup is usually caused by failed valve seals dripping oil into the combustion chamber when the engine is not running.
3. YELLOW OR BROWNISH SMOKE at start-up means your air/fuel mixture is too lean. Too lean means that there is low fuel but high air mixture in your combustion chamber.
4. WHITE SMOKE on startup may be caused by a blown head gasket allowing coolant to enter the combustion chamber and may start dripping out of the exhaust pipes or mufflers. Smoke while riding is usually caused by worn out or damaged valves, seals, guides, pistons, rings, or cylinder walls.
5. BLACK SMOKE on startup is usually caused by too much fuel in the combustion chamber this can be due to air/fuel mixture adjustment too rich, accelerator pump improperly adjusted, faulty choke or not in the off position, air filter dirty and clogged, faulty carburetor float needle and seat, pilot jet too large, fuel injectors leaking, smoke while riding is usually caused by the main jet being too large or a damaged carburetor.
It should be noted that aggressive or abnormal throttle operation will cause these conditions to manifest themselves exponentially.

While riding my Suz GS500F (2009) home in the rain last night I started seeing smoke coming from the lower left side of the motorcycle. Stopped at a light and loads of smoke came up through the fairing....

I presume that you were riding it back from the dealer when you had the smoke problem ?? in that case one possible cause could be that when they serviced it they got some oil on the exhaust pipe and when the pipe got hot it burned it off. let me know if that helps or not. Alex.

I have a 1986 Cavalcade that runs great then without warning stalls out. I think the fuel pump relay is bad. Does anyone know where this relay is located on this bike?? Thanks

Does it stall suddenly...or start sputtering as if its running out of fuel. The fuel pump stopping shouldn't kill the engine suddenly....each carb will empty and you will lose one cylinder, then two etc.
If its dying suddenly I would investigate your sidestand switch....when the bike you ever find the starter won't immediately crank?

On a 40 mile freeway ride home my '01 RSV 1000 began to smoke very heavily for say 5 miles temp constant 170 then it stopped. Initially I thought I blew it up smoke was so bad did seem to lose power....

Sorry man but yes,
Aprilia especially their higher end motorcycles are precision machines they don't just start to smoke take it to a dealer you trust. If you catch the problem early you could save some money

White smoke coming from my tail pipe when I accelerate

You may have a blown piston ring, valve seals, valve guides, cracked head gasket or a cracked block, etc... It sounds major though for you to lose power suddenly and have all that smoke...
