1986 Suzuki LS 650 Savage - Answered Questions & Fixed issues
No power out of solenoid
You have a bad solenoid.Time to replace it. Make sure that you have power going to the trigger wire when you press the start button first,though. If not,the problem couldbe in the button or wiring.
Engine backfireing suzuki 650 ls
Most of the time it is the timing the exhaust valve is opening when the motor is ready to fire or problem 2 could be valves not seating properly

Yea these carbs can be a real pain sometimes to get right. First thing you need to do is varify the float seat is working and totally stopping all fuel flow.... and all the jets, main, pilot and choke circuit are absolutely clean. Bench test the float needle valve by connecting a hose to the carb fuel line nipple and letting gas gravity feed as it would in a run position. if it tests ok, remount it on the bike...
i'm guessing you have a vacuum petcock on this year model? If you do, it needs to be inspected.
In the "on" position you should have no gas flow coming through the petcock, In the "prime" position it free flows. If there is a hole in the diaphram the engine will **** gas and not air (vacuum) through the hose and it will flood. If you don't have a vacuum line on your petcock then it is a different kind. Be sure to check your crankcase, it could be way past full with gas that has entered, dont start your engine like that...drain it all out. make sure the air filter is dry. You will have to replace the spark plugs...a gas soaked plug won't fire.
Good luck, i hope this helps.
My bike backfires bad but
Could be you have air leaks in the intake manifold connections causing a lean burn situation, which can cause loud noises from the exhaust, fireing back through the carb/injectors, and the pipe and engine to get extremely ho
with engine running, spray carb cleaner over and around the intake connections. If you hear the engine change tone or smooth out in it's running, you have found the leak. Fix the leak and the other problems could go away. If the bike has been setting for a length of time, your jets and passages could be gummed and needing a cleaning. If there is a possibility of gummed jets, pour 1/4 to 1/2 can of SeaFoam into the gas tank, lock down the front brake and rock the bike back and forth to mix the gas and SeaFoam. Start the bike and run at a high idle for a few minutes. Shut it down and let it cool, then do it again. If it is gummed or dirty jets, they should start to clean up shortly.

Hi,,you have gunk in the float needle,that is why you are fouling plugs and fuel is coming out the overflow.
carb needs to be removed and cleaned.
How much oil does it take?
1.9 quarts if you only change the oil. 2.5 quarts if you also change the filter. I have the manual if you have more questions later.
I got a buddie with
The motor must be on TDC when checking valve clearance.
The motor must also be cold, not warm or hot.
IF you don't know where TDC is then pull off the cap so you can see the rotor/flywheel turning and it has marks on it. turn it until you see the T mark is lined up. check clearance.
If no clearance turn the motor one complete revolution until you see the T mark is lined up again, now check the clearance. if you get clearance on TDC this is the compression stroke. this is where you want the motor when checking/adjusting the valves clearance.
If you don't get clearance on either mark, then it could be a bad timing chain, stuck valve.
You'd have to pull the rocker cover off and inspect the timing chain.
To inspect for a stuck valve, watch the valves as you turn the motor over, and see if they are moving at all.(inspect that they are moving throught the cap you removed to check adjustment).
As for the alternator, you can ground it anywhere on the frame or motor, because the frame/motor is grounded to the battery.
Oil change
The sight glass should show oil whenever the bike is stationary and level, either hot or cold. The warm oil concept generally applies for the easy pouring or viscosity of the oil. Warm oil flows better and is easier to drain from sumps, hoses, radiator's etc. Warm oil will drain better from all areas of the engine to give a better indication of the total oil in the system. The sight glass is generally hi-lo levels from top to bottom. Cheers.
