1998 kawasaki vulcan 800 dies when i accelerate
Same thing happened on my 97 vn800. It's possible that your kickstand safety switch is stuck in place, making the bike think that the kickstand is still in the down position. Clean out the switch with some brake cleaner spray and then spray wd-40 on it. Move the kickstand up and down to further lubricate it. The switch will now smoothly move in and out instead of being stuck in one position. I bet that will solve your problem.
Starter spins but doesn't crank over

Engine Problems
-
1
Check the level of fuel in the gas tank if the engine
stalls, misfires or will not start. Refill with unleaded gasoline if the
fuel tank is empty.
-
2
Examine the condition of the fuel if the gas tank has
adequate levels. Gummy or watery fuel may be contaminated. Take the
Vulcan 800 to a mechanic to have the fuel tank drained. Refill with
fresh gasoline.
-
3
Use the choke and try to restart the engine if the weather
is cold. Move on to the next step if the engine still won't start or
runs improperly.
-
4
Remove the spark plugs from the Vulcan 800's two cylinders,
located underneath the Vulcan's seat and front console: Carefully pull
the spark plug cap from each, turning each spark plug counterclockwise
with a spark plug wrench, and lift gently from each cylinder.
-
5
Inspect the electrodes of each spark plug. Clean any carbon
buildup with a sandblasting device or high-flash-point solvent and a
wire-bristle brush.
-
6
Replace the plugs with new NGK CR7EA or ND U22ESR-N spark
plugs if the electrodes on the original appear burned, white and brittle
or cracked.
-
7
Set the spark plug gap between 0.028 and 0.032 inches. This
gap measures the distance inside the hook at the end of the spark plug.
To widen this gap, use a spark plug gap tool to pull the hook out gently
to the desired gap. To shorten the gap, press the spark plug's hook
against a firm, level surface.
-
8
Restart the engine. If it still won't run properly, take the Vulcan 800 in for repairs.
Starter Motor
-
9
Check the engine stop switch located on the left handlebar
if the starter motor won't work and the engine won't turn over. If it is
in the "OFF" position, switch it to "ON" for regular operation.
-
10
Check to ensure the clutch lever is pulled in and that the transmission is shifted to neutral.
-
11
Check the main fuse, located underneath the Vulcan 800's
seat near the rear tire. If the connection in the center of the fuse
looks burned or broken, replace it with a 30A fuse.
-
12
Check the battery, located under the Vulcan 800's seat.
Unscrew the battery bracket bolts with a wrench, and remove the battery
bracket. Remove the battery leads, first disconnecting the lead from the
negative terminal and then the positive one. Carefully lift the battery
out of its case.
-
13
Clean any corrosion from the battery terminals using a
wire-bristle brush. Clean any debris using a solution of 1 tbsp. of
baking soda mixed with 1 cup of water.
-
14
Charge the battery to 12 volts before reinstallation using a separately powered charger.
-
15
Reinstall the battery, connecting the lead to the positive
terminal first and the lead to the negative cable second. Put a light
coat of grease on top of the battery terminal to prevent corrosion, and
reinstall the bracket and seat.
-
16
Operate the electric starter. Take the Vulcan 800 in for repairs if the engine still turns over slowly.
Overheats
-
17
Do not idle or operate at extremely low speeds for extended periods of time, as this can cause the engine to overheat.
-
18
Check the engine oil levels by removing the cap and dipstick
from the oil filler, located on the bottom left side of the Vulcan 800.
Dry the dipstick with a shop rag, return it to the oil filler and
remove it once more. Engine oil levels should be between the "H" and "L"
marks on the dipstick. If not, refill with SAE 10W-40 engine oil.
-
19
Check coolant levels in the reserve tank by situating the
Vulcan 800 on a level surface and observing the visible level in the
tank's transparent hose. Levels should be between the two marks on the
side of the hose. Refill with a solution of distilled water and
antifreeze if coolant levels are beneath the lowest mark.
-
20
Restart the engine and take the Vulcan 800 in for inspection if it continues to overheat.
SHOOTING GAS OUT
Are you sure it's not gas mixed with oil? Sounds like the carbs are overflowing and filling the crankcase with a gas/oil mix. The rubber hose at the head should be for exhaust blow-by fume recirculation.
What would cause the rear
It could be that one of the Pistons in your engine have locked. This can happen if the motor chassis breaks, or the motor gets too hot and the piston expands due to the heat, gets stuck and damages the engines internals (and if unlucky the valves as well.
I had this happen to me once on the Highway. All of a sudden, the back wheel of my Aprilia blocked while I was going 70 Mph. Not a good experience. In my case it turned out the cooler had failed, and the engine overheated.
Hello! I have a vulcan 800 classic 1998. I bought
well of corse its true. its like sticking ur hand flat into the wind when ur driving ur car. its all wind resistence. if u were to somehow lean the windguard back about 6 to 7 degrees it would make a wind bubble over you which would make it easier for ur bike to flow into the wind. more or less like drafting. hope this helped
1998 kaw vn 800 classic has no oil pressure,
On most of the older Kaw's they had a plastic oil gear and when this brakes then you will have no oil pressure. You can go here http://www.gadgetjq.com/gadgetsfixitpage.htm , his page has all the information on Vulcan Motorcycles that you would ever need to know. There is information on there on how to replace the plastic oil gear or the POG as we Vulcan riders call it. I’m happy to help further over the phone at
