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.

sending unit on engine no good .try this un plug sensor and jumper across plug end and see if fan come on if so positive sensor defect.change sensor.

serious problem you have to split the case in order to get to the forks and shift drun . The shift drum may have a bad tract that guid the shift fork and also will caus sevior shift problems if drum is damaged.

Yes. There is a converter available from most good motorcycle parts suppliers. Or you can just put a sticker over the glass for the speedo. This is clear and you can still see the kph markings and the needle.

general rule of thumb is to go up about 10 jet sizes,unfortunately it is a bit of trial and error,and you may have to swap out diferrent sizes to get the bike running right,(jets are quite cheap though)but first step about 10 sizes from standard,your local dealer should be able to tell you what jets are in it and supply replacements,if you change to a hgh flow aftermarket air filter you may have to change jet sizes again as changing the filter may effect the mixture ratio in the carbs,,hope this helps

Remove the single screw or nut that holds the speedometer cas to the tank. carefully move the case forward and release from the front or the tand. disconnect the two or three plugs and the speedometer cable and remove the speedometer case. under the case you will find a bolt holding the front of the tank. remove it along with the rear bolt. Disconnect the fuel line and the petcock vacuum line on the left side and remove the tank straight up. As you remove the tank some models have a vent line on the right side under the tank that must be removed. Don't lose the rubber knobs that hold the tank straight. they are on the frame at the bottom of the tank. Good luck.......Jim

Sit at a traffic light till the temp reaches about 220, it should start about then. My fan has come on 3 times in 8 years.

With your engine off and key ON:Pull the one and only wire that goes to the sensor bolted on the radiator's top end, and it is located near the coolant hose. Not the other one with the two wires on it.When you pull it off the sensor, the light (if it is still on) should go off.Then touch the wire's end you pulled off the sensor, to the chassis. The light should go on again.If this is the case, replace that sensor.If pulling the wire off the sensor, the light is still on then follow that wire all the way in the harness because somewhere it is damaged and grounds on the chassis.

The fuse box is under the seat.You have to remove the battery and its the back box on the left side jest pull it out.

If you do not go thru your local dealer you need to get your manual and it will tell you the exact torque amount.

I have a 1500 vulcan, on my bike its 60 lbs.

todays bikes run perfect on Regular, which can be from 87 to 90 in some cases. you would not damage the bike by using pump gas like super or premium but anything higher may cause problems. but there is no advantage to using premium

the timing chains on the vulcan 800 are self adjusters, you do not need to manually adjust them.

Hi, apparently the vulcan 1500 has been FI since 1991 through till 2008

Hello William, the noise you indicate from the bottom left of the engine could be from the crankshaft damper. This is usually more of knock than it is a tick. It's hard to say without actually hearing your bike. A lot of Vulcan owners have reported this noise. I would swing by the service shop & let them give a listen, they should be familiar with it. Also, if you are using a fram oil filter, i would replace it, they have been known to cause problems. I hope this helps.

You have several possibilities. Burned out light bulb, blown fuse, bad switch, loose wire connection and a broken wire. Track it down with a multimeter.

This sounds like a carb overflowing this normaly occures when the float valve sticks, you will have to remove the bottom of the offending carb, remove and clean the float valve assembly inc seating

Hi

Check if the chain is in proper adjustment. Improper adjustment to the point of being too tight will make a grinding noise. The only internal grinding possibility would be the primary drive from the crank to the torque convertor. if the chain is in proper adjustment, then if sprockets are hooked and if the chain can be pulled back off the rear sprocket at the 3:00 o'clock position to the point of being over 1/2 the tooth height or if you can see a gap underneath. Both are indications of a worn out chain and sprocket set.

the minimum for a battery should be 12.4 volts,, its probably not getting the amps that are needed, replace the battery

The settings on a carburator is very important and is a technical job than to open,clean and reset.
So it is possible that the settings of the carb had changed when it was removed and refitted. The air/fuel mixture, the throttle settings, the idle and the choke valves/jets, must be set correctly.
Make sure that the air/fuel mixture is corrected so that the correct fuel mix goes to the cylinder , if not there will not be any firing.Finally check the spark intensity on the plugs with the timings.
