I have a 1994 Kawasaki Vulcan 88. Accelerate off idle and it shakes bad, continues through the rpm range until its a vibration, plugs don't look bad, carbs cleaned, it only has 15,300 miles on it.


Hi, Jim and the usual suspects are:
1. Wheels and or tires worn or damaged.
2. Engine/transmission/vehicle not aligned properly.
3. Primary chain is badly worn or links too tight as a result of insufficient lubrication or misalignment.
4. Engine to transmission mounting bolts loose.
5. Upper engine mounting bracket loose.
6. Ignition timing incorrect due to a poorly tuned engine.
7. Internal engine problem flywheels have shifted.
8. Broken frame.
9. Stabilizer links worn or loose.
10. Rubber mounts loose or worn.
11. Rear fork pivot shaft nuts loose.
12. Front engine mounting bolts loose.

Need radator for kawasaki vn 1500 classic tourer 2001 is the driffter the same radator as the vn 1500 classic plz hellllllllllllp


TO ALL VN1500 OWNERS....This once happen to me,
I went to the garage to start the bike "Nothing ""The first thing is the lights are bright but no turning over,Next you think the solenoid is kaput but the answer was very simple and the fix takes 30 seconds..
Do not take the bike to bits looking for other problems and look at the clutch leaver and you will see some wires going into a plastic shroud going into the switch in the clutch leaver, Make sure this has not popped out if its connection as it some times may do after a few years due to constant turning on the handlebars,
When this is not connected you will have a bike that will not fire up but comes alive and you will hear a clicking noise but this is from the engine carb area and every function of the bike will work but it will not turn over, Worth looking at and saves sixteen quid for a starter unit you never needed.

Vulcan 1993 750 backfire issue everytime i let off


This is often caused by an air leak , inlet manifolds, exhaust gaskets into the head or the gaskets between the headers and muffler.
This is assuming all the rest of the bike is set correctly, valve clearances,airfilter, clean carbs

Engine missing,backfires, runs rich, replaced old gas


Replaced old gas then i am assuming the bike was not used for some length of time? If you have old gas in the tank and the bike was not used the gas in the carbs would have gummed up the jets in the carb or carbs.
sounds like its time for the carbs to be cleaned.

My vulcan 1500 1997 back fire somme time wy


lean gas mixture. or the valve timing is off, but probably both. A lean mix will run really hot and allow for secondary combustion in the pipes (backfire) when the valves let even a bit of uncombusted gas through. My guess is that the bike hasn't had the carbs cleaned out thoroughly in a while. Run a half can of Sea Foam with your full tank of gas to help clean out the carbs, but really you should take them apart and dip them to clean everything out. Also you could adjust your pilot screw settings to make it run a bit more rich, but then you are just compensating for the dirty carbs. That's just my guess.

1995 vulcan 800 gas comin out carb intake


This sounds like a carb float being stuck open. Turn off the gas and drain the offending carb. Next, turn the gas back on and sharply tap the float bowl with the plastic handle of a screwdriver as the fuel bowl refills. The goal here is to vibrate the float to free it up. If doing this process a couple of times does not free the float I would remove the carb and clean it with a spray carb cleaner. Pay special attention to the float needle. Clean the air filter then re-mount carb. Next Remove the water trap bowl at the bottom of the petcock, (gas valve). Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ). Now would be a good time to install an in-line fuel filter if you don't already have one.

Install new stock spark plugs AFTER you make sure that the bad cylinder is getting spark. Be sure to balance and sync the carbs when finished.

Please rate this solution as " FixYa " if all goes well. Thanks
