Question about 2001 kawasaki VN 800 Vulcan Classic

1 Answer

Bike sat and now wont run right

2001 vulcan classic 800 cvk single carb sat for awhile.
cleaned the carb page by page etc. but the darn thing misses real bad when trying to throttle cold or warm.
?cracked head gasket?
there is some oil on the front cooling head but wouldnt think this is the cause as its been there since i bought the bike.
It seems to idle ok.
I did not see any adjustment screws or anything other than the idle adj. knob below the filter assembly.

    I have been messin with the bike for a short while now and if i pull the choke lever out aprox 3/8 of an inch the bike runs good while sitting still. Is there some kind of adjustment I am missing on the carb or something. I can't believe that i would have to run the bike with the choke out that far for it to run properly.

    The plugs are new, emptied the fuel and put fresh in, checked the float this morn and its good.

  • jfry13 Sep 08, 2009

    yeah i think thats what i am going to do
    tear the carb down and clean it again, mabye i missed something to clean, i did go by the book, but i did not see anything about the air mixture screw. hmm, back to the book, i guess. i'll let ya know

    FINALLY,
    took the carb apart again and cleaned, and cleaned, and cleaned, then when i thought i had cleaned enough, i cleaned it some more. However the bike runs perfect! she warms up and away we go!
    thanks for the advise kevinbulsara!

    if it runs fine with choke half out it must be a carb problem, i dont know the bike , but in most cases there is an air mixture screw , the mixture must be out thats why it runs fine with choke halk on lack of fuel i would have thought, ipresume when u rev it it revs then u put choke in and it pops and bangs then dies i would allso re clean the carb and make sure the jets are clean

Wont idle down


If idle speed control won't bring idle down check intake hoses for leaks. With bike running, spray WD40 onto intake surface near carb and head. If bike slows the problem is there. If smoke comes out of one exhaust, that is the intake that is leaking. re-install carb.
If that dosen't resolve the issue. rebuild carb checking for tears in rubber diaphrams and gaskets.

Probably would not be a bad ideal to have your Kawasaki shop take a look at this motorcycle. With only 77 miles on it, you don't want to risk damaging the motorcycle. There are really limited options for the backyard mechanic in these kinds of problems. The $ you spend will be well worth it.

I have a 01 vulcan 800 classic. i have to manipulate the choke for the bike to run at high speed, or it will start cutting out. at 40 mpg. it will run fne with the choke 1/4 of the way pulled out.


You have the classic symptom of a dirty carb, has the bike been sitting ? What is happening is you are compensating for more fuel by activating the choke, you can try some "Techron" you get it at your local auto parts store its usually in the fuel injector cleaner area, this can sometimes dislodge and clean the jets, if that doesn't work then I would have the carburetor clean properly.

Are the carbs on the us model and the uk model have the same specs.on a kawasaki vn 800 2005


the us bikes are normaly set up to meet the california clean air regulations, as europe have/had no restrictions i would expect the would be jetting differences, prob on the lean side of things for the us bike larger main jet etc, if you find a carb check and see what jets are fitted for main and pilot, also the needle might be set lower..( weaker )

How to clean a carburetor on a 2006 kawasaki vulcan 800.


If the bike is still running your in luck. Just go to your local auto parts store and get a can of Sea Foam and dump about half the can in with a couple gallons of gas. fire it up and let it idle for awhile until it get a good carb full. Then procede to ride it Hard and you should start to feel the results very quickly. I recently revived an old honda that had been setting for 16 years that same way. I just let the Sea Foam set in the carb over night and went riding the next day. ( Old time mechanics secret carb rebuild.0 Its been around for 60 years or so. Have fun.

Bike will only run with choke fully open


I get the feeling you have just pulled this out of winter storage and there was No draining of the carbs or gas stabilizer poured in the tank prior to storage...right? Well you have a classic clogged carbs and idle jets mainly. This will require carb removal and cleaning......Good Luck to you !....Tim
