still having problems !!!!! need petcock to

I have a vf500 86 and Its like the clutch wont let go. I can shift but the wheels still moves (the bike is elevated and the clutch is grabbed) and if I let go nothing happens. Its there some sort of adjustment I can do I did really find anything in the repair book?also I think that my valve on my gas tank is bad cause I took the tank off (it wouldnet start.) And used a funnel with a hose and poured gas down it and the bike runs great starts right up but when I use the tank it wont even start.

 

If you have the rear wheel up, it's normal for clutch friction to spin the wheel even if in neutral and even if you have the clutch squeezed........normal.

 

no its not !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!...:crazy:tire should stay still maybe move a little from vibration..you may need new springs. unfortunately sometimes you may recieve answers from drug induced people.. if the bike is pulling with clutch in it needs adjustment clutch in in gear should be able to hold it wide open without it pulling at all...good luck

 

ok can I adjust the clutch myself or does it have to have special tools?

 

I am with Squirrelman on this one. When the rear wheel is up it will often spin even when its in neutral and even when its in gear with the clutch pulled in! eddie

 

ok well when I hold the clutch and give it gas it moves like I am in gear with the clutch out (but I am holding the clutch in and watching the wheel move)?

 

Does it act the same, with the wheel on the ground? When a clutch is cold,it tends to be a bit sticky and this causes the wheel to spin, when it is raised. Try it again after it is warmed up and you'll notice that it doesn't spin.

 

If your suspended rear tire isn't spinning from the light friction of the clutch when it's pulled in or in neutral even, then when you're under heavy load(acceleration) you'll slip from not enough pressure on the clutch plates.

 

when the rear tire is not elevated it just dies like I popped the clutch and didnt give it gas.

 

Always thought he had his head up his exhaust pipe.....it's OK to be dumb when you're young, but he's not.

New springs?? Just what would new springs accomplish, eh??

(Stick to your apron, spatula and recipies for Beer-battered Southern-fried possum with Jack Daniels glaze....You're more useful in the kitchen than in the garage.)

 

It dies when you let the clutch out while in neutral with the tire on the ground??? What's your idle rpm set at? Have you checked the clutch out internally?

 

no If I hold the clutch and shift into first it jerks forward and dies (all while the clutch is held in) If I were to lift the back tire up and do the same thing it would just spin then I could shift into second third and fourth all while I hold the clutch in never letting go of it and the wheel continues to get faster!

 

Hi Gang,
a bit of basic fault finding can be tricky when not there in person. I don't profess to be an '86 wizard of any sort.
It's definitely trying to drive and not stalling from a dodgy side stand switch (if Fitted)?
The clutch is hydraulically operated:-
Check for leaking fluid under pressure with lever pulled.
Clutch lever is not bent so as to restrict full rearward movement.
Fluid is replaced with clean, good quality brand.
If lever is adjustable, adjust it out so full travel is used to bleed M/cylinder all the way down to nipple at clutch. (Tube into a jam jar with fluid in it).
The rear wheel will drag with the back end off the ground but with the rear brake on the clutch should still hold.
Next thing to look for is if the slave cylinder is working as it should.
Best of luck.

 

I have done all that already !

 

Have you checked the clutch itself yet? Plates/springs/basket?


What about the rod(I forget what it's called) that goes from the slave cylinder to the basket?

 

Dude

"I have done that already thank you."

I know how it feels to be frustrated but being nice is better than dressing well.

 

man......I hate say this...........but I'm with squirrel on ths one...however in lite of new evidence... have you bleed out the system? I know it sounds stupid, but I had an air bubble in mine for a long time ....once it burped the system worked fine... you also want to mae sure you have enough oil in the bike..... How do the gears shift? does it grind when you put it in gear or does it jsut clunk? hot or cold engine? does it do it in any other gear? How about if you try starting it in gear holding the clutch in?..
after you get a good bleed try all those things then report back and we will move forward.

by the way, Squirrelman may be old and crazy but I would listen to just about all he says about your bike...but don't listen to him when he goes on a rant about anything older than an 86...(he doesn't like them):crazy:

lastly don't worry, you'll get it

good luck...

Well last weekend i put three quarts of new oil in and the gears shift great. this is the best way to describe the issue.Its like the clutch wont release (disengage), I can hold it in and shift and bike will move while I am holding the clutch still. It does it in any gear. Its like the clutch is to far in and wont let lose when I pull the clutch bar on the handle. If I start the bike in neutral and then pull the clutch then shift to first the bike jerks alittle and then dies. I am thinking that the clutch needs to be adjusted somehow?

 

Well, altho squirrel has professed his dislikes for the gen 1, this bike we are talking about is also a gen 1. The 86 500 is a first gen.
My gen 1 ( 85 700 ) does exactly what squirrel said ( it spins the wheel from friction very slow when in nuetral while on center stand )
I dont know about the other issue with your clutch or hydraulic system, but it dying with the clutch pulled in after shifting into gear is _not_ realted to the slow spin in nuetral, if it is not normal, it is normal on our gen 1's
No offense to anyone, just veryfing what my bike does.
:thumbsup:

 

Back to top..............

there is no "adjustment" on a hydraulic clutch.

your clutch hydraulics are not working.

You have 2 components: the master cylinder (up top) and the slave (down low), and one is not working right.

It's possible but less likely that the problem is inside the actual clutch ( plates & basket) itself.

you can buy seal kits to easily rebuild either mc or slave so that you generate enough hydraulic pressure to release clutch.



very importamt question: when is the last time the bike was ridden on the street and the clutch worked normally ????
