VFR 1000R Motor just dies

I think that what we figure out is rust in the tank is the problem and it was/is clogging the tank so fuel won't flow to the system. A good tank cleaning maybe the best way to go. I don't know if I want to try acid in my tank as it may eat up orings and other stuff as well. So if you can get clean your tank and get a good rust inhibitor during the winter months this maybe not happen again. Or replace the tank and use a rust inhibitor so it won't start. I wonder why with all the metals out there that don't rust they would use one that does so readily? Maybe its cost alone. But plastic would work too and that can't be that much more that stainless steal or aluminum.

 

if it's a high mileage bike, most likely you're pulse generators are going bad.
when they're old, they work until they heat up then just quit - that explains why you're feeling it running on only two cyl. etc. Five miles sounds about right for the temp to get up too.

they're about $90 from Honda and fairly simple to do. you'll need a gasket too

Hi guys!

Finally an update on the recalcitrant VFR700 and the problem with it dying after about 4-5miles.
It came out of the mechanics' shop in June (after trying replacement cdi, pulse generators) - then immediately went into an auto electrician.
I have just been informed by them that they have tested the systems and replaced the pulse generators.
All indications are that this was the problem, as suggested right here!
Many thanks for the advice on the issue and I will keep you posted to see if she is really fixed! I will be doing a bit of fairing repair work caused by sitting in a workshop for five months, and then hitting the road!

 

That will teach you not to listen to us! Just kidding, glad to hear that you back up and running again.

 

:biggrin:
I did listen... and passed the ideas (even printed off the thread) to the mechanic.

Solution: Change mechanic.

 

hello, i am resurrecting this thread. i just got an 86 vf1000r interceptor and it may be doing the same thing. it has tags from 95 on it still. i new the carbs were clogged because we started it and it was running like ass. it was running on one cylinder ok 2 cylinders were flooding and the other was not getting fuel at all. it would cut in and out and then die and wouldn't restart. run for 2 minutes tops. i removed carbs to find old dried up gas. cleaned all of that blew through everything and tried to crank it today. it will start and idle with choke on but as soon as i try to rev it, it just dies. the fuel pump it working. there is not much fuel in tank, maybe a gallon at the most but pump is pumping but i still don't think it's pumping enough. it will not come out of tank by gravity. i went to dump gas out and when i did there was something in the tank. it looked like 5 lbs. of iron ore, like somebody put it in there. started chopping it up with a pic and dumping it out. is this old gas. i still need to replace filter. i have been reading where i can just do away with pump. i think i will do that but i need to find out what to do with the tank. i was hoping the acid will help me out. after i do that i am going to fill tank to top and see if the gas will come out by gravity alone. spark is great and so is compression. does this sound about what you both experienced. thanks.

 

Wow, crazy if it where me, I'd be looking for a new tank while I was cleaning that one all out, and yes you need the pump. also while at it get a new filter. GL

 

you should really clean that tank out good before getting it back together. i'd pull the petcock off and check that. check out this stuff: Rusteco & GreaseMaster it's expensive but it will clean all rust out of the tank + treat the metal so it'll be like new. at the very least, i'd fill the tank with simple green and let it soak, shake it up and rinse it out a few times, then blow it out with an air compressor to get everything out. and yeah, use a fuel filter too.

cheers,
chris

 

i already got it going and riding it. had the tank cleaned, i put a working fuel pump from auto store on it, with filter and plugs. after cleaning the carb first this thing rocks on the street. what kind of oil does it take though and how much. i just put some auto oil in it for initial startup and ride cuz it was full of gas. i wanted to flush it a little.

 

No kidding, you use automotive oil? well guess it's better than nothing, hope you haven't go to far on it. yea be good for cleaning, but after that, get it out asap as in now! Oil for motorcycles is not the same for autos, as oil for 4 stroke motorcycles have a different shear valve and is used in tranny and clutch. If on a budget get some Honda pro black cap 10-40, if you want the best IMO get the Amsoil Hypo for motorcycles. Make sure you change out the filter too.. good to hear it's on the road, those are a nice machines.

 

ok here is my question

bike needs carbs done I know milage really is bad 25 ish, but at stop lights or at idle is you shake the bike side to side after long rides flexing the leg muscles the bike will die, starts right up no other issues.

Any ideas?

 

when you shake it, the floats goes up and it runs a little rich. adjust floats down
