Vfr Gas In Oil

A few weeks ago I checked my oil after my 94 vfr sat for a few cold weeks. After pulling the dipstick out oil and loads of gas come flowing out everywhere and the gas tank all but empty. I had no idea what could have caused this. I changed the oil twice to make sure no gas was left in the crankcase. Iv been running it for the past couple weeks to see if it continued to do it and not for the past day or two I can smell gas on the dip stick. My tank hasn't dumped gas down through again but I am still concerned with the smell of gas. I am thinking maybe a bad float needle in the carb? Bad piston rings? I don't really know, but one thing to note; the bike is running quite rich at the time and needs re-jetted. Please help! Thanks.

 

float needles? I wouldnt ride the bike until you sort oot your problem.

 

Yes, what do you think is causing this? What should I replace first to fix the problem?

 

Seven thing happened to me while I was riding back from Vegas. But in my case the stupid fuel pressure regular had bursted dumping a ton of gas into my motor. About 6.5 qts of oil mixed with gas came out during my oil change.

 

you need a good carb cleaning to fix the float needle issue, likely debris or varnish especially if the bike has sat for a while with fuel in the carbs.

I just recently began work to get a '97 back on the roaD again after 9 years in storage and learned that it's easy to turn the petcock on or off with a long screwdriver. Just remove seat, no need to get your hand in there, which requires removal of tail plastic for access room.

 

I was thinking aboot a leaking petcock, but re-thought it as it would be leaking from the unit itself possibly from my past experiences. I have a twin with a pingel pet cock, it has ON/OFF and when ever I get off the bike, I switch it off.

With this theory in mind, if your needles are leaking, you could turn off your petcock and thus they wont leak at least when the bike is sitting still. But, in my mind, as soon as you turn it to the ON position and hit the button, the bowls will over flow because of your needles being rubbish.

I got a new one (petcock) for my 91 that is sitting on my tool box as yet to be installed. 93 someone was thoughtful enough to install a new one, the old tank was trash though and I ended up buying a new one. Anyway, get new OEM float needles and a gasket kit, it wont be cheap. :thumbsup:

Yeah unfortunately won't be cheap but I do plan on cleaning the carbs and possibly re-jet. While I have it all apart I'd be stupid if I didn't replace the OEM float needles. I appreciate the help ridervfr!

 

Needles, floats, crud/varnish on everything.

I have a twinstar cm200t and learned the hard way about crap gas. Forced a major cleaning that could have been avoided. The bike holds 4 quarts of oil, but when 10 or so came out I had pretty much the same feeling of frustration. Wasnt two weeks later the paper seal between the halves let go and dumped half the oil at work in the parking lot. Good news for you, honda stopped using straight paper in the late 80's so it shouldnt leak on you.

If it does, sell it as a honda BSA special

 

Invest in one of those cans from Gunk, its a soak can and comes with a basket, I did this with my latest project. I soaked the bowls, and all the brass jets for a day or so. The set-up is 20 dollars or so, but you only live once and the end results is worth it. I have used sand blasters in the past but that was when there was one where I was working.

You need to get two seperate kits from Honda, one consists of bowl gaskets and assorted o-rings. The other kit is more important as you may be able to rig up a bowl gasket but won't be able to improvise needle/seat. This kit has a new needle along with the brass seat/crush washer and little strainer (only honda could come up with this chit.) Anyway, take your time and have a nice place to lay oot your work, dont mix up the diaphrams and springs, they go back home to each carburetor you took them oot of. I had to adjust the float level on my bike as some monkey was in there, (she was violated!) I would not mess with increase jetting or shimming needles as the bike rides fine with the stock set up. 130 main jets me thinks. Carb cleaner, some stripped wire/guitar wire/compressed air/tooth brush/q-tips. You get the picture, I got a K&L jet pick that is nice, the various wires fold oot and are housed in a metal case. Cheers and pictures do you good.
