I searched through the forums here and found that the likely culprit is a faluty petcock. My question is can I rebuild it effectively or is it worth it to just get a new one. I have no idea what year the LT80 is so does anyone know if the petcock was the same on all years? Also, any leads on where to get a petcock would be helpful. I found one on eFence (ebay) for around $50 but there is still a few days to go and I need it now.

Thoughts???

A Banshee petcock will go in it's place also. A lot of guys go with the aftermarket pingle, so keep an eye out for those too. You would need to plug the line for the vacuum pulse feed from the carb, then you will have a regular petcock to deal with.

 

Get the shee petcock.
Much cheaper!

 

You might want to replace the needle valve in the carb. That's what sounds like the problem is to me.

Yep!!! I'm using the Banshee petcock and works great. If you feel you have to go with the oem Suzuki one,
check the adds in the back Dirt Wheels. I bought a new one thru "MR Cycles" (800) 359-0567 for just under $50.00

 

I agree with coyoteman.If its filling the cylinder with the petcock closed you need one of those as well but it shouldn't fill up the cylinder even with the petcock in the open position if the needle and seat are doing their jobs.

 

FYI::
There was a lenghty thread on this. maybe you could find it. Good info.
Basically what is happening here is the petcock is bad and the hydraulic weight of the fuel is pushing thru the needle.
This happens on any other machine, that's why there are on/off positions. The LT80's petcock is vaccum operated and on is off when the motor is not running, thus having a weak spot.

 

SonicDeath, Check out the thread I found for you. Maybe it will help.

And, Welcome to the forum[img]i/expressions/face-icon-small-smile.gif[/img]

 

Well, I won't argue with you on this subject, you have helped me as well as many others with LT80 problems, I respect your opinion. But I will say I was having the same problem with the cylinder filling up with gas and replaced the needle valve - now I don't have that problem.

 

Thanks for the help guys. Just an update: I ordered a new Banshee petcock and carburetor rebuild kit, should get them next week. I also ordered the blocking plate for the oil injector so I can remove it. The injector hasn't worked in a while and I have been running pre-mix in it any way. Besides I ride a 1999 YZ 250 so pre-mix isn't a problem. Riding season is coming on strong here in Southern California and my daughter is bugging the crap outa me to get her beloved LT80 fixed. Thanks again for the help.
