    Leaking petcock

    Is this a rebuildable part? If so, any pointers would be helpful.

    The problem is that the inset is a cork cylinder. Blue Moon use to sell them but I think that whoever was making the cork stopped. Try contacting Blue Moon.

    I think they can be rebuilt. I have seen info to that end.

    If anyone on the planet would know, it would be Craig Vechorik.

    Vech has an article on his website about the Everbest petcock...I believe that is the type of petcock in the picture...

    Is that for a single?

    The "Neverbest" petcock was never intended to be rebuilt, but persistant people have managed it. The one on my R60/2 was rebuilt by a guy in Canada, and so long as I flip it to open and reserve every couple weeks or so, so that it doesn't dry out, it's fine.

    The one that came on my R51/3 was great. Never leaked, no matter how much I ignored it. Then I was in an accident on the bike and it took a year and a half to put it back together. So, I removed the petcock and put it in a jar of gasoline. At the end of the resto, I pulled it out and mounted it on the tank. I put some gas in the tank and it started coming out of the petcock almost as fast as I was putting it in. I almost cried.

    Now I've got some repop version of an earlier petcock on the bike, and I've managed to disassemble the Neverbest. I have to go hunt up some cork or gasket material that's the right thickness and try to put it together again, but I have my doubts.

    Thanks for the suggestions! I'll probably pull it apart later today. It is intended for my R27 which has a perfectly good later type petcock on it presently. I ordered a carb kit and top end gaskets for the R27 last friday, and will wheel it up to the work station as soon as the space is free. Right now I am pulling my hair out with a slow rolling electric start on one of my 750 airheads, and a front tire that refuses to seat on the other 750. That leaves me with only a battered Honda XL250 in serviceable condition.

    this is un-accceptable...
