Petcock rebuild kit question

[Darin Jordan]

I had issues with a good quality petcock kit, but I figured out what the problem was.... the metal center piece in the diaphram had the center "flexed" the opposite direction... not allowing the o-ring in the center to make contact with the recess in the petcock body.

I put it on top of an appropriate sized socket, and gave the center a light tap with punch and hammer, checked fitment, adjusted a tad more, and boom... everything works perfectly.

I agree with others... the quality of the kits can vary, but if you pay attention and pre-fit the parts, they can be made to work well.

I got a new petcock from Z1. Works well. Wasnt too expensive.

has anyone here ever gotten the K&L rebuild kit? I just ordered from the bandit, after reading this thread I fear buyers remorse coming on
a new K&L petcock is fairly cheap for my model, I just wanted the satisfaction of wrenching my own!

I believe that's the one I used... It didn't work when I first got it, but I figured out why and fixed it and now it works great.

The problem was that the metal center section on the diaphragm that houses the o-ringed plug that controls fuel-flow was deflected "backwards" (hard to describe this, but I'll try...).... When at rest, the center plug and o-ring were NOT making contact with the petcock housing.

The solution was to lay the diaphragm on a large socket that just rests around the outer edge of the metal section, and use a small drift punch and hammer to gently deflect the metal the appropriate direction.

After a little test fitting and careful adjustment, everything works perfectly, and has for about a year now...

Hi, I just got a petcock rebuild kit of Ebay. It was perfect and was exactly what I needed. No leaks now. Not sure what co. it was but they had the model no. for my bike which is a 79 gs400. or so it says on the bike, im starting to think its a 78 from some of the research ive done.
Hope this helps,
Woody

just got my K&L kit today, says it's for '83-'85 gs1150 (not my bike, at all) did the petcock essentially remain the same or was I sent the wrong part?
