fuel leaking through petcock

[Guest]

I did a carb rebuild and petcock rebuild on 79 GS850L. Fuel is going right through petcock with lever in all positions. It's like the little spring is not strong enough to push the valve closed or the oring is not seating properly in the petcock. The seating area does look a little pitted. Maybe i should have just spent the extra money and bought whole new petcock. Maybe i can try smoothing valve seat with Dremmel tool?

Should have spent the extra money and replaced the petcock.

Purchase a new petcock

You will probably need to get a new petcock,but there is no reason not to try to make the one you have work,if you've got some time on your hands.

Remove petcock from tank and measure centerline spacing of mounting bolts- 44 mm is very common, but most have fuel and vac outlets facing towards rear- does yours face frontwards instead ?

If you do choose to get a new one, do yourself a favor and get OEM.

Personally, I think the OEM 's are made in same Japan factory as ones' offered by Z1 and Georgefix- the latter sent me a $45 petcock that works perfectly (and appears to be duplicate of original); why pay suzuki dealer markup ?

I agree regarding Georgefix I've never tried one from Z1. I have two from him and they are identical. { and half the price }
