DR650 Petcock Issues

[dflow]

Has anyone else found that the stock petcock does not shut off the fuel flow when bike is off? This has been the case with mine since I got it last year with 900 miles, now at 12K. I have dismantled it twice now to look for issues but all looks good, or should I say as intended by design. I would hate to let it go until an issue with the float needle causes a floading of the engine. A friend had this very thing occure to him this spring. Any fixes known to make the damn thing work like it should in the first place, and I don't mean after market replacement.

Mine did the same thing for a while but then mysteriously 'fixed itself' before I got a chance to take it apart to see what was wrong. Works fine last time I checked.

I have had two suzukis with the vacuum activated petcock and both I had apart numerous times finally got fed up and bought a pingel petcock from keintech.

I'm always amazed when OEM parts perform so pourly.

Just replaced mine with a Pingel. Didn't want to mess with the stock one, what with all the failures reported.

[dflow]

How much did you pay for the Pingel and will it fit to any of the aftermarket tanks? If I go that route I want to anticipate the possibility of switching to a larger tank some day.

Got mine from www.kientech.com

Jesse will want to know if it is going on a steel or plastic tank so he can supply the proper fitment stuff.

I will be ordering another when I do the Safari tank so both will be Pingels.

I paid over $80 for the Pingle for my DR350 on a Clarke tank. Works well but I wish I knew about these other options.

These are DR350 options but it should work for the 650 too.

I just reread your post. I never shut off my petcock, IMO I feel it is best to always have fuel in your fuel system. Prevents hoses & seals from drying out, again IMO.

I had a bad one from the get go when my bike was brand new 650 last July.

I think you need to look into this. I believe that your point of view could lead you into filling the cylinder with fuel should a float needle failure occure. You do need a petcock that shuts off the fuel flow positively. Hydro-lock can be very expensive.

Thanks for the OEM alternatives. You may want to rethink your concept. The fuel system is still filled with fuel if you turn off the valve but without the fluid pressure to cause issues.

'IMO' like I said.

Hope things work out for you.
