$30.00 Suzuki petcock fix
Some might know that Suzuki has a vacuum petcock on many bikes, It is for people who always forget or don't know to turn the fuel off when the bikeis not in use. It is fine until the stupid thing fails and leaks an entire tank of gasoline all over Your floor and causes a fire hazard. I did some research and decided to put it all togethor in one thread to make it easy for any other Suzuki owners or soon to be Suzuki owners.
This is the original ^%$^% petcock The failing point is the rubber diaphragm that is opened by the vacuum port on the carb, And You find out there is no kit for the Dr200SE So after searching for an answer, I found out that a petcock off of a Raptor 660 will fit 30 bucks off ebay, A guy named adventure wrencher who was awesome to deal with. I also grabbed some of the good stuff, You can never have too much of this around Here are the two side by side, You will lose some reserve with this swap Installed on the bike, Fit like a glove. One small issue is that the new petcock is 3/8 line and the carb inlet is 1/4, I clamped the snot out of it and picked up a reducer the next day. And last thing is to cap off the vacuum tube on the carb.... This is a simple project with no actual thought required to do....Kinda lame to post it but I found very little online that explains everything. Hope this helps any other Suzuki lovers out there..........Whoo hoo time to ride.

Thanks for the post. The vacuum port that you plugged off would be a useful tuning aid. I'd be inclined to believe that if you connected a vacuum guage, you could pinpoint the correct air / fuel mixture by observing the highest reading.

I see that you would loose some reserve capacity due to the shorter tube for the main part of the tank. Question, Does the short tube need to be that long? If it was a little shorter would you gain Reserve capacity?

It's not the short reserve tube that determines reserve capacity, it's the long main one. The short reserve tube is a filter that will pull fuel right down to the base of the valve. The shorter version of the long main tube uses more of the available fuel than a longer main tube would. Therefore, there's less reserve available to you when you switch over.

Looking back over the picks I now see the filter screen. I thought it was a tube that drew from the top of it. Makes more sence.

BTW:
1) those $2 GIO Monster fuel tanks come with a similar petcock (it will fit) 2) TNT (those aftermarket folks) will sell you an aftermarket petcock (from Thibault vacuum only, no reserve, for a Yamaha scooter) for $15 3) a 2002 Raptor 50cc, or 80cc, petcock will go, $25 (my local dealer) and it's 1/4 inch. It's a good idea to use fiber washers under the bolt/screw heads. |

Oh I forgot, The reason this one works is the drop of the petcock vs a shorter one. The pinch on the tank will block a shorter one from turning because of where it mounts. Just for anyone who wants to experiment.

Everything I listed uses the same gasket (plastic, or steel tank), they are all interchangeable here, bolt spacing the same. The aftermarket vacuum petcock I just threw in there. I *suspect* that all this stuff is made in China anyway, no matter where you buy it, probably for peanuts, otherwise they would supply kits?

Thanks for posting the helpful thread, AZ! The Raptor 660 fuel petcock looks very much like the Yamaha, TW200 fuel petcock I installed on my Zong's Clarke fuel tank.
