Won't Start

new z1 petcock was leaking?

so was that a new z1 petcock that was leaking?

Found out the petcock is leaking fuel, the gasket is leaking. I have not had a lot of time to work on it with the holidays. I really need to rebuild the carbs.

Anyone around Cincinnati this weekend?

Sounds like the carbs need cleaned.

Yup. I don't see any alternative.

I put on the tank from Ebay. I received my new petcock from Z1 in the mail. The petcock was not the right one. The fuel and vaccum nipples are on the opposite side of the original one, so that sucked. But I took the gasket and diaphram from the new one and put it on the old one. Seems to be okay.

I got the bike running for about 3 minutes. I put gas in it. Held the choke wide open and it fired up! But if I let go of choke, it would die. White smoke was coming from the exhaust heavily, on one the left exhaust more than the right. After the first minute of running, it died. I held it full choke open again then it would die after 20 seconds.

The battery is bad to, had to use a jumper to power the battery.

Still working on getting the choke cable connected. The "new" gas tank should be here on Thursday . I am going to pick up the petcock as well. Weeee!

Sometimes studying the parts fische is more instructive than the manual for things like a choke cable. The manual will probably assume you already know how to do it. Its more difficult when its missing altogether.

It cranks slowly. I don't have a battery tender. Going to pick one up tomorrow. I just got my choke cable in the mail as well. Having some issues hooking it up though.

I plan on draining the fuel out of the carbs and putting fresh oil and plugs in tomorrow, then seeing if she will turn over.

I don't understand what you mean by "tries to crank". does that mean it doesn't crank? cranks slowly? Have you charged the battery? if not, you need to. It should crank over quite quickly. If you look at the carbs from the left, you will see a couplr rods in front of them paralell to the rack of carbs. One rotates when you twist the throttle. The other one actuates the choke. If you pull on it to the left, that turns the choke on. These bikes normally want full choke and no throttle to start from cold. Your bike should have come with a safety switch requiring you to pull in the clutch in order to statr it. If that is still hooked up, you will need to tie it down or have someone hold it for you while you pull the choke rod and push the starter button. The clutch safety switch can easily be disconnected by messing about with wiring inside the headlight. You should probably wait until you have studied the wiring diagram a bit before jumping in there.

The onesZ1 sells will work with his tank. I put one on an 81 650G this summer. Also, they don't come in a Suzuki box, but they are OEM petcocks. Same manufacturer Suzuki used for the small switch units.
It will be correct.

DO NOT get one from Z1 unless it is an OEM vacuum unit. Also, the fit varies between tanks. Make sure you have the tank you are going to use BEFORE you purchase the new petcock. It may be different.

I won the tank for the 81 GS650G! Now the wait begins.

Re-sealed the airbox. Fits nice and snug.

Tried to start it, nothing. The starter sounds pretty bad now, probably from the cold weather and constant starting....sucks.
