Oh hell,,,, that's your tattle tell hole it's pissin out of. When your water pump deal is shot it pees through there to let you know instead of filling your bottom end full of water.

Super stoked you got her fired up though!!!! I agree, after you run it some it'll get easier and easier to start. You'll learn the sweet spots and all her quirks and will have it down to almost a science.
I didn't have my 500 for long and only rode it once but it was such a pain to start at first simply because I didn't know how to. Then I figured it out and every time it would fire right up. And mine was sitting on an engine that had quite a few races on it.

Still, REAL glad you got her running!! I hope she does you well! And like I said, scope out that water pump seal

Yeah in the one picture you can actually see water fluid coming out. Does this mean I need to rebuild my water pump and replace the seals? I was hoping to avoid having to do this! Dang it!!!

Replace parts 5, 7, 13, 14

Link doesn't take you directly there.  Click on cooling system, OEM parts, water pump.

Ahhhhhh the dreaded water pump. I had mine apart 3 times before it finally stopped leaking. It will probably leak again since I am talking about it.  [|]

Congrats on getting that thing started. This last 10% can be difficult and an ass kicker.  (Y)

I also have an oily like substance leaking from my exhaust flange. And tonight noticed red fluid (I'm using type f tranny fluid which is red) dripping from my engine cases but can't narrow down where it's coming from.

Chris should I get two of the washers and lock washers?

All you probably need to do is grind the end of the water pump shaft off just enough so that the end of the shaft is a few thousands below the surface of the impeller.  The rubber sealing washer should tighten up against the impeller instead of up against the end of the shaft.  Coolant runs under the rubber faced seal washer and coolant runs out of the weep hole.

Ill probably just order all the seals and washers new Jerry, I'm not that great at grinding stuff. Can I ask your opinion if you think all that oil and fuel I left sit in my crank case could be a reason my bike is so difficult to start?

Replace the impeller if you are not willing to grind the end of the water pump shaft if the shaft protrudes above the washer sealing surface on the impeller

The engine cannot run if it is flooded with fuel and oil.

Remove the spark plug, turn the ignition switch OFF, turn the fuel off,  put it in 1st gear, hold the throttle wide open, then push it as fast as you can for about 30 to 50 feet.

If it is loaded up, you will see vapor coming out of the spark plug hole when you are pushing it.

My luck is so much more awesomer than your luck its ridiculous!! So tried pull starting the Zilla Thursday wouldn't run. Got it back in the shop and tried kicking it a few times and it wouldn't kick over it would go over then hit a hard spot then stop. I was tired I said eff it ill figure it out later. So today I go to the shop couple primer kicks its cycling over just fine tdc and hammer it over hits a hard spot and stops. Get off look at the motor and this is what I find...

Broken motor mount, **** open stator cover, sheared flywheel key and flywheel has striped out the retainer nut and spun free which is what smashed the cover.

Is 1/4" thick aluminum thick enough for motor mounts?

You would think so.Stupid question but you sure you have the spacers right side to side?2 shorter ones go on 1 side,2 slightly longer on the other.

Welcome to the joys of owning a suzuki,,, something breaks when you run it. You ran yours once and it broke everything like it did. Run it again and the frame shears. Run it a third time and the swingarm blows out (wut?) Lol

Man you have some amazing luck! Can i have some of it? No? Ok, i wouldnt wanna skeef any from you anyway

If you look closely you,ll see 2 are a tad longer.Just put mine together and I think the shorter 2 go on the clutch side...You,d think I,d remember but it was on a long weekend.If you mix them up I think it could cause your mounts to break due to the twist.Aluminum doesn,t like to bend like steel,it breaks.
