1999 Monster Won't Start

In your video it sounded like there was hesitation after you hit the starter. I reread your December post and if that is the new battery you will have to charge it fully before trying anything because it is weak. Have you been leaving the bike outside? Has she been rained upon? If so then there is a good chance you have water in your gas. Water in gas can stop you cold and since they are immiscible adding new gas will not help. I would make certain battery is fully charged (or jump it with beetle) then remove air filter and spritz some new gas or starting fluid into carb. If she fires at all then it is probably a fuel problem. If she does not fire pull plug and hold it against the engine while you press starter and look for spark. Then report back.

Works just fine, but with one caveat, hold it tight and don't flinch otherwise you will get a rude awakening. Also works better at night or in the shade. Makes the spark easier to see.

This is how I got my M750 with empty carb bowls to start.

1. Pour a small amount of gas down the intake tubes.

2. Leave the choke closed

3. Hit the starter.

I get the same hesitation, even with a freshly charged battery sometimes, but still make sure you're fully charged.

Got it running by the help of a friend. He flushed the carbs and let them drain. A greenish fluid was in the oil (gas probably) which I don't know how got in there. I know my clutch plate had some small sealing problems but I thought that just let oil condensate on the outside not sure how that is causing gas to get in the carbs. This could have been a old problem from when I fixed my tank and other things and wont return. I guess time will tell.

Thanks for the comments once again fellas.

If it was flooding trying to start, you could have gotten some gas in there that way ~

Did the oil smell like gas?

Drain and change oil quickly before any damage happens to your bearings.

Is that tank propped up with the prop rod, or is it just leaning against it's own weight?
