Sorry.
It's like it's attempting to run but it's not catching. Like the revving of a car that won't start. Ive always heard it phrased "not turning over". Idk which better fits your description but its that sputtering sound when you turn the key but the car doesn't start.

It was running for a few moments this morning but as soon as i got off it quietly died.

When you installed the petcock you did remove the protective sleeve? normally plastic tubing over the filter. shoot some more either, it may be just hard starting.

If not, i didn't see any additional plastic covering it...

I disassembled again really quickly and didn't see any plastic covering. Did notice that i had dropped the oring for the speedocable into my frame. I thought i had yest. I put it back on, gave her a spritz of starting spray and she started up. This bike is always giving me many heart attacks. Thanks.

The real Yamaha petcock has a brass tube with a single expanded bulge at the end.

Took it around the block and came back. Let out a nasty backfire when i shut it off. That can be adjusted with the idle mix screw, right? When i put it back in i turned it all the way in clockwise then back out 3 full turns ccw, and back 1.5 clockwise.

Take a look at serowbots carb tuning thread for instructions on adjusting the idle mixture screw.
You started with at the max then adjusted it to the min... for the resulting kerpow.
maybe the max setting was why you had a hard time starting?
in other words, adjust it to idle best, not just a number.

Hey,
Just pulled my oil filter. It is completely saturated but the o rings still look good.
I havent adjusted the idle mix yet. Had a hard start this morning and had to spray starting fluid again. None of the auto stores have the kn filter i need. Didnt trust using an offbrand.
Should i trash the fil ter? It is not at all red like tge ine in the pic

There is nothing wrong with using a "HiFlo" filter. They can be had for fairly cheap. Believe it or not, I often found them cheapest at a dealer or local small parts shop. Both had free shipping and competitive prices to online. Sometimes they are cheaper on ebay or Amazon, though. You won't find anything at auto stores like O'Reilly's or AZ. I always inspect my filters during an oil change, and I've never had any problems. The design is very simple and HiFlo's build quality is pretty good. Make sure you install the filter the correct way (!) and that both O-rings are present and accounted for. As for trashing the filter, I personally change my filter at every oil change. Some do every other. With the history of this bike, or at least what we know of it, I would definitely change it. Just my $0.02.

Get the filter that suits you. Here is a sale for 3 HiFlo filters at $5.87/ea after shipping.

And here is the K&N variant for $6.67. http://www.amazon.com/KN-137-Suzuki-High-Performance-Filter/dp/B000E28COK/ref...

Both will do the job.

I guess that means I'm no good anymore; I've got 4 more cylinders! '08 Yamaha FJR1300 and still '01 Savage
