Starving and Flooding
05/19/20 at 22:05:38

Hey guys,

This is my first motorcycle in my life so I’m learning quite a bit. I’m from Wasaga Beach ON Canada. Bought a 2001 Savage LS650 not too long ago.
There is a shut off valve on the fuel line between the petcock and the carb, I’m guessing someone put it on there because of underlying issues? See picture. When riding the bike it seems to be starving, I’d give it gas and it seems like it just doesn’t want to go. And if I forget to turn that valve off the bike foods and it’s hard to start (if I take the air filter out I can smell gas on it) also, bike backfires seems like when changing gears?? There is an aftermarket exhaust on it.
I’m a pretty handy guy just don’t really know where to start.

You have a faulty petcock and they put that valve in there as a stopgap.

You should get a new petcock and hose. You can put a new stock petcock on there but it will eventually fail. That's why most of us switch to a Yamaha Raptor petcock. It's not vacuum operated and it won't fail, but you do have to plug the vacuum line from the carb.

Don't buy your petcock from eBay or Amazon. Too many knock offs. You want to get OEM hose too. I would go to Partzilla.com or a similar site and get all OEM stuff.

Lastly, while that petcock is dumping fuel into your carb, it may also be overflowing into your airbox and may have filled your crankcase with fuel. Check your oil and change it if needed. You don't want to toast a set of rings or seize a piston.

Then I remembered I was in RSD and not The Café. Great advice here so far, and you may also want to clean the carb while you're taking care of everything.

There is not many sites in Canada that have this stuff and shipping from the US can be crazy expensive sometimes (especially with the high exchange rate right now)

I wouldn't open the carb just yet. Tackle one thing at a time. Assume the carb is good for now. Replace the petcock and fuel line first. Don't forget to plug the vacuum line going to the carb. See if it fixes the problem.

If it still floods, you might have a sticky float valve. If so, tap the carb a few times with a screwdriver handle and see if that gets it moving again.

6.5 ? you sure that's the right hose?

I think it should be 8mm or 5/16"

----------------

That's the OEM hose for the lS650. They send you about a foot. Not cheap, but it's enough to do a couple of bikes and it's a bit nicer than the crap they sell at NAPA.
