"Where Do These Hoses Go" updated pics?

Photobucket has unfortunately stopped hosting the photos on this page...

Anyone able to get some pics of theirs to update it with? Personally I'm looking for some help figuring out where to route the hoses on VM carbs.

I've got the vacuum line on the 3rd carb attached to the petcock but I'm a little lost on the rest.

Fuel feed to the petcock, obviously.

The only other things are the float bowl vents. Attach a piece of hose to the two nipples, and run the hoses up to a safe place on top of the airbox or similar, so they can breathe safe.

Thanks for that, Rich.

Thanks y'all I was worried they were vacuum inlets like carb 3's and was gonna block them off. Glad I didn't.

Where should the overflow tubes end up? If I remember right, they originally went back below the rear master cylinder, but looking there now it seems like that's awfully close to the exhaust for a fuel overflow! Any pics or advice is appreciated

From what I recal of my original fuel vent hoses, they were bundled together and exited just ahead of the rear wheel. They would have been down between the original side pipes and well away from them.
Which doesn't seem all that sensible, getting a gush of fuel on the rubber, in a bend.

Yeah... I doesn't seem like there's a great spot for them. It's either over the exhaust, near the chain, or in front of the tire. Am I wrong to be nervous about not having them on at all? Fuel leaking on an air cooled engine also seems like it could be trouble.

I don't know about the 8V engines, but the 16v engines have a chase, a square hole really, formed into the right rear of the engine case. Through it, we run the battery drain tube, the fuel tank level sender drain tube, and the air filter plenum oil drain tube. (the CV carbs don't have bowl drain tubes). It puts all of these potential drippers off of the tire axis and safely away from the exhaust. Maybe the 8V engines don't have this?

Yeah I'm not seeing that on my 8V. I did figure out that the foot peg bolts are threaded all the way through, so I'm thinking I'll bend some wire and give them a good loop to thread through that's a little further from the exhaust and not in front of the rear wheel.

Alright I got around to bending up some brackets using metal coat hangers. I've attached the brackets to the back of the foot peg bolts and the muffler mount, so that they avoid the real master cylinder and brake light switch spring and terminate about half way between the muffler and the tire.

Nice work! And.............you solved a problem that hasn't been a problem since that bike was new!

I've never heard of a bike catching on fire, or anyone losing rear wheel control from those hoses running to the back of the engine like the Suzuki engineers designed!

If you have that much fuel coming out of them, you have bigger problems!

Yeah I'm probably a little paranoid about it but if I'm gonna do it I might as well do it right
