Hose sizes

What's the inside diameter of the fuel line from the petcock to the carb assembly?
Now for the overflows, what kind and size hose do I need? will a fuel line do?
And same question for the vacuum lines: size and kind.
If I read correctly, the overflow hoses must route the fuel away from a hot engine in the event of an overflow, so the hoses should be routed towards the rear of the bike. Isn't this wrong? Is the fuel not going to spit out in font of the back tire? Maybe someone has a picture I can base myself on.
And as for the vent lines, I guess they should be routed up, somewhere under the seat I assume, since I don't have the original airbox?
Any advice is good advice!
While I have your attention, I'm still looking for that seat lock (Kawasaki Part Number 27016-5010)!

Dont know if this will work for you but check it out.
For fuel line I suspect you should have 1/4 inch ID but best wait for someone with a 650 to chime in.
The overflow is probably like mine - a smaller ID.
Good luck.

What your saying about the overflow lines makes all the sense in the world but where else are you gonna route them to? In the 28 years I've owned my bike it's only dribbled out those lines twice and both were at idle before a ride.

The fuel line is metric, 7mm I think. But I found that 5/16" I.D. works great.

ditto...5/16" clear with a clamp on each end. Some say clear is best to view fuel flow if needed, but I prefer to use clear blue cuz I think it looks coolB)
The overflow tubes get threaded thru a rubber loop that is located on the right side close to the swingarm. It holds them all together and keeps them from floppin' in the breeze:) But I have also seen them just lopped over the swingarm as well. The vent lines can be routed thru the same loop as well. Don't route them upward as foreign crap can get in them and make their way down to the carbs.
Maybe others have more ideas for you if you don't have that loop.

Correct me if I'm wrong,but it seems to me that if you have TWO lines feeding the carbs,then the I'D. is 1/4 inch,and if you have ONE line,it's 5/16.

Sandy, I've heard of you big block guys using some kind of a "T" or something? The 1000's have dual inlets? All the 650's just have the one line.

Well when I was running the stock carbs,John(26's)there were two 1/4" lines feeding the carbs(factory dual outlet petcock),but then I switched to the 29's,which only had one inlet(5/16 size).I didn't want to mess around with adapting the petcock outlets to one,and a different size to boot,so for more reasons than one,I purchased a Pingel "High-Flow" petcock,which is a single 5/16" outlet.
It feeds the needs beautifully!:laugh:
