Carburetor Solved

Thanks for the were on the right track. What hurts is that the problem was my fault.

Before I get into that, a couple of things. I mentioned earlier that I used a plastic semi-funnel to take the gas from the bottom drain to a container. It worked but was hard to keep in place, etc., so I went scouting in my shop and came up with a piece of aluminum angle.

See the end of it right under the float bowl drain, like a letter V ??

It worked perfectly - could even remove the drain plug with it in place and spilled zero gas. Smart Lar.

Now to the problem. Not sure if this was the entire problem, 'cause I did finally get it to run a bit on throttle but it was still very bad. Then I got looking at the pink tube that runs along the frame rail over the air box. It went "under" the frame rail and I was kind of musing, "hmmm.....wonder what that's for ?? Maybe a vent ?? Maybe it's pinched ?? Take another look at the top photo with the V under the carb. See the pink hose right behind the rear corner of the gas tank ?

I pulled it out from under - it Was pinched.......and the bike started right up and ran great. Of all the damned things ! ! ! Must've done that when I was trying to get the air box out to put in the shock and spring.....which I found that I didn't need to do.'s a lesson, eh ?? That's why people call me "Stub-Bourne," a play on my surname.

All done............Lar.

P.S. The bike rides a lot more solidly and feels more....taut...??...precise...??...whatever, I can sure feel the difference.

Glad you found and solved your problem, biglar!

Ordinarily, I'd say only Generation 1 bikes profit from the Tee mod (tee in carb vent line for alternate path, in case one hose is occluded), because--Generation 1 vent tube mouth is only about 10 " above riding surface, subject to stoppage from water crossings, etc.; Generation 2 is at about 30" above ground level, as shown in your images.

BUT . . . if you had the Tee mod on your bike, you'd have had no problem . . . at least, not until the first water crossing over 10" deep!
