Re: Carb. Vent Tube
I mounted mine backwards, and only had one near stall at Barnwell. A quick tap of the clutch remedied that. you can also fill in the opening and drill a new breather to prevent spillage, although I always seem to find something else to do to my Zuki everytime I get around to doing that.
Once you get the jets and the floater level set properly, all you really need to do is re-adjust your mixture every so often. I always adjust mine before and after a long day of trailing.
There is a hesitation I have never been able to get rid of, but it is something you have to live with as a Weber owner. You can move the hesitation u pand down the rpm range, but never get rid of it. Mine is in 1st gear about 700 rpms. I give it gas and it hesitates a second and lurches slightly. never seen a Weber that doesn't do this.
Never used or seen a pony in action myself, heard nothing but good things about them though. I'll sell you mine when I get to Fla for $225 with the modified manifold, K&N filter, and adaptor kit
