Cough cough and then .. Magic?

[Guest]

I have always worked on my bikes but mostly it was about replacing parts and now that I am old and picked up a bike that didnt cost a fortune I want to learn more about the why and not just the how. So since my carb rebuild I have put about 30 miles on the bike. The previous owner says the bike sat for some 1.5 years. On day one I got around my community and then it would stall when I pulled the clutch. Got home and let it cool down and addressed some areas where air might be leaking in and next day it started right up and I went about 5 miles and then it started to get a bit hiccupy. Next time out I did about 6 miles and then it would hitch at 4000rpm but continue fine past it but then about a mile from home it would stall when I depressed the clutch.

Today I took it out and after about 6 miles it started again except this time I was further from home and didnt relish pushing it a mile or more so I cracked open the choke a bit and hobbled home. Coming down my street it gave a little lurch, a pop and then .. it idled GREAT! I turned the choke off and I took it back out without turning it off and rode it another 8-9 miles without incident and without the flat spot.

When I did the carb cleaning I used the dip for about 4-5 hours per carb and while one of the tutorials on here suggested running a thin wire through the passage ways, clymer said dont so I stuck with clymer and just did the carb dip, spray carb, water and soap and air.

So .. Sticky valve maybe?? or did one of the passages in one of the carbs just break free? Its running great now and I have a new gas cap, and airfilter coming and I bought a gasket so I can do the valve adjustment but like I said .. I want to learn more about why's.
Thank you again everyone

Yes, pushing 450lbs of bike around is no fun.

So you sorta followed the carb tutorials on here (except for wire poking)? Use the o-ring kit from cycleorings.com?
Sounds like your carbs are still dirty, but they might maybe hopefully improve with running since it's sorta running .
the idle circuits in these carbs are easily plugged, so make sure your gastank looks reasonably clean inside.
check (or just replace your petcock) for correct operation.

Yeah carbs that have a bit of dirt can break free. Its a glorious feeling.
