Hi all, been away a while, trying to get back into it. My bike sat for a long while with multiple problems. I finally got to working on it and rebuilt the carburetors with the kit from Randakk's, replaced all the coolant hoses (despite the OEM Honda lower radiator hose not fitting properly), replaced all the vacuum hoses under the rubber mat, intake gaskets, etc. Got it together, tuned and synced the carbs, and she ran like a bat outta hell, smoked the back tire and left a black streak 30 feet long. Rode about 20-30 miles, then had to leave her sitting for another week or so. Got on for a short ride, and she ran like crap.
Finally got to her again, seemed like she was lean on the left bank. A little propane near the intake smoothed her right out. At first I thought I had somehow gotten a piece of trash in the bowl, despite new Honda filter and fuel pump, so I tore into it and found... NOTHING. Spotless as I'd left her. Blew through the passages with compressed air just to make sure, back together we went, and ran great... for about 60 seconds. Didn't have the air box fully sealed so I was able to confirm that propane in the right throat bogs it down, propane in the left throat smooths her out. Ran the hose from the propane around the intake gaskets, up under the mat, and all around, only makes a difference at the opening to the carb. The thing is, it comes and goes. Is that typical of a small tear in the diaphragm on the CV slide? That is the one part I didn't have to replace so at $100 a pop, I didn't. The slides seem to move in relative unison, though without the air box fully installed, it doesn't rev much very well anyway. I also checked the fuel petcock with the propane, nothing there (as I recall from when it failed many years ago, it caused a lean miss on just one cylinder, rather than the whole bank). Just wanting to make sure I'm thinking right before tearing the carbs back out, AGAIN.
Thanks in advance.
