Thanks Bill, I just did a search again and found a newly listed NOS Suzuki filter, so bent over and grabbed my ankles, and just hope that it will 1. arrive in a timely matter, and 2. actually fit.
The weather was miserable today, but not too bad in the ol' patio workshop, so I spent a few minutes copying the wiring diagram in the online workshop manual, then completely ignored the wiring and removed the right side carb. This carb has been pissing out fuel ever since I installed it, even though I thought I had the float level correct. I reset the level and reinstalled it, turned the fuel on, and it pissed everywhere again. I felt around the join between the carb body and the float bowl, and it was wet with fuel. Hmmnn, I wondered if my home made gasket was somehow to blame? So I swapped in a new gasket, then wondered some more, perhaps the gasket surface on the bowl could be warped?
I grabbed a thick sheet of aluminium and some 240 dry sandpaper, and gave it a rub, and yes, I could see that it was pretty warped. The float bowls on these old Mikunis are a lot bigger than on more modern Mikuni VM series carbs, and so it took a few minutes to sand the thing flat, but I was happy that when I installed the carb for the third time, and connected the fuel line, no leaks. Woohoo! Right then, must be time for a ride around the back yard!
Then I realised that I hadn't yet attached a spring to the centrestand. Hmmnn. I ratted through the goodies that Rich sent me, and found a sidestand with a spring on it, so I "modified" the hook on one end by heating it with my MAP gas torch and turning it 90 degrees. I then spent well over an hour trying to stretch the baastard on.
By now it was dark, and raining quite heavily, so I fired it up again (started first kick, as usual) and rode it out of the patio, up the driveway, thought about going around the block, remembered dropping my Yamaha FJR1200 in the rain on semi-flat bald tyres, decided against it, and rode it back into the patio. Tomorrow I'll take another look at the wiring diagram, after I remove one exhaust pipe, the kick starter pedal, gear shifter pedal, left hand side footpeg, sprocket cover, and then a little cover behind it that screws on under the left hand side of the engine that I think is the source of a leak in the transmission.
I found the same piece in the tub of rotten original engine pieces, and surprisingly it was in better shape than the one that's on the engine, so I'll replace that, and hopefully the gearbox will be as tight as the carbs. More tomorrow.
