2019 was the year of the Riva! So many folks in this thread now, so great to see. I've been dailying the 200Z for a few weeks now and it's so much fun and so quick. I try and bait sport bikes/sport cars off the line at lights. Quick update from me regarding the XC180 though -- I've decided to start working on the XC180 again that I originally posted to the thread. I last left off with rebuilding the carb. I finally re-assembled the carb. I was able to replace most everything but the float and pilot jet. Pilot jet head is chipped and I'd have to drill it out. I cleaned it the best I could, confirmed fuel goes through (how much flow, who knows) and will test it before going to plan B (aftermarket carb). I did buy a replacement float bowl gasket (off ebay @FreddyBiz) and put that on when re-assembling. Yesterday, I attempted to put the carb back on the motor and connect all lines while the engine was bolted to the frame. Welp, that's nearly impossible, let me tell you, I truly don't know how I ever got the carb off in the first place. At the same time, I was having extreme difficulty with a few vacuum lines that are so dry rotted that they don't bend at all. They keep falling off the carb, even with clips. One line in particular, goes all the way into the engine block, HAD to be replaced and could not do so without first removing a big rubber cover on one side of the motor WHICH can't remove the cover while engine is in frame! Made the executive decision - got everything disconnected - and dropped the f***er. Going to power wash the whole thing on Wednesday and replace all hoses with fresh ones. I gotta be honest, now the motor is out, the whole bike seems simpler. So much stuff is jammed in between the motor and frame when together. And damn, I don't wanna jynx but this motor appears CLEAN. I'm hopeful that once I can get fuel and electrical sorted that I'm going to have a really healthy scooter. It's made me view the project with increased optimism and enthusiasm. Here's some pics. Also, can anyone pinpoint what the 2 circled connectors go to on the carb?
