Well, my bike ran in short bursts and the died. Today I pulled the carbs and gave them a check. Both floats were leaking so I soldered, tested them in water and then tomorrow I´ll put them back on the bike again. I also discovered that I had connected a vent hose wrong. Hopefully I´ll start the bike tomorrow.
I followed my own advice and checked the links from JOINTS. Check out Motoshop Tonouchi. These bikes are theirs:
Fingers crossed for tomorrow. I´d be VERY happy if the bike started with no problems. Then I could refocus on painting the tank again, fabricating the bracket that would raise the rear end of the tank about 3 cm to get it level with the frame, mount some loose end and do the virgin run.
