Hello! So I have a pretty big problem here, and I'm at a loss... when I bought my Honda CB125s (1974) it ran great - revved fine, could hit 65ish (pretty good for a almost 45 year old bike). Then it sat for about four months while I turned it into a cafe racer. I took it all apart and cleaned or changed everything except for the carb/engine because it was so good. I recently finished it and about a week ago I tried to take it for a ride. It idled fine, but when you got going it wouldn't rev past 6K in first gear. It got better as I got up the gears, hitting 8 1/2 grand but not perfect. Then when I was going about 50ish it bogged down. Had to push it home. First thought was instantly the carb, and fuel delivery. I put a new petcock on the tank, and fully cleaned the carbs... twice. Lo and behold... it still wont run smooth. Then I tried to see if it was not getting enough air so I took the air-box off and tested - did not fix it. I am going to see if the timing is off but it was recently done, and the fact it simply just stopped working makes me figure it's not that. BTW, I screwed around with the carb - moving the float does not fix it. Maybe I am missing something obvious but I am at a loss. I would like to bring it to a mechanic but I am 17 and cannot afford it. Please let me know if anyone has had similar problems, or any possible solutions! Thanks!
