Overflow

[schedMas]

I just got my CB1 last week, after several days of daily commute to work, one of my carbs overflowed.  I thought it was just a loose clamp or cracked hose, I remove the tank and checked, it was definitely an overflow.  What i did was i drained the overflowing carb then restarted the engine, the leak was fixed. . . hopefully.  But then I observed the exhaust pipe of the carb that overflowed is not heating up thoroughly compared to the other three pipes.  Is it that the spark plug is no longer burning properly due to the overflow? or the carb itself?  hope its not that much of a problem, thanks for any advise.

i would suggest that you first replace the spark plugs if you have not replaced them since owning the bike. the original plug for the -1 is CR8EH-9 NGK or U24FER9 nippon denso. i personally prefer the ngk CR8EH-9. replace the plugs and go from there. could also be dirty or clogged jets. it would also be a good idea to replace the fuel filter and air filter if you have not replaced them yet
