| I started having an issue where I'll start my bike up (starts first or second kick from the starter), it idles great. I let it idle for 30-60 seconds, then go ride it. It rides great. When I come to a stop after it's running for several minutes, it idles quite low. I have it set to idle around 1800 normally, and it will idle around 8-900 when at operating temp. I pulled the carbs to clean them, and this helped a little, before it would almost die the idle would go so low, now it does the 8-900. Valve clearances are in normal ranges, this was a sudden issue, one day it was fine, one day it was not. Last year I pulled the carbs to clean and tune, I tuned a little rich, it was getting pops and bangs, but running well. After I got this issue, I turned the screws in half a turn, and it feels overall better when driving than last year, and the pops/bangs are reduced. It also has some hang rev, if I rev it past 3k, it drops and hangs at 3k. Anyone insight is greatly appreciated. |
