07 R6 idle and cold start problem
My 07 R6 have some problem.
1). Cold start problem: When engine is completely cold, it will start with no problem at first, but when I try to warm up the engine and just let it idle without any throttle control, it will idle and die within 30 to 60s (RPM around 1300 to 1500 then gradually decrease and you can hear the engine start to die. Especially in cold weather). Once it die, it will hard to make it start again unless turn off the key, wait for 10 to 20s, then it will start again (the temperature is still low, and I think I have wait for 10 to 20s because of the auto-choke, plz correct me if I am wrong). Once the temperature reach 130 F then the engine will restart easily.
2). Idle problem: When the engine is in working temperature, idle in stop sign or holding the clutch to the bottom in low speed, the engine tend to die easily if release the throttle suddenly. So I tend to avoid sudden release on throttle in stop sign.
3). I just change the spark plugs, all four old spark plugs seems burn fine and evenly. The bike have 40K miles, and I learn and do the regular maintenance and oil change by myself.
4.) Do I need do a valve measurement? Will it fix the problem? The menu said do valve adjustment every 26K. Do anyone have a more detail step or video how to perform a valve measurement or adjustment?
