Bought an 05 K5 DL 650. The thing wouldn't idle. 800 to 2K rpm with 1 cylinder intermittent. I took the bike back to the dealer at 3 miles (their set-up miles), I never rode it. The dealer changed a spark plug, that's all they said. Idle seemed better. Sunday, first ride. 42 miles. Idle good, after I bumped it up from 1100 to 1300rpm. To start off you need to rev to ~2500 for a smooth take off. anything less, it bucks and coughs. Symptom 2: when rolling on the throttle is anygear from 2000 rpm, she coughs until above 3.5K or so. 1/8 to 11/4 throttle positions seem to cause the coughing. I've had at least 75 different bikes from 1950 to present. all but 1 carb'ed. My 92 Ducati 907 (injected) was smooth....never a hitch. I had a first year SV650S that I bought in Canada (carbs), smooth as silk, no issues. I do know what I'm experiencing here.....and I do know that I have a 650, not a 1000 :wink:
Peace through ignorance!
