I test rode a dl1000 today.
Unfortunately I returned the bike to the dealer telling them I couldn't buy a bike that behaved as this one did.
At 40mph, in 3rd I think, it was doing about 4000rpm and whilst holding the throttle as steady as I could it was surging constantly.
About twice a second it was pulsing to such an extent it would do my back in if I had to ride any distance like that. Visibly altering the rev counter by 100 - 200 rpm.
Does any one know why this could be?
I'm disappointed as I really liked this bike and it was the grand touring version with luggage, centre stand and all.
I hope they can sort it.
Didn't have any chatter noises from the clutch which seemed promising after some of the concerns I've read on here.
Any advice much appreciated.
The clutch vibration as you ride problem and fuel issues like this can take some separating out because they happen at about the same engine speeds.
An owner recently made contact to ask about the same constant throttle position surging described here.
Had owned the bike about a month and was also concerned he had the clutch chudder - harsh vibration in all gears from 2,800 rpm to just short of 4,000 rpm while accelerating.
He followed the checks and diagnosed the clutch chudder with the "chudder test" so the basket modification is on his "to do" list and will arrive here soon. http://www.stromtrooper.com/group-bu...tml#post699631
Unlike the clutch issues its much harder to help diagnose fuel/induction issues over email so the bike was returned to the supplying dealer to investigate the steady throttle position surge. They found the previous owner had removed an auto chain oiler and left the inlet manifold vacuum tube open to the air. Perhaps not bothered to lift the tank to close off the tube!! In other words the bike was running ever so slightly weak because a of a small constant air leak into the inlet manifolds. This would be all the more noticeable at the constant speed you describe with the following conditions. Relatively small and constant throttle opening, engine speed constant so the throttle position telling the ECU you did not want to accelerate so the fuel injection volume shut down to a very low level. Add a slight weep of additional air and surging from the weak mixture would begin.(not quite enough fuel injected to fire every stroke - what did not burn on one stroke is left as residue which adds to the next injection so fires better)
Makes me wonder what other invisble but valuable extras a previous owner might remove from bikes just before trading them in? Leaving the new owner to sort out the original problems over again with one or two more added making things even more complicated. Power Commanders, end cans and the rest?
