Hi everyone - my nameīs Robin, and having just sold my BMW K1100RS Iīm on a 96 Aprilia Leonardo 125 - OK, I wouldnīt ride 600 miles on it, but for my commute I think itīs *faster* than the beemer!
Iīd appreciate any comments or observations on the following. My Leonardo was standing for a year before I bought it. When I got it it had 13000K on the clock and was badly in need of a service. Biggest problem for me was the absolutely *painful* pick-up from standstill. From 0-5mph itīs horrible - the revs just refuse to rise and the bike crawls away. But hit about 5mph and all hell lets loose(!) and it pulls cleanly to 65mph! I cannot fault the bikeīs performance in any way, except for this one strange pull-away behaviour, which is frankly scary in city traffic.
I got the bike serviced and itīs better in every way, but the pull-away characteristics are just the same. The mechanic who did the work said ītheyīre all like thatī and waffled something about clutch springs. But I cannot see that heīs right - the throttle response of the bike is fast and clean throughout the rest of the range, but from standstill youīd think it was in 3rd gear on a manual box (if you see what I mean). Hill starts are a joke. And I darenīt even try it with a pillion.
To me it feels like thereīs a fuel supply/carburettor problem of some kind - the revs just refuse to rise, and then suddenly - bam! Itīs away. And even when the engineīs idling as youīre slowing down the pull-away is still good. Itīs just the standstill thing.
Itīs driving me crazy. Any thoughts?
Thanks - Robin
