Hi everybody,

I have a problem with my Roadster 2010, and would like to ask if someone else has experienced something similar.

When I ride the bike, each time I open the throttle or close it, the body of the bike makes a twist. I don't know if it is caused from the engine or from the framework. It is not to much but is a bit unpleasant especially when I open the throttle in turns. When cruising everything is OK till I don't need to open or close the throttle.
When I am not in gear or I'm holding the clutch and rev the engine there is no shake or twist.

When I start the engine and switch to first gear if in neutral the bike sometimes shakes during the switching after that the engine runs smooth but again when I release the clutch to go It starts off with a bit of twist and so on each time I release or apply throttle for shifting.

I would appreciate if someone could share some suggestions.
 
Hope it's not a daft answer---but are you sure it's not just the torque that the engine configuration produces?.
Sozz if I'm ' barking up the wrong tree ':)
 
Hi, thanks for the suggestions!
I just found the problem and it's lost nuts. It seems I was happy for coming back home today in perfect health.
Only one nut left at the bevel box and it was also loose! There was 4-5mm gap.

Wow Dinko ! That is nuts. Er... I mean lack of nuts. Be sure to torque them to the proper spec and pattern. The info is in the service manual.
 
Yikes, Dinko!:eek: The old contra-counter-rotational SNAFU.:evil:

Glad you found that before the gremlins did you the dirty!!!:thumbsup:
