haunted hill ?

[Storm99]

Im having a strange issue with my 2009 GSA. Theres a humpback bridge in the village I liven in and EVERY time I ride over it the bike coughs and splutters almost cutting out evenm if the fuel tank is totally full ?,

Any thoughts ?

water in the tank?

Traction control kicking in?

Mine also does it on the Uttoxeter to Stone road. The traction works well.

Strangely when I went west to east and could see the road was clear the bike lifted clean off and no funny sounds. Going the other way when can't be sure its clear the ASC kicked in.

Try giving it a handful on a gravel track , you'll wonder what the humback fuss was all about.

Check the connectors on top of the throttle bodies... I had water in one and the bike kept misfiring and running on one when going downhill....

Traction is ok.its definately fuel related I think. She struggles under power at 4.5k revs on the motorway and that culminates into a cough and splutter also.

I have fun jumping a small bridge on my '08 GSA without any dramas so I doubt it's your electronics unless there is a serious difference in your front/rear wheel speeds. Do you roll off or keep it pinned??

 

[Storm99]

Roll on, its right on a junction so I comemoff a flat straight turn left and im immediately on the sharp hill.

If you can ride over it again with the throttle held steady and it runs okay it will prove your traction control is the cause, or you could turn traction control off and ride over it and see what happens.

How badly does the bike vibe when your running flat out?

Do you think when your going over the bridge that you might be pulling a negative G?

+1 on turning the damn traction control off and trying it again.

Is there a mobile-phone mast nearby? We had a Land Rover Td5 that wanked out in the same place with alarming regularity. Never proven but it's what we suspected.
