Heateg Grips too long!

[Bizbauer]

Hi all,

Currently fitting some R&G Heated grips to my '02 foxeye to get me through the winter up here...

While checking all the bits for fit and size noticed the R&G grips are a full 10mm longer than the existing grips (125mm vs 115mm as standard).  I'm kinda nervous about chopping this amount off the grip for fear of cutting through the heating element; and the controls won't go inboard due to the notches on the bars so has anyone got any advice so get by this issue? 

Has anyone come across this before?

Have the standard bars fitted which I like so wasn't wanting to have to get Renthals or similar just to get warm hands.

Cheers
