 UPDATED Heated Grips
Eventually I bought Daytona heated grips, £45, I managed to remove the OE grips without damaging them. I have not glued the Daytonas on as they are so tight and I cant see them moving. The throttle grip needed fettling with the B & Q dremmel, both are fixed on using the OE bar ends. I soldered the live wire to the aux. outlet socket wiring on the underside of the fuse box and the negative to the headlight/chassis. I made a simple angle bracket from stainless which is bolted to the tapped hole in the centre of the handlebars and the control switch is glued to it.
Havent actually ridden the bike yet but in the garage they worked a treat.
Thanks to everyone for their tips and information and James who assisted throughout the head scratching stages and tidied up the bracket. |
