I've just received some new grips to install on my 09 Street Bob. For the right hand side the instructions say to refer to the service manual for the removal of the switch housing assembly to access the throttle cables, and for the removal of the throttle cables. I don't have the Dyna service manual yet, but I still have the 08 Sportster manual. Are they close enough to use this manual, or should I wait til I get the right manual in 3 weeks? Or should I just give the dealer £40 to change the grips and be done with it!?
