Here are a few simple tips for installing the KOSO Heated Grips[You must be registered and logged in to see this image.]
After removing the stock grips, you will have to shave off the grip ribs from the throttle tube in order to install the KOSO grips. This can be accomplished with a utility knive/file/sandpaper for the most part, but it is painstaking work. If you are careful, a Dremel tool can shorten the amount of time, but you have to take great care to keep from taking unwanted divots out of the tube. After smoothing out the throttle tube, an appropriate length of shrink tube shrunk down over the throttle tube can make for a nicely secure fit. I also found that reshaping the "cone" on the inboard end of the throttle tube with a Dremel cut-off wheel into more of a "wafer" provided a better fit. Take care when routing the grip power supply on the throttle side. You have to allow for a slight "loop" that allows for throttle travel without interfering with any of the existing cabling nor with your grip changes to utilize the brake lever. I found that positioning the power wire slightly ahead of, and below the throttle cables with sufficient slack allows for the best clearance. Allowing for just the right amount of slack in the grip wiring allows the power wires to nestle in amongst the throttle cables at wide open throttle while not interfering with finger motion to the brake lever. Secure the power wire to the throttle side cable bundle with two or three cable ties and route the wire behind the headlight bucket and over to the left side of the frame to enter the left side cowling. Routing the left side power is much simpler, just have it follow the left hand cable bundle and enter the left cowling next to the steering head. As on the throttle side, a length of shrink tube nestled on the bar between the grip and the bar allows for a nice, tight fit. A little bit of persuasion with a rubber mallet is required on both sides.
I found that the best way to provide power is via a switched relay installed in the tail section, accessing switched power from the brake light. Eastern Beaver offers a great option for this in their [You must be registered and logged in to see this link.]
which uses the same brake light connector as the GRiSO. It also allows for adding two additional powered leads that you can use for driving lights or a dash mounted power point.[You must be registered and logged in to see this image.]
The lead for the grips' power control is a bit on the short side, but it is just long enough to route it up to the clutch reservoir to be attached with some stout velcro or double-sided adhesive tape. The provided bar mount is not appropriate for the GRiSO as the bar diameter is too large. Alternatively, you could just secure the power control to the left side grip cabling with a cable tie just inboard of the clutch reservoir.
Just take your time and allot a few hours for the job. Beer helps...
