Next, would you provide a link to those grips? I looked on Amazon and didn't see any that looked like yours. Thanks!
If you're outside of the USA and the Amazon seller won't ship, this ebay seller has the same item for about the same price.

(I know ebay links don't last forever so the seller is "thejumbodepot" and the item description "Brand New 7/8" 22mm Electric Plastic heated handle bar grips for Honda Kawasaki")
That has a compatibility chart which doesn't include the TR650 but they are a perfect fit and it's only a 5 minute job to fit them (not including the wiring).
The wiring supplied is exactly just long enough to let you hide everything in behind the headlight shroud. I wired mine up with a relay that is active when the headlight is on.
