Hey;
Right thigh heat problems are really common on v-twin bikes. And no, you'll never get used to it. Kuryakyn makes clear plastic heat shields for Harleys (I've got them on mine and they work great), but I don't know of any for your Yamaha.
Here is a photo of the ones for a HD from Kuryakyn. Maybe you could have someone make you some from lucite or sheet acrylic or modify a HD set. Do you have anyone in your life that's handy?? It could be a cheap effective fix if done properly. You also may want to search the web for "motorcycle saddle heat shields" or "motorcycle heat shields". I've looked but I don't find anything except for HD.
Let me know if I can be of further assistance.
