You've already got the Yammy topbox judging from your avatar pic. If you want to actually carry stuff as you travel, consider saving up for a Givi, as well as the seat you want to buy. Givi's rack/handrail is steel tubing, replacing the stock plastic rack/handrail assembly. There is no one reporting a subframe crack failure who uses the Givi rack. The Givi boxes are much more useful in shape and volume, as well.
If you need to delve into the bike further than just lifting the tank, I humbly refer you to my
fairing and cowl removal thread for Gen-I FJRs. It's not in the FAQs like Kaitsdad's Gen-II thread, which I find to be an egregious oversight and an affront to my status here by the powers that be
, and even I have to Google it to find it when I want it.
A big +100000 on the Master Yoda riding position. Put no weight on your hands. Any forward lean should be at the hip joints, not in the spine. Back straight, then. Legs and back hold up your upper body, your arms and hands do not. To check your position, let go of the bars while riding. If you have to shift your weight, then your position was incorrect.
I've been babysitting my brother's VTR for a couple of years. He abandoned it here when he moved to CA, apparently unwilling to ride it that far. (Gee, wonder why. How many gas stops would it take to get a 100-mile-range bike from here to there!!!!!????!) So changing your posture will be a BIG step from that bike to this. The VTR is a hoot for a half hour or so, but then I'm ready to park it and do something else. But it surprises me to hear you say one of the reasons you went to the FJR from that was lean angle. Was your VTR lowered or something? I seriously doubt the FJR has a lean angle advantage over that.
