Love the discussion people. I have gone the two-brother route, (primarily to reduce weight), air box mod with K&N filter, but nothing more. When is more power too much power for an FJR? At 60 years old, I think I have enough… but then I find myself on a two-week 5000 mile adventure and a go-fast Harley wants to check out a FJR… and for a moment it is 40 years ago and I am saddled up on a highly modified R-5. Only speed problems encountered is a very high-speed light front end wobble with a trunk loaded to the max. Life is always good on a FJR, but most important to arrive in one piece after a long day on the road!
