How does the bike operate when you ride it normally: with rpm at 3k or above? Maybe you should just stop lugging it. It wasn't designed to run at such a low rpm.
Come on, Fred, if it runs differently when wet than when dry, then there is something wrong.
I totally disagree that "It wasn't designed to run at such a low rpm". The FJR will pull smoothly and without distress from tick-over if you want it to. Wet or dry. As I've stated more than once, running under 3000 rpm is not necessarily "lugging".
All three I've had would run very happily below 3000, in fact about town that is certainly their "normal" running, and none were any different in the wet. Also, all have survived proper Scottish all-day downpours with no difference in performance. Me, yes (picture a drowned rat), but not the FJR. Very often on my Gen 2 bikes I would deliberately use low rpm because of the lack of traction control under wet slippery conditions, that is still my habit with my Gen 3.
Now, my pre-FJR Trophy
really didn't like the rain, until all the plug leads were replaced. I think it was made with left-over Lucas leads.
