I was seriously sucking hind teet on steeps on yesterday's Iron Butt. No mods made to my Fly 150. BTW I also weigh in at 340#. Short of losing 100# or buying up to a bigger scoot, are there any performance mods for Fly 150. Someone suggested playing with the variator weights. I also see that there is a 190cc kit. Will exhaust mod help performance. I am not a grease monkey - so other than basic nut and bolt jobs require professionals.
