yup, got full monty and ignition advancer and thrown on a 2 teeth larger rear sprox. dont seem to have any problems.
i found it a little more viby with the rear sprox change , as you would expect, it revs higher for the speed your at, but noticed little change with the advancer. seemed to clean the pick up 2-4k rpm but didnt notice more vibes or any good/bad effects above that.
i allways say the true test to any mod is if your bike was replaced with a std one would you do the same mod.
HUGE yes to full monty ivans
Yes to the 2 teeth on the rear
prob not on the advancer, i found no down side but the upside was limited
