Recommended Posts

Hi i Just bought an fmf jet kit for my 08 650l and i already have done daves mods and drilled the holes out to 5/32, Can i still install the fmf spring without problems.

i had done both on my L with no issues before installing an R carb...👍

some have said there is potential of some flutter of the slide associated with changes in pressure caused by a big single piston on a thumper BUT i have never read where anyone claimed to have this issue...

also i read where one person had an aftermarket slide spring become unseated do to a different design from the stocker BUT i don't remember it looking any different :worthy:

:busted:
