Hi, my 600 is not running well it back fires, does not start good. I think  the problem is in the carb. on the belt side. Took carbs off and cleaned. are there fuel filters that i should change, any ideas would be great.    THANKS  PUFF

not sure about the 2000 but I had to install a filter on my 66 MX6.  A cheap investment for peace of mind.  Installed a fuel-shut-off valve at teh same time.
