My old 440EX custom job, before YFZ/CRF450's existed
I built this along time ago, in about 2001 when 440EX's were running the show as far as 4-stroke performance track/dune quads. I had the IMS hi comp pistons, titanium valve kit, port/polish, etc. was pushing around 50hp at the time. These pics are well over 7 yrs old but thought why not post'em...
