Shark Stalling issue

[sshevie]

Heya all Ive had a issue crop up with my shark. It will run fine all day at 45 and below. however if i have a 20 minuet ride at 55-60 it is stalling out when decelerating. even just allowing it to compression brake down from 55ish you can feel it bump starting itself. It restarts immediately after stalling out.
I am guessing its a carb issue if so what replacement carb pod filter and air intake do you recommend? I remember someone building out a TT250 witch has the same motor but for the life of me I can not remember who.
Thank you for any ideas and suggestions in advance.
