Jet Question With My New Exhaust

[Popeye]

I just bought this exhaust: https://www.denniskirk.com/dg/rcm-steel-complete-exhaust-system.p44538.prd/44540.sku for my 81 Honda 200 atc and I figure I can go up a jet size or so. If so, what size should I upgrade to?

Thanks for any help!

You may want to post what jets you have in there now in order to get an answer. Also if you currently have any other mods, or if is all stock.

I bought the same exhaust for my Yamaha DRN 225. I called DG for jetting tips, they said "start with going up 2 jet sizes on the main jet, and move the needle clip down 1" (make it richer). My DRN runs great with this exhaust, pulls strong thru all the gears, a little loud, 92db on my meter. I haven't had the chance to put the G.P.S. on it and see if I got more top end.
