Recommend starting point for jetting with current mods

[noid]

The gf's blaster is stock except for a K&N filter with lid still on and no intention to take off, boyesen reeds, and fmf silencer (stock pipe).

The stock carb is currently running a 237 main (never knew they incremented like that). Should I go up? The season riding temperature will be 15-28c at an elevation of 600-700ft.

On hand I currently have a 240, 250, and a 270.

Just fixed an air leak, and have yet to take it out for a nice lengthy ride to then do a plug chop. So it would be nice to make an educated guess on a main size before said trip.

Suggestions?

Most fmf guys are running 270's.

With just a silencer but stock pipe?

I'm sorry my old ass didn't read correctly, I'd bump it up to 240-250

Pretty sure that has to be an aftermarket jet. never heard of a 237.

This is on sudco site- no listing for a 237.-
