The stock main is 118 right? That according to the JETSRUS web page. I was to told to try a 180 main jet when rejetting... does this sound right?

Depending on mods to the bike but a 185 is perfect for a pipe cam and not lid

Ya with the K&N / no lid / Dasa a 185 should about right. Maybe even 1 size higher for the colder winter months.
