Jetting question

[charbison]

I just got a 01 Warrior. It had an aftermarket exhaust and the previous owner said it needed a new jet for the exhaust as it sometimes cuts out and backfires. After some reading I think I’d need a smaller jet. I also read that increasing intake flow with aftermarket filter or cutting air box lid, would require a bigger jet. Might be a stupid question but if I did the air filter and air box mod would they cancel out or will I still need to re jet? Thank you

You probably need to go bigger on main and pilot.

Nice warrior, welcome! Any updates?
