So ever since I picked up my 450r a little over a year ago I've been wanting an exhaust. I'm just not satisfied with the sound coming from such a aggressive bike. I've been eyeing a full dasa system for a bit now but I wonder, if I jet the bike to match the exhaust what will happen if I put the spark arrestor back on for certain ohv parks? Will I have to rejet the bike or will I have to go somewhere in-between? Sorry if this is a dumb question i don't know much about carburetors other than how they work and taking them apart.
