The neighbors might not appreaciate a dirt bike on the street at early morning hours. I think you'll find the horsepower and top end you've been looking for. If this is the case, then like I said, a good pipe is almost always the answer. I've got a real good expansion chamber on my tadpole trike and it made all the difference in the world. I'm pretty much running a straight pipe on my cruiser (just took out the baffle) and it works alright. It's loud but it runs too good to mess with.
Alright, that's really a relief, I'm definitely game... just please forgive my inexperience.
I did some searching and it sounds like the baffles should just fall right out, but I removed the endcap and they're pretty solid. Reading online about motorcycle mufflers, ehow said to just drill straight up the exhaust port. But my exhaust port/endcap is just a long, hollow tube. There are chambered baffles inside the pipe with round holes for the endcap tube to go through, as well as crescent holes. But I can't get those to come out at all.
So, um... help me please? =) Am I missing something obvious? Should I just drill through the endcap?
