Green goblin ( Another build)

Here’s the starting point just got it for 5 dollars.

My bike really likes this set up, it pulls great all through Out the rpm range. Mine is just a fatty belly pipe from Amazon.

Mine just shot up too about mid-December. I got a pipe from amazon too. I got it to go 30mph. I'm scare to mess with anymore. I do like them louder. I believe loudness saves lives because if cars don't see you, they can hear you. I'm going to be nice and quiet them down.

I was not after power at high rpm, what I did lowered the resonance range to a lower rpm so it is usable for normal riding. Cannonball3 did the same on a pipe on a YD100 and got good results for his too. I'm building a 49mm engine and may try this set up on it. I like the sound of it, mine sounds like a YZ 125.
