Suzuki DR 650

I made an account just so I can say THANK YOU for sharing your DR build, you don't know how helpful and integral it will for me. ??✊?

Hey John, I have a DRZ650 and have been thinking about doing the same thing you did with your bike: the CRF 250 twin-pipe idea. I was a little skeptical about the bike's back pressure on the header pipe due to the pressure difference when swapping pipes. Could you give me any information on that?
