I have a 02 drz400. I have not even rode it yet. I cut the exhaust tip to 1 3/8in. Now I was wondering about jetting changes. Or other low cost performance mods. The bike is just off the showroom floor so it is all stock. Any advice would be a great help. I heard to put a 165 main jet that seems to be a bit much when I removed the stock jet it is only a 142.
