My max was right around 80mph +/-.

Your bike can go faster than 62mph. Don't be afraid to work it up a little bit. For a thumper, these bikes are pretty rev-happy.

If you have any questions about the performance mods section, just spit it out. There are some areas where common-knowledge items are left off, but we'd be more than happy to explain those to you. That being said, this bike is only ever going to go so fast. You'll never hit 90 mph on a GZ250. 16T front sprocket, intake and exhaust mods with proper jetting will net you 80mph... same as factory.

If you want to do anything, make sure your tires are aired up, your oil is fresh and filled, your chain is adjusted and, if you really want, raise the needle jet slightly to increase fuel flow in the mid range.
