Default More Power for my 2001 400ex


im the 2nd owner of a 2001 honda 400ex. a guy bought it brand new for his daughter and she didnt like it cause it has no reverse. so it sat in the garage for years. i bought it and road it for a couple years. it was completely stock. i am in the process of redoing it. ive got my frame,a arms,tie rods,axle,swing arm,steering stem,and handle bars powder coated. also ordered white plastic. performance wise i port and polished head and adjusted valves. also went with a 426 bore kit. and kn air filter and hmf slip on(came with jet kit) my question is, what more can i do for more power/speed????

You can always adjust your gearing if you want some more "get-up-and-go"... Perhaps getting a rear sprocket 2 teeth larger than the current one. Will lose a bit of top speed, but who really runs 60+mph in the woods anyways? (for more than a few seconds)... That being said, you may be a desert rider, and you often run 60+ for extended periods Depends on what you prefer.

You can also get some lighter, sportier tires.. Sounds like you've done just about everything else you can reasonably do, and not be riding around on a ticking time bomb
