Try jetting down a size or two. I think F-5 Snopro's 53/51 helix is giving him a great advantage on the bottom end. Also, If you're using a ton of oil, make sure your settings are correct. If you're running a std track...I'd invest in studding. The F5 is only going to perform in the short shots with the F7...your hook-up and suspension will go a LONG way.
