  4. F4i cluster outage, not starting, cutting out

    General Discussion
    Recently while riding my 2003 f4i, the bike would lose rpms rapidly when it hit about 8-9k rpms. The entire cluster went blank on me when I tired to rev through it, like the key was in the off position. When I got the bike home and shut it off it wouldn't start, but the cluster came back on...

  8. F4i tach needle issue in a 93 900RR

    Honda FireBlade
    So a couple days ago i posted a short video in my build thread (it's currently my last post) on how my transplanted F4i gauges show 2 grand as Zero on the tacho. It does the sweep, but stops at 2K thinking it's zero. I haven't got any assistance on that issue, so now I'm starting a thread on...
  9. Should I even bother servicing this '01 F4i which has no proof of maintenance?

    General Discussion
    I plan to purchase a 250-300cc starter bike this autumn. Most likely, after 1-2 years of riding it I'll want to move up to a bigger bike. My older brother's 2001 CBR600F4i has been sitting in the garage for 3 years. It may be the bigger bike I'll want to ride in the future. How much money should...
  10. 06 CBR F4i

    Just lowered my F4i with the adjustable Soupy's Performance kit. I feel a lot more comfortable now, being able to touch with both feet. I had also shaved the seat, removed the foam and installed 1 inch foam. I have not noticed a difference with the way the bike handles, but then again I'm a new...

    I took the fuel pump out while putting a new therm gasket in and when I put it back on it dripped quite a bit. When I took it off it had the regular gasket and then another one cut to sit on on top of that gasket. So I bought a new one and when I put that it and tightened it down it pissed fuel...

  19. Power Commander 3

    Aftermarket Perfomance Parts Reviews
    Are there noticeable improvements with a power commander? I recently unhooked mine from my 06 F4i when I changed the battery and the bike seems to run smoother. Probably did not have it tuned correctly. I bought it used and it didn't come with the seperate power cable to allow me to power the...
