    Best mods for RVF 400s

    right after seeing my rvf turn a muddy tractor over the last couple of weeks ive decided to get it back looking mint with some serious power mods and never to use it again in winter!!!
    Im just wondering apart from the sweet exhaust system that tyga are making for the rvf what other mods are really good for power. My RS250 is about maxed out powerwise with varios kit parts so i can now spend some dollar on the h**da. any help from dave or craig would be much appreciated.

    Heres what im doing to mine:

    - Moriwaki Twin Stack Exhaust
    - HRC Jet Kit
    - HRC CDI
    - HRC Air Tray
    - HRC Airbox (although i dont think im fitting it)
    - HRC Brake Reservoir Cover
    - HRC Rear Brake Reservoir
    - TSR Jack Up Kit
    - Alloy Can Hanger
    - Earthing Mod w/ Gold Connectors
    - Double Bubble Screen
    - Black Screen Bolt Kit
    - PiperX Filter Mod
    - Solo Seat Cowl
    - Denso Y31FER-C's
    - Uprated Rectifyer
    - IRIS X-Ring Chain
    - Renthal Hard Anodised Sprockets

    Most of the above i can source, including most of the HRC stuff although the 3 CDI's and 3 Jet Kits i have arriving will most likely be the last i get due to them being the last ones available from HRC. If you want Tyga stuff let me know as i often have orders with Tyga.

    ok guys many thanks. just out of interest how much is the HRC ecu and does it only work with other mods like the kit ignition on the rs250? How did you get on fitting the jet kit craig? the carbs are a nightmare arent they, there all vacuum operated and stuff and the float chambers look almost inaccesable!!
