    cheapest way would be 3 blade 15/19 impeller, rotax racing supercharger impeller, xspower intercooler, 4" rear intake, 42 lb. injectors.

    best way would be riva stage 2 minus the riva s/c impeller and get a rude charger with 50lb. injectors and rr ecu, lightened valve train etc..

    There is a huge difference between high 70's and low 80's. Figure $5000+ on mods.

    For handlebars you can go with a UMI steering system, or simply install the Riva handlebar extensions and finger throttle kit for less than $200

    Rotax Racing oil pressure jet $42

    4-Tecperformance water strainer kit $42
    Riva valve train upgrade $599
    Riva grate $120
    Riva Finger Throttle Conversion $199
    Race Engineering Block Off's $309
    Les Cooke B kit $1900
    Ceramic Supercharger Bearings $135
    Fuel controller with 50# injectors $850
    Skat Trak modded Tripple Bearing Pump $350

    Umi makes a whole set up which costs some bills but looks and people have said is well worth it. Someone on the forum sell the kits on the forum i forgot his name though someone will chime in. He can get you everything you need to make it work. Ill be getting the set up come spring. You can also get riva finger throttle and extensions kit if you want a stock look and also costs less.
