    Have tried the 43.5 FCR and the 43 on methanol, the riders all liked the 43 on Q16 VP with the nitrous better.KP

    Well I'm trying a 50lectron. 662cc is alot of cylinder for a small carb to feed.

    The 50 would provide more top end but we have plenty with the nitrous oxide!

    Slightly different applications. I'd venture to say the Team Peterson bikes need a lot more throttle response.

    I am having a head done up and once I get it ported I'll donate (temporarily) it to anyone that is getting ready to dyno as long as they are willing to swap out the head and retest. Preferably someone with 570+ cc motor. I'll provide all gaskets. I would do it myself but I done have the time.

    KERRY P would you be interested in testing one on one of your H/C bikes?
