    Hot cam and 12.1 cp piston

    Ive got a 2015 raptor 700 which is booked in for a map in 2 weeks, im looking at installing a 12.1 cp piston but which hot cam would work best?, I live in the uk and i ride mainly on the road with bit of woods and trail riding.
    Current mods:
    Dual barkers
    pcv
    fci
    15 tooth sprocket
    fuel 98-99 octain pump gas
    current bhp 53

    Also would stock valve springs be ok for a stage 2 or 3 hot cam?

    Go with the stage 3, and stock springs will be fine.

    Would I lose any bottom end with the stage 3 cam?

    There's not enough bottom end loss to really notice.

    I'm in the UK and just in the process of fitting my big 3. PC5, dual big guns & k&n filter. Is it best to use the premium unleaded with big 3 or standard unleaded fuel?

    I always use Tesco 99 or shell v power, those are the better fuels to use
