    Need some CRF100 help, back fires and tires.

    Kinda rhymes huh?

    Any way, my wifes 100 was back firing a lot yesterday, generally after cresting a hill and starting back down. Not really sure as I wasn't riding it.

    Totally stock carb and engine.

    Also, any idea on tires and pressures? The stock Maxxis hard terrains aren't the best. She had a hard time in the rocks and such, lowered the pressure and it was better but I think the tires are lousy.

    Should I go with the same as what I'd put on my 250x? Dunlop 756/952 with heavy tubes?
    Do not send me to a heaven where there are no dogs.

    165 main, 42 pilot, JD Red needle 4th clip, R&D Flex fuel screw 2 turns out, open air box, FMF Q4. 4-9000ft, 50-100*

    1] The popping is probably due to jetting, although there could be other minor things.2]I usually run 14 in the front and 16 in the back for harescrambles, but less should be used for tracks.
