    Sorry for the dumbass question - but do bikes in NZ run a catalytic convertor? I have never really thought about it, as I was used to cats having their own little catchment area. Where as the only bikes i have had in the past run either via exbansion chambers or a collectors box/pipe at best.
    Are there suppose to be catalytic converters in the exhaust?

    Most bikes built in the last four years or so (the mid to large capacity four strokes) do have catalytic converters

    newer ones do - just like cars a cat is required everywhere but here, but it's not worth making a special cat-free model for small markets like our own especially when our laws might change (if they haven't already)

    so yes, you can cut out the cat (if there is one, and a lot of them are built into the muffler) and still get your wof, cars included provided there isn't any leakage

    Considering that current 250 4 cyl motors are doing close to these revs, running av-gas in these would be detrimental to performance - even 98 might be too high (ie slow) for them.
    it's not a bad thing till you throw a KLR into the mix.
