    Hey guys,
    as title states, just about to get mine up and running, so hoping to find out what others think is the best, will be running a pulley kit (cant remember the size) came off Tom (nikkojoe) and he said was pushing 13psi with a front mount...
    Also, where to find/ part numbers would be very useful.
    Cheers in advance

    I was just running standard bigport sparkplugs with mine.

    NGK BCPR5EY11. Also made 14psi with the front mount (on cold nights). Size of pulley is 178mm (or there abouts).

    BCPR6EP-N-8 is the recommended plug though

    4agze should run 0.8mm gap, so whatever plug you get BCPR etc just make sure it has 8 at the end.
