gday, my xJ900 is misfiring when warm at around 4000rpm, coils have been changed and carbys have been cleaned out, all spark plugs seem to be good in all cylinders, can any one help im at a loose end:(

Pick ups?
on my gix 11, it would misfire every now and then when warm. The pick ups would over heat, replaced those and all good.

cool thanks for that, its strange tho cause after it has backfired and farted a bit it comes good for a few seconds then turns too shit again. Time to get the manual out and see what pickups are thanks again hooligan

Control box on betty did itself in on my way to AFR10 would run fine till 6000rpm then the as the timing circuit kicked in it ran like shit backfired and was a general pig , below 6000 was fine. Was a dry solder joint in the box (potted and a shit to fix)

excellent thanks, i think i will try control box first, dosnt look as technical as the pickups

I found my issue by just swapping out the box with a know good one, then stripped the dead one and fixed it. Tricky and Looking back i'd not bother to fix another but just make another from a kit or buy from the net.
