Somebody Help!!!! NC23 probs

[mattiec321]

Ok chaps, having swapped my loom over and now have a good spark on all 4 all I'm getting is backfiring as if it's firing in the wrong order. All HT leads are in the right order and are within spec as are the pulse coils.

Has anybody suffered any issues with the ignitech box such as this? If I was to plug it into the computer would I be able to see what the problem is?

The box was the last thing I moved before the bike went bent and refused to start. I've checked all wires for continuity on the CDI and also the Reg Rec... all are giving good readings, Two things left are to change the plugs and remove the carbs to see if is something silly like a stuck needle valve flooding the thing. but as the problem initially manifested as a non firing 1&4 I'm skeptical about that. If its not that then i'm stumped.

Would there be anybody in the Kent / Medway area that would be willing to a lend of their Cdi to try to eliminate the possibility of a blown CDI ?

This is my track bike and the season is getting well underway and I'm left on the sidelines .

Please Help

Right after trying a myriad of things it turned out to be dead plugs on 1&4
