Something has taken a giant shit and it sounds expensive

My worker had a bandit 250 with a similar sounding problem, missing and no balls in the mid rev range 8000 to 12000, was a 93 with original ht leads and probably the spark plugs too, replaced them and it made a huge difference. Something to do with current being too much for the old worn out leads was only running on three cylinders half the time until we put the new cables in.

Should update this. Bike is going, have been riding to work for the last 5 or so weeks. Its not too bad over all. Has developed an exhaust leak (partly why it was running like crap maybe?) Anyway that's the reason it backfires. Also noticed the clutch slipping if/when I change at higher 15-16 RPM, usually in first and second. Saving up to get them fixed, going to get carbs balanced as well might as well have it running mint while I ride it for the next few years.

Had more than its fair share of teething problems but I quite like it now despite all the headaches.
