Missfire Sportrak


My Sportrak has a miss fire at low revs, as I increase revs it gets better. It is also very difficult to start in wet but had that before


Usually electrical, so a good service would be the first thing, replace the cap and rotor arm, and the spark plugs, a precaution would be to replace the HT leads.

When there is a problem with misfires at low revs, but itdisappears at higher revs it is usually electrical, usually the HT leads breaking down.


Will try rotor and cap. Had new leads and plugs short while ago
