Hiya guyz, Been offline for a while was tied down with work...so hope all the guyz doing well.. Would you guys tell me how would you identify faulty plug caps with a multimeter or any other means? My engine's got a lazy start, a heavy misfiring going on in front cylinder..like it fut futs doing well at lower gears. However you can still ride, the issue starts to appear right after you slower the bike in order to turn or at a zebra crossing. I have to accelerate greater than usual in order to make her move right after some stop. I checked spark plugs and the front cylinder had sooty black carbon build-up but the sparking points were clean at the gap, carbon build-up was around 20% which I think is normal? The rear cylinder had no carbon at all and the combustion seems to be good. Both spark plugs are new and genuine NGK made for Yamaha. I saw on the net there is a resistor in plug caps, may be its damaged, I tried to check continuity in caps but no reading came out in multimeter. Is it possible misfiring to come with bad plug caps? The misfiring comes all the time right after washing the bike or riding in the rain. In that case also engine starts to fut fut at low gears but sometimes at the 1st when I accelerate more the bike moves speedily. May be faulty ignition coils? How can I check them with multimeter? There is a sudden brightness increase in the headlight also, it comes on and off, sometimes the brightness remains for several minutes and reduces... Does my bike having a serious issue, have you guys come across the same? can oxide buildup in plug caps or something cause this? Faulty rectifier? or battery? Please help me..thanks guyz!
