Posted February 8, 201114 yr Hi guys I have a 2005 dt125x and the other day i changed the chain and sprockets, all went fine until i went to start it up. It would turn over but not fire up. Up until now I have never ever had trouble getting it started. I stripped it down and there is no power getting to the coils. I've got basic knowledge when it comes to mechanics but im terrible with electrics. Has anyone got any suggestions, or had the same problem and fixed it. Cheers Craig
February 8, 201114 yr Moderator I dunno what interlocks the starter may have if any but check the kill switch is off and the neutral light is on and dont take the huff because I asked.
February 8, 201114 yr Author Haha no im not the kind of person to get angry at people trying to help. No the killswitch is off and the neutral lights are working fine and all of my other electrics are working, indicators, pv the lot. i just don't have a spark at all. Cheers Craig
February 8, 201114 yr Author Yeah I've tried a few different spark plugs and I've changed the spark plug cap, no luck
February 8, 201114 yr Moderator Yeah I've tried a few different spark plugs and I've changed the spark plug cap, no luck Are you holding the spark plug metal body to ground on the cyl head when checking?
February 8, 201114 yr Author Are you holding the spark plug metal body to ground on the cyl head when checking? Sorry i dont fully understand that.
February 8, 201114 yr Moderator Sorry i dont fully understand that. you really are terrible with electrics if you are looking for a spark you need to hold the metal body of the plug against the metal of your engine (usually the cylinder head). If you just hold it in thin air it will never spark.
February 8, 201114 yr Just a thot, it all happened after changing sprockets, , does bike have a side stand switch,? you havnt knocked off wires to the switch , ? Welcome craig by the way
February 8, 201114 yr Moderator Just a thot, it all happened after changing sprockets, , does bike have a side stand switch,? you havnt knocked off wires to the switch , ? Welcome craig by the way shouldnt matter with the neutral light on but worth a check..
February 8, 201114 yr Author Ah ok yeah understand that one lol. Yeah I've tried that and there was still no spark. I was wondering if there was anything obvious near the front sprocket that I might have got wet or knocked that could have broken it?
February 8, 201114 yr Author A bit slow with my reply there but no, ive checked those wires and it didn't make a difference.
February 8, 201114 yr Moderator The stand switch is worth further investigation. Check the black/White wire insulation isnt chaffed and shorting to the frame or any metal
February 10, 201114 yr Author I've just been looking through all the wires running down the frame and found one that was broken. Fixed it an it's all working fine. Hopefully I can help someother people now Cheers guys for all the help
