Well like an idiot when i changed the sparkplug on my lt 250R i didn't tighten it down with a socket well out riding in a field today the plug worked its way all the way loose and when it came out it pulled the top off the spark plug wire.. well i tried to pu tit back together it the bike starts seems to idle good but when you try to run it its kinda miss firing could this be cause of the wire or somethign else... what should i check how do i replace the wire

 

You should replace the coil the wire is made into the coil on the lt. If the wire is still long enough you could attach a new end to the wire. And then get some rubber electrical tape not electrical tape rubber electrical tape it cost about 7.00 for a roll but you will need the rubber to protect against the wire arcing else where.
