Im thinking about trading my 1980 trailcat 4000 for a non running el tigre 6000it worth it?, is this a good sled? the guy says its not getting spark i havnt seen it yet but hopefully early this week i will. no sparks usually caused by bad cdi or coil right? is ther a way to check if both cdi & coil are working to find which is the problem if this is causing it. my other question is he says its a 6000 and arctic cats website says the 6000 for this year has a 650cc l/c but ive also heard 530 l/c, he on the other hand says its a 500cc l/c but he told me thats the original?! sorry if im not doing this post right, this is like my 2nd one..
