bansheelapointe Posted July 10, 2015 Author Report Share Posted July 10, 2015 well i checked the coil ground and checked for spark and it was really really hard to see if there was any spark used a new plug and checked both and almost could see spark with one but not the other is this a bad coil or cdi or what Quote Link to comment Share on other sites More sharing options...
bansheelapointe Posted July 11, 2015 Author Report Share Posted July 11, 2015 so you can see the spark pretty easy when its working right, i know in my srv snowmobile when i check spark this way there is no question if there is spark or not it a freakin huge spark?

bansheelapointe Posted July 11, 2015 Author Report Share Posted July 11, 2015 well i have the head off now cuase i sent the domes to noss machine so they can make me some custom ones i had the dreaded trinity domes, so when i get the new ones i will put all new o ring on the top, as far as the coil it did run and start still before i had it apart but every now and then i would get what sounded like a rich issue and it would come and go and i knowmy jetting is on so yeah Quote Link to comment Share on other sites More sharing options...
