I installed a DG snorkel in my prairie 650 and now she won't fire up right away.Before i put the snorkel in she used to fire up the first time i tried to start her.Now i have to try 3 or 4 times before she starts.I also changed the plugs and properly gapped them.The bike runs great once i get it started.Would the snorkel effect the initial starting being it is getting more air?
