full tilt viper
New member
Just pulled the plugs on my piped viper. On the mag side plug the 90 bend was broken clean off at the start of the bend . I was still running but it did'nt sound right, that's what led me to check it. I took my flex light looked into the cylinder . It did quite a bit of dammage top of piston , front side etc. Did a compression check 105-107 , 120 in other jugs. Can i run it at that compression? At this point in the season in don't want to tear it down.Do you think i can make a case with NGK ? It was obviously a manufacturer defect.
