Predator 670 Spark Plug Testing

So we where having issues with the factory Torch plugs fouling out on us due to multiple things like Clogged main jets, Factory fuel pump, Coil failure, pilot air screw adjustment or carburetor bowl float sticking.

So we change out the Factory Torch Plugs with NGK's, E3 & Autolite 3910X Race plugs and show you if there is a difference in how it runs.

The E3 plugs most defiantly ran better over the NGK's, However we still could not get the V Twin to run properly at higher RPM's (3400-4500).

We ended up not running the Autolite Race plugs, we will save this for the Predator 212 build.
