Carefull on the plug

A hotter plug is not a performance enhancer.

The heat range of the plug is based on how the engine is tuned... and it is very unlikely that you need a hotter plug once you start to modify a motor.

Modified motors usually need COOLER plugs... because the increased performance makes them run hotter... add a hot plug to that and you will have a hole in the top of your piston... (maybe).

Base the plug heat range strictly on what color your plug is while running wide open.

In other words... finish your break in... settle on your oil mix... run it good and hard for a half mile... stop on the spot.... and pull the spark plug... If it is a light brown (tan).... leave that plug in.

I would recommend leaving the stock plug heat range in and altering the main jet to suit... not the other way around.
