The Watchdog II is designed with the Honda CR125 (RS125) 2-stroke engine in mind and will work on other, similar engines, and is a highly accurate knock sensor device.
It is easy to hook up and use. Just mount with provided fasteners/mounting, route the wires, turn it on, make a run, check the number of detonations, and then push the button to reset the counter. It doesn't get much easier.
Here's what it can do for you:
- Provides detonation counts during a run that can be used to inform the driver if a change to the engine's tune is needed
- Bright LED 4-Digit Counter is visible in daylight
- Light weight
- Small footprint
- No special sparkplug is required (either bolt sensor to chassis boss or directly to cylinder head - photo above shows both methods; all fasteners/adapters included)
- Provides that extra measure of assurance and acts as a "watchdog"
for any errant detonation (just in case you missed the tune, added the
wrong fuel, or a hundred other possibilities that may have occurred)
- Cheaper than "sticking a piston".
INSTALLING THE WATCHDOG II KNOCK METER
Mount the controller/display box so that the driver can see easily, using the provided fasteners.
Mount the knock sensor to the engine, as near the combustion chamber as
possible with the provided fastener or mount directly to the cylinder head by replacing the head acorn nut with the special adapter (included).
Mount the battery pack with four AA batteries (not included) to any clean, flat surface with the high-bond strength foam tape that is affixed to the back of the battery pack. You now have the option to use your own battery source (lead-acid, etc.) or the supplied 4-AA battery holder.
Any detonation will be picked up by the Watchdog II and displayed on the LED event counter.
You may evaluate the tune, based on the number of detonations.
