How To Perform A Leak Down Test On Your 1997 – 2001 Honda CR250.
Click Here For The Full Ste-By-Step Guide!
The Parts You Will Need Are:
- Tool & Parts
- Oil
- Coolant
- Fresh Spark Plug
- Clean Filter
- Fresh Gas
You should take at least an hour to break in your engine. This might seem like overkill but I would rather lock up at five mph in my driveway than 30 mph 5 miles from my truck.
Before you do anything, refill your oil and coolant.
Make sure to use a clean filter, spark plug, and freshly mixed gas.
