DirtWerkz Track Test

We performed a track test of the Vertex Crossfire Spark Plug with a 2002 Yamaha YZ250.

Summary: 02’ Yamaha YZ250 MX Track Tested with a used plug, new stock plug and a Vertex Crossfire Plug.

Used Stock Spark Plug
- Bike would start 2nd - 4th kick when cold.
- Bike seemed to run well with no noticeable issues
- Bike would start 1st – 3rd kick when warm
 

New Stock Spark Plug
- Bike would start on 1st – 2nd kick when cold
- Bike seemed to run smoother and crisper than compared to the used spark plug
- Bike would start 1st – 2nd kick when warm
 

New Vertex Crossfire Spark Plug
- Bike would start on 1st kick when cold
- Bike seemed to run great and even smoother, crisper and perkier when compared to the new stock plug. It felt like the bike had more power or in other words that it just appeared to run so much better it felt like it had more power but this is by the seat of pants. The bike just seemed to come alive.
- Bike would start 1st kick when warm

Summary
There were differences between all three plugs. The difference between the used stock plug and new stock plug was better starting and smoother running. When we added the Vertex Crossfire spark plug the bike started right up every time and just seemed to come alive and run very well with a smooth crispy lively feel. The bike felt like it had more power and there was a noticeable difference in how the bike performed and that it was running much better.  We would recommend this spark plug to friends and customers.
