Yamaha YFZ450 Dyna Ignition Box
Part: DFS7-12P

The Dyna FS is a direct plug in replacement of the stock ignition that pugs into the stock harness. This Dyna box produces a longer and more intense spark than the stock ignition. This feature alone adds enough power and torque to warrant the price tag, but that's only the beginning. The Dyna lets you change the Timing Advance Curve! The Dyna FS ignition reprograms your YFZ450 to release that power with 4 ignition advance curves - 3 high performance and 1 stock curve- which you can easily choose from as you ride. You can also change on the fly by flicking a switch.

$349.99
Non-programmable models are also available. Please call 1.877.FASTOYS for more info.

Yamaha YFZ450 Pro-Port Porting

Porting is a highly technical and intricate part of any performance engine package and has been one of our specialties for over 30 years.  We invest countless hours yearly in R&D allowing us to offer our customers the highest quality and performance possible. This investment keeps us one of the Industry leader’s in High-Performance Porting. We have the expertise and the equipment to maximize peak performance throughout the full power band, giving you optimal performance without compromising reliability and engine life.

With the use of our Superflow flow bench with port flow analyzing computer software we can map out specific areas within the ports using pitot tubes of different shapes. These tools allow us to see air speeds through out the port enabling us to achieve maximum port efficiency.

Testing port velocity and port stability is the only way to insure getting the most usable CFM (cubic feet per minute) from every lift point. The use of computer monitored flow benches are an excellent way to measure and diagnose port designs, ensuring maximum performance. The use of this equipment also helps determine cam design and valve size for specific riding requirements.

Trinity Racing uses state of the art technology and techniques to create the perfect port job according to your unique specifications.

We have available Pro MX, Pro TT, Stage I,  Stage II,  Stage III and Stage IV
