EVO Street Fighter Kit
This is a great way to enhance your 80” EVO motor. We install an oversized intake and exhaust valve, open the ID of both ports to increase the flow, then hand blend our multi angle valve job to the seat bowls. We surface the head gasket area to increase the compression for our supplied piston. Add a T-Man cam to this package, and you have put new life into your older bike.
Click the Kit Details tab for a complete description of parts and labor. For more details on the best fit for your riding style- call T-Man Performance.
Kit packages require your cylinders and heads be sent to T-Man Performance for work to be completed.
* When not using T-Man Performance pistons the builder is responsible for checking all valve to piston clearances.
