Q: What about upgrading heads on the Evo’s and TC88s?

With the right combination of parts, you"ll be looking at about 30% more torque and horse power.

Q: What is the cure for a tired 80ci Evo?


The real power is in the heads with the right combination of cam, carb, and exhaust system.  We can bore the cases to make a bigger motor out of it, and we can always stroke them, that’s the easy way to get more power.  We use quality S&S parts and can build any size engine you want.  You can end up with a good dependable 95ci or 98ci motor.  To use new and improved power, you will need a high performance ignition system, balanced to the other performance upgrades.
