Old School Cool Meets Serious Performance! 🏁🔥

A big thank you to Jimmy Mac for stopping by the other day and showing off his seriously cool ride! We always love seeing what our customers and friends are building—and this 1994 Ultra Classic is one impressive combination of old-school style and custom performance.

Jimmy’s bike started as a 1994 Ultra Classic, gifted to him by a close friend. After needing an engine, he swapped the original Evo for a first-generation Twin Cam, then went to work building a serious combination:

🔧 Wiseco pistons
🔧 SE251 cams
🔧 Decked & hand-blended SE heads
🔧 PAC valve springs
🔧 Cometic gaskets
🔥 High-compression engine build
🔥 Custom headers using a Burns Stainless collector
🔥 Patrick Racing 42mm dual Mikuni carburetors
⚡ Daytona Twin Tec 30081 Complete Twin Cam Ignition

The result is a unique build that combines old-school Harley character with modern performance upgrades—and that custom exhaust setup really brings it all together.

Thanks again, Jimmy, for bringing it by and letting us check it out! We appreciate you showing off the build and representing Daytona Twin Tec. 🤘
