Be careful who you let modify your Harley!

This is the return fuel line on a Procharged Roadglide with a couple hundred miles on it.

The shop that installed routed the fuel line right up the front frame rail and zip tied it in place. This line was melting and soon would have had the customer engolfed in flames.

It's a good thing it wasn't running well or the customer may have never reached out to us.

"the fix" vs stock
Pocket dog slider for late model 6 speeds. Allows for a full engagement of third and fourth gear. Resulting in a much stronger gear engagement.
Accompanies all of our back cut trans stacks.

We use Cycle Rama Camshafts because they simply perform. On the Dyno, on the street and on the track.

Many cam profiles can make a decent Dyno sheet but lack the seat in pants feel in real world conditions. Getting through each gear quickly is always the goal.
