Question Common upgrades/modifications

Good Afternoon all you wonderful people,

What are the most common mods done to an older stock Harley? Easiest mods? Cheapest mods?

These can be engine mods for power or aesthetic mods for looks. Appreciate the input

You need to determine your goals for that bike? What bike are you talking about? Do you want a drag bike? A sleeper canyon carver? A touring torque monster?

It's been recommended by many to learn on a sporty. Once I've gotten the hang of things, I like the 90's soft tails. Im looking to have a a nice looking/sounding harley for casual rides/cruises. That may change once I'm officially on a bike but for now not looking for any sort of drag/racing bike .

Basic modifications for performance to a stock Evo or Twin Cam motor are incremental. The first step is replacing the OEM intake and exhaust with free flowing replacements of which there are many. The next step could be a BB kit or adding cams to the first step, or both. Of course, if carbureted, tuning the carb and a programmble ignition should be part of the either upgrade. If a later model with EFI, a dyno tune should be part of the upgrade. Next step beyond that would be porting the heads.

Upgrading performance in steps is expensive and often results in two steps up and one back. The best approach to performance upgrades is to establish a budget, price out the desired upgrades which many times will exceed the budget. This is where most mistakes are made. The owner wants to upgrade, can't afford the complete upgrade plan but has to "do something", does what he/she can within the budget, finishes the upgrade and gets smoked by his buddy that saved and waited for funds to be available for the complet upgrade.

Anything other than stage one you should consider cams, heads, bore, to save on labor. With fuel injection it's an investment to tune too

For me seat is pretty high on list. First purchase is factory manual.

I like jacking up head lights with halogen, and LED options too. Need to figure what previous owner did first


Ride it, and you'll figure it out by next winter or maybe winter after that

If the bike has a spring plate (AKA grenade plate) in the clutch it would be a good idea to get rid of it, if they come apart (and many have) they do serious damage to the clutch basket, plates, etc.

If I knew what that was it might be a debateable topic.

What bike are we talking about?

You want it mechanically sound first. Then ride it a bunch and figure out what you need.
