Performance parts only pay off when the engine is set up to use them. A cam, a big bore kit or a new exhaust changes how much air and fuel the motor needs, so the setup has to follow the parts. Syndicate Cycle does engine and performance work on Harley and V-twin motors in Oroville, and you get a real timeline before anything comes apart.
In California, a performance build has to work on paper as well as on the road. Emissions-related aftermarket parts need a CARB Executive Order number to be street legal, and each EO covers specific makes, models and years. Motorcycles built in 2013 or later also need an exhaust that carries the federal EPA noise label. Knowing that before buying parts saves money and trouble later.
Once the parts are picked, fueling decides whether the upgrade actually works. More air moving through the engine needs more fuel to match, and an engine left running lean runs hotter, which is the last thing an air-cooled twin needs on a valley summer day. The tune has to be matched to the hardware, not left at stock settings, and the result gets checked rather than assumed.
Bigger jobs like a big bore kit or a cam swap also come with a break-in period and a follow-up check afterward. You see the whole plan, the parts and the timeline before the engine comes apart, so there are no surprises halfway through. The first oil change after break-in matters more than most, since it carries away the fine metal from new parts seating in.
We also carry HardDrive and Dunlop, plus exclusive suspension components. If we do not have the part on the shelf, we will get it in.
Longer than a tune-up. It depends on the job and on parts, and you get a real timeline before anything starts.
It is shorthand for how far a build goes, usually starting with intake, exhaust and fueling, then cams, then displacement. The exact parts depend on the bike, so tell us what you ride and what you want out of it.
It depends on the part and the bike's year. Look for a CARB Executive Order number for emissions, and on 2013 and newer bikes, the EPA noise label on the exhaust. Unsure? Bring it in and ask.
In most cases, yes. Those parts change airflow, and fuel delivery should be adjusted so the engine does not run lean.
