How much compression should a 1200 Sportster have?
Compression test results vary on stock models but, typical rule-of-thumb is a minimum of 120PSI for 883 engines & 150PSI for 1200 engines, but on 2004+ the 1200 engine minimum should be 180PSI.
What kind of shocks does XL1200S Sportster Sport have?
Besides the usual adjustment for spring preload at the rear, the 1200S offers adjustments for spring preload up front and damping resistance at both ends, both for compression and extension. The piggyback-style reservoir shocks and 39mm cartridge fork are same ones used on previous XL Sports.
Is the Harley Davidson XL1200S a sport bike?
That situation will probably strengthen as Harley’s new Sportster-only factory in Kansas City comes on line next year. And if Sportster Sport is a bit repetitive, it’s also a great concept. No, it’s not a sportbike, just a Sportster with some extra elan. It’s the Harley that zigs.
What’s the torque increase on a Harley Davidson 1200?
Harley says that the changes boost the 1200’s torque by an average of 15 percent throughout the range and almost 10 percent (78 versus 71 foot-pounds) at 4000 rpm. All ’98 Sportsters have a more efficient oil pump to improve scavenging from the dry sump.
What makes a Harley Davidson 1200s a Sportster?
If ever a bike embodied the name Sportster®, it’s the 1200S Sportster Sport. Black ceramic-coated pipes, hot cams, and dual-spark ignition send a strong performance message. As do the triple disc brakes and premium, fully adjustable suspension.
What makes Harley Davidson XL1200S Sportster Sport Special?
In addition to the high-tech electronics, the Sportster S benefits from a point more compression (a 10.0:1 ratio instead of the standard 1200’s 9.0:1), less restrictive mufflers, and special camshaft profiles.
What’s the compression ratio on a Harley Davidson 1200?
The combustion chamber yields a 10.0:1 compression ratio and allows quick burning of the mixture, even with a single sparkplug per cylinder; but Harley has given each head (on the 1200S only) two plugs. This exemplifies the difference in tuning philosophy between The Motor Company and its Buell division.
What kind of head does a 1200 Sportster use?
This is one of the most common Sportster heads you’ll come across, as it came on every 1200 Sportster from 1991 through 2003, except the 98-03 XL1200S model. Unfortunately, for performance applications it’s not a particularly good head, as the ports are turbulent and the chamber is not, which is just exactly the opposite of what you want.
Is the Lightning head the same as the XL1200?
The Lightning head has the same ports and valve sizes as the XL1200 heads of the same vintage and as such they flow exactly the same. The Screamin Eagle catalog at one time claimed 8% more flow but I’ve flow tested lots of them and the range of results I get is the same as the standard 88-03 XL1200 heads.
