Too full or bike has been sitting too long. Start it up a run it a while. Check oil level first.
Harley Davidson rates it at 90 HP at the crank. Most Dyno Tests show that stock bikes will make between 72 and 80HP at the rear wheel depending on the Dyno
The Crank Case Holds 3.79 Litres = to 4 US Quarts.
Shovelheads, as well as early Evos andall big twins back to Knucks all use a rotatry valve timed to the camshaft. This resembles a 1 1/4"drum about 3" long with a portion of it screened. Later Evos and Twin Cams use the "Head breather" system with the umbrella valves.
this bike holds 4 quarts of oil in the crank case always replace the filter
3 qts with new filter / 2.5 if you use old one but trust me put a new filter on its worth it
I just had my stock 110B dynoed. It made 83rwhp at 5200rpm and 100rwtq at 3500rpm. There is roughly a 20% difference between rear wheel and crank numbers.
The transmission and crankcase are one piece on a Sportster.
Compression is normally expressed in terms of pounds per square inch (PSI),...foot lbs would relate to twisting forces such as a spinning crank shaft. Two different animals.
160 foot pounds
No Harley Sportster has ever had a cam chain. The camshafts are gear driven, directly off the crank. No tension adjustment required.
No.
Crank case breather. The vaccum from the intake sucks air from the crank case to optimize performance. Particlized oil gets suck in. Nothing to be worried about. if you want to get rid of it. Purchase or build a catch can.
