What issue? Address what you may be asking? Good questions! With over videos uploaded and the vast majority of those relating directly to performing some kind of upgrade, customization, maintenance or repairs on motorcycles two questions surface with some frequency. These two questions are specific questions that should not be asked. These questions if asked then bring a question I want to ask back.
The two questions I am referring to are: what size socket do you use for bolt, nut, part hereand what are the torque specifications for bolt, nut, part here.
The first question I want to ask back is: why are you working on your bike without a service manual? If you were referring to a service manual for your specific brand, make, model, and year of motorcycle you would have the torque specifications at the flip of a page and would not be asking for those values. When I get this question it is not one I will answer, and I would encourage other viewers not to answer their question either. I had a guy tell me the torque specification on one of my Street Glide Special videos was wrong because the torque value listed in his service manual was different for his Road King.
Well, duh, yeah, different year, make of bike, hell, even a different size of the engine! I guess he thinks his bike references the final word on torque values worldwide for each and every motorcycle….
This type of issue is why I generally do not mention specific torque specifications and why I will not answer this question when asked. To validate this argument I want to refer to a critical drive component on the motorcycle: the Compensating Sprocket.
The first service manual picture is of the final torque of the compensating sprocket bolt on a Street Glide with a The next service manual picture is of the final torque for the compensating sprocket bolt on a Street Glide Special with a ft-lbs. This is a perfect example on a critical drive component as to why you should not be asking about torque specifications. You should be using your service manual for your make, model, and year of bike to obtain the correct values.
The other issue is when the question is asked about the size of the socket or wrench needed for bolt, nut, part here. It never ceases to amaze me on how many people seem to think that every nut and bolt on every model and year of bike are the same.J A new primary cover gasket must be ordered separately for the proper installation of this kit.

View interactive image Figure 1. Caulk Gun and Adapter. Clean primary cover with PJ-1 or equivalent.The Harley-Davidson Evolution engine comes with cubic centimeters or 80 cubic inches and is used to power the Touring, Dyna and Softail ranges of cruiser motorcycles.
The torque produced by the engine depends on which bike it is fitted to and the bike's type of fuel induction. The Evolution engine of cc displacement has a bore and stroke of 3. The compression ratio is 8. The engine is a V-twin with the two cylinders at a degree angle to each other.
It is four-stroke, which means the pistons take four strokes to complete an engine cycle. Torque is measured in foot-pounds in the U. The torque produced by an engine is a turning force around an axis measured in foot-pounds. For example, if a force of pounds is applied one foot from an axis of rotation, the resultant torque would be foot-pounds. Torque is related to horsepower, and one horsepower is actually equivalent to foot-pounds a second.
Torque is also related to work, which is measured in foot-pounds also.

However, torque is distinct from work, as work involves the movement of an object over distance, whereas torque acts on an axis where distance is not necessary. Torque also changes with engine revolutions, which is why it is usually specified at a particular rpm when it is at its maximum. The torque of an Evolution cc engine depends on the motorcycle it is fitted to.
For the Dyna group, the maximum torque produced is 79 foot-pounds at 3, engine revolutions per minute.
At the same rpm, the engine produces 76 foot-pounds in the Softail group of bikes. In the bikes with a carburetion system, the Evolution produces 77 foot-pounds of torque at 4, rpm, and in the ESPFI touring bikes, maximum torque of 83 foot-pounds is developed at 3, rpm. The equivalent torque in Newton meters is Nm for the Dyna group and Nm for the Softail bikes.
The carbureted Touring bikes produce Nm and the fuel-injected models Nm.

Mechanic Joe Minton warns that over-tightened bolts are likely to fail eventually, which is why it makes good sense to know the recommended torque specifications and to employ a torque wrench.
For many Sportster fans, the famous 42 foot-pounds of torque needed to tighten the cylinder bolt is a figure seared into the imagination from an early age.
Harley stator torque specs
Minton explains that Harley-Davidson spent a great deal of time arriving at this particular figure. He recommends that if you want more torque, you should hone the cylinders and tighten the torque plate bolts to the same specification.
