88 CI to 98 CI UPGRADE

Solution is rivera primo clutch. Lighter than stock pull and double the friction surface.

JOhnny there are two approaches to increasing the ability of the clutch
to handle the extra power.

1) Increase spring pressure (what you did) this works to add force
to the plates to hold them from spinning under power, the downside is
that you increase the force that is required to actuate the lever

2) increase clutch plate area, Rivera plates are twice as wide in the
area where the friction material is than the stock HD plates, so you have
double the clutch area, same for PD's suggestion another plate, more friction
material

Rivera and others increase the material area and you have to press out the inner
hub on the clutch assembly and put in their inner hub, it's easy to do and then it will
accept the taller (wider) plates (not thicker) with a better spring that allows you to
maintain an acceptable clutch lever pressure.

I ran the HD SE Drag clutch sucker would hold anything but the force
required to move it was a PIA in traffic. Popeye forearms optional..

HD SE plate basically does the same you will get used to it over time
and it will seem normal, as long as you are not doing the main st crawl
you'll forget it's there but you will still be using more force.

There is also a new trans cover plate lever that reduces pull that you
can put in with the HD spring but then you're taking apart the trans side cover,
dropping exhaust etc.

One other thing you can do is swap out the cables for a teflon lined SS braided
cable this reduces drag and pull as well

OK lets say its related to the cover (doubful) but possible, if in fact the football cover which is larger and thus perceived to be restrictive over the open filter then the cover made it richer, so I would simply adjust the air mix screw to see if that helps.

my guess is you are getting to the point you need the tune done and you want to do that using the cover you'll ride it with.

Stick with muti viscosity, 50W will be 50Wt at cold temps or hot
Twin cams have very tight tollerances and lots more oil ports and passages
than the old Shovels which were loose compared to the CNC stuff made today

you need to be sure that lubrication gets moving quickly to all the bits
that need it and that 50Wt will have to warm up.

a 20W-50 will flow faster at the cooler temps in the winter, spring and fall
and at cold start up, getting oil to the valvetrain, lifters, cams quicker.

Nobody said it was wrong, maybe you should check your reading skills
the manual gives you a scale and range and if you look really close
you'll see it overlaps on temps.

You'll also see that 20W-50 covers the majority of the ranges and
is the recommended oil by HD for good reason, what oil came in the bike
why, 20W-50, because it covers the majority of temp ranges
in the world where they ship bikes, Syn 3 - 20W-50, the oil HD
sells the most of, 20W-50 non syn.

From HD's web site

All Temperatures
Harley-Davidson recommends SAE 20W50 viscosity grade oil for "all temperature conditions," according to the Harley-Davidson website. The SAE 20W50 oil covers the biggest range of operating temperatures and is ideally used in ambient temperatures ranging from 60 to 80 degree Fahrenheit.

Low Temperatures
Low temperatures, those of 40 degrees Fahrenheit or less, call for Harley-Davidson SAE 10W40 H-D Motorcycle Oil. Harley-Davidson classifies this oil viscosity as "appropriate for low temperature climates." The SAE 10W40 H-D Motorcycle Oil is formulated to guard against low-temperature problems such as erratic idle and lack of power.

High Temperatures
Harley-Davidson recommends SAE 60 H-D Motorcycle Oil for ambient temperatures above 80 degrees Fahrenheit. SAE 60 H-D Motorcycle Oil is formulated to prevent engine overheating in high temperatures. Since Harley-Davidson engines already run warm, it is important to guard against overheating by using the proper oil in high-temperature conditions.

When we extract the annual temp data over the past 20 years which includes the global warming, cooling, cow farts, eco corn fuel crap.. Which shows that on average you don't hit 80's and sustain them, oh you could have a 100 degree day but on average MN just doesn't break the top end of the 20W-50 range recommended by the Manufacturer
