The people that I bought the bike from said they changed the oil, (I bought the bike used with 2,500 miles), but I decided I would do it so I knew for sure. The dealer recommended the Harley full synthetic 85w-140 for the transmission and primary, it is hot here in the south. 20w-50 screamin eagle syn 3 for the engine, who knew an oil change would cost so much. I can do my car for $30 with Mobile1. I have not ridden the bike yet, (just finished it tonight), but some people said they did not like certain fluids in the primary because of the way it made the clutch behave. All 3 drain plugs were not seated or tight. Nothing on the magnets for the engine and trans and minimal on the primary. The stuff that came out of the transmission was a blue/green in color, never have seen that before.

Be careful, and don't be Joey over torque, when putting any of the drain plugs in. They are all o-ring sealing and don't need a whole lot . I had a buddy crack his oil pan doing this.

With over 50 years as a professional mechanic behind me, I`m going to strongly disagree with this way of thinking whether it be cars, motorcycles, aircraft.
The only way you are going to improperly torque a fastener using a torque wrench is if you don`t know how to use it or set it.
There is never a legitimate reason to tell someone not to use a torque wrench.

Who says I used a torque wrench, I just called out the spec. and said it was more than finger tight. I used a 3 foot breaker bar and pushed on it with my foot with all my might. I am no Knoxville **** kicker.

I have a stock 107 but it looks like your bike has some substantial up grades. My bike has 2,800 miles on it and I have bought the stuff to go in there and look to see if it has over tightened, I hope it has not. After reading and looking at this issue I thought it was worth looking into. After looking at the different makes of manual adjusters I liked the design of the baker the best and if I am having the tightening issue this will be the one I buy. I was at the dealer today and asked if they had a Screamin Eagle manual and all they make is the auto adjuster for the M8. I am not having any issues that I know of but will find out when I look. I will report back with my results. What is the spec. for the chain play and I am curious as to the miles you have on the bike?
Just short of 20K, but a ton of mods, so possibly self induced? Years of wrenching and running shops, I don't rule it out, every significant mod costs somewhere else.
I used the spec right out of the manual, and like posted above, checked 5 spots.
I am going to try and get this done this weekend
