Totally disagree with this statement...that is why the bike has a shifter on it...you put in the correct gear for the speed you are riding...you use 6th gear only to reduce the high speed buzz...if you don't need it, you don't use it. 6 speed OD was the best mod I ever made to my bike....and I do not have a high HP motor...I would be surprised if my bike made 70hp on the dyno.

You have the floor Tom, at what speed does 6th come in and let's say 65 mph speed limit, can it gain speed out of 65 mph or needing to downshift with stock gearing and stock engine. Just trying to get a member some info in Evo forum fashion if you feel different

Can't remember which switch is what but one is a normaly closed and one is a normaly open, Ultima activate the HD switch opposite and nuetral light comes on when putting it in gear. Mia(John) has found that a Vrod switch will work in the Ultima so the thunder goes to him and I was refering to the gearset, don't know about a complete trans, they may have the switch hole moved.

As I continue my research, I found some very helpful information regarding compression ratio and cranking pressure. I found a lot of information through the night rider site with various links. Here are a couple of screen captures I did that had very good information about compression ratio, cranking pressure, shaving the heads, and gaskets. Hopefully someone else besides me can benefit from this.

completely disagree with the second picture. 180+psi does NOT mean an all out race engine.
I took my build a bit farther than most, and i'm sitting at ~ 195-200ish PSI CCP, granted I have mechanical compression releases, but rarely need them unless the bike is piping hot in the middle of the summer (at that point I use it to take the load off the starter). with a fresh battery she cranks and starts on the 1st or 2nd rev, and runs like a raped ape. pissed off my buddy with his CVO 110" streetglide when I ran away from him (he caught up, but it took him a while). with the timing and fuel set up right, compression is nothing to be afraid of, and IMHO its the best thing we can do to these bikes

Prot,
Bakers, compression, shaving heads - where going to have some fun with your bank account and while your reseaching engine componants put a S&S in that search box. Let's see S&S engine and a Baker DD6, you will never need Viagra
Jasper is right, 180 is good for the street, the Nightrider website is aging and today's engine builders have made some advances

The OP only complaint is a buzz at 70 and over,which an OD 6 speed will solve without any changes to the motor on relatively flat ground...if you need to pass a truck,or go up a big hill, downshift into 5th. People have the mentality that they have to shift into 6th as soon as possible and leave it there...not so. 6th gear is not for accelerating...regardless of how much HP you have. I run a Baker OD 6 speed, and also reduced the rear spocket 3 teeth over stock(51 to 48 with a chain) and run a relatively stock EVO...mild bolt in cam, s&s carb , stock compression,no head work...before I could not see out the mirrors over 65...now they are fine at 80
