Hate to add more of a question than an answer but my 04 RG had a six speed "overdrive" from HD with a six speed cover. At 70 mph, I tached 2600 rpm... same as the SERG but now they call it "cruise drive." If it's not identical, it's damn close!! I'm betting the standard cover fits but it would not be hard to compare........

Actually the 6 speed overdrive is just that, an O/D 6 speed. This is nothing more than the same gear ratios from the 5 speed and then with the .86 O/D 6th gear. The new "Cruise Drive 6 speed" is NOT an O/D trans, but just a slightly closer ratio gear set with a lower low gear, but a 1:1 final gear. They then make up the "gearing" or "O/D" simulation by changing to a higher ratio (closer to 1:1) primary sprocket set up. Although as the "other" thread has said, they missed the mark on just how low low gear should be. But still the Cruise Drive is not an overdrive 6 speed.
I think I said it in my ealier post, but the SE 6 speed is not the same 6 speed that's in our '07 and newer SE bikes. Just like the new SE cam plate with bushings is not the same cam plate that they use in our SE 110" motors.
I'm leaning towards some type of clearancing issue inside the cover that is required for the retro 6 speed gear set requiring a new cover. Externally they appear the same, but internally they MAY be different.
I know that we all have doubts about the MOCO and their reasoning sometimes, but I've looked back through my last two P&A catalogs and with different retro parts kits and if you don't need something they just didn't add it because they wanted to sell it. As an example, the new SE cam plate. They don't say you need a new oil pump or new cam set to use it. If we took the 6 speed scenario to the cam plate, they would say "must have cam set XXXXX-XX and oil pump XXXXX-XX to function properly. So if they COULD gouge us for "extras", they would there too, just my opinion. I think I may be a bit naive when it comes to the MOCO as I'm "new" to the family and have no longterm experience to base any negative opinions on. Even so far on my '08 SERK, I got a great archive book, the bike runs great, handles great and looks cool.
I think someone like HD-Dude could step in and give us a little background on this.
If I were doing a SE 6 speed gear set change and had to have it done for a trip, I don't think I would guess that the stock cover will work. I may be waiting for a while to pick up the 6 speed cover.
Of course this is ALL just my opinion with some facts thrown in on the two different types of 6 speeds. I think we need to have someone that's done this verify to the need or no need for a 6 speed cover.
I asked this in the "other" thread, has anyone heard what the new Baker 7 speed gear set is going for? Just wondering.
Sorry to keep mudding the waters on this...
