Here's my current gearing and what I'll have with the Baker Grudgebox, and with the rear drive chain gearing I have to install. 1st, 2nd and 3rd gears are just a touch lower, and 4th, 5th and 6th are just a touch higher. Almost like I've been planning this.....
Main difference will be a solid transmission again, and tougher. Also with the chain drive, and when the S&S 640's and higher compression pistons go in as well, I'll actually be able to really beat on it. I've actually not rang it out really hard as the transmission is a bit soft with almost 70k hard miles, and the rear belt would snap if I really hammered it.

it will definitely be a wheelie machine with that gearing. :chop:
I did the 24/51 rear gearing and feel the GrudgeBox "strip" gear ratios really tamed the bike down to the point it's sort of boring again.
I want to keep things about where they are now. First three are a bit lower which will help acceleration, last three are almost the same as now, but a touch higher. With the 49 tooth clutch shell, and the rear wheel 55 tooth, I think it'll be a good setup for me.
Updated the sheet to calculate the RPM change difference, and the gear ratio changes, those shown in percent change.

Ohio, would this be a similar ratio change with a game changer comp and a grudgebox VS a 49tooth clutch basket and grudgebox?
On what bike, year and model?
I ran the Baker 6sp OD box with 24 frt 51 sprocket with the 3.37 primary, 1:1 5th gear gave me 3.37 and final OD gave me 3:15 final was a great set up.
Next to no difference. Left is 49 tooth, right is game changer.

Thanks a lot.
Similar case here, I thought the GrudgeBox was too soft with stock primary/secondary. I added a game Changer and felt it improved at 3.05. But since added 54 rear sprocket for 3.23 and I feel it helps out if the hole yet doesn't overdue it up top on the highway.
Awesome.
Looks like the gearing I'm looking for. Let us know how it feels when you get some miles on her.
One of two Baker shipments arrive, the 33715-85SA truss style shift lever assembly came today. This are really made well. Just need the transmission to put it on now.

Ohio, That is indeed a nice looking unit, I was looking at one, but didn't order one yet. Waiting on the DD7 I ordered form my local indy. I tried the stress of doing Bakers BF last year and missed(wound up doing their Trap door to get me thru the year). This year I just told my Indy to order and price it to me how he needed (treats me way more than fair but needs to eat also). After looking at your shifter you received I think I will have him add it to his next order. 08 RG, Stock gearing( 32/66 rear) slightly high for mountains and trailer towing even with the 117. Last season I ran 31/68 but with the lower 1st in the DD7 and the spacing I am thinking of going back to the 32/66. Thoughts?
I think that would be a good idea. Your first six gears will be lower overall than with the HD six speed and stock gearing. And seventh will be the same as OEM gearing with the HD sixth gear.

Side by side, this is what the overall drive train gearing looks like.

The DD7 gearing is just about perfect IMHO.
I put one in my 07 RK after ripping six teeth off of 3rd gear in the POS cruise drive tranny.
The difference the DD7 ratios make is huge. Before I blew the stock tranny, I was trying to decide what gearing change I should make to lower the lower gears so it didn't feel like I was always starting in 2nd gear.
With the DD7 that problem was solved without having to loose the stock top gear for high speed cruising.

Ohio,
Thank you for putting that in a spreadsheet, nice to see data side by side.
Kinda along the same lines as my 02 was, SE 6 speed over drive, with the 3.37 primary set up. Good down low and thru the gears with good manners running up top on the hiway. Very much looking to forward to trying the DD7

I Agree,and shift points seem to be more evenly spaced,and made my bike faster,,,,,,,,,,. :hyst:

Yes I think seeing side by side, and then knowing how the bike is for you now or with the previous gearing helps determine where to change things for better results.
Ohio, could I trouble you to maleone more change in the graph?
Currently a 2013 with game changer, stock trans and final drive
Installing a grudgebox and thinking of a 30 tooth trans pulley and returning engine sprocket to stock.
Will this lower ratio more than the game changer....or less? Thanks for your time.
2013 Touring
This weekend I can, I'm traveling till then.
That would be great. Thank you.
Left is 32 motor, 46 clutch, 32 transmission, 68 rear wheel, HD six speed.
Right is 34 motor, 46 clutch, 30 transmission, 68 rear wheel, Baker Grudge Strip
Gearing is higher all across the board.

With the pieces shown, does anyone know who makes the broach to cut the splines in the end ? might be able to re-cut a worn out shaft, or make a custom one.
Thanks Ohio! Appreciate your help.

So..... the truth is, the Grudgebox is not a myth..... they do exist..... :doh:

I have one on my bike and I like them too. The only drawl back is that they cannot be removed/replaced without taking the inner primary off, like you can remove the stock shifter arm. The Baker is just a tad too thick.

Mine shipped today. It's been on order for 3 months now.
I think it's more like 4 months isn't it? :crook:
Yes about four months. I ordered November 21st, I believe, and I just got an email today that it shipped.
Were those part of the Black Friday sale?

I know mine was. They claimed they were waiting on one gear over a manufacturing glitch. The part has been received in the past week and they are being assembled and shipped as completed. Pretty well a 4 month wait.

Yes. Price was way too good to worry about how long it took. So I shot guns all winter rather than work on my bike. That's lots of fun too.
