The only trans I took apart was the 4speed on my 1978 FXE. It would not stay in 3rd gear. This was may years ago and I remember having to change a shifter fork and replacing the "hats" (might be the shifter fork nipples) on the shifter forks. The hats rode in the channels of the ratchet top. The first time I looked at it I didn't find anything that looked so bad so I closed it up and put it back in the bike. Needless to say I still didn't have 3rd gear. A little wear can sometimes make a big difference.

The OEM gear ratios in your 5 speed trans will never change by changing anything in the primary or secondary drive. 5th gear will always be 1:1 but by dropping the compensator sprocket 1 tooth you drop you primary ratio which will affect your overall ratio in each gear by 4 1/2% so Stock is 10.93 so dropping to a 23 would change 1st gear ratio to a 11.40 which is what you said you currently have. so the rest of the gears would be
2nd-7.77
3rd-5.63
4th-4.33
5th-3.52
Ist question is are you definitely going to the Baker DD6? If so I called Mark and the only compensator gear they offer for that setup is the 27 tooth so here's the listings for their DD6 setup. with your 23/37-32/70 setup. Way Harry for the street..
1st-13.26
2nd-9.01
3rd-6.58
4th-5.06
5th-4.04
6th-3.52
Now the Baker DD6 with your stock setup 24/37-32/70 1st would be sick(very short) and your 6th@1:1 is still a 3.37 Just like it was with the entire OEM setup...Not really great for cruising.
1st-12.71
2nd-8.63
3rd-6.31
4th-4.86
5th-3.88
6th-3.37
Now with the baker DD6 and Baker 27 tooth compensator so 27/37-32/70
1st-11.30
2nd-7.67
3rd-5.61
4th-4.32
5th-3.45
6th-2.99
So yes the Baker DD6 with the 27 tooth compensator is a tad less gear than the 23 you upgraded to. I don't think your gonna like the OEM setup with the baker DD6 it's a 16% jump over OEM. It's huge and am not sure your gonna like it. There are 2 people that I know that race well one still does and you can call them and run the numbers by them to get a solid answer. Kirby Apathy 386-873-4427 or Scott Palmer 315-495-6650. One benefit is that you did pick up a nice cruising gear in 6th...
There is another way to increase the ratio over your 23 tooth setup and still use the Baker DD6 and still be streetable... First here's the numbers 24/37-32/65 this is a 4% increase over your 23/37-32/70 with the OEM trans that was 4.5% over stock.
1st-11.81
2nd-8.02
3rd-5.86
4th-4.51
5th-3.60
6th-3.13
So now to get this setup you will have to change you rear pulley to a 65 tooth and can be found on ebay relatively cheap. Also you would still need to get a new belt that would have to be 2 tooth smaller... The rule to thumb for pulley to belt size is 2 tooth on the pulley to 1 tooth on the belt.. So it's kinda in between 2 and 3 tooth on the belt. I believe your OEM belt is a 130 so a 128 should do it... But check your service manual... you'll also like the 3.13 cruising..... Just so you know this setup is an 8% gain over stock...
Good luck.....

Stock tranny on a '95 Heritage.
Last year my tranny started acting up.
What was happening was I would shift into 3rd or 4th (don't really remember now) and I would let out the clutch, twist the throttle and the tranny would act like it was in neutral for a second then slam hard into whatever gear I was shifting into.
At the time I wasn't really worried about it as I had a DD5 Baker sitting in my shed so I just swapped trannys and called it good.
Now I'm kinda board and was gonna look into the OEM tranny to find out what it could have been.
Anybody got any ideas?
Keep in mind I've never opened a tranny up (of any kind) in my life.
Or would it be best to just take it to the shop (I don't have all the tools for a tranny) and let them look at it?

The shifter adjustment on the left side of the box was out probably, With the lid off, the selector pin has to be centred in the selector fork.

It was just a hair off but the biggest problem seems to be the wear on the shifter drum and lack of spring tension in the shifter pawl.

The 3.13 final would be close to a OEM touring gearing of 3.15 and good for cruising. I think Hotrod is using close if not the same gearing as mine letting the OD6 being a slight overdrive in 6th but lower in 1 thru 5.
That S&S is solid enough to hold up to a lower final area but will eventually start eating at you thinking about the larger mass of moving parts and $6000 cruising in the 70-80 mph range for a extended time. Your big motor WILL have the ability to overpower a higher gear ratio especially in a light bike in the lower gears. Too low of gearing will rev a big engine thru it's power removing it's strength of torque. Think you should target that final gear for interstate cruising rpm and let the motor do it's thing in the lower gears, believe it or not, it won't need a gear drop in 6th at 3.13-3.15 when passing, those big motors are happy loaded, I've found myself accelerating hard in 6th gear thinking it was in 5th and trying to pull 6th later saying WTF, those big engines defy normal.

The next thought going through my mind is it's gonna cost around $200 to fix this tranny.
After I fix it it'll go back into a box and stuck on a shelf against future possible need.
I have a Baker DD5 in the Heritage now which will probably outlast me.
I have an OEM tranny in my '94 FXSTC with only 60k on it.
Do I fix the tranny now or later?
