??? On a Cam swap for 06 ultra

I'm not looking to go wild with a big bore kit....yet... but an welcoming any opinions and options for a cam swap on my 88ci ultra classic. I do have a stage 1 intake and exhaust with a download right now and I know I will have to get a tuner. But I just wanted to hear what other people have done and what your recommendations are... I thank you in advance.
God Bless
Michael

I did a 95" with SE 203 cams and I am happy with results.
I would recommend doing cam tensioner upgrade while in there.
Includes hydraulic tensioners and improved oil pump.

S&S .510`s are a good choice

If you are looking for a great jump in torque, in that touring machine, we would suggest an Andrews 26.
Then, when you want to step up to more, bore to 98", and with a good set of heads, you'll REALLY wake that up.
90 plus hp and well over 100 ft/lbs, usually all in by 3500 rpms, while still being at only 9.6-9.7 compression.

Andrews 21G

A few years ago I had an '03 Ultra that I put an Andrews 21G cam in. That REALLY woke up my 88". If you don't plan to put in a bigbore kit to go to 95", then that is definitely the cam I would choose. It will still work well with a 95", if you choose to install a bigbore kit down the road, but you will need to retard the ignition timing a bit because it will want to ping. 21G is an excellent way to go if you are just trying to wake up your 88" without breaking the bank.

FYI- The "G" designation is "gear drive" which eliminates the chain drive on the cams. You can also get a chain driven version of the cam if you don't want to convert to gear driven. I converted to gear driven just to eliminate being concerned about the cam chain tensioners wearing out. The gears do whine a bit, but not much and I kinda liked the sound.

What would be the difference between the 21 and the 26 Andrews cams? I like the low to mid torque. For stop light to stop light fun but i ride a lot of 2 up.... and its a heavy bike 2up with gear... just kinda giving y'all an idea of what I'm looking for... thank you in advance for any help

The 21 makes it's torque earlier in the RPM band than the 26. Both are good cams, but my personal choice on an 88inch engine would be the 21. Especially on a heavy bagger and riding two up. I'd want a little more compression if I were running the 26. I was extremely pleased with my 21 on my Ultra. Lots of smiles per miles.

Lifted the below comparison from the Andrew's website:

216321 21H 10/30 100 220 255 .498 .134 Stock Bolt-in cam: 07 - 13: More torque for all around riding,
40/08 106 228 264 .498 .121 heavy bikes, stock comp. ratios and pistons. Similar to
#23 cam for EV80. (1700-4800 RPM).

216326 26H 11/35 102 226 262 .490 .138 Stock Bolt-in cam 96 - 103 inches and stock compression ratio.
41/09 106 230 266 .490 .120 Great for two up touring, this cam will add torque and HP
at lower and middle RPM ranges. (1800-5200 RPM).

You would probably be fine with either cam, but my experience with the 21 was very fun and satisfying. You will find plenty of proponents for both.
