I ran 203 cams in a stock 88" twin cam when they first came out. As a matter of fact, these cams came out before the first 95" kits. Cams alone destoyed the bottom end. When available (about 6 months later) I installed the 95" kit with 9.5:1 compression. Did the stage II flash and had White Brothers E Pipe, 2-1, 12 discs. Bike ran GREAT with that combo.
thanks

Let me say this for those on the forum who this topic doesn't fit because they are not running 203's and that is if ou are wanting to chim in on this thread you can contribute by telling us what combinations would do the best for us in having these cams that we choose to keep and run,that would be greatly appreciated also.

I ran 203's and 211's in my dyna with a high compression 95" kit, mikuni carb, and an ultima six speed. The 203's had a lot of low end grunt and I could spin the rear tire in second gear just by cracking the throttle. The 211's were more mid range power but with about 10k miles on each, to do it over again I'd go with the 203's. Plus you can get them on ebay fairly cheap.

I have enjoyed my 203 cams on the Ultra. She has good manners under 3 grand so she is not real jerky or loud. Some state that other cams have a better bottom end but with 3.37 gearing and a 6 speed, its not a problem. This is a big bike with 280 extra pounds on her and she goes just fine. Some day with head work, she'll get dialed in but for right now; shell stomp the $hit out of a stock 96...

I want to address those on the forum who have the 203 cams in their bikes and who are keeping 203 cams in their bikes what are some of best combinations using these 203 cams to get the most out of your harley for horsepower and torque?
I would like to hear moslty from those forum members with 203 cams only and who have not and will not be changing from 203 cams out of their bikes.

Honestly, your thread is like asking for folks who bought a Yugo and plan on keeping it what they've done to make it better.
My reason for denigrating the SE 203 cams is based on riding with buddies who have them in HD's 95" big bore kits and their Touring models are slower than my otherwise stock 88" engine with Head-Quarters HQ-0034 cams, Rinehart TD's and SE a/c. Interestingly, all of their dyno numbers are similar to yours: about 90 hp and about 100 tq; while mine dynos at basically 80 or so hp and 90 or so ft. lbs. tq.
As for headwork, one of these buddies had BigBoyz headwork on his 95" build (RK Classic) running 10:1 CR and his bike was slower than mine. He promptly purchased HQ-0034 cams, spent a lot on a tune from a well-known tuner, and his bike was very marginally stronger than mine.
Sorry to interrupt your thread.

Please can i just make a thread about 203 cams without it being negative. Some are happy with 203 cams so i am sorry if that bothers some on here but this is the thread i wanted to do.

I also like the 203 cams for the highway when your riding with a group of riders of 10 or more because your speed when everyone is riding together you are riding very strong cruising at 80-85 mph which is mostly you run on the highways with that many riders. I know in october the first week a local bike club will be riding to NC and has invited some to join them from maryland were their will be over 80 bikes going down the highway so those 203's will do nicely in that situation also.

I have the 203's in my 2000 Heritage. At the same time, we put a Thunderheader on it. I forget my exact #'s. Around 80 HP, and 86 or 88 lbs of tq.
It goes pretty good for what it is. Put it this way, I haven't had too many people blow smoke in my face.
I (demo'd) an 07 SG when they 1st came out. It had SE slip ons. Kinda sounded like two lawn mowers racing but ran good. I would say my Heritage is a tad faster than that 96". Certainly more torque. The T/H and those low end cams are a good combo. I'd like to see how they'd do in a 95" and maybe a Mikuni.
I like em. Only advise I have is (if) you are going to run 203's check those tensioners OFTEN. I did my cams @ 9K miles. The inside tensioner was 1/3 worn. If I recall the inside chain runs both cams. The outer is cam to cam. (Correct me if I'm wrong)

What did it feel like when you were riding with a group of others on the highway?
