After researching the HDF I pulled the trigger and had the cam chest upgraded to hyd and added the 203's. This combination rocks, pulls hard right where I like to ride, no downshifting on hills or to pass. It also seems to be getting better mileage. And NO POP on decel, which previously I thought was normal. Best mod so far!

****Had bike dyno tuned today by a guy who really knows SERT right here in the 661, printout attached, AFR was fat in mid range which I'm hoping was causing my reduced mileage. She pulls hard 74 hp and 85 tq.

 

Someone needs to make a "this thread is worthless without dyno sheet" icon.

But in all seriousness, congrats on your mod! I'm sure it's way more fun to ride now!

 

Did the Andrews 21's. You are right, cams are a great mod! Lots o bang for the buck!

 

Did you dyno tune it? Programmer? Doing 203's & cam plate on my 00 in a couple weeks. If funds allow will install 06 or newer heads & 95".

 

If you have not bought the 203 yet , seriously look at the 204 instead. The 203 are a EPA compliant cam and you are doing all the work for a minimal return. The 204 will pull a lot stronger at all rpm than the 203.

I used 204 in my 05 Fatboy and they were great improvement. Im looking at cams for my 103 RG and Im leaning towards the 204 again ove the 255

 

I already have the 203's. I do a lot of backroad riding they may be ok. But if I can find some 204's for cheap...

 

Most of my riding seems to be @ 2500-4000 rpm

 

No dyno tune, running a SERT stage 1 map. Funds are tight, thought I would see how it ran before doing a dyno run. So far I'm very pleased.

 

Sounds like you gotta a winner, I'm hoping mine don't create any other issues.
