107" kit with cams and 10.25 or add cams & heads to my 103"?

[Ketch]

I currently have a 2016 RGS with stage 1 (Rinehart Slimline, PM air intake and FP3). I want to go up a bit more in the torque. I typically ride in the 2,500 to 4,500 rpm area. I'm trying to get the most for my limited budget. Thanks.

[dsvracer]

it is the heads that make the power and it is the cam that dictates where in the rpm range the power will be.  heads and cams should be first in making more power.   jmo

Staying at a 103" configuration, combined with the proper cylinder head work/cam combo, can yield very good power indeed.

What is your budget?

Toss in a set of cams wil give you a nice gain. Head work more yet. Once you pull the heads the budget often gets tossed out the window...might as well........

[koko3052]

Unless you have a  load of miles on it, just cams....if the budget is good then cams & headwork.

Just getting a dyno tune by someone competent and ditching the FP3 would probably help

I'd really like to stay at or under $2,500 for the cams, headwork and the complete tune. Is it possible?

Rough estimate at 103
550.00 should get  you PV license and tune
Lets say 650.00 for a set of heads from one of the fine vendors here on the forum
75.00 for gaskets
125.00 S&S standard lifters
30 bucks feuling tensioner refill if necessary
20 bucks inner cam bearings
Cam? 300.00
S&S clutch spring 30 bucks
stock pushrods  0.00
That's 1780.00 and I am sure I forgot a couple things
At say 70 dollars per hour that leaves over ten hours for labor.  I don't see the problem but I would mention that an additional 5 bills for a set of 107 cylinders/pistons will only be that 5 bills and all other things remain the same.

That is solid info right there.

[prodrag1320]

if you do the work yourself,you can easily do a nice 107 build for 2500.00

[Don D]

Or a bolt-on 110.

[Hossamania]

Or a bolt-on 110.

That was my first thought. If going to the trouble of 107, might as well bolt on a 110, it's just as easy.

110 and done . best bang for the buck no head work needed to make 110/120

[sfmichael]

I have a 2013 Street Glide 103 with cams, heads, and a tune and it runs very strong - quite a bit better than a 2016 (which actually has a decent cam from the factory)

The 2016's respond quite favorably to just a dyno tune with a good exhaust system. Good dyno operator is essential.

That being said I will be bumping mine to 110" in the near future, I can't leave well enough alone

...I typically ride in the 2,500 to 4,500 rpm area. I'm trying to get the most for my limited budget...

That would be a Stage II...Cams and a thorough and competent tune.

Cams: Use CR-570-2 or very similar configuration.
Tune: Powervision flashed by a well vetted and part-throttle experienced tuner guy.

That'd be doable at 103" or at 110" on the OPs stated budget. He could probably even afford a little head work too.

From everything Ive seen a 110" and Cams and tuner.

[Ketch]

Can I use my stock heads if I go with a 110" and cams? I'll have it tuned.

Yes- lots of budget builds out there with that combo. Make sure you have correct clearance & springs for the cams chosen- if the cam card says "bolt in", you should be golden.

I couldn't imagine pulling the heads and not at the very least doing a valve job and new seals. I'll take a 107 with ported heads any day over a 110 with stock untouched heads.

[Tommy D]

  Bob did a 107 w/heads for me, couldn't be more pleased with overall drive-ability & performance

[Winston Wolf]

If a guy stuck with the cr570-2 mentioned, and left it at 103" but ported the heads and bumped the compression to 10.2 ish, I would assume it would be very strong in the low end?  I'm thinking of trying it to squeeze out some more low rpm roll on punch. Not really worried about the peak HP number, but wanting to maximize the 2500-3500 range.

[PoorUB]

I hate pulling heads just for the clean up and port. If I pull heads I tend to go deeper!

I bet you will be pleasantly surprised with tossing in a set of 570-2 cams, leave the heads on, and a tune. I did it to my 2016 Limited and it is a totally  different  motorcycle.
