I have a 1200R & would like to get into the high 80s or 90s in HP. What can I do-relatively cheaply $1000. to get there. I've done a few mods already and I'm at mid 70's...

1- port the heads
2- add cams
3- Cycle Shack Slip ons

That should get you into the 90s. Call NRHS, Zippers, or Headquarters.

Hi Dogman,
If you are running with no baffles, you could be losing HP!

Ported heads and cams would be less than $1000 on the low side. Each shop would have their own opinions about what cams to use. No one here has as much experience as the above mentioned shops. Call them and see what they recommend. I think you'd be happy with any of them. They'll be more than happy to talk to you and give suggestions.

Your might be a little short with a $1000 limit.

Nallin Stage 2 "Big Valve" Heads
$ 850.00 per pair using customer supplied heads.
http://www.nallinracing.com/headworkbuell.shtml

That leaves you $150

SE Cam Kit P/N 25197-04 (specific for the 04-05)
249 / 249 duration
.551/ .551 lift
http://www.surdyke.com/hd/catalog.asp
$ 263.75 from this source
$ 324.95 MSRP

I am not an expert, but I don't think the head work alone will get you the HP your looking for. Think your going to need heads and cam ... The parts selection needs to work as a matched "combo".

Puts you a little over your price ... I hope you are not planning on paying someone for the install.

NHRS will do your heads- Stage 1 $550. Stage 2 $850. Stage 3 $1100.

Surdyke HD has SE "E" .551 cams $263(on the internet).

Big valve heads aren't necessarily the ticket unless you are merely looking for high HP numbers. Smaller valves promote better torque. Stage I porting and a complementary set of cams on the new XB engine would be a VERY strong runner and a blast to ride in the twisties.

G'day Dogman


Just to back up what Crim has said

Nallins or Headquarters or Tilleys or a good local indy that ya can sit down and talk to.

The correct compression ratio is closesly linked to the cams you choose,the valve sizes and cams will mainly determine the VE (volumetric efficeincy) point or torque peak, which will give the motor it's character.

It's best to talk to whoever is gonna do the heads and go with their recomendations.

I have some customers that I put large cams and valves in and others that I keep smallish cams and stock valve sizes.
It depends on what the customer is using the bike for and his riding style.

I'm not gonna stuff Redshift 585's and a 2" inlet in a 1200 that gets riden 2 up on trips and never gets reved past 4500. :eek:

By the same token I wouldn't be using N2's and stock valves for an 88" drag motor.

Talk to a few shops and see what you feel is the best for you.

Ditto.
do the heads pick up 10 ponies..do the cams maybe 5 more...so the heads are the way to go...do you have the cycle shacks or some other slip ons?

A good 2 into 1 header should add some HP; I would perfer to move slower on a limited budget and get quality. And with the 2 to 1 header he still should have a few bucks for a cam.

I have had my heads done, got Cycle Shacks and a set of cams plus an ignition and got 84HP at 6300. I think 90's is a little high in expectation unless you want to rev a lot higher. I saw a 1200R with 883 heads and 9.5 wisecos with factory cams make 80+ ft lbs at around 3K up to around 4300. I was impressed. Of course its HP #'s were low with the factory cams but the Tq curve was very impressive. This is the dyno from yesturday.
The red curve is with N2's and the green curve is N3's.


Here it is. http://xlforum.net/forums/attachment.php?attachmentid=108

If you get a buyer for the se II ,sell them. The cycle shacks (aka se I) are way cheaper and make more power. I had the bike on the dyno all day with my indy . we ran the se II with no baffles , modified unstruction, cut out little holes, sortened baffle and no bafffle...it was a fun day. the cycle shacks made better results with the baffles in!
I had the hq mild heads at 10.5-1 and the andrews N8 and the cycle shacks and got 83 hp.

barry1967,

What kind of head work did you have done?

It started with a radial valve job with a little back cut I believe, shrink porting the exhaust side, a lump of aluminum welded into the intake side and then cnc'd to reshape it to increase velocity and I had the springs adjusted for height and lbs. Also took off a few thousand'ths to square em up. Thinner head gasket. Cylinders honed to round and squared as well. About 10 to 1 now.

It cost me 800 for all that but he gave me a bit of a break cause it was the first 04 1200 he did. Normally I think it was a 1000 job.

A 2-1 won't really add any HP over a set of old style slip ons. And don't discount the SE IIs. They aren't nearly as bad as people think. Just because they are quieter doesnt' mean they are down BIG on HP.

But if you have the baffles removed from you slip ons you've just killed a TON of low end power. I can guaranty that.

Could you guys reccomend a shop in Illinois?
