95 inch flat top pistons,211 cams,older,first se heads,wild pig mufflers,se air cleaner,power commander,06 rk.made 78 hp,88 lbs torque,doesnt sound very good to me.im thinking the heads may not be suited for the cam orneed more cam for the heads to work.im afraid if i put more cam in it i will lose low end torque.any suggestions on what i should do would be appreciated.

If the tune is good I would look at a couple of things. Don't know who did the work but the cam timing may be 1 tooth off. I've seen that result inpoor numbers.Check your oil level and pull the pipe plug out of thebottom of the cases,right below the flywheels, see if it's sumping, you should only have a few ounces of oil left in the case.
Now this one is going to start some discussion. Check to see if the infector wires are on the correct cylinder. I kid you not tha local dealer did a stageIIbig bore for a guy here and the bikewas a complete dog; less than 60 hp. I checked everything, cams, sumping, intake, exhaust, replaced the ECM (with a spare) and to my disbelief the dealer had switched the injector plugs. I would have bet the bike wouldn't even have run but sure enough it ran, just very badly.

Now... regarding crossing the injector connectors.... onewould REALLY have to try hard to do that, as they are zip tied to length at their properlocation. ***BUT***.... I would not be surprised by anything from an incompetent installer.
did someone say..... tune?

yea... if you have a bad infector, you're S.O.L.

I didn't say switching the wires was easy but finding it sure as hell was; who wouldof thought? Maverick Motorsports of Cheyenne, Wyoming,the most worthless dealer I have ever seen, did it on a 2002 Road King last spring. You're right the zip ties and wire clusters should have been a clue. Call 'em and ask if its difficult 307-638-8307. Ask for the Service Manager who just over 2 years ago was the parts boy for the local cable company and has never turned a wrench on a Harley in his life.
The owner took it back in and complained about it. Maverick said the fuel tank liner was coming off and had the fuel filter plugged so they put on a new fuel tank. Same problem so they said they had no idea what the problem was and kicked him to the curb;I inherited the problem, but the man's happy now.

RE: big bore build horse power not good
i did a compression test today and had 165 front 168 back.the tune is right but from what i read i should have at least 180 psi or higher to run this cam.so,either i change to maybe a 204 cam or something in that range or get the compression up and keep the 211.leaning towards the 204 since it has more low end torque and wouldnt have to worry about spark knock and hard starts.what you think?

Which S/E heads are these?
I was ASSuming they were the S/E "Performance" heads, that when used on a 95" (properly setup), with flat-tops should be close to 10:1 or in the 195 +/- psi range for CCP. Cam timing influences ccp too, but this seems low to me.
165 is way off of that. We need to determine which heads these actually are.
"On the surface", it sounds like you may have heads w/ huge chambers and the result is low compression. I am now thinking the component selection could be suspect.

RE: big bore build horse power not good
ive decided to take the heads off over the holidays and recheck all the specs and see if thats the problem.i just about think thats where the problem is and im thinking about sending the stock heads off and have them ported to match the rest of the build.

RE: big bore build horse power not good
Hello all.Talking a new camfor the new year.
After looking at my available $ ,my dream of a 107 build was out of my reach
.However, the bug to acquire some more hp and torque and bigger
per mile had been haunting my dreams since late summer, soI decided to fix my problem- I mean it's Christmas soon right? Decided to go witha575-HS Red Shift cam from Zipper's Performance, http://www.zippersperformance.com/ca...&prod=2186
The exhast will be changed to a D&D Fatcat 2 into 1 from the current V&H BSS set up, and for it was decided togo wiltha Fueling oil pump and the Fueling lifters, withHD SE push rods.
Can't wait to see how this will run with Tmax download map for the above cam and exhaust; and perhaps a Zippers air filter kit too.
Cheers and Happy Holidays
