Last year, 2016, I had the engine in my 98 fxdl rebuilt by Hillside Cycle. Stage 2 heads, woods 8 cam, S&S roller lifters and rockers, HSR 42 with the round mikuni filter that clamps right on the carb with no adapter, and some other goodies. I didn't go big bore but the cylinders were cleaned up for the wiseco pistons, I think they are 10 or 10.5 to 1. I did the heat cycles and break in recommended by Hillside. I had a RBRacing prostock pipe on it for a while then switched to a D&D fatcat, sounded like I had a nascar stock car behind me with the RB pipe. The bike runs like a freight train and seemed to have endless power. At around 1200 miles I had it dyno tuned by a small independent shop here in Georgia. I ened up with 88 hp and 85 ft. lbs. of torque, I was thinking I would see numbers in the low to mid 90's on both. I thought the torque would be higher than the hp, that has me bit confused. My question is should I have it tuned again at another shop or are those some good numbers? I'm still in the learning process about tuning Harleys. What do you guys think? Thanks, and A Happy New Year to everybody.

 

You state "The bike runs like a freight train and seemed to have endless power".
Just ride and enjoy it, who cares about numbers?

EDIT: There is one member here That can't seem to find that missing 3 HP

 

If you take your bike to several dyno shops and get them to give you their numbers for it, none of them will be the same. That's the way with dynos, they are great tools, but not the most scientifically accurate. You say you're happy with your ride - be happy with those numbers!

 

Wise words

 

Those are good 80" street numbers, to get into the 90 range the compression would need bumped up some but brings some baggage with it. Going to cost a bunch more money and down time to get some more numbers and keep in mind that the dyno tuner may of played the AFR's safe without leaning it out for numbers. If he gave you a sheet, see what the AFR number is at the highest peak and report back to see if the tuner is playing it safe or if that is all she's got Captain Kirk.

 

Compares close to my 97 FXSTS, Which have basically the same Cam, Pistons and Head work.
Pulls strong and is very reliable. As everyone stated just enjoy it.

 

Those are good numbers, don't get worked up over a few hp or two. If it runs like a bat out of heel be happy with it. I'm sure you can out run most 88, 96 and even some 103 inch motors.

I have a similar build on my 1996 fxstc 80 inch evo. It has a 85 in big bore kit, 10:5:1 flat top wiseco pistons, head work by Hillside, 42 mikuni carb and D&D fatcat.

last but not least I'm at 92 hp and 91 tq I belive those are my correct numbers. Will be doing another dyno before the spring. The first dyno was before I broke it in.

 

Famous saying, too much is never enough.
Your numbers are in the ball park for a reliable 80" Evo.
If your out running all your buddy's 80", mission accomplished.
I did find that extra 3 Hp. It was hiding between the clutch and throttle.

 

I'm getting similar numbers out of my Kendal Johnson engine. Last year it developed a shudder after 65K miles and I had it completely torn down to the flywheel and rebuilt with basically the equivalent components. Probably could have kept driving it but I didn't want the engine to grenade on a road trip so I bit the bullet. They said all the parts showed normal wear and the rebuild should last a long time. Sounds like you'll can have a very dependable street engine that should last a long time. Only parts that failed for me was the stator (twice). You should be able to pull the front wheel up with it. Scared the crap out of me the first time I did it.

 

Thanks for the replies. If I'm looking at this readout right it appears the afr is right at 14. The test was run up to 6000 rpm. I always assumed that the torque would be higher than the hp just because of the nature of the engine, thats the part that had me confused. And as for lifting the front wheel, it does get light in the front end, dont think I want to try wheelies with 14 inch apes. When running up through the gears it dam near wants to blow me off the back, definitely a fun ride!!
