107ci All-Bore, TMan Stage III Heads, TR-625, FatCat BBQ, 51mm TB

[rodriguc]

Two charts are attached. One is the final results of my 107ci with TR-625 cams. The other chart is a comparison of the same engine with the TR-625 cams (tuned; upper curves) and the TW-8G+2 key (untuned; lower curves).

Below is the listing of components used on this build. Thoughts, comments or recommendations?

T-Man Stage III Heads (93cc/1.940" Int/1.615" Exh) and compression releases
S&S Roller Rockers
HD “B” Lifters and Camplate with Baisley/LMR oil pressure spring
Feuling Oil Pump

In my engine, the TR-625 and TW-8G cams made the same level of valve train noise -- low.

The clutch plates will be replaced shortly. Took the bike on a 20 mile run in single digit temps, but it took that long to get the engine to somewhat warm up. A longer ride will be necessary to truly assess the bike's performance.

Very nice. I'm really pleased with my T-Man parts, and Dave can tune them really well.

curves look almost identical, only 8 cam is a bit lower. so he tuned the 625, and the swapped in the 8? untuned? making sure i read that right.

Dennis, I think you got that backwards. I think he removed the 8 (untuned), installed the 625, and then tuned it.

Thanks -- you are correct.

Breaks a 100 torque very early in the power band and pulls well out the top, can't ask for more than that, what did Dave say about the little nipple in the graph lines?

huh????

OK, unusual spike in the torque and HP line then. Just look a little closer at the overall torque curve and tell me what you see. I bet Ahar would recognize it in a second.

Very, very nice rodriguc! Should be a lot of fun.

I'm looking to do a similar build on my Dyna.


That dyno spike has been seen here before.

Doc did a 107 tune last year that had a nipple like that.

Must be the cold weather!

You had 10.5 cr with 93cc heads? Wow......

I guess the extra cubic inches of the motor brings it up......must be tired, not looking at it right.....

He said it could have been the dyno machine spiking, though he admitted it was consistant in all the runs. I suspected the clutch, but was hoping to hear from others here on this abnormality before replacing the clutch. Thanks.

Thank you. Weather -- hmmm, never crossed my mind. I take it Doc didn't provide any explanation for spike?

Cubes, dome (10cc) pistons, and 0.040" head gasket
