Come on Don, Tell us what your numbers are?
You did get the "Old Classic" Tuned today..
Mikey
Just got home. It was a beautiful day today. Sweatshirt weather on the bike until almost dusk. So I had to take the long way from the dyno shop.
The numbers aren't huge. But the motor wasn't touched up to be a huge motor. Torque is in strong and early though. That is what it was touched up for.
It responds to the throttle quickly and has good torque from 2500 completely through and beyond the pass-a-truck and cruising RPM range. I could care less about top numbers but some will want to know. So top numbers were 99.6 and 99.6. More importantly the curve layed out beautifully. Almost flat. One of the flattest torque curves a guy could hope for.
It feels very comfortable and is smooth going down the road. Not bad at all for a little 95" motor with just a pair of little 510 cams.
2500 3000 3500 4000 4500 5000 5500 6000
TQ 93 96 99 96 96 96 95 90
HP 49 56 63 72 82 92 99 96
Original stock first run for comparison
TQ 72 79 80 84 86 85 80 75
HP 38 42 49 60 68 76 82 81
In its prior trim the engine really caught its breath and started pulling its best about 3200. You could feel it take a breath and jump there. Now it's more torque at 2500 than it ever had stock; and it stays there. The bike simly never stops pulling. That's fun. Acceleration rate really does not diminish nor does it ever jump away from you. Simply solid from just below cruise RPM all the way to the top end.
Overall I'm very pleased with the reaction by the seat dyno. The bike feels great on the street or the highway. It's competent and comfortable in traffic and scoots around vehicles being passed on the two lanes without downshifting whether you're starting the pass at 65 or 85. It has become, to put it basically, a simple to ride very predictable engine with completely adequate highway pull from one gear below cruise all the way to the redline.
The combination was a simple one. Pair of little Mackie 510 cams, pair of stock late model heads off a 96" motor and a throttle body taken from 38 to 42mm by BC Gerolamy. I told Mackie I wanted a combination that came in early and pulled hard for awhile. Didn't care about anything else. That's exactly what I got. John Golden dialed it in beautifully. Worked with it for the best part of two hours before saying "we're there." It's now a very happy bike. Oh, and as usual for John the AFR line is even flatter than that torque curve described above.
