Anybody wondering what kind of h.p. numbers you can expect from Attic Rat's performance package, well here it is. These are uncorrected numbers and the dyno operator said corrected numbers would have been a bit higher because of the temp and humidity. My bike 98 standard. Mods: Attic Rat work, dyna ignition.
With Mark T exhaust w/crossover (stock headers): best run 114.58 h.p. and 108.36 Torque. Average of 3 runs 111.79 h.p.
With Viking exhaust: best run 121.18 h.p. and 111.73 Torque. Average of 3 runs 120.23 h.p.
The carbs are untouched since Attic Rat worked on it. Dyno guy said it could use a bit more needle to fatten up the carbs with the vikings.
I'll try to figure out how to post up my dyno sheet. I've commented many times how well this bike runs after Attic Rat worked on it. Now I know my "butt dyno" wasn't lyin! I always figured the guys bragging about the viking exhaust were partially full of it
......I don't think that anymore. It's too bad they went out of business.
