Lyle,
Who'd you order your bike through? Koups or West Shore Suzuki?
The place I usually run is on Rt 15 heading toward Gettysburg between the Camp Hill Mall and the Turnpike (past the Yamaha dealer). There at Rossmoine Drive there is the hellish bumps I was talking about so be careful.
I wringed the snot out of my old bike (750 Ninja) over on 83 between Yellow Freight (and the new Wendys) and Consolidated Freight. It's pretty straight, though it's super hilly. The night I did that run I had a big car gaining on me pretty quick and I was going about 95mph. I didn't stick around to find out if it was a cop or not. I tucked in and let 'er rip. I only encountered one other car before I got off the expressway. It was some little crap box Hundai or something. The drive must have been watching his mirrors because he actually moved over onto the median of the road to give me extra room. I'd have paid money to see me fly by him at those speeds (from his perspective).
Last time I did any high speed on I 81, I came down off of 114 to head South to Carlisle. When I his the seam between the on ramp and the expressway, under full power, the bike started head shaking violently. It was the first time that I'd ever had that happen. I rolled off of it slowly and it came back to normal. As soon as I was sure my underwear was clean I got back into it and it started head shaking again. The pavement must be rutted from all the semi-trucks.
I just remembered over on 15 I had my buddy's Vette up to 140 ('85 weakling) way out between Gettysburg and Heidlerburg. 15 is real nice out that way.
What's the track at Tower City supposed to be? Paved? How long is it? Circle or quarter mile? This is the first I've heard of it. Lotsa land up there. What a drive to get there though, about an hour.
