Mick,

I thought I'd be more aerodynamic as well, so I was disappointed to find that 80 was the top speed. I believe it's properly installed too, there's no wobble and my helmet isn't being rattled by wind. I did find a gain in gas mileage which is nice though.

I neglected to mention I was riding in a tucked position when I hit 90 mph.

This hill I did the 88 on is on my daily commute that I've been doing long before I got the bike.  As soon as I was comfortable doing 80 with it, it has become my performance gage.  When I got it, it was near stock and I've always done better than 80.

Ah, I think you;re remembering the Long Beach Freeway which serves the docks.  Big rigs three across all times of the day, pavement broken into jagged slabs by the pounding weight of overloaded trailers.  90% of the drivers illegal aliens -- talking non-human extraterrestials, not merely Mexicans; they think they are someplace where the laws of physics don't apply.  I don't use it.  To get to downtown LongBeach, the Aquarium of the Pacific, Parker's Lighthouse, etc. I take the Harbor freeway south then east accross terminal island -- much less traffic and joins up right at the southern terminus of the the LongBeach Fwy.

The Harbor Freeway terminates onto Gaffey in San Pedro, mainly carries commuters, especially south of the 405, so off hours it flys.  Which is amusing when you realize the CHPs base just off the Torrance exit.

That's why the freeways are safer, no sudden stops, just bounce along for a while before you start sliding.

What did the factory speedo indicate at the same time?

Downhill and with a tailwind, I guess that could be done.

You've adjusted gearing, but most people have to remember that ALL factory speedometers over-read by a few percent, rarely less than 5% and usually by 8-10%.  

So, when most riders see around 90 on the speedo with standard gearing/tires as top speed for their Savage, they're probably doing 82-4.  Call it 83mph.

So what do you need to get to 100mph?  Wind resistance/tractive force is proportional to the square of velicty, and power is tractive force times velocity, so power is proportional to the cube of speed.

So, to rise from 83mph to 100mph you're trying to go 20% faster.   If 32hp gets your Savage to 83mph, to get to 100mph you need 32 x 1.2 x 1.2 x 1.2 = 55hp.  A 70% increase in power.

Sorry guys, there's just no way on this earth that a standard Savage is going to hit 100mph whatever the gearing.  Unless, maybe, you find a 50mph tailwind, a 1 in 3 hill, or ride off a cliff.

As Scotty said, "Ye canna change the laws of physics, Cap'n"

That's no fair, you can pick up 10-15 mph easy when going down a long mountain 7 degree grade.

Just be prepared for your Savage to start using a little oil after one of them high speed mountain trips ....

Back in 68 I took my  62 Chevy Impala down the I 5 freeway 3 buddy's and I going to tijana for after hours drinking,they kept urging me faster and faster, I got her up to 105 mph, the bad side,that car was never the same,there were no knocks or any thing like that ,it seemed to have lost it's get up and go go,so maybe not a good idea tweaking a bike that just wasn't built for speed.
