Handling quirks

[old77zrider]

Gentlemen,
My buddy just bought a 2004 r1150r. The bike is in pristine condition with about 7k miles. He believes the bike is fine. I rode it and was a little unnerved when I shifted gears under a fair amount of power. I know that shaft drive bikes usually exhibit a bit of a rise and lowering of the rear when the power is applied and backed off but it seemed to me that it also exhibited a bit of a twist. I'm just afraid that we might be ignoring a safety issue here. Any suggestions or comments to offer? Thanks for your input.

Also, how much should I pay for a 1994 K75 in great condition, with only 7k miles, a windshield and BMW hard saddlebags?

Thanks again.

if you allow the engine to spin hard, with the clutch disengaged, then yes there might be a bit of a "twist" - in normal operation the crankshaft and output shafts turn in opposite directions - effectively negating each other's torque effect.

If you were changing down a lot (ie two or 3 gears, thus necessitating a blib of throttle to match engine/gearbox speeds) then yes it can happen. It's no biggy though the bike is heavy enough to damp out most of the torque effect anyway and it won't upset the handling.

On the K75, anything under $4K is a great buy.....owned one and it was great bike. Had to work the shifts but it was smooth and solid.

Riceburner,
Please let me clarify the riding scenario a little more clearly. I was not beating the snot out of the bike or drag racing. Although I was pretty firm with the throttle I shifted at about 5000 - 6000 rpm and although my clutching may have been a little slower and more deliberate I was not spinning up the rpm and then dropping the clutch. I did back off on the throttle between shifts. It was (in my opinion) a spirited pace at best. Slightly more aggressive than one would be when merging onto a major highway.

If this is not normal, what might be the problem?....anyone? I'm open to suggestions.
Thanks


Also, what bike(s) do you ride? After a 25 year layoff I bought an 03 FZ1 and love it.
