Mine starts meandering around in the long sweepers sometimes. So far it hasn't tossed me in the weeds.

Moto,

Are your tires properly inflated?

It's Time for the Metzler to go on the front.
The 05 had no windshield or bags and there is a LHsweeper that the speed through was limited by the handlebar oscillation. I don't NEED to find out if it was gonna become unrideable if I went faster.
This one is an 02, windshield, possibly not To The Millimeter perfectly centered and aligned, but daggum close, and bags in the wind. I should hit the sweeper that gave me grief on the other bike and compare.. I've Been on the road, I just don't remember if I hit it climbing toward sixty.  I should check before the tire swap.

Tire pressure is good, I think I set it around 30 psi.  Happens on both grooved and smooth pavement.  Nothing mounted on front.  All bearings are sound.  Tire looks good (probably 2k miles on it), but maybe it's out of balance.  Obviously I'll have to check it out.

Like I said I don't think I even had the bike on the freeway last season, but there are a few areas I would sustain highway speeds for a few minutes.  I don't recall any wobble, but maybe it would have been there.  

I did raise the seat a few inches from last season, but it went straight up.  If I had the guess, I'd say my new seating position would have moved the weight slightly forward.  But I think the front end has the sensation of being light.  Can't quite put my finger on it yet.  One big difference between my bike and most other Ryca style projects is my shorter stock shocks.  Maybe the shorter forks need the longer shocks to...I don't know...plant it?  If that's the case, the the stock forks should really suck.  Not adding up.  Hell, maybe I'm like a big parachute on the bike and I'm pulling the front up!  I just can't put my finger on it.

I have a buyer for the forks that I've been running since I lowered it.  Maybe I'll leave the original forks at their stock length and see if that has any affect on the situation.  

Mostly I was curious if anyone has had similar experience with lowered forks or DS tires.

Did you use spacers to lower forks? If so, there isn't a lot of compliance to that set-up. Not only does it make for an uncomfortable ride; it also allows the front tire to micro-bounce because the suspension can't move quick enough to properly react to the road surface. While this can go unnoticed at low speeds, I would think that it would be quite pronounced about 60mph. Having the shorter shocks does move the weight distribution more towards the back of the bike, making for light steering.

Yeah, I raced motocross for years.  This is no tank slapper, been there done that, thankfully, always on dirt.  

Just a little shimmy.  Mainly looking for feedback from the guys who have run Ryca style builds to confirm that this isn't the norm before loosing much sleep over it.  

The reduced trail is on the list of suspects, that's why I'm asking the question.  If you think about a Ryca build, they reduce the trail and increase the rake where as I just reduced the trail.  Arguably, my bike should be more stable than a Ryca style build.  

I might take the Freeway home today and sit on tank. LOL 

It is tricky, because reduced trail can cause a light front end as well as the wobble.  I'm a pretty big guy at 6'3" and 250 lbs.  So I am probably decreasing the rake and trail even more.  On the other hand, most Ryca builds are using shocks 2-3" longer than mine.  Hard to believe I'm running less rake and trail than a Ryca.  Then you add tires and the quality of suspension to the equation like Gary pointed out...it could be anything!
