Port Orchard, nice town. So you know about the rain. We have had about three dry days this spring although we are having a couple of days of nice weather but it supposed to be back to 60 degrees and some rain by the weekend.
Anyway, if the rake and trail works out good it's probably OK, a lot of trikes end up with some front wheel wobble, even the add kits for bikes where they have to put on raked trees to get it out. Mine turned out pretty good, a slight, low speed wobble but I put on a VW steering damper and it's gone, handles very good actually. I messed with air pressure in the forks, put air shocks on the back, tried different air pressures in the tires and it kept getting better. I can let go of the handlebars and tracks great.
