Busa guys and gals, I ride these rodes every week...Rodes are still in very good condition. Very little rock (seldom) on roads. I would recommend either meeting in Winters off of 505 and heading west up to Lake Berryessa on 128...drop dead gorgeous scenery...then you can drop on down to Lake Hennesy and Napa Valley...maybe an hour and a half at leisurely pace... or stay with the road that goes over to Spanish Flats on Lake Berryessa and then over to Pope Valley road and then to Napa valley (futher up valley)...If you really want some twisties get on up to Mt. St Helena on 29. Another fun route would be to meet up in Napa somewhere and go at it from that direction...go all the way up valley on Silverado, over Mt St Helena, through Clearlake, turns into hwy 20...spirited ride down to Winters...about an hour from Winters to Sac...Bay area riders would turn off on 505 and end up in Vacaville...My bike is torn apart right now for painting and mods...which is killing me to know the whole crowd I .org with and have never met will be out playing and I'll be sanding and spraying... Weather could be an issue and don't want to ride these roads once it is dark...My estimate from Napa to Williams is 30 minutes from Napa to Calistoga...30 minutes from Calistoga to Middletown..and 1 hour from Middletown to Williams...Williams to Sac 1 hr...Let me know if there is any routing I can help you with...I know every inch of these roads...2hip
