I don't know why, I am a paid up member....it keeps asking me to sign in... 
I was never posted to SJAFB, SC. I visited there once and some body in the Exchange walked up to me like he knew me and said "Hi! how ya been?" I just went along... I have no idea who it was....  
I worked on JC-130, MC and AC 130s, then cross trained into Veh. Maint. 
I was posted at the following in turn: Hickam AFB, HI., Hurlburt Fld. FL. Eglin AFB. FL., AFI Iceland, Homestead AFB. FL., Eielson AFB. AK., Goodfellow AFB. TX., 
McChord AFB. WA. I retired there. I now live across the sound from McChord near Bremerton, WA. 
I found the wires for the circuits missing in my fuse block, apparently there fuse terminals were lost and they went to an in-line fix.... ok....  
Are the all the plastic parts on the VR ABS? Has that been confirmed? 
I got the seat off, what's under there is kind of intimidating...I have a Yamaha manual but I also know the manual doesn't tell you all you need to know... 
Thanks for your kind response! I'll be checking back....feel free to email....
