Thank y'all for your responses. Yes, T-Mar there is a Made in Japan sticker. The 600 components are RD-6208 and FD-6207. The crankset and shifters are 6207 and i'm pretty sure the brake levers are 6207 as well.
If this is a mid range roadie, does that mean i can have a brook saddle on this baby!, I would really like to get this to roadworthy condition. I like to keep the 600 components because they shift like butter. I expect i would need new cables, wheels/tires new freewheel cassette. brakes. and maybe new chainrings and of course a new chain. I was going to bring it to my local bike shop, when i bought in my Rans v2 formula for a major tune up, to see how much they would charge to get the shogun 1000 back on the road.
Only problem with the shogun is the bike is a 58cm with 32 inch stand over height and i'm 5'8 with 31-32 inseam. But it rides so good. even with the wheels being untrue.
