Recently bought a CB750F in Columbia SC... PO said it wouldn't keep a charge, appeared mostly intact and only about 30k miles.
Took home, and after spending about $30 bucks on a new battery and a few hours tracing wiring, found Volt Reg wired backwards, some wires unplugged in headlight nacelle. put back together, hit the starter, and in about 1 rotation started up! (but shot to maybe 3000rpm before I killed it!)
put on maybe 100miles, battery going down, so started a little basic maintenance. Thats when I went to check points, found a Dyna III ignition w/ stock coils: then went to clean air filter, found a K&N... someones been working on this baby a while back!! could be good or bad. am reading and learning about electrics and coils right now, great forum. looking at alternator now: is there supposed to be oil in the alternator chamber on the SOHC? I'm getting mixed answers from people locally... I have some, not a lot, but some in the alternator side cover.
I also ride dirt bikes with my college age son and friends (84 XL3550R), plus have an old CB 350G thats been in family since new that I'll restore after I get the 750 running reliably!
Like a lot of us, started riding in jr high on honda 50, went to SL125 & 305 dream, then MR250 Elsinore (wish I still had that one!), then Kaw KDX250(wish I still had that one, too...), then stopped riding for maybe 10years, then a Kaw 1500 Vulcan Classic (wish I kept that one too), now the XL 350R, CB350G, and son's Yam XT200. Worked on fixing up every one except the KDX 250, when I was more interested in my soon to be wife... I kept that one.
I'll be searching this Forum a lot, I like Hondas & CB750s, great bikes... I'll also be looking for HondaMan's advice on the proper coils to go with the DynaIII, plus maybe his resistor pak.
Good to meet you all, mike in SC
