Hehehe. How did I know you were gonna say that Spikey?
It looks like you got a '79 there. Nice choice. We have 2 '80's. One done. One was going to get done but has turned into a parts bike for the present.
Be careful on carb kits. There a lot of places out there that will say 79-82 are the same, but they aren't. '79 and '80 are the same PD carbs, after that they are CV. Soos on here has experimented with different carbs cuz these are not user friendly as far as making adjustments. You may want to consult with him. Mlinder was going to do an experiment with us using a Suzuki GS550 set, I think it was, but we never got that far yet. The air/oil filters, oil bolt... are the same for a few years though and are common to other bikes of that time.
The charging systems
suck. Period. It is well documented through Kit's (and others) threads.
Go have a look. Hers is working well now but we ended up going to Oregon Motorcycle Parts (Tony Weeks) for a new reg/rect (charges at idle now) and had the rotor and stator rebuilt by a guy in AL. (Tim Parrott) Look up "hot start issue" to learn more on this crapper of a system. Clean every connection thoroughly and use dielectric grease. You're gonna need all you can get from it.
As for the bars... the fuse box is right there in the middle of all that. There are a few guys who have moved it and changed it over to blade fuses. That's another nice mod to do if you're gonna put clubmans on or something like that.
The bike is nice to ride and gets up and roars once it's tuned in right. The maint parts can be hard to find cuz, like I said, much of it was only good for 1 or 2 years.
There is a 650 registry here and I suggest you go introduce yourself and your bike there. The guys are good about getting back to you on questions re: this particular model, just make sure you put cb650 in the thread title.
Good luck and welcome to the forum!!
(Now tell Spikey to put down the 4 beers he's guzzling and help you with that bike.
