those "keepers" on the alternator shaft are called woodruff keys. you can find them at some hardware stores like Ace. if your alternator happens to pop off the tapered shaft it can easily shear the key and possibly damage the keyway. its less likely to happen on that shaft because the starter motor is the only force applied on it other than the actual crankshaft. it's more likely to happen on stuff with a high rotational weight and driving force like a clutch or drive sprocket. be sure to always tighten things that connect via taper shaft to specified torque. I've had a flywheel that came loose and not only sheared the key but also destroyed the keyway, meaning a new crank was needed. bad day for sure! thanks again for making these videos, they'll be a huge help when I step up to do my cb350. it's also a huge inspiration, very motivational how you keep pushing on with the build even with the setbacks you encountered. and everything you did on this beaut was so detailed and overdone. so much work and effort applied to every aspect of the bike, down to the nuts and bolts. at the end of it all I bet you've become a cb350 expert! there certainly aren't as many hands-on type of people in this generation.
+Sir Charles Yes.. Woodruff keys! I remember that as soon as I read your comment. Thanks for the detailed explanation. I will most definitely torque everything down. I am keeping a list and marking the bolts that I've torqued so I don't miss anything. Everything will be thoroughly inspected by a licensed mechanic at the end of the build to make sure! Thanks again for the info man!
+Saturdays Wrench sure thing man. after all the time you've spent building this bike I'd hope that you could have thousands of trouble free miles to enjoy it! I'm not building my cb350 yet, but I'm working on an old vespa ciao moped right now. big bore kit yo, 65cc's! lol.
You will need to modify your steering stops if you are going to use clip-ons. Either drilling and adding bolts to the stock stops. Or grinding them off and making new ones/cognitomoto have a set of adjustable stops you can tap holes for.
+Overture Ya I was assuming I would need to modify those. I'm going to wait until I have everything together before I do anything. Thx for the heads up!
Saturdays Wrench Doing it now means less fiddling later, when you have to remove the lower triple you need to take apart everything >_> front wheel and all. You only need a drill press and taps or if you go for the adjustable a grinder/dremel.
+Matthew Corbett cheers bud! We're having a bit of a colder than normal spring up here at the moment so it's not making me feel so bad that the bike isn't ready haha
Another great episode Tony! You're really getting close to finished now. Re the preload drama, I take it that's only applicable with ractech springs? I have the same forks as yours but I'm planning on using the stock springs. Also, the fork oil measure technique you used. Is that a good guide even with stock springs?
+Anthony McFarlane Thanks man! Ya, so the techniques used to preload and measure oil are for those springs only. I should have mentioned that. I'll add an annotation actually. For the stock set up you'll definitely want to follow your workshop manual. I don't believe they require a preload spacer and the oil amount will definitely be different.
Great series! I am doing a cb450 curently and had some problem with removing the rear swingarm rubber bushings (ones that shock is bolted to). You never mentioned them and they look like they re painted. Did they survive powder coating?
+chajcu I definitely did not remove them and they survived just fine my man! Got new ones just incase but upon inspection they were fine IMO so I didn't sweat it.
I’m having the exact same problem with my CB350 Top triple clamp from Cognito. Wondering how much they had to take off to make it sit properly? Did they calculate the measurements for you or did you have to calculate them? Loving your videos!! They’re helping me through my build a lot. 🙂
just got my 72 cb350 twin. been watching your videos from the beginning. thank you and great job.
+Graig Cameron Thanks man! Good luck with your project.

Haha thanks for the positive vibes! Sounds like fun though. A little ripper! Good luck with it.

+Overture oh wow.. ok cool man. I'll look into it asap. cheers!
Lookin' good, Tony! That starter clutch footage was very useful. Hell, it all was! What's the temp up there?
+Matthew Corbett cheers bud! We're having a bit of a colder than normal spring up here at the moment so it's not making me feel so bad that the bike isn't ready haha

+Saturdays Wrench mine were all rusty and seized but eventually gave up with a loud snap noise you cherish so much ;) good luck on your project!
+chajcu thanks! You too.

+Trista Williams I sent him a picture and he sorted it out. It's weird that he wouldn't rectify the problem after I revealed the problem for him.
Where did you find the bushings? I'm currently looking for a set for my 69 but they are proving difficult to find.
+Chris Farrell send me an email and I will get you the contact saturdayswrench@gmail.com
