Just to be clear, this is only an issue if using the starter, correct? Kick start it is just fine?

If I’m understanding the operation correctly then yes. When you use the starter it forces the clutch to engage allowing it to “kick” over. The kick spindle doesn’t engage this clutch to “kick” the motor.

Yep, kick away

That starter clutch replacement without splitting cases is apparently not too hard if the primary chain is not replaced recently, giving you a bit more play.
But splitting the cases can allow you to inspect and clean or replace stuff you would not have been able to do without splitting the cases.

took me a few weeks to find time to read this thread. dayum... I thought I was being ambitious with my first build. great job! my chest hurts even thinking about having to take the case apart.

Been a bit busy last 2 weeks with work. Haven't been able to get out to the bike and the garage is heating up from the weather. I've ordered the parts to rebuild the starter clutch and am just waiting for them now.

I did get a prototype delivered today for a rear brake master cover. The master was a little exposed for my like and had some sharp parts. My leg and these parts didn't get along when I kicked to motor over.

As far as the first attempt I am pretty happy with this guy. Need to thicken the base slightly and recess the bolt head opening a little (bolts pictured are too long). Then I'm just thinking through the overall look and shape to see if I want to modify anything. Only thing after that is to decide on a final material. Thinking about 3d printing the final part in stainless or a rigid plastic. I think it be cool to have at least one part that is printed.

Could turn some button washers that served to seat the bolt heads as well as shield them with a bump or dome if you wanted to recess the bolt head

The material is thick enough, I would countersink the holes and use flat head allen key bolts to secure it.

tshrey · « **Reply #582 on:** May 31, 2018, 10:51:10 am »

And paint it the color of your tank, that would look sick.

I need to add 4-5mm on the back so it clears the master. The heads already sink in but stick out like 3mil. Easy fix on both parts. I have it pulled out in the pics so there is a gap on the back you can't see. And those bolts are like 25mm, I need 12mm ones to fit correctly. Just what I had lying around to mock it up.

Ooohhhh. I really like that idea.... I'm gonna have to really think about that.

bambuhiphop · « **Reply #585 on:** June 10, 2018, 01:08:51 am »

Still waiting for parts but I went ahead a removed the starter clutch from the motor. Pretty easy task actually. Getting the oil pan and exhaust off took more time, ha!

But, I think I located the problem. I have a pin missing!!! Should be an easy fix once the parts get in. Pretty sure this fell out before I reassembled but I am going to scope the motor to be sure. I can't think of a way that his could fall out in the motor.

RAFster122s · « **Reply #586 on:** June 10, 2018, 11:12:33 am »

It has a roller, pin and spring...are all 3 there? If you disassemble that by removing the screws then they need replaced with new screws and use thread locker...a must! There is no need to disassemble it.

I would hope this isn't a PO's sin as it affects the starter working properly...surely they would realize this before reassembly.

MoMo · « **Reply #587 on:** June 10, 2018, 02:39:35 pm »

you are right in that the roller could not have fallen into the motor if it was in when placed onto the gear

RAFster122s · « **Reply #588 on:** June 10, 2018, 02:47:57 pm »

Likely dropped out when putting it back together and they were not observant. If it fell out in their shop I wonder if they would recognize it for what it is or think it was an odd thing. Another reason the bike was sold. Hope you got a deal on it.

MoMo is correct about it being unable to escape when assembled.
As if there was any doubt...

The previous owner did no engine work on the bike. It had been sitting in a field for 14 years under a tarp. I picked it up for $200.

The fault lies with me on this. I missed this piece on reassembly being a first motor rebuild and all. I took the motor down 2 years ago so I don't recall the pin falling out but it obviously did. I'll rebuild the whole component just for good measure. It was literally the only component in the engine that wasn't rebuilt.

Ok then... Motor seems to be better. I was able to get everything back together. Clutch took about 30 minutes to work back in. Just as an FYI for anyone my primary chain is brand new. So, this repair can be done with new chains. Got some oil in the bike and the electrics all hooked back up. I need a new battery but bike starts strong now. Ran for 10 minutes.

Have a couple issues to still work through. I'm not getting a rpm readout on my gauge and have a small oil leak by my filter. Now I'm running through some checks to make sure I've got good oil flow to the top end. Going to pull plugs and check them out.

Here is a video of it starting and running. Youtube embed doesn't seem to be working so here is the link. Would love feedback on how this sounds....

I also got my brake strap made. Thanks to luvmy71 to strap turned out great. I made some changes to my design. I got it painted up and mounted. Brake line runs into and along the back so it is nice and out of the way. I think it turned out great and have great clearance for the disc and and rear tire.

Hey, just came across this post. Also bought the C5 Ignition for my 550F and was curious if you’d be willing to sell me coil mounts?

So I have 2d drawings of them at the moment. I can easily share those. PM me your email and I'll send them over.

Bike looks and sounds amazing. It has a nice growl to it. Will have to go back through now and read the entire thread.

I have a stock ‘75 CB550 that I have running and would like to get out on the road. Last thing I need is a straight clean set of handlebars.

Thanks for the response and offer. Seems you have PM off. Mind sending me one?

Any updates on this project? I was following this one pretty closely before.

Thanks

Unfortunately, not really. I had some additional parts 3d printed for my tail light and seat mounting. Got those completed and then the permits on our remodel cleared so I shifted to that pretty hard. Garage is full of lumbar at the moment.

I need to finish the seat design (and make it) and then re-coat the inside of the tank. Aside from that the bike is about done.

Godffery · « **Reply #599 on:** January 23, 2024, 10:49:16 am »

So... It's been nearly 6 years. You ever get that lumbar out of your Garage?
