That weird starter gear friction clip and a flooding question

I was too. I eventually got one off Ebay. It was a genuine NoS Yamaha one. But obviously it isn't getting any easier to find them. I can't say I trust 3rd party drag clips.

Generally Ok.
The clips would need to be heat treated as well.

So, further down the starter friction clip and starter cog trail. I ordered 2 NOS clips, and I have one of Mike's aftermarket cogs, which was slipping away in my friend Brian's bike, and I have one old OEM cog, pretty ground up out of my xs650. So it turns out that there are remarkable differences between the OEM and the aftermarket cogs. The OEM clips are too loose on both. I tightened the one for the original cog enough to get my 7 lb friction. The non-OEM cog, however, does not have a V-groove for the clip, but a rounded cove type channel, which is considerably deeper than the OEM V-groove, hence the diameter of the circle is smaller. To get an OEM clip to be tight enoughon the aftermarket cog seems to be next to impossible, without breaking it.You can hopefully see in the pics the differences, the ground up cog has the v groove, and the larger diameter, as is seen by the gap left by the end. Both have the same NOS clip from Yamaha. No wonder the clip is sloppy on the aftermarket cog....1.pic shows how the clip ends are not even close to the same distance, 2.pic shows the channel difference

I recently installed a new gear from Mike's and made the same observation about the clip groove.
The difference in the groove can be clearly seen between the new vs the the old gear.
My gear is the stock gear from my late '75 build XS650C.
A question I had was do all the OEM gears have a "V" shaped groove or did Yamaha change them at some point and that's what Mike's gear is patterned on?
As you note, it could be surmised that the "U" shaped groove could provide more surface area for the clip to engage.
I used a NOS OEM clip with the Mike's gear. I checked the drag and it was in spec without having to alter the clip. (Which honestly kind of surprised me.)
It's working fine in my bike at the moment. How long it will last remains to be seen. I tend to kick it when it's cold and only use the starter after it's been running and it's hot.

With the V-shaped groove you get two 'lines of contact" vs one with the U-shaped groove. And they are also on a slightly larger radius.
Another very useful and interesting observation from a forum member!

@ JĂĽrgen ore who knows: where you get this 7lbs from ? Is this the moment when the clip start moving in the nut? I measure this with ~3,5kg ...?
Did anyone here measure the Amps while starting ore the Rev of the Crankschaft while Starting?
I have here "my tuneUpStarter" installed in a 750cm3 and the Crank get 260 RpM at apprx 180 Amps - falling to apprx 90amps. Current apprx 11Volt
The "Old Fashion Starter" need 230 Amps and fall to 160Amps ... the current whas less the 9Volt.
My 650 crank with "my TuneUpStarter" 340Rpm and even 11Volt, 140 Amps falling to apprx80Amps.

I think NOS OEM drag clips are getting harder to find. I got one last year in the UK off eBay. Don't think I have seen one since.

Hi XS Fellows ... maybe i have some intressting news:
i also bend or squeeze the Cliptail together to reach more tensions/friction. But with my concerns about "to break the molekule to much" and get some microcracks i do it around a 4,4mm shaft of an broken M4 Tap. I use a 3jaw chuck of the Lathe, (ok , this time the where some "markings" in the steel, next time i take some Cupper between the Jaws!) but more important for ALL of US : that the force grow from 3,5 to 4,5kg - so youres will get up from 7 to ~ 9lbs... i hope you'll try that too and wrote and answer of youre results.

I got Brian's Bike to work with an OEM clip and an OEM cog with no bending.
Still looking, not seen one. I want an OEM drag clip to keep for the day I need it. Which will surely come

I measure the "mikes" clip, these set with the "U-Groove" with only 2kg/4lbs, -Still looking, not seen one. I want an OEM drag clip to keep for the day I need it. Which will surely come
I am not convinced by the aftermarket drag clips. I have a new old stock one in there that I fitted last year. The day will come when I need another one.

Ore you learn to bend him like i show it...
I had to look and found these.
Well I ordered it and got an email from the seller telling me the listing was incorrect and it was $10 for one, not 5 so asked did I still want it. For $10 absolutely even if it is only one.
