Split pin or R clip ?
« on: July 18, 2023, 12:07:06 AM »
I know this will have the restorers getting annoyed because it's not original but in my opinion ( which it must be said isn't worth much ), it's R clips everytime, everywhere.
While pulling my carbs apart to replace the smashed one I had to remove the choke rods which entailed getting the stupidly small split pin out from in front of the washer. I looked around for replacement ones and they can probably be got but I found better
As I said above I use R clips wherever I can as split pins are awkward, single use and arse ugly. I found clips that go through that tiny 1mm hole at an RC car shop. They are used to hold the body shells on RC racecars.
A far more elegant and simple solution and should I have to pull them apart again, quicker and reusable
Also they are stainless so no manky rust, the washers they hold on will also be replaced with stainless
i blame Terry

Also they are about $5 for a pack of 10 or on eBay $18 for 100 in 6 assorted anodised colours

And while I'm talking about chokes, when the carbs were apart I noticed one of the little flaps was not retracting into its housing when the other 3 did, so unbolt it's activating rod, pull it out, drop the choke door/flap out of the carb body and into the bag of spares for Terry.
I know it will be fine with chokes on only 3 carbs, years ago when I was on the freeway the throttle jammed wide open, further inspection showed that one of the flaps had snapped and dropped into the throat jamming the slide fully open, wiggled it out and never bothered fixing it. Made no difference to starting

Choke rod lenght can be adjusted.  All have a threaded socket.

Hook it off rotate to make it shorter if not lifting completely.
I used cheap cotter pins.

I prefer the R clips(hitch pin clips) or as we referred to them in the parts room in the 70s, fistaris clips.
I kept a dozen hanging on a peg behind the counter to offer customers that came in looking for a cotter pin for their rear axle. Once they learned of them they'd by a couple more to have on hand in case they lost the one.

I use “R” clips whenever possible. Years ago, I bought a huge assortment box on line for $9.99, that should last a lifetime. My son did manage to lose one from the back axle of his CR250 so on the dirt bikes I ensure they go in from the front, open leg on top.

For stuff that gets serviced infrequently I prefer split pins, especially for hard to get at areas where I want firm security. They require a bit of skill to bend nicely and if you don't bury the heads they come out easily. With a vibrating bucket of bolts like a Kawasaki Triple; split pins, loctite and loc-wire serve very well.  I do use the re-usable cotter type on rear axles for chain adjustment ease. Split pins come in plain, SS and cad-plated versions.
