rbengineering Started a new thread CR125 Clutch waterpump cover
8/22/2021 5:13am Hi all, I run a small cnc engineering company in my spare time and it's pretty much bespoke motorcyle parts I make.
I have received a request from a customer to manufacture some billet aluminium clutch and waterpump covers for a 1985 CR125 to replace the heavily corroded magnesium ones he has, and was directed by the owner to this...

1/27/2014 11:45pm Nice manners, don't suffer with that sort of behaviour here so it's a shame you don't get your facts right either. It isn't a 5 minute job I work 2 full time jobs just to pay the bills so I REALLY DO NOT HAVE A LOT OF TIME ON MY HANDS. It's been sat on my machine for all this...

1/26/2014 1:51am Hi Guys been a long time, and I have done more on these, however it's not something I get much time to do and I found a brand new Honda cover at my local shop so my original customer bought that, I could not believe they had one and they only found it clearing out old stock. I will see...

7/7/2013 2:13pm HI guys, ok I hope to show some updates again soon, I need to reply though as I appreciate it's taking a long time and I get many emails on this project. Unfortunately this is not so much because of any other reason than that my business is very very busy and I am the only person doing the work...

5/23/2013 1:40am Hi Guys, no I have not gone into hiding! I am very sorry but I am a one man business and I have my core business to run and bills to pay as well as doing these "projects". Unfortunately (for this project) I have been overwhelmed with race engine builds so it has not enabled me to progress this project...

2/28/2013 8:33am Hi Rob, I believe Farleigh Castle is not too far away from where I live so if they are all proven out to be right then I see no problem in taking one along.

2/23/2013 4:47pm I was machining the prototype today and got a fair bit done, I intend to do some more work on it tomorrow, I will post up some part machined photo's also.
Will still be a whlie as there is so much work in them, but it is very much still on, just can't rush it!
Kind regards Rich

1/30/2013 7:38am Dave cool, you certainly got a lot more bikes in the US than here in the UK, you are gonna be busy if it takes off.
Here is the latest cad model of the billet cover with the clutch inspection cover also fitted to it.

1/29/2013 1:31am Newmann, there is a guy in the uk who has the 1983 covers cast in aluminium already so probably not worth doing thouse for me.
Those levers could be done but again it's how much demand, and could you tell me how much people would pay as they have to be affordable.
Good luck Dave.bonz.9!

1/28/2013 8:20am Hi Rob, the prototypes are almost ready for machining, kidkawie means that where the clutch inspection cover joins the one in the cad model above that he suggests using an O ring as a seal between them. We will be, so don't worry.
I will post up some more progress hopefully very soon!

1/15/2013 12:31am Thanks guys, I need to make sure the part comes out right and useable and do not want to get too many people involved as yet, I have decided to go ahead with the '84 & '85 125's as I have definate buyers on those.
Another guy on a uk forum who was selling them at silly money has dropped...

1/14/2013 6:44am Dts717, how serious is your your interest? So far I have interest in 2 x '85 CR125, 1 x '84 CR125 cover and 2 x '84 CR250 covers.
If you would definately like one if they can be made, that would be enough to swing the first run in favour of the '85 125.
Let me know, kind regards Rich...

1/10/2013 10:37am Thats's fine jt, I will take some dimensions from the '85 ignition cover. Are you looking for an exact replica as you would need a casting, or a billet cover of your own design?

1/10/2013 4:52am Hi, thankyou, that cover does look like the 1985 one from the photo I was sent, I will pick it up on the weekend and take a better look.
As for the ignition covers, I am always interested in making parts that are rare as it's great to keep the bikes going, can they be made from billet also or...
