My RC24 resurrection

Yesterday was another cleaning and inspection day. Removing decades worth of road crud from under the wheel arch and all over the swingarm and suspension pivot points.

Before



After


Removing the old chain with the world’s smallest junior hacksaw.


Rear sprocket looks ok. Teeth don’t seem too warm. Rear disc, not so much! New one on order.


Wet and dry paper over the cans to get rid of the surface corrosion.

Can’t even get the pad pins out, let alone move the pistons. This bike…..

Tantrum averted! Pins are out with a bit of persuasion.

needs to be cleaned and lubed for rear brake to work right



be careful not to destroy the 2 rubber boots.

 

Thanks @squirrelman. I’ve seen that on the B5dreams website. Currently soaking in penetrating oil to try to get out, in a day or two.

The two rubber boots look shot, so will have to replace anyway.

A quick update, although to be honest, not much to report.
Firstly, the fuel pump. After trying to source a quantum one that they recommended, I gave up. I just couldn’t find one available anywhere. Then I was idly browsing eBay, when I saw a German company were selling a genuine Mitsubishi pump, that was compatible. Fabulous! So dropped a stupid amount of cash on it and it arrived last week. All great, except it’s got a female connector on the electrical connection instead of the original male. So I now need to source one and get it soldered on. Not a biggie, but just another thing to source. I bought the pump knowing it wasn’t an exact match, as it has straight inlet and outlet tubes, but it seemed buying a genuine Mitsubishi item was better than not. Hopefully, I’ll have it fully connected up very soon.

secondly, the rear brake caliper. I was religiously soaking the pistons and then I went out and bought myself an air compressor to try to push them out. No dice, they are stuck fast. So I’m biting the bullet and getting it refurbished by a specialist company. If the pistons need replacing, which I’m pretty certain they will do, then it’s going to cost me around £100. It’s the brakes so I don’t want to compromise and it will save me a ton of hassle. I’ll be sending it off next week.
Thirdly, the rear wheel. I took it into work where I have a bit more space, to start cleaning it up, but the grime and gunk is coated on very thick. Then had the brainwave of getting a jet wash onto it, which should do the trick, only for a hosepipe ban to come into force yesterday. Doh!
In the meantime, I’ve got the brake torque arm and chain guard to clean up and I might a well start stripping off the front brake calipers, ready to get them sorted in a couple of months.

 

Before you commit to sending the caliper off, check this https://www.ebay.co.uk/itm/32440678...xLeBmr82sGbzZjWoMDx8G2dOM=|tkp:Bk9SR9Lt157bYA

 

@Thumbs. That’s a great spot. Thank you!

I have a chunk of tube with an old Honda Shadow master cylinder mounted to it with a short brake line that I cap and keep bled. For the calipers that won't finish off with compressed air, I mount the tube in my vise and pump the pistons out. I will usually try and pump them most of the way out while it's still on the bike (that's if the system is even working!), and finish with compressed air somewhere outside and away from everything that brake fluid likes to destroy. Some people will use a grease gun to pump the pistons out too.

 

Correct Cap … sometimes that piston comes out with a vengeance with compressed air ….

just consider all the good used calipers cheap on ebay or waiting in salvage yards, alot easier than dealing with frozen brake pistons, with prices often in the $30 range.

Ok gang. A bit more advice needed. As you can see from the picture, I have a shiny new Mitsubishi fuel pump, but it has the same connector as on the other side. I’ve been looking up electrical connectors. Am I right in thinking this is a two way connector, before I put my order in?

Also thanks to thumbs. Had to wait until payday but I managed to buy the cleaned caliper he spotted. So hopefully will have a bit more progress made on the rear end.

or you could just clip the plug and easily connect the wires to the pump. so you need a male for your female ? you can always fix it later.

(quick and cheap battlefield medicine)

 

Thanks Squirrelman. I thought I could hard wire it some how. Might do that to test and get it up and running.

I would recommend Cycle Terminal - cycleterminal.com. Frank's service and selection is excellent. Might be cost prohibitive due to your location.

Eastern Beaver is also a great source for connectors.

 

Norcal.... great site!!!! Thank You!

 

I’ve had a few busy weeks at work and no weekend time to work on the bike, so nothing really done until today. I managed to find a UK motorcycle electrical spares shop www.bikerstoolbox.co.uk who sell the appropriate electrical connectors. So today I got around to putting a male connector onto the Mitsubishi pump I sourced. 20 minutes of soldering the connectors on and some gentle coaxing to get them into the connector body. Think I made a pretty decent job. I’ve always enjoyed soldering. The Gods were on my side, as the colours of the wires on the pump were the same as the other connector, so I could assume that I was soldering them the correct way round.



So the moment of truth. I haven’t connected the pipe work back up fully, as I was expecting something to go wrong. But no!!! A working pump! Put my finger briefly over the inlet and could feel the suction and no blown fuses. I’m a very happy boy!

I’ll try to get it all plumbed back in tomorrow and prime the pump before firing it up.

Assuming all goes well, the next stage is to buy some pistons for the refurbished rear caliper and get that all back on board. Then it’s rear wheel respray time. Onwards.

yay progress!!

 

I’m a very happy bunny! Primed the fuel pump and lines using the jumper wire on the terminals of the pump relay and it worked like a charm. All four cylinders firing nicely and it’s starting on the button with a 1000rpm idle. Much smoother than before and not as clanky. Still needs a carb balance but I think I might let the garage do that when I finally take it in for its MoT.

I know I still have a really long way to go and this bike’s going to throw up a lot more surprises, but this fuel pump issue has been vexing me for ages. Actually feel like I’m going to get it finished!
