CB250RS Parts Transplant – A New Fuel Tap, A Name, Kick-Starting, And Packing Up Parts

Last week, my new fuel tap arrived!

While it fits perfectly, I didn’t fit the tank just yet, as I want to repaint it first.

I’ve also decided on a name for the resulting bike after the parts transplant.

As it contains parts from Eric and from Bruiser, I decided to smash the names together and came up with a few possibilities:

ERI-SER, BRU-RIC and ER-SER were all briefly considered before thought of ERIC-ER, as the bike’s working parts are more Eric than Bruiser.

This quickly became Erica, because the gender of inanimate objects is completely arbitrary anyway!

Heres a video of Erica’s first start after the surgery

After running Erica for a while, I decided to swap out the rear duck-tail fairing.

The original seat from Bruiser with the blue duck-tail fairing

Scarlet’s original duck-tail on Eric’s old seat.

I removed the very dodgy self-tapping wood screws I’d only ever intended to use temporarily on Eric’s seat

Bruiser’s old seat still had the original mounting screws, so off came the duck-tail.

Onto the better seat  and a close-up of the mounting screws.

A couple of vanity shots of Erica with the black tank still fitted until the blue one is repainted.

With the obligatory full shots of Erica out of the way, I stacked the spare mudguard and duck-tail fairing next to the very dented spare tank.

I decided the seat could go with them.

Looking at the frame, I decided there was still too much on it, so I set about stripping it down completely.

The ignition coil and High Tension lead were the first candidates.

The mounting posts shared with and the mounting plate for the Regulator/Rectifier were next.

The wiring loom and rear brake light switch followed soon after.

The gear shift lever and mounting pin came next.

At this point, I decided to start bagging things up and labelling them to prevent further damage and in case I decide to part them out.

I moved on to the wiring clips.

The kickstand seemed like the next logical step…

 

…until I realised I needed to take the mounting bracket for the footpeg off to remove it!

With suitable persuasion I was able to convince it, however!

I also removed the swingarm axle in the process, though.

Naturally, I removed the rear shocks and swingarm next.

.

I replaced the axle in the swingarm so I wouldn’t lose any of the parts.

I noticed the rear brake stay bar was attached with a split pin and bolt at the swingarm end as well, so I removed it and put the bolt back through for safekeeping.

The cylinder head mounting plate and cable clip were next.

The right footpeg and bracket came off fairly easily.

I’m glad I was able to remove the final mounting bolt by hand, as I don’t have an allen wrench this big! It was about 8 mm.

The horn and throttle cable guide came off the front of the frame.

By this stage, I had just the front forks and main stand left to remove.

As I don’t yet own a 30 mm spanner or socket, the main stand was next to come off.
The spring came off very easily without a wheel in the way.

The split pin was easy to remove with a pair of pliers.

The stand itself wasn’t quite so easily removed from the frame!

I got it eventually though.

With the stand removed, I picked up the remainder of the frame.

I found a suitable space for it and put the wheels away behind it

I cleaned up the main stand and its spring with some degreaser and they came up pretty well!

Finally, I started Erica and rode her up the ramp into the shed before stuffing the parts box full and locking up the shed.

The Parts Transplant Continues – CB250RS Motor Replacement

After removing the motors from Bruiser and Eric, it was finally time to install the working motor in Bruiser’s old frame.

First I collected the bricks from around Eric’s stand, as I would need them for raising Bruiser’s frame.

I also needed to pick up the mufflers! I hung the right header pipe up next to the left one.

20170304_141941 20170304_142248

There was room for the left muffler there too.

20170304_142319 20170304_142441

I’ve ordered a right muffler but it most likely won’t arrive until next week.

Next I had to remove the seat, rear fairing and rear mudguard.

I found a safe spot for them on top of the shelves.

Next was the tank, so I could see what I was doing.

20170304_142647 20170304_142802

I put it on top of Sylvie’s old rear wheel  (I should probably either sell that or get a new tyre and keep it as a spare!)

20170304_142843

With a bit more room to work around the frame, I scooted the motor into a better position and moved the bricks near the legs of the main stand.

20170304_143041 20170304_143122 20170304_143131

After lifting the frame up and putting the main stand onto the bricks, I moved them back a bit so the motorbike lift would fit in better.

20170304_143240 20170304_143306 20170304_143410

With the bike lift in place, I put the motor on it and raised the motor into the frame.20170304_143555

20170304_144405 20170304_144411

I gave the mounting bolts a good blast of WD40. Photos on the left are before, on the right is after.

20170304_144826 20170304_144934

It took a bit of effort but finally I was able to get all the mounting bolts back in.

I lowered the bike lift, took it out and removed the bricks from under the main stand.
A fair bit of oil came out considering none had come out when I drained the oil, so I mopped it up with an oily towel and put the oil tray back underneath.

I decided the sump plug should go back in next.

Next I reattached the gear shift lever.

Connected the High Tension lead from the ignition coil to the spark plug.

As there was no regulator/rectifier on the frame, I removed Eric’s

20170304_190543 20170304_190829

20170304_191102

I mounted the regulator/rectifier and gave all the electrical connectors a thorough spray with electrical contact cleaner.

I’ll need to move the lights, switch blocks, speedo and tacho to the other bike, so I started by taking off the headlight. from the front of the housing.

20170304_192833 20170304_192846

Since the headlight was working when Eric was run last, I took lots of photos of how everything was connected before unplugging everything.

20170304_193150  20170304_193250  20170304_193400

After removing the headlight housing, I disconnected the tacho and speedo cables and decided to call it a night.

20170304_193520  20170304_193544

Both Bruiser and Eric are now just half-bikes. I’ll need to stop thinking of them as separate bikes soon!

More on that next time!

She’s Missing That Certain Spark

Armed with a 5 Litre fuel can, I was all set to try starting Nix this evening.
She turned over fine but just wouldn’t start for some reason.

After double-checking the high tension leads to the ignition coils (my first time working on a twin so I’d forgotten there was another one) I found the second one also wasn’t connected.

After fixing that, I discovered that the plug caps didn’t seem to be gripping the plugs at all.
On further inspection, I found the reason – no spark plugs!
