1990 CBR1000FL...Sat for 14 years, alone....

[Hairsy]

I cleaned pilot jets on a CBR600. I blew carb cleaner and air through them, prodding all the holes with a nylon bristle from a washing up brush. Lots of soaking and repeating. One needed a careful prod with a brass thread from a grinding wheel.

 

You can check them visually as you go to see whether they're truly unblocked.

 

It takes time and patience but I'd definitely do it again rather than buy new. Just be careful not to get too aggressive and enlarge the holes.

Thanks Hairsy. That was my original thinking. clean them up and lob them back in, replacing the flat o rings as they're not much cop anymore. They were nowhere near as bad as your CBR ones (I'm using your thread as inspiration ) and other than a bit of gunge they're probably ok. My only (minor) concern is that they've done 44,000 miles and having never seen if/how they wear was a bit unsure.

So. The saga continues ... although it may be necessary to join SAGA by the time I get it done ...

 

Today's foray consisted of cleaning carb #2 and seeing if I could get the clutch to do something. 

 

Carb 2 seems to have heard that someone wanted to clean it and thought it'd give them something to clean. It wasn't too grim but jets were definitely gummed up with joy.

 

YouTube is great isn't it? Learned all about how ultrasonic cleaning works and how these people that rebuild bike have really deep pockets/shallow morals and can just buy stuff

 

 

 

Expensive month this one so bits are on the shopping list, awaiting payday as food and mortgage takes precedent..... Definitely need o rings and seals for the carbs, jets look ok other than the gummy mess. 

 

Put 2 litres of white vinegar in the water system as I think the water left and the glycol didn't. I put in some water last week to see if it leaked but when it came out this morning it was a bit grim and has coolant residue in it. 

But of white vinegar always helps shift the crap. (Maybe ...)

 

Clutch fluid put in the master cylinder and pumped, bled it through until it came out clear. It really wasn't to begin with!

unsure if the clutch is actually functioning. I'll leave it for a bit as I don't want to take on too many things at once. Seems very "loose"

You can't ride a house nor a plate of food 

[Egon247]

I thought I'd have a poke around on the clutch and see what's what today.

The slave cylinder was well and truly stuck in position with, what I can only describe as a hydraulicy oily goop.

 

This led to much pumping and squeezing and squirting.

Which sounds like a great night time activity but not where clutches are concerned. 

 

Eventually it shifted and popped out. I'll change the seals anyway but I wanted to see if I could get it going. 

My eldest came down to the garage as he's showing a bit of interest in things other than the Xbox so we went through how hydraulics work and why.

Which was nice. 

After learning why air is bad, we bled it out and it actually functions! Woo!  Working clutch!!!

Yay. 

 

[Simon Davey]

Woohoo, you'll soon be blurring those white lines

[Egon247]

Just a quick thought....

 

While it's in a bzillion pieces, are there any worthwhile mods that are worth doing? 

I've heard that the big cbr can get HOT in traffic (living near Dartford, read that as "pretty much constantly"). 

I'm considering fitting my own alarm immobilizer as there's plenty of space to hide stuff whilst it's sat there naked! 

Edited October 22, 2024 by Egon247
Hot not harm. Fat fingers lol

[RideWithStyles]

A tracker id be pushed to as all that is to connect to the battery (plus knowing where it could be at any time is good) but an immobiliser or an alarm? No chance worst piles of shite you can do to a new bike let alone an old one with corrosion and resistance in the wiring systems…

One of the garages I use regular jobs to do on bikes week in, week out that come in is to rip out those shite parasite's.

[Egon247]

Today was a paula Abdul mode day:

 

"Two steps forward and one step back"

 

While I'm waiting for the carb kits to turn up, so thought I'd take off the radiator and fan to see what it looked like.

Oh dear. 

Much crusty. Amazingly the only broken bit holds the rad guard at the bottom, so may be able to improvise and/or improve. 

Wire brushed the bejesus out of the crusty fluffy ally bits and gave it a light coat of vht black.

Only it wasn't vht it was just ho hum vinyl black from Halfords.

Oh how I laughed.....

 

Here it is in its full on crusty mode...

Shineeeeeeeey....

[Egon247]

Sorry for the slow updates, it's half term and the wife's a teacher, so we gotta do the family thing.

 

Little bags of shiney things have been emptied and bits installed. Had to do a reality check on my head a couple of times as the mixture screws only go in one side but there's a hole that's not tapped on the polar opposite of the carb. Had to laugh.

The rail that hold all the carbs was looking a bit grim so that got some paint, just something I had laying around, it doesn't matter as you're not gonna see it unless it's all going wrong

Waiting 24h for that to go off and then the fun job of looking at the 32 photos I took to see where all the joiners and vents go. Might rig them up to a little tank to make sure it's not leaking too. 

I'm going to try the original rubbers, they've had some Autoglym bumper gel on them for a bit, forget who suggested that, might have been in the 600 thread.

Whoever it was, thank you.

Yes, it was the 600 thread. I tried it out of desperation but was delighted when it worked for me. I hope it works for you too.

Really enjoying your updates. I'm still on the lookout for this winter's project but I'm thoroughly enjoying yours for now.

[Egon247]

I have PTCD 

Post Traumatic Carb Disorder.

 

That was not fun.

Got it all back together, after half an hour of debating whether or not the orings in the jet kit were for the fuel feed pipes, the vent pipes and the joiners. Seems they were. 

Yay.

Only I then realized that the choke bar needed to go in. No worries, that'll just poke, it'll just, ah. Bugger. It has a bendy bit in the middle and it needs to go on while your other 8 hands are putting the carbs back together.....

 

Yay. It's on. Now for the choke links to hold it to the bar.......oh. two out of the four were in the wrong place.

 

All apart again. New words were learned by next doors children.....

 

 

Apart again. Taking my time. Taking care. Slowly slowly monkey win or how ever it goes.

 

Yay. Choke works, butterflies all work together. JIS screwdriver still in the garage and not in orbit.

Only a few bits left over too....

 

Carb tops off for a coat of VHT (right one this time!) and tomorrow I'm attempting to put them back on the engine....

This is great mate, it'll be running soon.

Hopefully. I'm aiming at having it all good for my 50th at the end of April...

 

[Egon247]

The carbs are in. On. In?

So after moaning that the airbox doesn't come out to remove the  carbs, guess what I forgot to do?

So technically they've been in/on twice.

Rubbers needed some persuasion with the heat gun but hey, job done. 

Got some family stuff to sort so might be a while before the next installment...

[Egon247]

Today was "let's see what the tank does with some fuel in it" day.

 

To which the answer is decisively "nothing"

 

I kinda figured that the fuel tap would look like the carbs, if not worse but held a straw of hope I was wrong..

Lol.

So the comedy is, once you've got a litre of fuel in it and the tap doesn't work, you have to undo the tap and improvise. Got MOST of it in a container.

Glad I don't smoke anymore

So, fuel tap off and stripped down carefully. Everything is intact but very sticky. I think the o ring from tap to tank is utterly shot so I'll need a new one but the rest looks ok. Removed a sludge fest from the bottom of ith inlet filter things too. 

Pic1 is sludge from there filter fillers.

Good clean and back together, just need that tank oring and I might have a shot at starting it up ..(then oil+filter change after that!)

[Egon247]

It runs.....sort of.

Smoky as hell but it's alive.

Better change that oil , I think.

It sounds unhappy at being woken up.

Waheeeeey, that's a good start, albeit a smoky one. 

[Egon247]

I'd post a video but it won't let me.

Just make vroom vroom cough cough noises ...

[Simon Davey]

Wonder if that's burning oil, or unburned fuel that's causing the smoke?

I think it was the stuff I put down the holes when the plugs were out and some of the stuff I'd been using to clean up with, mixed into the fuel. Wasn't an oily smell, was a bit more pungent than that. (My rd250lc used to grenade a lot, so I know what oily death smells like. )

[Egon247]

Carbs are way out of balance too, I don't think my petrol can has been used in at least 15 years, so it could be all sorts of things

Oil n filter next, that oil is 16 years old....

[Egon247]

Today was "front brake foray" day.

 

So the fronts were both seized on. Judicial use of a deadblow hammer persuaded them to let go of the disc and eventually they came off.

 

Thankfully someone has fitted Goodrich hoses at some point so I don't need to worry about those.

 

I tried the block of wood and airline trick but those pistons were not budging. No siree. 

So I gave in to inevitably and had to use a pair of mole grips and a big driver to wiggle them free. Looks like the dust seals had been put back in badly and were hanging out of the bores between the pistons.

 

Meh, add them to the list of things to buy.

 

All the small parts were plopped into the ultrasonic cleaner and came out quite nicely. 

The thing that struck me though was how small the pistons are. I mean, she's a lump and iirc about 130bhp, those pistons just look waaaay too small.

I'll get some stainless ones along with the seal kits too. And a master cylinder rebuild kit. 

 

 

[Simon Davey]

For future efforts removing the pistons, I discovered that pushing them right back in to the calliper, actually makes it easy to then slide them all the way out.

I've done this a few times, on the same bike, in the space of a couple of weeks . Turned out my lack of pressure issues were caused by warped disks.
