Thought I'd start a build thread, I've been a member on here for a couple of months and can't believe the wealth of knowledge on here and wanted to share my penny's worth and will always be open to ideas and tips and tricks
As with many of my ideas, this one came to me after a few beers and increased amounts of boredom during my rest days off shift. After a couple of weeks of collecting inspirations and ideas from social media and the inter webs I had a general idea of what I wanted to achieve.
Here is just a few inspirations of what I want to achieve.
Cue the popular auction site search. Weeks went by and nothing in my price range or scope for a project came around. I was looking at CBs and CX's thinking I should be able to work out how it works and learn the Engineering behind them. Then Finally, (using my work time efficiently) I found the one, a CB 550 freshly imported from New York (I'm From England if this hasn't become clear). Immediately I impulsively bid and won. What had I just let myself into!?
As you can see its a bit of a shed and had been raped for parts by PO.
Let the Tear down begin,
I started removing the nonessentials, stuff I know I wouldn't be keeping and plan on selling in the future. Head light bowls, Cabling and such. This is where I started to unearth some absolute horrors and levels of bodgery that I can't begin to comprehend. Such as the Exhaust welding that looks as if its the pigeons had got hold of it.
Out of the four exhausts, 2 of them are U/S, the others are probably salvageable.
Anyway back to the strip down.
I removed the gaiters to find some nasty corrosion, I'm unsure if this can be removed and treated or just get some new stanchions?
Of course, all seals and bearing will be changed. Probably well over due anyway.
Turned my attention to see how the steering head bearing were and as can be seen, not looking very tasty.
Stem and triple clamps removed! Time to move on.
I removed the carbs to give them a good once over and check if I could clean them myself or would need a good sonic bath
Turns out these Carbs are pretty gammed up to the point where one of the slides are stuck inside the chamber. All the floats are completely seized and no matter how much soaking and fettling I give they will not budge. So off they go to a cleaning service south of the country.
Whilst they are being taken care of, I moved on the the engine to check on the condition. The guy I bought the bike from made no attempt to start it, just said the compression seemed okay and selects gears well. A bit vague for a description but enough of an excuse to rip into the motor.
Heads off
Pulled the Cam shaft out to give it a good look see and found some nasty pitting, I/s this to be expected on a 30,000 miles 44 year old bike CB550?
Irregardless I ordered a secondhand cam shaft with followers from the popular auction site and continued my investigations.
Theres a lot of carbon build up, Is this a normal amount of carbon to see? or is there something not quite right?
Pulled the cylinders off and set them aside
Clutch basket and selector system off next
Pulled the sump off to check for nasties
Oil pump filter seems surprisingly clean, but the sump told other stories, Lots of nice sludge and a big lump of metal, I didn't take any photos at this point, I was too involved in finding where this mystery metal came from.
I split the case after a good few hours of attempting to hunt every single bolt down.
Any ideas on where this mystery metal came from?
How about now?
Turns out the selector fork isn't happy. My question is this, How does this happen? and from the pictures is there anything I should be looking out for or should consider changing while I'm this far inside the engine?
Back to the popular auction site for some selector fork hunting
Can anyone tell me if the journals for all the bearings are removable? Or do they require machining?
Will update when i'm back in the shed
