    I picked up this 1989 mc19 as a parts bike for another mc19 build, but after getting it home I decided it probably wasnt a bad bike to fix up instead of parting it out for another project.
    20190513_163023.jpg
    20190213_125927.jpg When I went and looked at the bike he said he couldn't start it because the fuel pump had died the day before trying to start it for another potential buyer but he assured me it startered and was a solid runner that he used as a daily.
    The fairings weren't in great shape having a few cracks and a small piece missing around a bolt hole in the front fairing the rear indicators were missing along with the lower part of the inner gaurd that holds the licence plate and reflector.
    Apart from that the bike was complete, so I handed over the cash and loaded it in the back of I'm ute for trip home.

    A week later after deciding it was going to be my new project I started stripping it down so I could get a good look at it and see if I could get it to turn over.
    Very quickly did I see the bike was In much worse shape then I could have imagined and the bike had been in an a accident at some stage and had some of the worst repairs I had ever seen.

    First I had noticed the rear sub frame was bent and on closer inspection it had been cut and had another subframe very very very poorly welded on.
    20190220_120509.jpg 20190220_120518.jpg

    Instead of removing the inner gaurd to do that classy repair they just cut a 100mm section out to Weld it Hahahahah.

    The next thing was the wiring, it had been hacked to bits the indicators had been removed and it looked like he had tried to put a led set on it as the harness had been cut into and had dodgy connectors all over the place he obviously couldn't get it working so I'm assuming he took the indicators off and left the wires behind.

    There was also a pilot switch wired into the thermo fan so it could be manually turned on. (For traffic use he told me).

    After removing the rear subframe and tossing it straight in the bin it was time to have a look at the engine, at this stage I don't have high hopes that it's going to start. While checking the usual stuff prior to trying to kick it over I noticed the reason the fuel pump had stopped working was because it wasn't there.....He had the main fuel line from the carbs plumbed straight into the tank, no pump no fuel filter nothing hahaha.

    So instead of trying to start it I pull the carbs off and put them in the ultrasonic parts cleaner.
    20190220_120549.jpg 20190220_131950.jpg 20190220_131855.jpg

    It was my first time I've used it and I was actually really impressed with how well it worked for an elcheapo eBay
    inCollage_20190220_155019383.jpg
    I put the carbs in for 3 20min cycles twice in heavy duty degreaser and once in water this was from the second run I forgot to take a pic of how much stuff came out on the first go.
    20190220_132332.jpg

    Next will be a clean up of the whole bike and put the carbs back together and back on with a new fuel pump and filter.

    Needless to say I overpaid for this bike and I should have been a lot more thorough before handing over the cash but lesson learnt, however it will be well worth it when it's done.

    Cheers mate but I've already picked one up along with new inner wheel gaurds, indicators, and pretty much everything else that was missing/unusable from the sub frame. I'll do another post tomorrow with a bit more progress

    Don't get me wrong I'm pretty pissed about it because a quick fix has now turned into somewhat of a full rebuild and has taken my focus away from another project, but I'm a pretty easy going guy and it looked like old mate was doing it pretty tough so at the end of the day I don't mind to much plus I like a challenge. Might be a different story if the engine is shagged. But I'll cross that bridge when I get to it. Lol

    Fair call. Hopefully it all works out for you and the bike. What city are you in?

    So got a bit done today gave it a bit of a clean because the engine was filthy it's not micky mouse but it's a lot better then it was 20190319_165108.jpg 20190319_171913.jpg

    Sandblasted and gave the new rear sub frame coat of paint.
    20190222_115939.jpg
    20190328_121627.jpg

    Carbs went back together and gave the vacuum cover a coat of squiggle paint which I'm not sure if I like it not but it's on now. 20190328_121601.jpg
    New carb boots, fuel pump (eBay special so I will see how that goes) new fuel hose and a oem filter which is from a cbr600 which is compatible according to honda.
    20190415_134222.jpg 20190415_134231.jpg 20190514_141759.jpg
    I installed it all and kicked it over and I couldn't beleive my eyes it started first go no trouble at all the engine surprisingly sounds really good but I havnt done a comp test yet so see how that goes.

    Now I'm not actually sure of what this filter going to the top of the carbs is but when I opened it up to clean it the filter literally disintegrated at the slightest touch, I couldn't find anything online to replace it with but I had this filter medium laying around so I doubled it up and have used it. Can any foresee this being an issue at all?
    20190514_145243.jpg 20190514_145407.jpg 20190514_145421.jpg 20190514_141812.jpg
    Next the new inner gaurds went in the subframe and the loom was put back in place along with a new battery. I still havnt fixed the hacked part of the loom which goes back to the indicators but I'll sort that when the fairings go back on. 20190514_141702.jpg 20190514_141651.jpg
    20190417_164806.jpg
    Now to the front of the cbr, the front wheel was removed so I can have them Powder coated, the wheel bearings are flogged so I'll order a new set for the front and back and I'll do the headstock bearings while I'm at it.
    20190430_150620.jpg 20190430_152545.jpg 20190430_153200.jpg
    While the front wheel was off I removed the forks which probably need to be rechromed and have new seals put in, but might just be worth trying to source another set that is in better nik but see what happens.
    The radiator needs a new coat of paint so it came off along with the shroud. I flushed it and coated the tanks in paint stripper to get it ready for paint. 20190514_133755.jpg 20190514_133854.jpg 20190514_150039.jpg 20190514_150041.jpg
    When I flushed the radiator some of this stuff came out I have no idea what it is some type of glue maybe? It was Softish and broke easily enough. 20190514_134710.jpg
    Also while the radiator was off I replaced the o rings on the radiator hoses where they bolt into the block as they were hard and cracked.
    The exhaust came off next, I gave it a hit with a wire wheel in the drill and it git a coat of heat proof black. The can had also been wrapped with a stainless cover I assumed it had been dropped and was damaged underneath but when I drill the rivets out it was in better shape then the cover was. 20190327_134824.jpg 20190514_150649.jpg 20190514_150705.jpg 20190515_171042.jpg

    Im back at work now for a couple of weeks now but should have the bearings and a few other buts and pieces ready to go for when I am back at the workshop.

    Its a bit hard to tell how good/bad those forks are from a pic but try polishing them with a bit of crumpled aluminium foil and WD40 or Inox liberally sprayed on beforehand

    That little box is the air breather for the carb diaphrams. What you've done there will be fine.
    The fork legs may clean up ok as Grey suggested, just needs lots of rubbing.
    What comes out of a 30 year old radiator is anybody's guess. New rad and hoses available pretty cheap on aliexpress.

    Ok cool I'll give it a go you can't really see the pitting in the pic. In hind site it's probably not that bad but there is putting there I don't think will come out. But I'll give it a red hot crack. Cheers
