I have been sitting on this for about a month now and finally got my finger out after mastering the art of procrastination over the winter. I fell heir to this from my brother who built a 31k/rgv Hybrid last year.(He is a forum member but has been inactive for a while due to health reasons) He had plans to build a "standard-ish" bike using all the parts left over and other bits sourced from here and there, but the goalposts have now changed a bit and so it has arrived with me. So, what do we have?
I dragged out some of the parts between rain showers today for a couple of pics (there are another three boxes in the shed) and also to look at what we have for starters. Nice German frame with docs from a fellow forum member(needs painting), f2 front end, several looms switches and electrics, 2 sets of clocks, tank (rough), seat (worse) engine in bits with as many parts missing as there are present, and a mis match of parts from various models from as many years but with most of the parts there to get me going.
Never built one of these before but already stared sourcing the easy parts which is a start.
Not intending on a concourse rebuild as this is a pure mongrel but will follow the guidance and professional attention to detail shown on here by some real talented individuals and hopefully turn out a nice useable machine to join the LC and diesels when I need my speed fix.
I am also in no doubt I will get stumped along the way as to what bits go where so a few questions will be thrown in to the gurus out there
This is the start of either an enjoyable project or a total nightmare, wish me luck.
Thanks guys for your words of encouragement, I am looking forward to this one.
Yes Matt, more than happy with a well sorted mongrel as I won't need to worry about the green bolt, thread counters comments ha, and I can pretty much do my own thing. I don't even think many of the parts I have left the factory together anyhow so happy days.
Already sent some parts off to Dave at Mutts Nuts, and Dejan came up trumps for some other things as well so it has begun.
Plan is to do the engine first while prepping the scabby bits for paint, and a target time for OTR in the summer (hopefully) Better get a big bag of popcorn Alex as this will take a while lol.
Plan is engine first. Crank looks goosed so off for a rebuild or replacement, whichever is least painful.
Cylinders are just a tad under 65mm and looking a bit worse for wear so off for rebore as well, if they can take it!
Then pulled the crankcases and gearbox internals and gave them a good going over seeing what is needed for the rebuild. Looking for the usual good and bad bits, noticed that the cases were not a machine matched pair. Ahhh bugger!!
I am not sure where the cases came from during the gathering of bits but I'm not keen on re-building on a mis matched set. Thoughts from the forum on this would be nice to hear. It would probably be fine but my OCD would not be able to live with it. So after some tentative enquiries I think I have sourced another set.
Engine on the back burner for now then so I'll just get on with degreasing and cleaning in prep for painting.
I agree that they would probably be absolutely fine and they are in excellent condition, but as already that stated my utterly unnecessary OCD would annoy the sh*t out of me so a replacement matched pair will be used.
Once things are moving I will probably sell these on and try to recoup some of the cost back.

Nice project, love a mongrel bitsa.
Got a mongrel hybrid on the back burner
Probably best finding a replacement set of cases. I know that one has ran in the past but without pressure testing before strip or feeling how a newly built crank "feels" in them it's a bit of a gamble
After spending some time hunting for spares yesterday, I had a go at cleaning a couple of particularly manky parts using an untested degreaser (untested by me that is)
Got this stuff from Bilt Hamber when cleaning out an old fuel tank and thought I would give it a try on some oily bits. Water soluble and biodegradable apparently so a little apprehensive on how good it would be.
Cushdrive was dirtiest thing in the box so gave it a go
Spray on and left it a while to do it's thing. After about 30 mins set about it with a wee paintbrush and worked it in with a few more sprays.
A quick rinse off and rub with a cloth and result:
Is it as good as Jizer? Well maybe not as it needed a bit of work but an it is definitely an alternative which is marketed as being a bit more environmentally friendly (for a 2T rider at least ha!)
While waiting for the engine parts to start arriving, I have been taking frame and suspension bits apart for cleaning/refurb and prep for paint. The dogbone and H linkages were a bit of a swine as some parts were well greased and other parts seized solid. After a bit of heat and "gentle" persuasion with the old 2lb hammer and drift, the smaller H bushing came out. Unfortunately the brass/copper bushes themselves inside the link knuckle thing, were less willing to move. I used a junior hacksaw to cut through the bush and then long drift punch, and out they came.
Some new bushes now and we are good to go.
One thing concerning me however is the condition of the surface of the dog bone link arms where they go through the bushes in the swing arm. They look pretty rough
I am unsure whether they will be a nice fit in the new bushes with no play, or they will tear them up in no time requiring another strip down sooner than I want. I don't know if I would be better off trying to source a good second hand set from the 'bay or get them machined and get some matching bushes for the swing arm made up at the same time. Something to ponder while my shopping list continues to grow.
On the plus side, Philmil has come up trumps with a clock/headlamp/fairing bracket solving one of my many conundrums. Thanks Phil
i have these, look a bit better than yours, if you want them lmk, might be usable not really sure, i have the h shaped linkage also not sure on condition, and a shock i believe lmk
Cheers again Fozzy for hunting out and posting pics of some parts which I need for this increasingly challenging rebuild I have lumbered myself with. Those certainly do look better than the ones I have at present
A mate of mine is raking through his pile of spares as he thinks he might also have a pair somewhere so I'll wait to see what he comes up with and I'll PM you either way.
