subheatadey Posted December 29, 2020 Report Share Posted December 29, 2020 Hi there, New member here, I've just bought a project bike it is a Ossa Mick Andrews replica. I think it is a Mk 1, strangely it hasn't a side stand lug mount so I assume it never came with a side stand mount? It needs a bit of work but the bones are there, no spark so today is pulling the very stuck stator and hope it is just cut wires at the bottom, definate ly will be running the wires out of the front. Anybody here who knows about Ossa as I no nothing at all Quote Link to comment Share on other sites More sharing options...
subheatadey Posted December 29, 2020 Author Report Share Posted December 29, 2020 I'm new to trails bikes, it came with the powder coated frame so I have no idea if that's good or bad I was hoping to get it started over the festive but it seems like the Stator is fubarred? I did read somewhere that they have a diode that can be replaced but it looks like a sealed unit? So I am looking for another stator if anyone knows of one or where I can get one from that would be a great start? Quote Link to comment Share on other sites More sharing options...
woody Posted December 29, 2020 Report Share Posted December 29, 2020 You can get the stator repaired by Bradford Ignitions, I had one done some time ago and it still works Or you can buy a complete replacement aftermarket ignition from In Motion The bike looks to be in good unmolested condition Quote Link to comment Share on other sites More sharing options...

Anybody here who knows about Ossa as I no nothing at all Not an expert on Ossa by any means but I do have a mk 2 and have gathered some info and pics over the years, your bike looks like a good starting point for a resto. Your bike certainly looks like a MK1 due to flanged Amal carb and the solid fork bottoms. Have a look at the attached brochure shot that shows a side stand for MK1. I think your round rear frame hoop over the guard might be bent down, but could be just the pic angle or those universal alloy guards. Attached is some pics of my rear frame hoop, you got to remember that the seat is attached by two bolts that go through the rear guard and the flat frame hoop. Hope this is helpful. Edited December 31, 2020 by fourex Round and flat frame hoops. 2 Quote Link to comment Share on other sites More sharing options...
feetupfun Posted December 30, 2020 Report Share Posted December 30, 2020 I agree with the identifying features of a MK1 mentioned by fourex and add that the shouldered rear rim (and maybe the front rim?) are also a sign of a Mk1 MAR. The Mk1 came with a fibrous bashplate that has fortunately been replaced with the later aluminium item on yours Quote Link to comment Share on other sites More sharing options...
subheatadey Posted December 30, 2020 Author Report Share Posted December 30, 2020 Cheers guys for the replies and Happy New year 'almost' to you. Yes the rear mudguard frame is bent down, I may have a go at straightening it but it may damage the powder coat so I will see how it goes. Strangely for the side stand or rather lack on one there isn't a lug on the frame to bolt one on to which is curious? On the plus side I am hoping the stator is good now I have pulled it off it appears to be just broken wires I am now with spark, I assumed it was the stator as I did as resistance check on it and was getting nothing but having read a little bit I assume it was because of a diode in the stator stopping getting a reading? Also the guy I bought if off told me it needed new rings, but I realised the decompressor was sticking. Its got perfect compression so all good on that front. So next tasks to do, 1. The coil HT lead was cut probably having melted from the exhaust so I've just ordered a HT connector which should sort that. 2. The front wheel is a bit bent out of shape, I would like to keep it I don't suppose anyone knows anyone who refurbishes wheels or if this is possible? 3. The rear brake cable is a conundrum, I don't suppose anyone has a picture of what it looks like, I will probably make my own out of a clutch cable, there doesn't appear to be any adjustment on the brake lever? I assume there should be some type of adjuster between the brake shaft and the frame? 4. Bash plate is very bashed and it has been welded a number of times, so time to get out my TIG welder, but first I need to get some more gas.

fourex Posted December 31, 2020 Report Share Posted December 31, 2020 (edited) If you left click on the brochure pic it should enlarge enough so you can see the bracket on the left side of the swing arm on that shot of the plastic bash plate. Otherwise here's a pic of the mk 2 side stand bracket, it looks the same as the mk 1 brochure. PS: Search the Ossa forum here regarding rear brake cable arrangement, it's another of those odd things that Ossa did, like 12mm axles. I'm sure I read someone asking a similar question in the last year or two and the responses and photos made it clear. Venhill make and sell the rear brake cable.

feetupfun Posted December 31, 2020 Report Share Posted December 31, 2020 Yes it's a normal thing to refurbish wheels. It's an economical way to get your bike looking good and nice to ride. Many riders do their own, motorcycle workshops can do it and there are even places that specialise in doing it. 1970s Spanish trials bikes are an amazing source of discussion points and the rear brake actuation on the MAR is one of the best conversation starters. The cush drive mechanism for the transmission is another. Quote Link to comment Share on other sites More sharing options...

Steve Sell makes a same diameter but much stronger rear wheel spindle which in my opinion is a must have on a bike that is ridden. If the original one is not already bent it likely soon will be, Steve is the go to person for all things OSSA. The rear brake cable on the MAR is much heavier made than a motorcycle clutch cable but Steve should have the correct one. Quote Link to comment Share on other sites More sharing options...
subheatadey Posted January 4, 2021 Author Report Share Posted January 4, 2021 Ossa MAR Mk1 Rear brake pedal no adjustment?? Hi Guys, I must be missing something or it was designed like that, but there appears to be no brake level stop other than when the rear brake lever hits the cross tube for the swinging arm?? All very strange ? Quote Link to comment Share on other sites More sharing options...

All very strange ? On mine the brake pedal up-stop is the engine cover. It's the perfect height with the standard footpeg location. I've just now looked at you photo and can see that your engine cover is missing the section that the pedal usually comes up against as a stop Edited January 6, 2021 by feetupfun Quote Link to comment Share on other sites More sharing options...
subheatadey Posted January 6, 2021 Author Report Share Posted January 6, 2021 (edited) Hi, Yes I have now discovered that. Strange way to do it but keeps it simple I guess, so I am now on the lookout for a sprocket case cover, if you hear of one and could let me know that would be great.

subheatadey Posted January 11, 2021 Author Report Share Posted January 11, 2021 It is too cold outside, so I brought the Ossa into the house fortunately I cant afford carpets. But its lovely having central heating, even better if I had a decent garage with heating but then I would probably end up living in it Quote Link to comment Share on other sites More sharing options...

subheatadey Posted January 11, 2021 Author Report Share Posted January 11, 2021 Once a few years ago, now I can do what I like ? I keep thinking whether I should knock the wall out so I can get my Land Rover in to replace the bulkhead Quote Link to comment Share on other sites More sharing options...
