[Reed valve blades]

My OSSA MAR 250 has Harpowa (Kershan Bradford) reed valves fitted. Does any body know where I can get replacement blades (petals) for them (UK) ?

[OSSA MAR max revs on startup]

Crank seals replaced. First time bike has been run in at least ten years. (Not by me). After several tries starting, poured a little petrol in plug hole. It then started but just proceeded to rev until I hit the kill switch. Left it for half hour or so, started again with same result.

Amal carb fitted. Needle was on bottom setting. I've now moved it to middle but bike won't start now. Not sure if it's because I've moved needle position or just that it's a pig to start anyway.

[OSSA MAR max revs on startup]

When I start my OSSA MAR the engine revs just keep on climbing until I kill engine. Carb slide working OK.

Any ideas.

Thanks Trialman. I was looking at these, but wasn't sure if they'd do the job. I've now ordered one.

Thanks Woody. Unfortunately I don't have any old clutch plates. If anybody does and can send me one, I'd be grateful.

Hi

l'm having trouble tightening my clutch centre nut up to the correct torque (65lbf). Can any body suggest a method or know where I can get a suitable clutch holding tool from? I'm in the UK

Thanks Woody.

[250 MAR timing]

Hi

What is the correct timing for the stator on a 250 MAR?

The flyer manual I have (250 and 175 engines) mentions "Plonker, Pioneer and Stilleto" which of these should I reference for working on a MAR?

regards

Gordy

[OSSA MAR headlight mounting]

I have fitted a headlight to my OSSA MAR using the rubber straps, but it is very loose. I cannot see any way of tightening the straps. Am I missing something?

Thanks guys. I've done them to 25 bpf.

[1977 OSSA MAR MK3 Rear Brake Cable]

Hi Guys

I am rebuilding my OSSA. It never had a rear brake cable when I got it. I have the rear brake cable with the nipple one end and adjuster thread the other. I seem to be missing some parts like a 9mm barrel for the thread to pass through and a nut for adjustment. Can anybody advise?

See attached pictures for frame and hub cable fitting points.

Thanks

[Rear Sprocket Nut Torque]

Hi Guys

What are the torque settings for the rear sprocket on a 1976 OSSA MAR?

[Felt washers with sealed bearings?]

I have fitted sealed bearings in my OSSA MAR mk3 front wheel. Do I need to get felt washers for when I fit the wheel back into the forks? If so where can I get them from? Note: This is a restoration I'm doing and there were no felt washers when I took the wheel apart.

[Tyre pressures for road use]

Thanks scifi.

[Tyre pressures for road use]

I have Pirelli MT43 tyres to fit on my OSSA MAR mk3. What tyre pressures should I use for road use?

[Ossa MAR ..restoration advice please!]

Hi Scott

I am restoring a 1976 OSSA MAR mk3. It to had been painted black and I rubbed it down ( not to bare metal) and sprayed it with this from EBay, using the primer suggested from the same supplier: FORD 3 SILVER FOX Aerosol Spray Paint 400ML Direct Shine Gloss https://ebay.us/iZJdtU

3 coats primer with 20 minutes between coats and 3 top coats with 20 minutes between coats. I didn't rub down between coats unless I got any runs. The attached picture shows the finished frame. Like you I want to do everything myself, so lots of reading on the internet etc.

[OSSA MAR MK3 Horn Mount?]

Not powder coated. I rubbed down the paint on the frame, it had been (hand ?)painted black. Then sprayed it with rattle cans. Three coats of primer, four top coats (silver fox).

Thanks for the info Woody.

[OSSA MAR MK3 Horn Mount?]

Does anybody know what the bracket shown in the attached picture, on my OSSA MAR MK3 frame is for? Is it for mounting a horn? If so, does anybody have a horn that fits?

[OSSA MAR steering bearing felt seal and cover]

Thanks.

[OSSA MAR steering bearing felt seal and cover]

Hi

I am rebuilding an OSSA MAR MK3 and am missing the felt seals and covers for the steering assembly upper and lower bearings. Any ideas where I can get them from.

Also after lights and horn and switch, and, lights and speedo mounting rubber brackets.

[76 OSSA MAR Frame Colour]

Thanks for the replies and thanks to Woody for identifying a paint.

Yes the upper shock mounts are level with the lower side panel screws on my frame.

[76 OSSA MAR Frame Colour]

Can any body tell me if the 76 OSSA MAR was available with a black frame? I am starting the restoration on one and it is painted black. All the pictures I have seen seem to show a silver frame.

Either way can you advise the paint type/ colour?

I'm also after speedo and lights.
