I've just re assembled the front wheel and put it back on my bike. Is it me or does everything seem a pain to do on this bike!! I ended up having to slacken off both fork clamps and move the stanchions upwards just to align the brake plate, admittedly I haven't yet fitted the rear wheel. Then I struggled to fit the spacer and speedo drive, there didn't seem enough room. I've given up for today, maybe a couple of pints and some sleep will help!!

How much gearbox oil should I put in my 2013 bike, it has had the 2014 mods done, ie the breather near the front sprocket has been blocked and a new breather fitted round the back of the engine near the kickstart

Me again ;-) Sorry for all of the questions! The gas light is always on, but the tank is full...and I have gone through more gas than is just in the lower tank (2L I heard) and I haven't run out. Any ideas? BTW, the other lights work for blinkers and lights, so I don't think the bulb swapped position. I think there are only 3 bulbs (nothing in top right). I do see that there is a sensor in the bottom tank and appears to be connected to the correct light (green/black wire if I remember). Thanks!

I have looked at the manual, but the description and pictures aren't enough for me to really understand. Is the hose that extends from the front of the "top tank" a vent hose? From the manual, this looks to be yes. I have a hose extending out and it looks correct to me. On the bottom tank, there is a metal "nipple" (near the top) that rotates 360 degrees and when the tanks are full, does leak gas out of it. The nipple looks like it would have a hose attached to it, but there is none currently. How should this be setup? Do I just point the nipple up/front and deal with the gas that sloshes out? Or, if this is a vent, should it also have a hose? I can try…

Hi, I have a 2012 Explorer and bought the regular tr280 brake pedal. Anyone know a link to any instructions? Or a video? Do I have to bleed the brakes or is this just a bolt-on? I didn't want to start removing things before asking ;-) Thanks!

I have the 2011 280i and it appears to only run one bearing on the disc side, which I have replaced. I see there is a conversion kit to upgrade to a 2 bearing type but can`t find anyone that has it in stock. Anyone know where I can obtain this kit at a reasonable cost with shipping to the UK ?

anyone brave enough?

Almost my only compliant about my Explorer is the rear linkage. It is probably just fine for most trials- but I ride it a lot and in a lot of mud and water. Those bushings are ok if you take the thing apart a lot- but I'd rather have something a little more robust and with zerk fittings. Anyone looked at coming up with something else? Or no issue for anyone else? Bearings and zerks would be nice. Even just zerks would be ok, since I could hit it every ride. Mark

Hello all- Is there a trick to reassembling the '72 MAR 250 kick starter lower and upper. The two small springs and bearing are giving me fits. Sure don't need any more of those! Any help appreciated. Herman

Hi, hope someone can help. I'm about to put the tyres on my '75 mk2 mar. There are 3 holes in the rim, one for the tyre retainer, one for the valve and the other one??? I only took one retainer off so am stuck as to what the third is for, any suggestions? Cheers, Nigel.

Does anyone know where i can get the plastic frame trim the clips into the top of the frame cheers

Hi, Does anyone have a recomendation for Black Exhaust paint for the middle box and silencer on a MAR, most of the exhausts paints seem to be Matt and I was trying to match the original gloss

Does any one know where this cable/spade connector go it a tr300i the black and blue to the coil but what about the orange, stripped the bike down and now can t remember where it goes ,cheers

Has anyone replaced the fuel filter? (Modern OSSA) I'm getting a 'fuel pump over current' which on every other bike I've ever had means a partially plugged fuel filter. I believe it is more time consuming than popping out the gearbox. Bike still runs great- I wouldn't have known but I put the software on to check things out. (Around 270 hours) Mark

I'm restoring a TR77 from a box of bits and after cleaning up the crankcases I found cracks on both sides where the cylinder studs go in. Is this a common problem or have the studs been tightened up by a Gorilla with a 10 foot long wrench? Work to do :-(

Hi all - I am going to replace my old Amal on my '72 mk1 MAR and wondered if anyone could advise on the best make and settings. The current carb is a flange fitting 26mm. Look forward to any feedback. Thanks

Hi all I'm new to the forum (and Ossa's) and hope you can help. I'm restoring a TR77 that I got in pieces 15 years ago and am finally getting it together. The engine is stripped, the crank rebuilt, and the main bearings and other bearings in the casing seem easy enough to source, but I'm puzzled at the blind needle roller pictured below. Is this an open-at-both-ends bearing fitted up against a blocking end piece, or is it a one piece closed-at-one-end needle roller bearing? Also, does anyone know what number bearing it is so that I can buy one from somewhere? Is it easy to remove? Any other tips or comments you have would be much appreciated Thanks Adrian (P…

Does any one know how to get the chain tensioner back on almost got it then the spring slips and I end up stabbing my hand .

Hi all, can anyone tell me where I can buy a rebuild kit from for a mikuni carb as fitted to my '75 Ossa mar? Cheers.

As above, what oil is it needed for the engine / box. ?
