OSSA

Since there doesn't seem to be anymore rear mudguards or side panels anywhere around right now- I'm fabricating a once pice setup from aluminum. I've never done this sort of thing in aluminum (I have in fibreglass)- so,it is sort of a learning process. I made up a template, then cut the three pieces from aluminum sheet. Now I'm welding the side panels to the mudguard. They both use the two side screws by the end of the seat, and overlap. Might not be the best looking (at least this first try)- but I'm hoping will work well. My mudguard broke and I have it pieced together (plus a new spare, but don't want to waste it) The bike is just so darn fun- I sure hope th…

Well, I sold my 2014 Explorer last week. I really have liked that bike- LOTS. It has been pretty darn good, with the linkage the weak spot for how I was using it. If they had a more robust linkage with real bearings, I think it would be a LOT better. No engine problems at all, just a broken return spring for the gearbox. I had no plans to sell, I even bought a Beta 4T to ride so I would not put so many hours on it. But most of my buddies ride enduro bikes, so after getting a Beta Xtrainer, I found I just wasn’t riding the Beta 4T trials much. So I sold it. Someone was interested in the OSSA- and I decided to give electric a go. Electric-Motion has a mo…

The explorer is based on the trials bike and I made the conversion.... 4 screws for the sub frame, one in front of the tank and a hidden one under the seat, two cables, open the fuel line with snap closing and you can take away the Explorer kit. Trials plastics can be mounted on the normal fixing points, for better slow motion trials I prefeer changing the front sprocket from 11 to 10 teeth. A real dual purpose bike

Hello people, I'm tidying up a few wiring issues inherited from previous owners and I've hit an issue without an obvious solution. Can anyone tell me what the MIL wire from PIN22 on the ECU is supposed to do? It's currently connected in a very nonsensical way and I'd like to understand how it should be connected. Does anyone have specific knowledge? I've a loom with the six pin diagnostics connector and the easystart system if it helps. Failing that, does anyone know what happens to pin 22 in the cases of a fault and no fault? Thanks in advance. Cheers... Paul

Anyone know what other bikes use the same front brake pads as the 15 Factory 300? They do not have locating pins, but rather rounded areas that lock into the caliper.

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.

Folllowing on from the previous discussion, I thought I should sort some out for my fibreglass tank as the alloy tank ones are a different shape, I could vaguely make out the shape of some original decals on this tank so to top half should be about right. However going through my Spanish Trials Bikes Book and The Ossa Collectors Guide book there are no really good photos of the tank for the lower half. So based on what I could see do these look right? They're going to be a right bugger to fit (nicely) due to the shape of the tank, i managed to crease these doing it quickly...

I have a Caswell-lined fibreglass tank and wondering if I should, or need to, remove fuel mix while storing over the winter (Canadian) and if so, should I replace it with something or okay to leave empty. For my street bikes I just top up tank and add a bit of stabilizer. I asked my neighbour who owns a boat and he says it should be fine if it's treated/lined as it protects from ethanol. Thanks in advance.

Anyone thought of studding their tyres on their TR-series for some more serious winter fun? I have many frozen lakes around for sliding practice, plus my own garden to play, both are very icy and slippery during the winter. With stock trails tyres it's too much slipping, especially the front end. So I though studding the tyres. Anyone done this on a trails bike? I see many kits around - screw-in type of studs. I guess the problem is the rear since it's tubless (albeit tube can be fit there too I reckon).

Great day today took delivery of my OSSA 2013 factory Bike has the latest capacitor easy start system installed and fired up on the 3rd kick out of the shipping crate. I got to spend about 2 1/2 hours on the bike today and so far I am liking it lots. First impression is that it is very different power and overall tighter feel than I am used to with my 2004 Sherco 2.9. It's power is very crisp and snappy yet rock steady and solid way down low. I find it much easier to control lofting the front end around and it's easier to hop over logs or anything else than with the Sherco due to the near instant throttle response. Like the no fuel petcock, no choke just fire …

Well tomorrow I'm doing a trial on a borrowed 250 mar to see how I like the bike before buying one. Already had a little play around the yard on it and was impressed on how smooth it was compared to the fantic iv been riding. The power comes in so steady with no snappy jumpy movement which also made it great to turn tightly. Hopefully the weather will turn for the best and the trial won't get cancelled. Will post how I get on and how the bike rode.

I see on the front page , the results from Bootle Scrambles club show that Stephen Dixon won on a Ossa, is this the first win for the new bike?

Its a bit quiet around here! On the advice of another forum member I've removed our flywheel covers to try and seal them a little better. Sure enough, both bikes had a little water in the bottom of them. There is no gasket but there is a lip on the lid for most of the cover except where the electrics come out. We're going to put some silicon on there to try and seal the cover up. While in there we've sprayed some innox to prevent rust. It does appear to be fairly poorly sealed. PS. Battery kit is going great on both bikes, no issues to report.

Hello, I have a gap between the cover and the casing,is this comon? I fill the casing with water when i wash the bike. I have seen both carbon and magnesium covers,any sugestions?

Does anyone out there know what size flywheel puller I need to remove the flywheel on a '72 250 MAR? From what I can roughly measure, the inside diameter of the flywheel is 26mm. Not sure about the pitch.

What after market footrests will fit my 280 ossa if any. Thank you

From the backgound of enduro and loads of oilchanges I thougt that a simple fork oilservice would be a pice of cake, but no! Read some helpful information but not realy a complete explination. So, went for the classic counted the clicks to max, back to fully release pressure at minus and then loosen the cap. (Drained the oil from the lowest bolt first). Did all the refilling and air bleeding but when mounting the cap, with the unusal rod stuck to the cap this drives the rod to bottom?!! Leaving no chance of changing the clicks? Do I have to mount cap/rod at max + so that I later can loosen the compression nut to right set of clicks? And what is the standard set of c…

Anyone tried these yet? http://www.bytoto.com/hfs/node/5 I need stiffer springs, but these may be worth a try. Mike

If anyone is interested Trick Bits are now making swingarm and frame protectors as well as Ossa number boards.
