OSSA

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!

Got a bit of a weep from the braketech clutch master Cylinder, it's coming from the piston rubber. Is there any thing I can try before I spend £50 on A seal kit

Has anyone fitted a tank breather to an OSSA TR80 cap? Thoughts and details appreciated.

So I got the Btwice flyweel kit and started to fit it but stumbled on two issues: 1) while nice kit there are no fixing bolts included (kit only comes with the weight and the cranckase extender shim) 2) Original gear shifter doesn't fit with extended crankcase size (it's against the magneto door and you can only shift downwards, upward's it's stuck against the door) How did you overcome those two issues: What bolts did you use to fix the weight on magneto w/o it going out of balance? Did you have to remove the magneto to fix it (manual states some special tool needed for this, can it be done without the special tool?) …

anyone managed to get a set of these diagnostic leads from Btwice yet? an if so, how are they, do they work as planned? Also, anyone have one of the Btwice adjustable throttle bodies, same question, how are they and do they work as planned?

Anyone tried one or have any information on how good or not they are? and also how much they are? I like the idea of having idle adjustgment without the need for leads or the software, or having to take it to the dealer, but of course it will all depend on the cost!

Not sure if this has been posted up here, as I ain't seen it, but seems Sergio has mave it over to the factory and got some nice pic's and some videro up on his site. I was goin to comment on a few the pics, but I see he has them coptrighted and such, and you just need to see them all anyways. I see a lot of really cool stuff there. Seems they are doing a top job on things. The design is radical by most standards, but at the same time, I likee a lot of things about it, and as an old Ossa fan, well, It does make one a bit proud that they are doing it! If nothing else,it is just friggin cool! Ck this out!

Bump stop is trashed on 280i Ohlins, does anyone know where i can get one from? get it sorted? the shock on later models seem a solid black rubber one? this one seems tan colour and softer? Can we put new one on without stripping shock ?

I have a 72 OSSA MAR. I just got it and it ran pretty good. I knew I was going to slosh the gas tank but thought I could run it a bit before the slosh came in the mail, etc. In short, I ran it one weekend and the throttle was sticking pretty bad so I knew it was time. I sloshed the tank with Caswell epoxy coating and while the slosh was setting up (total bike sat was two weeks) I cleaned the carb which had lots of fiberglass goo but is now spotless. Also the plug had a thin fiberglass film baked on. Now new plug, clean carb and it won't even cough. Before it at least tried to start first kick. Do you think that goo is causing some problem with the rings or what. …

I have loosened everything and cannot get the axle out of the forks, anyone else had an issue with this? Is there some trick Im missing?

Having a little trouble identifying this ossa, I`ve seen some pics of other canti-lever bikes but none have the bend in the seat stay above the brake cable stop. I`ts obviously recently had some restoration work and I`m hoping to find out who did the work and hopefully trace its history. I bought it in Leeds and the seats been recovered by dlc so guess its a local bike. I`ve added some pics and with any luck someone might recognise the bike and help with leads. I guess it would have been registered for road use at some point and I`d like to to trace its reg through previous owners etc. i know its a rare bike so would think someone must have seen it about and I`d be grat…

Hello here again. This spring is there a specific way of getting these things to fit. I have been trying now for an hour and all i have managed to do is end up with two fingers with plasters on as this spring has managed to cut both. Every time i try to force the spring round to get the straight part of this spring into the slot of the swing arm it just will not go in because the spring is too big to move into the round machined recess. I thought that when i force the flat part of this spring round that the spring would become smaller allowing it to fit in but it actually gets bigger??? Now this spring is new and presume that there is only one type made but i recall tha…

I am having trouble getting the tensioner spring back in. Any tips before I go postal would be much appreciated?

I want to reduce the size of the spread to the grips and levers. As this is really tiring on a full days riding. The system is AJP anyone know who makes an Ossa green AJP short lever for clutch and brake? Scorpatic

just fitting new clutch plates to my 350 gripper and noticed that the clutch basket could be moved from side to side , I,ve changed the needle roller bearing but the problem is still there , the bearing sleeve looks alright and is tight on the shaft , anybody know if there is supposed to be any movement in the basket at all ? Thanks Bertie

Anyone know where I can find one of these clutch case breathers from in the uk or North America? http://trialparts-shop.de/produkt/ossa-motorentlueftung/

My uncle has a 2011 ossa 280, the clutch is very heavy and really spoils the bike, i previously had the same year bike and mine was lovely and light, same as other bikes. Is there a way of lightening it, maybe removing a couple of springs?

I use F type atf in the gear box, but every year my clutch gets very stuck. Any ideas for getting it unstuck right now and keeping it from sticking each winter would be greatly appreciated. Thanks

Hi, Im running an Ossa 2011 with an update clutch (internals) to 2012 specs. First of all I love the bike - it is amazing in every aspect except for the clutch engagement in my opinion. To me it seems the clutch is engaging at different positions ( a millimeter or two in or out) this occurs the first time used after heavy use ie revving and shooting off. One could say it bites slightly better after a hard use. Bike has less than 20 hrs on it - will it get better or should I consider bleeding the system, changing the clutch lever oil reservoir to a bigger size? Or just plainly used it hard to see if it beds in better? Thanks in advance, K.
