OSSA

Does anyone know the correct procedure for reducing the springiness of the front end? I am enamoured of the plushness in the Repsol 4RT and know it wont get there but can the ossa be easily softened? thoughts?

I've heard of people fitting greasing points To there rear suspension, just wondered if Anyone could take some photos of where to Stick them Jsp

Has anyone retro fitted a breather pipe up behind The kick start, like the newer bikes have ???

While riding, I washed out the front end turning up on a rock face. The bike slipped down and momentarily over revved the motor (as it has done numerous times). I pulled the clutch, picked up the bike and the bike died. I returned down slope and pop started the bike. Returning up hill I noticed the bike had a loss of power and would not idol with clutch fully engaged? Returning straight away to the garage, I noticed the bike was running a bit hot. After a cool down, I topped off the coolant with 100ml/ 3.3oz. (not sure how much it takes to fill from empty). The bike kicks through the same whether in gear or neutral and sounds/ feels like it wants to start. Any ad…

I broke my clutch lever on my Ossa. Do I need some special type of lever for it? Anyone have a favorite lever they might recommend? Tnx

Anyone know the piston to cylinder wall clearance spec? The ring end gap as well.Searched everywhere and can't find it.CVTech in Quebec needs the numbers to redo the nikasil liner.

Took clutch cover off last week to change clutch springs, and found the crank shockabsorber was past its prime. would have been noisy on sunday.

I'm pretty new to trials and fancy a newer bike. I really wanted a 4 stroke Beta but I just can't find one. I'm now looking at 2 strokes again. I've come across a 2013 TR280i but know nothing about them. I wouldn't even know how to identify it as a 2013 model? What's a good price for one of these and what should I be looking out for? Cheers!

WTF! A bolt on both sides of a pivot? How the heck are ya supposed to get these out? Last thing to remove before the frame powdercoat. Grrrrr!

So my TR280i is losing coolant and it certainly seems to be going out the exhaust. Beside the fog out of the exhaust, it also smells of coolant. I started to pull things apart and when i removed the exhaust pipe there was a trace of coolant in the pipe. When i removed the cylinder head, the o-ring still seems good. Obviously i will be replacing them, but is there anything else i should be checking before I put it back together? Thanks for any tips.

It's looking a bit ratty and I want to do a couple of things to the bike to make it more suitable to me.the frame is going to get a black powdercoat,the triples are getting black anodizing and i'll change the airbox cover for the new style vented one.I'm going to try and see if I can get a 2015 sticker set for it if it will fit the 2011 plastics.Might have to get a newer seat base and bendy rear fender.While the engine is out,another base gasket is going in to make it easier to kick thru.I doubt it will effect low end power,but I might lose top end.Never use all of it anyway.

I recently put a new clutch in my factory 300 and it works fine but the lever is spongy as Hell and it feels like crap. I've never had such a hard time bleeding something in my life. It uses mineral oil, I first filled the lower cavity with mineral oil then attached the line so there was no air below that. Next I pulled the cap off of the reservoir and pushed mineral oil with a syringe attached to the cracked bleed nipple until it was half full. This method has always worked for me first go but not now for some reason. I've tried several times now and the clutch lever feels spongy as Hell, not nearly as solid as it was or should be. The clutch engages just fine an…

Well, just learned of another delay in my Ossa Factory delivery...recall on the main bearing. I'm now on near 3 months delay. So the importer is going to have to uncrate the bikes, repair, recrate, then ship to the dealer. I'm assuming another month or so...assuming the importer gets the parts quickly. So I'm getting a model '14 bike well into the 2015 year...all at a premium price...IF there are no further delays. So... 1. Is The bike worth the wait? 2. Is Ossa healthy financially...seems there have been numerous delays at the factory? The Importer has never made promises...just given me ETA's. Yet Ossa has constantly had issues in manufacturing....not exceed…

Ok guy's, got a 250 Mar here with leaky fork seal (apparently) and bottoming out alot. On strip down the seals were immaculate with as new edges on the 'scapers' and the dust covers gripped the stanchions good. Stanchions good fit in the sliders, with clean ATF drained from them, though a minimal amount due to leakage. Just guessing here (not my bike) but looks like the oil had got past the seals and then trapped between them and the dust covers....then to the out side world. SOOoooo, would excessive compression tying down on a trailer force the oil past the seals??? or is there some other scenario which would explain how tiptop seals would leak? Any tips…

Found these pics with others from the Eicma show.

Anyone have any experience?Is it easier to start?

Hi, I am looking to get a spare rear wheel for practice but haven't seen much online. I have seen gas gas, beta, etc and was wondering if anyone knew if any of these other wheels would do the job? Thanks in advance...

Hi, heard all sorts of yays and nays about the 280. Has anyone lived with one (or two) and decided to keep with the marque ? Good and bad points , pref from owners ! Its near the top of my list. Over 50s clubman level rider.

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 know i`ve probably bored everyone by now but when I removed the tank today I noticed it had what looks like two tank stops on the top tube. I`ve never seen these before and thought it might be a clue as to who made the frame. Any info on the frame or bike would be gratefully received.
