    2020 was a ‘nothing year’ and most people would like to not remember it. I found that I actually spent more money than I thought I could......... pictures to prove. Follow my gripper story #ossa_gripper on Instagram what did you spend ...

  2. My weight is 122 lb, sometime I have trouble kick starting my Ossa Explorer...the kick start do not give enough leverage..too short and slippery. Has anybody know replacement kick start from other bike or custom manufacturer that is has longer arm ?..and fit the Ossa kick start stub ?

  3. Started by sclay,

    Hey mods, can delete if not allowed. As Lotus54 knows, I recently cooked my Explorer ECU through pin 3. No damage to the harness, the plug is cooked, but that can be replaced. So I'm wondering, as I hunt around for options, if anyone, anywhere, has a known working ECU (or 2) they are willing to sell. It is the 520030211 unit, but I'll take whatever ya got at this point. My only other option(s) at this point is to sell the bike for parts (not what I'd like), or to install a standalone ECU, which, if I can't find a factory unit, is the route I'll likely go down. Post in the thread or send me a message on here if ya have anything! Cheers!

    Hi guys as title says really, looking to buy a 2011 280i and was wondering if there's anything I need to look out for specifically other than the normal stuff. Really need the help as I'm tossed up between the Ossa and a late gold frame Raga, so peoples opinions on that too would be welcome. Cheers in advance fella's.

    I haven't attempted to remove it yet, but my kick-start is loose, ie. It doesn't stay in the folded position to keep it out of the way during riding. Is there a warn part I can replace / build back up with weld? Or is it a case of throw it away and completely replace?

    Hi, just changed the clutch springs in my MAR for new ones and now the kickstart doesn't turn the engine, and there is a nasty spring recoil noise,seems to be return spring noise, have checked that there is plenty of free play in cable and that the new springs are tensioned up enough, any ideas, am going to refit original springs but seems like the rachet is no longer engaging. would rather not have to split cases. Thanks for any advise

    2015 TR300i Recently purchased this bike and had a hard time starting it. Fuel pump was suspect and was the problem. After replacement the bike fired up and ran perfectly for 10 minutes - until it stopped. No spark, tried different plugs - nothing. Do these bikes have a weakness in the spark creation department ? Anything come to mind after an engine removal but ran for 10 min after install ? Not enough time with this bike to know what the go-to's are. Everything seems to be plugged in and secure. Pulled a coil off another dirt bike but still no spark. Blue/black wire to coil does show a voltage signal on a digital meter when moving the kick starter.

    I need to pull the magneto flywheel off on a '72 250 MAR. Probably a silly question, but which direction do I turn the flywheel nut? Clockwise or counterclockwise.

    I can't seem to find the info, so thought I'd ask. 2014 Factory 300. There are two maps- 1 and 2. What do the two positions do? Which is 'soft' and 'hard'? I see on some other maps they list which is which (or 'hard' and 'Road' etc), but the Factory one does not. Thanks Mark

    My '74 Mar is really, really difficult to start from cold. Lots of kicking, plug heating and tickling it eventually fires and runs. There's no 'almost starting' - the penultimate kick is no different from the previous 20 (or 30). When it's warm it runs and ticks over fine and will re-start first time but leave it a few hours, let alone days, I'm back thinking of selling ! Current plug is an NGK BP5ES Any ideas ?

    I have just found out that where I thought I had a 250 MAR, it is in fact a 350. Last year I brought a new Minuki carb for the bike but spec'ed for a 250. What jets and setting should I change too?? i have noticed the bike has a low down flat spot , so hopefully this is the reason why?!

    Could anyone give me any ideas where I can get spares for my bike. Currently nothing in particular, but seem to struggle to find bits.

  15. Started by markwemple,

    Recently purchased a 73 MAR and a 72 Pioneer. Will need help refurbishing them. I'd say restoration but neither bike will be brought back to completely original. I'd appreciate contacts to used parts, any pics of authentic bikes, owners manuals and so on. Any and all help greatly appreciated. Tried attaching pics with no luck

    Hi, got a nice MAR here, gears on right. I can see that the swap of the gear lever is simple. Any parts needed to put brake on right? Also appears to have two neutrals, one between 3 and 4 as well??? Many thanks

    Bit of a stupid question, but when you put the nut securing wire on the mar clutch, do you route the wire through all 5 posts or wire them individually
