Latest I heard OSSA finally got itself loose from the Gas Gas (Torrot) situation, back to Joan Gurt hands and he's actively searching for an investor to restart the production in a smaller factory as I understand. So the good news is at least GG doesn't dictate anything currently. Another question is if OSSA finds enough funding in Spain in it's current rather lagging economy.
IMO, OSSA seems like a good if not excellent deal for any investor with even a tiny bit of a clear minded vision. OSSA brand is pretty much worked up into trails sector plus you get a niche design ideas and engineering concept to separate itself from the rest of the competition so it would provide an excellent platform to market and develop on. Hopefully someone will step up and take OSSA under it's wing so we can have new OSSA bikes again.
Hell, on a second though even I'd buy the OSSA company in a heartbeat it if I just had enough resource
GasGas is in other hands now, so you don't know if that's a good or bad thing.
Although I thought that the free spinning gear on the layshaft had too much play, it wasn't as bad as I thought.
Thanks to InMotion I got a brand new, about 40 year old shaft and gear.
Thanks to a manual, and the simple lay out of the Bultaco engine, the rebuild is coming along nicely. Crank and cylinder are expected back from the shop any day now...
It does not matter really how you do it, but what conclusion you conclude from it. Without the dipstick screwed in, and to the full mark, makes it too full. It should be around the middle. With it screwed in, the full mark will result in half of the dipstick unscrewed.
I, and I suspect most 4RT owners have done it always as the manual prescribes, without any problems:
Start the engine and let it idle for a 3 minutes.Stop the engine and wait 3 minutes. Support the motorcycle upright on a level surface.
Remove the oil filler cap/dipstick on left crankcase and wipe the oil with a clean cloth. Insert the dipstick without screwing it in, remove it and check the oil level.
Going by the volume (440cc) is inaccurate because you don't know how much oil is left in the engine after draining.
Did you do the oil change yourself? Did you let the engine run for 3 min. and then rest for 3 min. after the oil change to check the oil level? (I know this should be obvious but you never know
If engine oil somehow gets in the gearbox, which would surprise me, I suspect it's via seal n° 31 (sits between the crank case and the primary drive / gear box)
I'm still in awe at the skill these guys have, but all the videos are the same these days, always a guy hopping from one rock to another on his rear wheel.
I would like to see them do some steep ( muddy) hills for instance.
`Someone link/embed this please who knows what they are doing.[ Electric trial bike championnat de France de trial Breal]....yes its YouTube my favourite.
Just copy the address of the page and paste it directly in the reply.
The Nissin master cylinder made a noticeable difference on my 2008 4RT but haven't had the chance to test it on my 2015 Repsol because I already sold it.
That said, the one piece caliper brake on the 2015 Repsol is already a great improvement compared to previous models.
Please note that the 1 piece caliper of the 2015 Repsol has a 8 mm banjo bolt as opposed to the 10 mm banjo bolts on previous models, so you need a specific brake line. (H&D Racing sells them)
That sounds really good I have family in Brussels so I am going to try to do the trial on the 26/27 th of March do you know anything about that trial? The 30/31 July with the trial the week before in Germany sounds really good i will have to book that off work.
Aywaille one of the best classic trials in the Benelux if you ask me.
Put some neoprene fork boots on your forks and you'll never have to clean the seals + your fork oil doesn't get contaminated by the dirt that passes the seals.
Now isn't that lovely, they stamped a little hart in the case.
Cylinder and head ready for painting, which in the meantime has been done. The cylinder is at the shop for a re bore and the crank shaft for a new con rod.
I gave a drawing from the rear sprocket from my Montesa 315R to an MX dealer and he passed it on to Kit Cross, and they made one for me for the normal price of a rear sprocket.
shaft and gear.
