    Are there any Ossa Enduro owners out there. I just picked up a 1972 Ossa Pioneer today. Owner had replaced tires, sprockets and chain. It runs but needs a little work before it is ridden. As I go through the bike I was looking for a good forum to ask questions on.

    I still have the 1972 Pioneer I bought new - at one time I had 14 Ossa motorcycles. They were a great bike in their time with amazing low end grunt for a two-stroke - perfect for the tight woods riding common on North Georgia.

    A trade was involved but I would say value of the trade was about 1500.00. Which with the tires, chain, sprockets wheel bearings and some other items that were done was a good thing. I plan on riding it a bit and then sell it and try to get my value back.

    No wonder they were hard to find you owned them all.

    I owned a 70 Pioneer that I brought back to life - sold it to a guy in Australia.
    I've owned quite a umber of OSSAs- raced Phantoms back in the 70's
    Great bike!

    There is a mailing list with some very knowledgable people on it.

    I have a 2014 OSSA now- fantastic bike!

    Is is the replacement for the Pioneer- still in concept stage and with the Spanish economy who know if/when they will build it

    New Explorer? weight, fuel tank capacity, range? - I like that a lot - looks like an outstanding playbike. The old Explorer was a MAR Plonker with a bigger tank and plusher seat - really miss my old MAR it was the most fun of any bike I've owned.

    Yes, new Explorer.
    2 gallons, I've gone over 60 miles of Singletrack without running out of fuel.
    163lbs dry. I weighed it, with both bikes 3/4 tank fuel, it was 75 lb less than my 09 KTM 300 XCW!
    Yes, this new one is the same idea, the TR trials model, with extra fuel tank and subframe/seat (plus full lighting)

    What does a new explorer set you back? I can't believe how much weight they have taken off these bikes since I quit riding enduros in the 80's. I was at Mid Ohio Vintage days last week and have to say it took me back 30 some years, and to compare the vintage to the current is something else.

    It. Was about. $8k.
    Not cheap, but about the going rate. I sold my RS250 and GasGas TXT Pro and that pretty well paid for it.
    Plus I've sold my KTM since I never rode it anymore.

    I am just getting ready to start the Pioneer that I bought a few days ago. I did notice that the fellow had left the one petcock turned on and gas was dripping out of it. When I kick it over with the plug out it will push some fuel out of the plug hole. In my old days of riding enduros if I would ingest water or crankcase would get flooded with fuel real bad I would take the tank off and actually turn the bike upside down on the handle bars and rear fender take the plug out and kick it over and then just let it drain for a bit. Does that solution still hold true for a OSSA?

    I would kick/push it in normal attitude, then flip it over, put it in gear and spin the wheel till your arm falls off.
    Be careful with those fuel petcocks- they get old and quite brittle. New ones are avaliable and I would plan on buying a pair and new hose.

    If the clutch is stuck (common) I would tie the clutch lever to the bar- let it sit over night. With it still pulled in, start it, push the bike to slide into gear then
    Stomp on the brakes. That will usually loosen it right up.

    Thanks for the info. I did tip it upside down and put in gear and rolled the wheel it probably pumped out about a 1/2 pint of fuel that was in the crankcase. Turned it back over cleaned the plug hooked everything back up and 1 kick it started right up. Now that I have it running I am going to check lights and output from magneto. does anyone know of a 12 volt conversion for a Ossa Pioneer.

    Well, the threadjacking's already occurred, so I'll continue it.

    Here are my MAR and Explorer, both made in mid-1974. The MAR did well in its day - 2nd in the national trials champs in my country. The Explorer is a better trail bike, just acause of the tank and seat.

    Both have period Mudder mudguards ("fenders" for the Philistines among us...), the MAR's rear shock top mounts are moved forward, but otherwise pretty much standard. The Explorer still has a standard speedo that works.

    I just love these things offroad: running out of steam? running out of grip? - change up a gear and nail them.

    I lust after a '74 SDR. None came in to New Zealand, as far as I am aware. Bugger all of any OSSAs did...3 Explorers, a few more MARs.

    Hey PJay, nice looking bikes. I am going to change out the crankcase oil and get some fresh fuel in the tank for the new purchase. I have been away from 2 strokes for awhile (35 years). What is a popular oil for the gearbox and what is a popular oil to mix with the fuel and what is the ratio you guys use for the fuel oil mix. Just got back from Michigan SOS trying to get a title as the bike had none. Purchased the bike out of state which made it more difficult, anyone interested in what I had to do, post the question or send me a PM. Thanks for the help with the oils.

    I have a MAR and a YankeeZ.

    Ricky Stator will have a Regulator that will allow you to use 12volt bulbs.

    You should replace the cranks seals, other wise it may run lean and stick the motor.

    Down here, we tend to run ATF in the gearboxes of the old OSSAs. I use old racegas from my TZ Yamahas, which is basically Avgas with Castrol 747 race 2-stroke oil at 33:1.

    But at least on these plonking-type OSSAs, I'll happily run low octane fresh pump gas and modern 2-stroke synthetic of any known brand at 40 or 50:1. I just use the old racegas to avoid having to dump it.

    On a shop manual I uploaded it mentions a battery in the ignition system. Has anyone ever run one. I have a old BMW airhead that is 6 volt with a magneto start and the battery is just for the lights so I use a small 6 volt battery from a emergency light system and it works quite well. I am in the midst of checking all electrical on the pioneer as it starts and runs but none of the lights or kill switch or horn work. I like to get familiar with my new old bikes before I get too far back in the woods.
