Stiletto TT and MX
I'm curious, but what is the difference between the Ossa Stiletto MX and Ossa Stiletto TT? Were they both used to race motocross? Thanks, Jim

1977 Ossa Phantom
Ossa phantom 250
Have a 1977 phantom ossa with simmons forks and fox shocks. Has been in storage since late 70's. Bike needs to be restored and is not mint but mostly complete. Bike is not frozen. Photo's and additional information on request. Best offer
Hello again. Would you like a pic of the yankee or the ossa? I was mistaken in identifying the ossa. I thought the forks were simmons but are apparently marzoochi. I did a bit of research on the bike on the net tonight. It has yellow fork legs and fox shocks rear. Apparently it is an as77 with moates mods. I know very little about european vintage mx bike, most of my bikes are post vintage japanese mx bikes. I will take a few pics today and get those out to you. Will you adjust my post accordingly with the photo's? I was hoping on getting the bike into an enthusiasts hands who can give the old bike the attention she deserves
here is the photo of the ossa. Bike has been sitting for 30 years in a shed. it kicks over with compression but there is no carb and is missing control perches, number plate. I think it would be a good basis for a restoration.

'74 Ossa 250 Pioneer
When cranked, the engine immediately revs up to intollerable RPM's, like wide open. It is not a throttle or carb problem, as they are in good order. Please advise what would cause this.

Rode one for years. Great woods bike. Only problem was rear brake. It went away when it got wet and nothing brought it back until it totally dried out and you readjusted it. Up side of this is that you learned to turn at speed.
Presently involved with restoraion of SDR and Desert Phantom. By the way SDR was only available in 73 & 74 after that they replaced it with Super Pioneer and in 78 a special run they call the Black Six Day. Have fun and good luck

I would like to confirm which adjustment screw is which on my 1971 OSSA Pioneer. On the right-hand side of the carb there is an adjustment screw on the rear towards the air filter and another on the front towards the cylinder. I suspect one is low speed and the other is high speed. Which is which?
Also, how does one adjust the idle speed on this bike?
Thanks for any information you can provide.
