General Discussion / Ossa still in business?
« Last post by Westoid Ho on May 20, 2017, 10:43:22 AM »
Hello all,
Been trying to find out what the latest state of play is with the ossa factory. Are they really completely out of business now? I bought a 2013 tr280i brand new. No bother at all with it so far, but I can't afford to stock up on s spares for the future....

Hello back from the Highlands of Scotland! I bought a tr280i brand new in 2013. No competing in competitions or the like, just hitting all the local mountains with my mates. Love this bike. Hasn't missed a beat since I got it...

Yes, the master cylinder is a bit difficult to bleed.
  Watch the videos a few times and try it.

I had sort of a system now- and also got a spare master cover that I will install a fitting to pressure bleed. I think that will be better.

Where are you located?

I installed A Clake 2 on my 2016 beta crosstrainer. I kept the rear brake pedal.  I have tried for six months to get the rear brake system bled properly. Any suggestions? Sometimes it pumps up a bit after i ride for awhile but if the bike sits it goes flat.

Explorer / reed valve intake system
« Last post by gianni schena on August 01, 2016, 11:23:16 AM »

I could not find on the manual or other literature who is the maker of the reed valve intake system of the Ossa.

there are two makes around : A) Boyesen Carbon Tech and B) V-Force.

Interesting to know if you have tested both and what you think of them

thank you for your attention , gianni

TR280i / Re: 2011 tr280 i wont start

I'm thinking the 9v won't power the fuel pump.

  If I have a suspected issue, I'll run 12v in the appropriate  diagnostics port, then you can hear the fuel pump prime.

If it runs out of fuel it is a bear to start without priming. (At least for me)

Explorer / fuel Filter
« Last post by Lotus54 on March 25, 2016, 06:14:50 PM »
A week or so ago I popped the computer onto the bike ( someone else wanted a 'How to)
  I saw a 'high current to fuel pump'

Well, I used to check fuel filters on my old Ducatis by measuring the fuel pump pressure- current goes up means the filter is starting to get clogged.

The filter is not available separately- so since I plan on keeping this bike a long time I bought the whole pump assembly.
  I believe it is the same setup used on a few of the KTM models (pics and filter are the same)

The filter is a Mahle KL 97
  It uses the crimp style  full circle clamps.

Unfortunately, the engine must come out to change.
 But I have some 280 hours so it would be good to really check everything anyway.
(Bike still runs great)

I'll replace the filter (and maybe pump) on my original setup and have it for a spare.
OR just fix up the original and keep the new one as spare.

I'll post up some pics.

I did buy a tool from NAPA auto parts to remove the connectors, I slight modification and it worked great. About $8
