TR280i / Re: 2012 280i just started running pooly

Through dumb luck and persistence I got it running but I would still like the diagnostic cable if anyone wants to get rid of one.

TR280i / 2012 280i just started running pooly
« Last post by phildirt on December 14, 2017, 11:04:53 PM »
I've enjoyed my 2012 280i since new but recently it suddenly started running extremely poorly and I barely made it back to the pits. Now it won't start. It will occasionally fire but not stay running

Assuming it was a fouled plug, I checked spark. Looks excellent. Yes, it's got a 1/2 tank of good fuel.

I have attached 12V to the fuel pump and the fuel pump runs just fine. I've attached 12v to where the large capacitor attaches to the harness and it does not help the engine start.

Any thoughts?

Is the diagnostic tool still available and does it work?

TR280i / Re: Transmission Fluid

Be aware the oil also lubricates the main bearing.  Most 2-strokes do not do this, although I heard some other trials engines do.

 I have almost 400 hours on my Explorer.  Finally going to pull the head/cylinder and see how the piston is doing. lat I checked (head only) cylinder looked like new and what I could see of piston through exhaust looked really good.

Currently not producing any motorycles.
  They are attempting to start producing again- but who knows if that will ever happen.

They are making electric Bicycles now.

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...

Explorer / Re: 2012 OSSA Explorer for sale $5700
« Last post by SidFer on May 06, 2017, 05:43:50 AM »
5700 Canadian dollars for my Explorer. It's in very good condition about 25 hours on it. It comes with the https://connectthecircuit.org/2-week-diet-review-and-results 2 Week Diet Marchocci suspension, every thing else is stock. It's missing the front brake lever brake light cable. This hasn't been replaced when broken because it's not street legal in British Columbia.

Nice bike. Do you still have 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.
