Ossa TR 280i hard to start

Featured Replies

I have just become the owner of a new Ossa 280. I have coveted this bike for many months and its finally a reality.

But I just cannot start it. Others have. But I seem unable to find the trick to it.

Can anyone help me. My soles are bruised and battered and the bike sits looking like a bitchy virgin on her wedding night.

Help me.

    I would agree with Borus here, I had some starting issues when running map 12 which were rectified by applying map 13, I also got a nice quicker tickover from 13 as well. The odd occasion that my bike

  • did your dealer set your tick over at 1400 rpm and tps at .6v after loading map 13? this is a new procedure, should only have to be done once, sorry to tell you but your starting issues are not normal

  • It's not user adjustable, your dealer sets both the idle and tps with the diagnostic program. 1400 rpm is a good healthy idle, (you will see) anything less on map 13 and you will have trouble starting

Sorry that I have no advice to offer, but I love your comparison!!!

Gotta be something wrong with it surely??

Is a 2011 or 2012 bike?

Please keep us updated on your progress.

Best of balance.

First thing I was told when I had my first ride on 1 earlier this year was to leave the throttle alone, take your hand off the bars next time & see what happens. Ask Peter if he agrees that this helps,it was Kevin down here in the Manawatu that told me that trick

The fuel injection apppears to not like getting signals that the throttle is open while being kicked over, bikes with electric starts hide this because the motor keeps spinning over longer, I'm not sure what the latest model injected mx bikes are like to start but imagine they would be similar

As the last post says don't touch the throttle and try and set the engine by nudging the kickstart so that you can get the maximum leverage against the engine compression. There is a bit of a knack in the kick too I think it should be hard enough to turn the engine but not so hard that the engine does not spin because of some slippage in the mechanism. In this respect it seems to me similar to some Gassers. Finally I suggest standing up on the footrests while kicking it over. Sounds like you can lean it against the bridal bed! They are lovely when they go and the injection is so smooth off the bottom I nearly fell off it the first time as I expected the usual torque shove from the engine you get with a big Sherco or Gasser.

I have an Ossa and there is a knack to starting. If you try to start it twisting the throttle it will not start, a couple of strong prods while you do not touch the throttle at all will set the fuel injection,then take up the slack (1/16") on the throttle and it will go. Even from new it has always starts in 4 to 5 max, now 6 months on its 2to 3.

Ok getting a bit better at it now.

I was astonished that the kick start whacked into the foot peg, but by following the above advice, from Peter B

and wearing boots and standing on the pegs the angle seems better.

It is getting easier as it loosens up and it is just a dream to ride.

It is everything I ever wanted a trials bike to be. Light tractable, quick, smooth, responsive and did I mention light?

Absolutely loving it.

Wish I could change my login name to Ossatic though!

what did you have before?

I have found the bike usually is a 3 or 4 kick affair from cold, no throttle but as soon as it fires give it a quick twist. Always start the bike in neutral and have it leaning supported by the bar end on the wall. This will give you a chance to stand high on the left peg for a solid prod. Once warm find it very easy with a single solid kick. Trying to kick it or any bike over without boots will give you more trouble than even finding a virgin nowadays I think.

talk to your local ossa dealer, your is 2011 or 2012

the below msg is I got from OSSA local distributor

About the problem that you have starting the 2012 model. It is due the high ratio of compression that the engine has. Depending on the humidity and temperature you will start the bike easier.

Our engineering department has improved one of the parts of the motorbike. They will introduce these modifications in few month.

Then you will be able to start the bike with your hand!

On a high compression 2stroke This sounds too good to be true :rolleyes: .... Can you please give us some clue as to how this will be done?
