I don't know if anyones asked but was the onset of the issue sudden or progressive? Sudden would point towards electrics (the Bosch CDI's weren't startling). The stators were generally OK. Multimeter checks won't always show up a fault. Send the lot off to be checked dynamically by a professional -  including the kill button -  it'll be cheaper than shotgun solutions to imagined repairs. Particularly if someones already monstered the electrics.
 Progressive deterioration leads down a whole different fault tree analysis.

As Canam asks, did you buy it like this, did it behave this way after a rebuild or did it gradually/suddenly start behaving badly.

If your a bit suss about the electrics then send the whole kit and kaboodle off to someone that can run the whole package and test it. There are a few business's that offer this service.

Don't know much about the Rotax motors, is it possible the rotory disc is in the wrong position or that some one has trimmed it too much or maybe it's a Trials disc??

Thanks all,

I brought the bike not going had a spun key way I was hopeing that this was the problem.

I Got a new piston and did the re bore also put in new crank seals.

I think the next thing to do is to get the electrics checked, does any body know who can do this?

Thanks again for all the help.

chris.

Thanks all,

Finally got the tf1 to rev out the following items changed.
Disc valve replaced with original swm it had a modified disc installed.
Crank seals replaced.
Replaced stator original one was tested and was braking down at higher revs .
Carby jeted correctly.
Just have to work on the carby a little ,the float height must be wrong as it seems to run out of fuel and works when the choke is on.

Thanks for all the advice especially Lozza a wealth of information.

Thanks Chris.

Hamster, the TF1 looks just like a Can-Am Bombadier engine.  Not sure where you live, but find your local Can-Am enthusiast, and borrow their stator assembly- i.e the RHS crankcase cover with the ignition bolted inside it.
Let me know if you're in NSW and I can probably help.
Cheers,
Nitram

Hi all,
Well I have tried every thing to get the carb to run with out the choke,
It starts first kick runs fine and revs out for30 sec than runs out of fuel (sounds like)and when the choke is flipped back on runs fine again and revs ,have tried the following.
Doubled checked float height,lager fuel hose,checked fuel tap,removed tank cap,changed needle and seat for new,cleaned carby 16 times.
In conclusion I will be having a dellorto burning at the stroke of midnight .
Does any body know the mikuni carb set up for a swm tf1 250.

Thank chris.
