Fixing a stuff up on a Rotax.

[NSR]

The stuff up is leaving a 10mm nut in the air box.  The fix is a lot more complicated   The chances of getting a left side case or a motor is Zip. 
So what ideas do some of the best bike repairers around have?  Any advice is appreciated.
   




This gouge above the port will be hardest to repair.

if anyone can fix it he can
wont be cheap or fast
you just have to wait till he gets it done
he has done heaps of stuff for me and a lot of other racers as well

It's not bad really.

Given the disassembled crankcase, a competent bloke with a TIG welder and a lathe with a face plate would have that fixed in an hour or so.

Try a local light engineering business.

Like they say Shulzy it looks worse than it is ( to me it looks terrible ) but there are many clever buggers out there who would be able to fix that in a heartbeat

Thats a pain Noel. I had a chunk of piston enter the inlet port once - peeled the disc into a big curly into the crankcase! Damaged the case like yours although not as much. Cleaned it up with a file and stone and the 'revised' port timing didn't worry the bike. 
Check that the disc drive gear hasn't cracked at the key slot- it's not uncommon to happen if the disc has come to a sudden stop. Wouldn't hurt to check the flywheel key as well (although that'll happen anyway if you are splitting the cases).

Might have a set of Rotax 250cc cases TNT Can-am model with the oil pump  I think

Let me know if they will Help you ,

Some JB Weld/Liquid Steel bit of a grind then a new disc (let me know if you need a disc )

Are they an Aluminium or Mag case? Either way it quite repairable with a bit of weld they milled of.

These things always look bad but there is little that can't be welded and machined.
Its just the degree of difficulty that determines the dollars that need to be spent.
Doesn't look overly hard to me from what I can make from the photos.

Liquid metal type stuff has its place but I wouldn't rely on it for structural type stuff myself

I would be wary of going to you local small machine shop. These guys will usually be really good at machining but not that switched on with welding odd stuff so suss them out before you give them the job.

And if 'old mate' reckons he can MIG it for you then grab your case and run
