Oops. My e-mail is [email protected] I forgot to say that I'm only looking for A couple of hundred for the motor. $100.00 for the swingarm. Sorry.

 

Don't be concerned about Dr. 2stroke being in Switzerland. I have personally done business with him and all the goods that he sold me where recieved and in the condition that he described. I will be doing business with him again.

 

The air shox have been scooped up. Thanks for all the e-mails.

 

Magnesium can be welded very easily. The key to tig welding magnesium is extreme cleanliness. Magnesium itself does not catch fire when welded properly. The dust from grindingm and sanding does.Look for a local tig welder in the phone book and they can easily weld it up for you. I did my 495 case recently and KTM's material is the best I have ever welded.

 

Sorry Jeff. It's already spoken for.

The 79 420 did indeed exist. I have a cylinder and head from one if any one needs it. I had a 1980 420 that was a fantastic bike.The problem with the old KTM big bores is getting pistons. I think the 420 is 85 mm. You can probably get something pretty close to it from wiseco. I got a 92 mm. piston from a watercraft for my 495 from them. The only draw back was pin hieght. A connecting rod from a CR500 combined with stroking it 4mm and lowering the port timing 1.5 mm. makes for a 520 that should be more than reasonably powerful. I would think that you should have better luck with the smaller piston. Good luck.

 

A injury to my neck at work forces me to offer up my 495 project. For anyone who doesn't know of it it's a 82 495. I had a new sleeve installed with a 92 mm Wiseco piston from a rotax water craft. A hot rod from a CR500 connects to the 4 mm stroked and balanced crank for a displacement of 518.5 cc. The cases are freshly powder coated and I have made a bolt on adapter to fit a hydraulic clutch. I'm into the motor for $1300.00 And it's ready to bolt together and pull stumps. I also have a 6061 T-6 hand fabbed bannana swing arm for a 79 420 or 80-81 250,420, or 495. Any one interested can get me at [email protected]. I can get pictures if needed.

I was at the salvage yard this morning and stumbled across what looks to be a 125 GS Pro. It looks exactly like the bike on pg. 20 of the May 2002 Motocross action ,although in need of restoration.I don't know if the Sachs engine or the whole bike is of interest to you Sachs guys but I thought I'd let every one know about it.Let me know if anyone is interested and I'll get more info. Frame & motor numbers etc..

 

I have a set of Fox airs available for free. E-mail me at [email protected] for details if interested.

 

I have a complete lower end for a 81 495. I am looking to swap it for a 80-81 250gearbox or a 81 495 pipe silencer and mounting bracket. If any one is interested you can get me at [email protected]

 

I have a cylinder, head, and intake manifold for a 78-80 KTM 420 free to a good home. All you need to do is pay shipping. Takes up valuable space in my laboratory.

Does anyone know if a tank from a 77 MC-5 will fit a 79 frame?
