Sidecar MX pics - Post them up here

I have always seen these motors referred to as 1000cc, A quick measure down the plug hole and across the bores through the ports says it's about 940cc and the other motor checks out much the same.
I have heard that the later air cooled engine with the kick start was closer to the 1000cc, perhaps just a bigger bore size.
Hopefully the little 940 should have enough grunt...

Walter may also be able to confirm theat there was a couple of different piston/con rod combinations used. At least one of my engines has EML brand rods in it with Mahle pistons 86.4mm.

And WTF is that clutch out of? An auto trans of some sort with the sprag in the back for starter engagement.

Well done Matt . That should turn some heads . A 1984 Jumbo EML . That should handle better than the 85 Mono and looks much better in my opinion . Make sure you get those brakes and arms  up to scratch first, before you ride it  .

Sorry to question the wise ones but after all the reasearch we have been doing and went back over the World championships for EML it was like this wasnt it
Emil Bollhalder / Kar Buser - Yamaha- EML - 1982-83 twin shock
Hansi Bachtold / Fritz Fub - EML/Jumbo - EML 1984-87 mono shock

82-83 are very similar to '84 frame, only a few minor differences. The very last of the '84 twins hocks came out with twin tube girder style forks

Here ya go Shelpi!
A nice lightweight 2 stroke! 

Hey Matt, hope you keep us in the loop with pics during the resto, I must say its a beautiful peice of kit, and I am very Jelous

Thanks Walter, it needs a new trenching implement on the rear, the one that is on it is shredded! not sure what I will do with the rear yet, 18" is the easy way out but not good for an original restoration. it has the steel hub (complete with broken spokes) from an earlier model so that would have to be replaced to keep it original

Cheers

Yep will do Shelpi, won't be much progress on this one for a little while unfortunately, I'm in the middle of moving house (interstate, again) and not having anywhere to store it, so in the mean time it stays in Dads shed. Besides, I still have other unfinished projects! Here is the new donk for the other '84 EML

If its steel , the wheel  must be around78- 80 . 82> they where Alu . I still have lots of spokes for the steel hubs too .

There is also a front swing arm and brake caliper off an earlier model in the box of spares. The guy I bought it off has a beautiful '80 EML YAM with an allu rear hub...
Other than the wheel, it's all there and complete dome to every last nut, bolt and washer. And the front guard may not be original.....

Doesn't matter , you still done very well .  By the way the Yam looks good too . No Kroeber ignition ?

No Kroeber yet, I can't make sence of how to adapt one to 270°.
That old advance mechanism housing is only there for decoration, the trigger mechanism for the probe ignition is on the other side. When I get a chance I will make a blanking plate instead of that housing and it's leaky seal
