Thanks TSF....alward the taper on the KTM is very steep at the rear of the flywheel then changes angle....even if you could get the flywheel to direct fit without any type of hub mod it would still need to be packed out the correct distance to allow the bendix drive to make contact with the ring gear....therefore needing a hub mod anyway ...hope that makes sense
ylwgtr:
you can see the first angle on this pic

can also be seen on the ktm crank...unfortunatly no easy way out here.....lining the KX500 hub,ktm flywheel (with crank angle ref tab) and the engine relative to ? degrees to TDC is going to be fun as the pulse pickup is bolted to the engine cover....I will need to get my mates ktm300 back and find out what degrees before TDC the leading edge of the ref tab passes the sensor (which i will have to make a mark on the crank case itself as mentioned you cant actually see its position when youve removed the cover)

Ok...back into old mates ktm300...the pick up see's the leading edge of the ref tab at 30 degrees BTDC and the trailing edge is TDC.....what generally happens here is during crank/kick starting the CDI will read from the trailing edge and once running it will read from the leading edge....the trailing edge turns out to be located directly in the center of the wiring grommet which makes my job easy...so I will park the kx engine at TDC line up the tab with the grommet hole and put the ktm flywheel on the kx hub

Doesnt get much easyer than that
