Casing Disaster

[nellyboyo]

Anybody else has this happen ???
And any idea why ??
I did have the engine apart to replace the rear hub bearing and seal a couple of days ago but it kicked over fine . Then yesterday this ???

[RICSPEED]

this is why the later cases had the ribs in this area ...you dont say if you had high comp head ,kit barrel ctc

[nellyboyo]

Yes I do, its a long stroke mugello with a reed valve . Not sure what the comp ratio is but it is a monster to kick over. So thats just progessive stress failure is it ???

[RICSPEED]

yes ...as i said it was why later casings were modified

[nellyboyo]

OK , Cheers .
Its a series 3 block with a S2 side casing in my Series 2 .
Am I right in thinking I`ll have problems with the kickstart hitting the floor if I put a Series 3 casing on it ?

[fred]

no,just fit later sidecasing,with s2 kickstart lever

[nellyboyo]

Cheers for all the help lads

That's fine. But you do realise the kickstart won't then stop against the casing. So you'll either have to lengthen the tongue or use a later S3 kickstart and bend it to suit.

[RICSPEED]

lengthen the tongue.

do what he said

Has anyone else notticed the "3" on the casing?
