How often are they going?

I cant find anything on if the 139QMB stuff will work on a KG10SA engine which is what is in my RS 4T. 

The Chinese 139QMB and the Taiwan KG10SA are interchangeable engines, except for one mud-guard trim fitting.  I replaced my KG10SA with a mail-order 139QMB a few years ago, added a BBK and cam, adapted a mail-order exhaust, and it's still running fine.  The exhaust can be a fiddle since the fittings may not line up.  This is normal - take it to a local muffler shop for adjustment.

Thanks for that info, Its great to know. When my engine finally gives up the ghost, I know what I can replace it with now  
I got the Stage6 exhaust in the end, It fits nicely, Looks like it was supposed to be there standard. Removeable/reinstallable baffle is nice to have too.
