OK, I've been doing a bit of investigating. If there are people with flat tappet bikes who fear that their bikes may not be eligible for the roller update if their flat tappet top ends fail I *May* no guarantee, be able to get a job lot discount on conversion kits that will be a LOT cheaper than the Austraian price.
I don't want to go really public on this for reasons that you can probably figure out but if you're interested? PM or email me.
