I'm in Victoria, Australia and need to know where I can get replacement parts like conrods, cylinder/piston assy, main bearings etc

Nearly time to do the first rod and would like to get piston/liner and main bearings etc while I'm gettin the rod for later

Love the .12ZX and so does the 733

Glad to see you had much success with this engine. I got one when it first came out and I was amazed at how stupidly fast it was. Mine is in my Mugen MTX4 and most of the time run like a scalded dog at temps between 195 and 220. Mine has only been above that temp five times due to my car either being stuck in second gear of stripping out second and only running first gear during a qualifier.

Thumbs up OS Speedm 12XZ another great weekend

The engine was definitely fast this weekend no issues at all.It powered my KM HK1 to 5th place finish in the A-main this weekend at our SoarGrapes race here at our Fort Meyers track home of the Winternats.

Default Speed XZ vs Speed XZ Spec2 differences.

Hi,

I see the 'Spec2' version of the XZ has a different P/N for the Head button, crank and the crankcase, just wondering what changes were made to these parts compared to the 'XZ Speed'?

Looks like the 'XZ Speed' was only on the market for 5 or 6 months before the revision, why? Was it a runtime or power thing?

Cheers

Default exhaust?

hi can anyone tell me if an exhaust and header made by novarossi for a 12 engine will fit the 12xz and the tg looking to run in both touring and pro later, are the exhausts and headers interchangable between brands. if so could you please recomend a set. the novarossi sets seem cheap if they fit. thanks for any help mike.
