Imagination and money. Check your rule book. This one isn't legal.

Now that's what I'm talking about! Nice.
 I have a set of 34's for a VW that I was going to use...not as pretty as those.
 For all you flat head guys an FYI... The pistons used in oppy's and singles cylinders are exactly the same size as stock air cooled VW's
I'll try and post a pic.
Sorry pix won't load... 3 3/8" = 85.5mm
Pic was of both pistons.

The two stock piston sizes for an oppy and a model 28 and 31 respectively are 3.4375(3 7/16") and 3.5625(3 9/16), not 3 3/8"

Legal under FXS.
That engine should also have external hole drilled and tapped for upper cam and crank lubrication so as to use solid core camshaft. Those are Mikuni 34-2 flat slide carbs.

Any ideas on who it was that made the adapters?
Old oppy's never die, they just go faster!
