Same motor I had in the 67 just a few changes:
1641 cc
mahle forged 87mm pistons
Stock crank and rods
Balanced and lightened flywheel
Cb Performance equalizer pulley system
Bigvalve(40mm) SP heads.
HD valve springs,solid shaft rockers,elephant feet adjusters
Scat C-35 cam
Zenith NDIX single carb with manuel choke
Not a speedster by any means but will climb any hill with ease. :lol:
Way more solid pulling motor than the 1641 with duel carbs and way easier to tune.Not to mention not as loud.
Next motor 1904 SP. :shock: I'm really hooked on this Zenith set up and I've tried many different carb setups.
This motor was born from a few conversations with The Godfather. Instead of building the 1800 I built the smaller version and will now build the big brother of the same design for the 67.
