GTM Monster Builds

Unbelievable, awesome and beautiful. Todd, does it make sense to use the California engine as a basis for a build or just the 8V?

Grazie. I can use the Cal 1400 motor (which is a 8V), but it's the gearbox and swing-arm/CARC drive/all related that is critical to these builds.
 
" I can use the Cal 1400 motor (which is a 8V)..."

Ha ha, I would have gotten a big surprise pulling the valve covers to adjust. (I don't know why I was thinking it's 4V). Anyway I've often looked at the beautiful engine/drivetrain on my Eldorado and imagined what a really stripped-down, minimalist version of the bike would be like. Your builds are similar to what I see in my mind's eye, so I was wondering.

8V in Italia-speak is Quattrovalvole, or 4-valves per cylinder (8-Valves in total - don't ask I say). Your 1400 is the same as the 1200 (1151cc) 4V (x2 = 8V) motors. I agree on your thoughts/vision. Imagine your motor in a 400 lb machine. That is essentially GTM-01, but with cams and enlarged twin throttle bodies. Any "CARC Guzzi" 1100 or 1200-2V, or any 1200-4V (8V) will work as a donor.
 
I should have said, I thought my 1400 was 2 vales per cylinder for some reason. Anyway, point taken on CARC. It's a nice looking system but I haven't experienced it yet. Almost bought a Griso, but alas. But your bikes take it to a new level. Even 100 hp in a 400 lb package would work for me :)
 
I am glad to see things going well for you and your custom Guzzi's. That is a cool article on your stuff.
Maybe one day I will be able to afford one of your bikes. In the mean time, the shock showed up yesterday and it looks great. The box took a beating in transit, but the shock made it undamaged. Sadly, the Griso is off in a corner waiting for me to replace the clutch. But I look forward to getting it back on the road to enjoy the new shock.
 
For those asking how my 1380 motor makes so much more power than the C14, this is the intake manifold off the single throttle body 1400 motor below vs. the 1200 twin throttle body manifold at the bottom. Add cams and a higher redline and they make big power.
