Ow. Mine have red top 'guards' and black body. Havge I mounted them U/S down?

Nice tune FF! This may be about 24 HP then maybe 26CCV?

The head is exquisite.

Piston nice: is it Wiseco? Which one?

Shame about the intake: that is a real mess (Worse than Malossi Vespa PX)

hum! yanker 24 bhp?? I don't believe so: maybe 18. I can't imagine this old stock barrel able to give such a big load of power. Anyway we shall see later. Maybe a dyno...

begining of the boost ports. Second one will unfortunately come out in the manifold thread... Not a big deal but boring indeed...

why have you gone for that head?
isnt it designed for the rt kit which at a guess has a longer barrel to allow the spigot to sit into it
your on a std length iron barrel from what i can see...

Clean but just need to go a bit deeper cause reboring (from 66,5 to 67,5 mm) would reduce them about half a mm. Oddly I'm still away from the thread....

piston inside:
I keep the idea to get a big 3rd port by joining the both small ports. Could be a future update....
