Head scratching at it’s best.

Followed Johnny’s advice and let it rest for a week + it was too cold to work. SOOOO drumrolll…

Carbs cleaned and I tell ya they’re clean

Iggy set up pedantically

All carb to jugs seal bettered wiv a dab of silicone… everything is air and oil tight.
Heads retorqued.
Changed the petcock, it flows well
Everything as per std specs.

Still revs at about 5k. MAkes you feel like you wnat to shut the throttle, but.. slides are as low as possible. It also doesn’t cut th revs when you rev it up… goes slowly back to 5k… so throttle response NOT snappy.

MY plugs are a nice darkish milk choc color.
Except the LH one : has the same color but has a side of the porcelain where the color is still white original.

Could this indicate an air leak?

I pulled the rotor off and check if the bloody seals were the right way in… they are! I’ll just shoot you a drawing of a detail that I’m not 100% sure about it but it looks OK though and couldn’t cause the rising revs prob.

kinda disappointed here.. it would have been a good ending

Boy in 15 years of dabbling with bikes and scoots, I’ve never had something that obstrusive. Makes me really question my practice

So if the crank seals are allright, then it boils back to the carbs doesn’t it?

Could the heads play tricks like that? say the plug hole .. I think I’d hear something, though…
