I spent 2.5 hours driving a P1k-5 around in circles, slow, 2 footing crawling over rocks and freeking rail road ties this afternoon.
Used the clutch like a torque converter - its a wet clutch so it should be able to do that all day long if its designed right.
Watch this vidio, explains it better than ever could:
P1000 - Weak clutches?
I don't think there is any difference in how it 'feels' with the clutch update.
But it seams to work like I think it should (so far).
As for the cabin heat "fix" I froze my ass off, it was 35 degrees out and no windshield.
Hondas' smokin the good stuff to release that going in to winter.
It's probably a plot to make me break down and get a windshield
