Looking for a little insight. Just hit 2000 miles on the Imp. 875 Sport with a single Weber, re-shimmed and re-torqued at around 1000 miles. Head gasket is composite with red rings around the cylinders, not sure of brand.
It's been running great.. Yesterday it started running rough, stalled at two stops and barely wants to idle. Revs up sounding like a Subaru, must be running on 3 cylinders but luckily I was close to home.
I verified fuel and spark. No evidence of a vacuum leak. Couldn't spot any bubbles in the radiator top tank. Plugs looked ok. Pulled the Home wire and nothing changed. Pulling 2,3,4 and it stalls. So I'm thinking cylinder 1.
Compression test 150 185 185 175, so Home is low.
No smoke, no bad noises. There had been coolant leaking at the head gasket externally, but the re-torque seemed to fix that, or it sealed itself up.
I'm thinking I should pull the head and inspect the gasket. Did I miss anything, though?
