MP3 500 HPE Sport 2019, 2000 kms.
From cold start idling 3mins. the exhaust manifold from the head about 4-5 inches is glowing cherry red.
Same in ECO or Normal mode.
Checked one of the spark plugs (NGK MR7BI 8 ) looks normal, not burnt.
Idling is steady about 1700 rpm, running ok, when the clutch disengages eg., going slow down hill there is some spitting/"burbling" in the exhaust
Is this normal?
