Post by: MGILBERT on 01 April, 2017, 15:51:55
Hi guys

i am having a misfire underload, albeit when reaching 55mph (cruise speed)/and 30 miles into ride all is well. Any ideas? Engine has recently
been rebored etc and still running in ?

Check condenser connections.
Or might Running weak on wider throttle openings. Try a slightly larger main jet.
