What gap for you plug are you using
Bought and built my bike (Chinese "80cc" 2 stroke purchased off E-bay) about a month ago and have had no problems at all. Ride to work and back everyday - about 4 miles round trip. I live in Gallup, NM at about 7000ft above sea level and pulled the plug last night to see if it was running too rich. I have not changed the stock plug. When I pulled the plug I noticed that the gap was HUGE!
What should the spark plug gap on these plugs be?
