Retro race sounds in the modern age. As hard as it is to imagine now, there was once a time in recent history when quad racing meant the sweet scent of 2-stroke oil, a slight blue exhaust haze in the air and the music of braaaaps bouncing off the trees. These days the thumping of […] More »

Ask the Editors: Do All 2-Strokes Have Valves?

ATV 2-Stoke Reed Valve

Valves on both ends? Yes, sometimes. Dear ATVC: Appreciated your article on the two-stroke power valve but have to laugh when you say the to-stroke engine is designed around using no valves. If it has a reed valve on the intake side and a power valve on the exhaust side, I’d say it is a […] More »

2-Stroke spark plug neither rich nor lean

2-stroke plugs tell a story. Dear ATVC: I recently purchased an ‘05 E-ton 90 2 stroke, oil injected quad for my daughter. I noticed the oil light stays illuminated while running. The previous owner states it’s always been that way and not to worry about it. My daughter rode it for about 2 hours total, […] More »

Ask the Editors: How Important is Handling?

Ask the Editors:  How Important is Handling?

A Honda 250R only by name. Dear ATVC: I read with great interest your look back at the Kawasaki Tecates and wondered about something. See, I was pretty young when the 2-strokes disappeared but remember clearly my local track’s gate filled with Honda 250Rs and nothing else for years (all the way until the race […] More »
