It would be helpful to know the correct gap for a lem 50cc atv spark plug. Trial and error works but not ideal.

 

From the Denso site:


LEM

YEAR 2004-1997
ENGINE 50 cc
APPLICATION INFORMATION Cayman
STANDARD STK# 4037
STANDARD PLUG# W24FSR
IRIDIUM POWER STK# 5380
IRIDIUM POWER PLUG# IWF24
IRIDIUM RACING STK#
IRIDIUM RACING PLUG#
GAP 0.028

 

This is a 1999 model but I would imagine that they would probably be the same. It is a good place to start anyway.

Thanks again.
