Lectrons seem to have their niche.. I usually only see them on drag bikes and hillshooters.   I have never run one but i remember several guys futzing with them about 10- 14 years ago at the mx races i used to run.  They were all on banshees and big bore hondas i was running against in the open 2 stroke class.  They never could seem to get them to run consistantly for mx or regular play riding.
Maybe they didnt know what they were doing, and maybe newer lectrons are better, but for average riding, reliability, and ease of tuning, i saw enough of the lectrons without spending my own coin on one.
I beat many a faster rider/ bike due to the inconsistant performance of their engines. 
When i saw 3-4 guys at the gate,  nervously fiddling with their carbs, i knew I was gonna have my opportunity during the race.
