Re: How to start GRUBEE GT5 Motorized Bike
go through the basics. fuel and spark.
if you're sure you're getting fuel, check the spark.
pull the plug out and make sure it's not oil-fouled from trying to start it. if it is, clean it off with carb cleaner or fresh gas.
then wedge the plug next to the head bolt or some other metal (not aluminum) part on the bike and push it through a few compression strokes and look for a little spark.
