Hey guys, friend has a 90 or 91 x2 with the 650 motor. Just got it all back together and after it sits for 2-3 days battery is dead. Have tried with 2 different batteries so I am pretty sure it isn't the battery. Cables are good. When you hook up the pos and neg cables to battery there is a momentary spark so it would seem to me there is a draw as my 650 stand up is just about identical and does not do that. What could cause a draw on this system???? Thanks in advance. :dunno:
