So I just traded my 04 cr 250r for an 07 450sxf. I’m going from 2 stroke to four so obviously there’s a learning curve... two main things I noticed. 1.) the electric start doesn’t seem to work. It turns over but won’t start 2.) she stalls at Low rpm... I’ve ridden it for about an hour and tried many combinations...it even stalled in neutral going down hill while reving the motor... any advice would be much appreciated!
