early 90's suzuki atv 125cc dies when put in gear Sign In

atv given to a freind years ago, been running fine. Suddenly when he puts the bike in gear the motor dies. He said that battery and electrical seem fine. Somehow triggering a kill switch (seems like). he's been unable to locate a shop manual. Any guesses?

Not a tech in these but basics still apply. What's missing when it dies? Spark or fuel? You should at least be able to narrow it down to one of those,

I figure if it's spark or fuel the thing wouldn't run. It starts and runs fine, only dying when put into gear. As soon as he attempts to engage the transmission the bike shuts down. Almost like a safety feature or automatic kill switch. He and I both are pretty "wrench savy" and are stumped. I told him to take his volt meter and try chasing it down. Maybe he'll figure it out. I wish him luck

Best guess is any safety or kill switch is spark. Look and as said these aren't my expertise but machines share basic ideas,

If like some other "things" engine will quit if clutch isn't known disengaged and things like that for safety reasons. Some junk of my own will quit running without holding an "operator" present thing of varied sorts for like lawn mowers and stuff. Might even have a sensor on seat so it won't go if not sitting on it??

Unhook the wiring going to the coil, that will disable any kill systems.
Maybe have a carb problem too, sometimes when a small engine is placed under load real quick it will die.

PS: I'm a certified small engine tech.
