Did I just ruin my bike?!?

So ... I took my 86 750 out for it's first semi-long ride tonight. I got about 25 miles, stopped at a cafe for some water, and went back outside to ride it home. I put the key in, pulled the clutch in, started the bike ... it inched forward and I realized it was in first. So I put it back into neutral, started the bike again, and BOOOOOM. I've never heard anything so loud. The sound that emitted from my bike beat the volume of any rifle shot I've ever heard. I realized I had the choke on full, and imagine I might've flooded the carbs with gas and then ignited it? I finally got it running and it sounds great in neutral, but when I switch it into first gear it dies on me as soon as I start releasing the clutch. I've tried compensating with more throttle, and regardless of how much I open the throttle the bike dies when I release the clutch.

Any ideas? I had to call a friend and have her pick me up ... I don't want to have to tow this thing. I just bought it.

I appreciate ANY help.

Thanks,
John

Sounds like two things. yes, choking a warm bike will put too much fuel into the system and you got a backfire. No problem there. More than likely, it dying when you let the clutch out in first is it's still on the side stand and the safety switch is working properly, or the stand is up and the switch may be bad. After being on the sidestand for a while, the plunger on my switch is slow to extend and the bike will die. If I reach down and pull the plunger out first, no problem. It's worse in cold weather.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

How do I manually do this? Can I complete the circuit if the switch is bad without buying a new switch? I have no idea where this switch is or what it is. I'm pretty sure I had the kick stand up before I put it into gear but I could be wrong. The bike has no problem dropping into first but as soon as I release the clutch it dies.

yup yup!.. if that isn't it.. check the boots on the carbs... I had a back fire once that blew the right air vent hose to the plenum off the carb.

Sit on the bike with the sidestand down and look near wher the sidestand attaches to the bike. Just in front is a metal plunger/pin that is depressed by the stand when it is down. Now, with the bike running and in neutral, raise the stand. Then reach down with your left hand and try to pull the plunger away from the bike (to your left). Once you do that, put it in first and engage the clutch. If it still dies, the switch is bad. You can bypass the switch if necessary.

Thank you! All I did was pull the pin out and the bike started right up. Seems as if it got stuck because of the cold. I'll make sure to oil it so that it won't happen again. You guys just saved me a $150 repair bill. I really appreciate it.

I wouldn't use oil as it will attract dirt, gum up, and make the problem worse. Use a dry lubricant like DuPont Dry Wax lubricant or spray silicone.
