What caused my engine to quit at highway speed, then restart with no further problems?

SOURCE: Overheating

If you did indeed overheat the engine to the point that is stuck, you would probably know it by the antifreeze being poured all over the ground. The bike would be really hot just sitting on it. It would smell like antifreeze and just smell hot.. I know, smell hot? but an engine that has been ran to hot has a pretty distinctive hot smell... It doesnt sound like an overheating situation if none of the above happened. A bike that is overheating will begin to loose power before it stops. LIke lacuna said, everything inside of the engine will start to expand from the heat and the piston will stick in the cylinder. Most of the time when this happens, the bike will cool off and restart. But, usually with problems. Warped or cracked head, cracked block, broken piston rings. These engines are aluminum and dont like to be overheated and warp really easy. If the engine is really hot, it will not turn over until it cools down enough. Im not saying it couldnt have overheated and then restarted without any problems, its happened before, but just not likely. But, if this is the case, take lacunas advice and change all of the fluids. Your oil will be nasty. Maybe get ahold of the previous owner and see if it has had any probems. It kinda sounds electrical to me. as long as the above overheating signs didnt happen. If you dont think it was overheating and it happens again, try to push start the bike to see if the engine turns over. even putting the bike in second or third gear just see if you can move the bike back and forth. If nothing else, you'll at least know its not locked up.

chek your connection where the alternator plugs into your engine casing & spray it with electrical contact cleaner

SOURCE: Engine shuts down, will crank but not start.

You need a crank shaft position sensor, located in the bell housing of the transmission. This is an extremely common problem on these.

Could be a few things:

1. Low on auto transmission fluid; this would cause you to lose a few of the forward gears (reverse is used less often so its the last gear to go Start the car and add fluid to the specified markings on the Auto Transmission dipstick
2. Bad auto transmission fluid; Check the fluid, if its brown and gives off a burning smell, it needs changing along with the filter
3. Bad transmisssion; if neither of the above are true, then it sounds like the clutches have burned out on the transmission or the transmission itself is bad; if 1 or 2 hasn't solved your issue the car needs to be diagnosed at a reputable transmission shop; Make sure they lay out all of your options and if you decide to have a major transmission repair done, the Kelly Blue Book value on a similar car similarlly equipted in exellent condition is about $6,800 retail

I guess you will have to reset the air-mixture screws of the carburator/s.
Not bad if you check the condition of the spark plugs...if its ..'Whitish' means lean i.e. less gas in, Brownish...means ok, 'Blackish'...means too much gas in .....'rich'
In your bike's case you may find it 'whitish'.
Hope this helps !
