Crashes when your engine siezes...

Thank you for the valuable reminder and lesson to all. i really hope you get back on your feet soon too. And, caring about everyone else at the same time! Legendary..!
falling off is never fun at any speed.

i was just wondering? Was it running too lean or not enough oil in the mix? good idea to let your bike warm up for even metal expansion too, and always run it on the rich side. have you inspected it internally yet? the plug? One thought! the little spring circlip that hold your piston pin in are notorious for falling out in even well respected motors (honda, yamaha) etc. The few china motors ive pulled apart have had too much clearance around the little end for anyone's good. loss of power and increased wear and increase the likelihood of it happening.

motors normally give an indication they are about to fail. power will drop and return like its hunting for more fuel. but catastrophic engine failure is a very nasty business. a piston and rod could easily smash through the case, when they are accelerating at around 70 meters a second. and suddenly stop, it can be fatal. Ive seen steel V8 blocks turned into big chunks of shrapnel by a wayward piston and rod with a gaping black hole the only thing that's left of that cylinder.

I hope you get well soon.

My worst experience was the cheap chain tensioner getting friendly with about 1/2 of the rear spokes on my shiny new Fuji Beach cruiser around 20 MPH. Never fun when you get a spoke embedded in your calf muscle. Fortunately the VA gave me a tet**** shot before this happened so the pain was pulling it out and learning a lesson. Considering the wholesale cost of these (Being an Ex WD for Grubee Im not tellin..lol) I am not surprised that one will just disintegrate while moving along.

Macka is correct.......but I am unsure as to why medical terms are eliminated.....but this is a disscussion for the CC or the White Zone.

Now Back to the topic.

I think it is a very good idea to lock your back brake in a controlled situtation to learn what to do in an emergency.....It also crosses over. Lock the front brake, kill the motor without releasing the clutch.....on old tires have a flat at speed. It would be wise to try many different things, under controlled conditions (safety first) to learn how to react in an emergency.
 
I purchased a Monster engine to get me buy till after Christmas. At which time I will purchase a Suburu. Suprinsingly the monster engine apears to be well made.

My HT was running rich on a 20:1 penzoil mix. It had about 500 miles on it. There were no sighns that anything was afoul. Upon disection it apears that the piston ring failed and wedged itself between the piston and cylinder wall bringing everything to a screeching hault. Everything else apeared normal. It even apears that with just a new piston ring the thing would run again...Not gonna try it though. It has been placed in the trash and thankfully carried off to where it deserves to be...The landfill.

Couldn't have said it better! Emergency action procedures practiced frequently can save your live. Its something you do (emergency stopping, highspeed/lowspeed collision avoidance) if you take a motorcycle safety course and something that is ingrained in you if you ever become a military pilot. Its something that also saved my wife's life when I explained to her what to do if she ever had a "runaway" engine in her SUV. Her turbo seals failed in her diesel and the engine ingested the motor oil feeding the turbo and used it as fuel...since a diesel engine has no throttle to regulate air flow and uses as much fuel and air possible at a time, the engine ran away at more than normal max power. She did good, reacted appropriately and all was ok except for the engine which was toast.
 
SLIGHTLY off topic, but still about motorized safety... this punctuates why I hate "smart cars" with all sorts of "safety" features and avoidance controls etc... people stop thinking while they drive and assume that their vehicle will do most of the work... and then when something goes wrong, they don't know what to do!

My brakes failed in my car... at the top of a hill... and while I had not practiced what to do in that situation, I still KNEW, and I made it safely to a parking lot-- under so much control that I actually parked in a marked stall with no damage to the car or to my surroundings.

And what about all of those Toyota drivers with runaway throttles? It's called "neutral", folks!

OK, I'm done with my rant...

with how inexpensive these engines are, I would do the same thing, because you never know if there was something you can't see that caused the ring to fail... something that is still there and would cause another identical failure... (I don't know if that is even possible, but since I don't know, I would play on the safe side)
