I took apart the engine shroud and there I saw it was impale from inside the case just below the cylinder, right in the middle of the engine CASE.
Its something off of the crankshaft, maybe even the piston rod split or something.
I took out the head down to the cylinder with piston inside. I couldn't get the piston to pull out or tap in lightly.
The piece of metal looks like its coming from the CRANKSHAFT.
I just have my camera on my phone which is not the best.
I would have to Split the CASE and replace the two halves of the case and anything else inside messed up.
I took the whole engine off and is separate from the frame on a wood block to support the top end and bricks to keep the wheel upright.

3,300 miles I got it at 1 mile off mxmotorsports.com its a little over a year old, literally.
The bolt that starts at the flywheel then inwards was impaled out through the hole too.

Lucky for me I have a recycling plant a few miles down the road from where I live. Its just a pain to get to due to you have to go over a bridge with 2 lanes that used to be 4 lanes, so its a bottle neck of traffic to get there.

Rpms are 6,900-7,100 FOT going 50-56. I had 7,800 rpms with 10 gram sliders for 50 miles then I changed back to 15's.
Rollers from 9's, 10's, 12's, 13's, 15's, 16's all max rpms was about 7,000 rpms MAX on my scooter.
It took sliders to get rpms above 7,000 on mine. Of course I'm 245LBS.
Or I guess you mean we all can't ride FOT or the engine's going to blow up like mine.
I doubt that, this was bad luck. It was 5,900 rpms when it seized.
I know its to give me a hard time.

You are kidding about running full throttle. At those rpm your intake pulse evens out to the point that is almost ceases so that you end up running lean and hot causing you to burn holes in the top of the piston, loose valves and throw rods. Once you start loosing the intake pulse a vacuum pump even the Mikuni will not be able to fully keep up.

What kind of design causes detonation from normal operation?? I am unaware of any other scooter/motorcycle design that detonates if you run it WOT. Ridiculous

I don't understand why people think running an engine wot is bad for it as long as its not over revving or getting to hot it should run all day wot look at lawn mowers they run wide open all the time so do generators.
