Blurry memory, think Armstrong were experimenting with 180 on modified 256. not sure they got far.

How high are you going to rev that flywheel, and is your hospital insurance up to it? (I'm not kidding).

A good call. We used to race on airfields. Suzuki cranks used to shear with std flywheels when you revved them much past 11k.

I saw one once, bit like the ballbearing spun up with an airline; it dropped on the ground & sat still for a moment, then shot off like MJ.Fox's Delorean hitting 88. Luckily no one was in its path. We never found it.

Armstromg did their own motor and a 350 as well I posted the patterns a while ago.
I'm pretty sure I posted the armstrong story eons ago. Could dig it out.
They could have done a 180 not sure.....

Armstrong stuff that would not fit.

Diesel Pig had one of his MB flywheels pass him going into the hairpin in one race

For chassis packaging and getting the front pipe away from the front wheel, doing it the down angled KR250 way, but with the Rotax tandem gear setup and the
gearbox stacked underneath would be very trick.
But for a real super trick setup plant a pair of RSA cylinders side by side with a rotary valve offset out each side of the case - or maybe do it with a single rotary valve in the middle
like many older Ski engines had.
Bartols parallel twin firing at 90* with a balance shaft was technically superb, but if it could have been done with RVs on the back replacing the reeds,then Honda should never have won the final GP250 year
using a rider that now cant ride his way out of a brown paper bag..

I think that's a bit tough on Aoyama. I think he rode the 250 brilliantly, but had some bad luck when it came to going 4 stroke.

Honda was handed the final 250-title because of Aprilia's policy to lease works bikes to several independent teams. Their riders battled each other for points (and on more than one occasion ran each other off the track) and the slower Honda profited.

That's very cynical. Had the best rider been on an Aprillia, he should have won. End of.

It wasn't a MB (I have ever lost a MB flywheel) it was a GP100 because they have f**ked up gear ratios, I went one gear too many down it did million revs and bang straight out of the cases.
It pass me into the hairpin.

Yeah one time at (band camp) Manfield I saw Ray Wilsons flywheel come off and came uncomfortably close to beaning Pete Sales who was flagging. F5 you were there, the same day you rode my first version TZR100.

The best rider, Super Sic should have won the title - but several DNFs and a DNS in the first race,not generally his fault ruined the season.
He had more wins and poles than Aoyama, who generally won when the other quick Aprilias werent even racing him.
When the quick satellite teams all managed to not take each other out Aoyama came 4th or worst.
Frits is dead right, the satellite teams Vs the factory,cancelled each other out ,points wise,so many times they gave the title to Honda.
When Sic and Aoyama went 4T who was at the front and who was down the back - bloody obvious, still is , and nothing to do with luck in my view.

Stick to building engines, you suck at understanding a race season versus a single meeting.

If Simoncelli had been the be all and end all that season, no one would have been near enough to fuck his season.

Your argument hinges on the very point I made. It implies that the bike didn't have anyone particularly good on it, since anyone on the same machinery could throw a spanner in the works.

Did it come off the taper or snap the end off the crank?

Came off the taper.
