Was not mine, just provided a link to someone that had that issue in reply to [estoma] posting, the final solution can be read on page 10
Damaged crankcase with pictures -- FIXED
Thanks for all the information. That is a textbook brittle fracture. It would have taken a substantial load to snap two ribbed M10 bolt-bosses off simultaneously like that. The truck on which the bike had been loaded must have jolted through a sharp ditch or hit a bump in the road when that happened.
Ratchet straps, most commonly used to secure bikes to load beds or trailers, are generally rated from at least 500 lb (225 kg) to as high as 3000 lb (1360 kg) without necessarily seeming out of place. And it is effortless to overcook it with these when tying down a bike, especially giving it that one extra stroke 'just to be safe', nevermind when the bike is tied down on its side/jiffy stand as well.
The new Rocket weighs around 880 lb (400 kg) wet. Add a heavy rider and passenger (400 lb / 180 kg), and we have 1280 lb (580 kg) total. The new Rocket leans over 8 degrees on its side stand (my Harley does 16 degrees, twice that, on its jiffy stand). At 8 degrees, roughly 15% of the bike's weight will bear on the side stand. Let's say it leans over a bit more with both rider and passenger on the bike while it is on its side stand - improbable but not impossible. So, 10 degrees translates to close to, say, 18%. Imagine the Designer using a safety factor of 5.
1280 lb x 0.18 x 5 = 1152 lbs (525 kg) might, therefore, well be what Triumph designed the side stand to sustain—more than reasonable. So it will conceivably survive pivoting the bike on its side stand, even though that is NOT recommended.
Now imagine the bike alone on its side stand inclined at 8 degrees. 880 x 0.15 = 132 lb (60 kg). Add four ratchet straps tied down to only half their rating - 250 lb (113 kg) each, 1000 lb (450 kg) total. This is a live load, though, so each of the two wheels and the side stand sees a third each, 333 lb (150 kg). Now apply all of that as a shock load (hitting that bump) by multiplying it by three (minimum).
(132 + 333) x 3 = 1395 ilb (635 kg), clearly exceeding our illustrative design margin.
We cannot demand bikes that are forever lighter, more powerful and faster yet wish them to remain built as strong as locomotives. And dare I say it; idiot-proof.
