Sorry guysIve had a few discussions about horsepower in my life.
And that was invented some years ago to combat a guy who had a 350 hp chev and the only thing faster was his mouth.
I was only joking and didnt mean to target it at anybody.
Sure SS use it I regard you as a friend.
sweet as SS ive been enjoying the tailend of summer riding on my big bad 50.
I get surprised how serious some big bike riders get as they race from redlight to redlight and i sail pass as they are still taking offI just think this bike is that slow the light will be green when i get there

Loydys Lambrettas Two Stroke Piston Diagnosis
PERFECT BROWN CROWN
The crown of this piston shows an ideal carbon pattern. The transfer ports of this two-stroke engine are flowing equally and the color of the carbon pattern is chocolate brown. That indicates that this engine's carb is jetted correctly.
FOUR-CORNER SEIZURE
This piston has vertical seizure marks at four equally spaced points around the circumference. A four-corner seizure is caused when the piston expands faster than the cylinder and the clearance between the piston and cylinder is reduced. Another common problem of this type is a single point seizure on the center of the exhaust side of the piston. However this occurs only on cylinders with bridged exhaust ports. The main causes for this problem are too quick warm-up, too lean carb jetting (main jet), or too hot of a spark plug range.
SHATTERED SKIRT
The skirts of this piston shattered because the piston to cylinder clearance was too great. When the piston is allowed to rattle in the cylinder bore, it develops stress cracks and eventually shatters.
SNAPPED ROD
The connecting rod of this engine snapped in half because the clearance between the rod and the thrust washers of the big end was too great. When the big end bearing wears out, the radial deflection of the rod becomes excessive and the rod suffers from torsion vibration. This leads to connecting rod breakage and catastrophic engine damage. The big end clearance should be checked every time you rebuild the top end. To check the side clearance of the connecting rod, insert a feeler gauge between the rod and a thrust washer. Check the maximum wear limits in your engine's factory service manual

Didn't TZ have that problem at Taupo?
Interesting that 4 point seizure, and explination is from a Scooter shop too.
"The main causes for this problem are too quick warm-up, too lean carb jetting (main jet), or too hot of a spark plug range."
No mention of studs crushing the barrel.
TZ don't worry about those 8mm studs, just warm your bike up properly first before racing it!

Four corner seizure: Both sides of the piston will show heavy scoring and seizure marks on each side of the wrist pin hole. The pattern of these four seizure points often appears to be a perfect square, hence the slang term "four corner". The scoring takes place in this pattern because those areas of the piston casting are the thickest. When the piston is seriously overheated, the thick areas will expand and distort the most.
