Been out in the garage/garden with the bike.... decided to have a look at the barrels & bits...
Took Dyna coils off, for more room... Cam cover off all sweet & dandy
Good... Megacycle cams & adjustable srpockets..... Best do clearances whilst at this stage... coz they are under bucket doofers....
Ranged between 8 thou and 1 thou

so needs some attention, hopefully just shim swapping
Notes & photo's of cams as they could be a pig to reset without data

All seems OK, no bad scores/marks....
Head off OK..... gasket not stuck too bad...

Hmmmmmmmmmm
That head gasket look a standard size... check and it is

Quick measure of bore... 72 and a bit mm

Should be 78 for a 1260cc
Barrels off next....... Bores look clean & tidy, no ridges or marks... still see honing pattern
The cases don't look particualrly "bored out"

Measured the round bit that the barrels sit in.... 84 mm diameter

Is this standard
SO, this bike was not what is was sold as
Carbs were 34 RFS, not 38's.... Pistons only 72mm not 78mm
Anyone know what the casing mouth size is std

before I contact seller

And on the 7th day... Zeds were created!
