Thanks for your answer Jean Noel,
It is possible to replace a G12 cranckshaft by an other model , like G8 , G9 ? . When i check the technical data in the book it seems that the same datas about the cranckshaft , right ?
The second solution sounds good , but i don't know if it is possible with my crankpin diameter ... around 39,95 mm
It is dangerous to regrind to 0.80 ?
In the MAOC Parts service i see many plain bearing ( central for the example) :
CENTRE MAIN BEARINGS .010 ( It is for the first regrind at 0.10 ? )
CENTRE WEB PLAIN BEARING; +020 ( It is for the second regring at 0.20 ? )
CENTRE WEB PLAIN BEARING; +030 ( It is for the third regring at 0.30 ? )
CENTRE WEB PLAIN BEARING; +040
CENTRE WEB PLAIN BEARING; +050
CENTRE WEB PLAIN BEARING; +060
Thanks for your support the team
