Gates 8jp vs gates 8dn

[bleedyamaha]

40C4313 its the direct replacement for 8jp as far as washers I don't know you will have to check that out yourself I use a team secondary.

8jp you should use the stock washers that are on the back if ya use a 8dn then you will need to add a extra washer to each of the bolts on the back of secondary
