oh jesus this is getting complicated. i’m not going to do the work myself. i’ll have a shop do it.

it just occurred to me…if i do change all this stuff, it will affect the RPM’s because of the gearing. i’m assuming it will fuck up my speedo too? is there a way to correct it?

i’m starting to think just keep the OEM setup and just get a new chain for now.
