rkooienga Posted November 14, 2019 Report Share Posted November 14, 2019 I assume if I bored my motor from a cast 64mm piston to a cast 64.95mm piston I am going to need to change all the jets. I don’t know which numbers for all the jets. Quote Link to comment Share on other sites More sharing options...

rkooienga Posted November 14, 2019 Author Report Share Posted November 14, 2019 Awesome thanks, I really would have thought with a bigger bore that you would need to replace the cylinders. Thanks Quote Link to comment Share on other sites More sharing options...
rkooienga Posted November 14, 2019 Author Report Share Posted November 14, 2019 I am new to cylinder boring, So if I bore my motor. I already know you dont HAVE TO change the Pipes or jets. Is there any mods I need to go with this bigger bore? Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted November 14, 2019 Report Share Posted November 14, 2019 No, a bigger bore on stock cylinders simply freshens up the engine. That part will be like new again. Quote Link to comment Share on other sites More sharing options...
