Big bor kit

When fitting a 170 big bor kit on a 125 ped will the carb need upjetting,if it does how many sizes do you generally need to go up?

 

Check current Jet size mate, once you got the size, buy a pack and work your way up. It's very much trial and error buddy.

Anymore issues just get back to me!

 

its best to start with a big jet and work your way down, you will wreck your new bore doing it the other way....

 

I've had no issues with my ped, not from going up with jets, I was on a low jet so I worked up.

 

you are lucky then.
