01 gasgas 250 ec jetting help
 

I have 01 gasgas 250 ec. I ride at around 1,500 feet ruffly. With 50:1 93 octane mix gas . It used to be 32 :1 and I want to change it to 50:1. The needle that was in it before was nozf with a 38 pilot and I could not read the other number for main jet. I have a needle laying around n1ef idk if it good for my bike or what jets to use with that needle . I just need some advise on what jet to go with the n1ef needle with 93 octane fuel 50:1 br8eg plug 1,500 feet

have a look in the local jetting database.
look for the same bike, same altitude and se what they did and rear the comments on their setting.

According to older posts the n1ef is similar to a n1eg which works very well for GG bikes. You will find lots of info on both needles.
