August 3, 201214 yr What do folks run for Jetting on a 2012 GG125 with Dellorto Carb? My buddy is trying to get his sons 125 to pickup quicker. I have no experience with the 125's. His current setup PHBL26 105 main Clip in 2nd slot from top 45 Pilot - seems too big? but he says that's stock and what was in his last 125 that ran good. I use a 38-40 in the big bikes? I dont know what slide - Do they come with the same as the big bikes?
August 4, 201214 yr The main sounds too small to me. A 125 just does not have the volume to draw up fuel as easily as a big bike. I am thinking 120-125 range
August 4, 201214 yr 105 main jet will work ok! I have had to put up to a 52 pilot in to get good repsonse
August 4, 201214 yr Author I was wondering how the lesser vacuum draw of the 125 would effect things. I'll have him throw a bigger jet in and see if things improve. I admit im still confused (very easy to do these days...) as I would think less air in would mean less gas is required. Testing is easy enough, so we'll start rich. Thanks.
