laser1 Posted August 3, 2012 Report Share Posted August 3, 2012 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? Quote Link to comment Share on other sites More sharing options...
copemech Posted August 4, 2012 Report Share Posted August 4, 2012 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 Quote Link to comment Share on other sites More sharing options...
spinner Posted August 4, 2012 Report Share Posted August 4, 2012 105 main jet will work ok! I have had to put up to a 52 pilot in to get good repsonse Quote Link to comment Share on other sites More sharing options...
laser1 Posted August 4, 2012 Author Report Share Posted August 4, 2012 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. Quote Link to comment Share on other sites More sharing options...
