Hi All, I got a 2006 KLX125 for my daughter a while back, I am having a real time with getting it to run decent. Right now it has the stock carb, pipe and airbox. I have cleaned and recleaned the carb several times, checked valves etc and still no joy. I had a Mikuni VM22 I had bought a while back for my sons bike and never used so I thought I would give it a go. I bought the adapter from BBR to make it work and it hooked up fine and seemed to idle nice and clean only problem is that it has a bog right off idle if the throttle is snapped open....roll it on slow and no problem. I do have a selection of jets to try both mains and pilots in the following sizes: pilots: 17.5 30(stock in the VM22) 35 40 45 50 Mains: 95 100(stock in the VM22) 105 If I leave the main at 100 and use a 40 I can get rid of most of the off idle bog but the rpm's hang a bit when you let off. Should I be going the other direction (smaller) or larger than 40. I am at elevation of 4500ft. Any help would be most appreciated ( I have read many posts on the net and really found no solutions) Thanks all. Brian Also stock carb is the VM20SS with 102.5 main and 17.5 pilot.
