ryanroz Posted 11 hours ago Report Share Posted 11 hours ago Hello, I recently picked up a used 2019 GasGas 125 for my son and I can tell someone has been into the carb. Can someone please tell me what the stock jetting is for a newer 125 with a Keihin at sea level and what jetting they typically use? Thanks!

lemur Posted 11 hours ago Report Share Posted 11 hours ago Carburetor performance is dependent on the engines ability to move air. Highly recommend you inspect the reed valves, test the engine compression and the integrity of the bottom end seals first. The engine needs to move air efficiently for the carburetor to operate to its best efficiency and no amount of carburetor adjusting can overcome that.

ryanroz Posted 9 hours ago Author Report Share Posted 9 hours ago Thanks @lemur. I get all that, just looking for what the stock jetting was on a 2019 125 or a new GasGas 125. The 125 is no longer sold in the USA Quote Link to comment Share on other sites More sharing options...
lineaway Posted 12 minutes ago Report Share Posted 12 minutes ago The only thing Torrot shows was the 125 took a 52 pilot jet. So what elevation are you riding at? Quote Link to comment Share on other sites More sharing options...
