GS1000 VM29 jet question
The bike still stumbles just a tiny bit when I get to 6k and beyond. I have the smoothbores, K&N pods, and 4 into 1 exhaust. I changed the main jets from 112.5 to 120. I know I need to go up, but by how much?? Any help appreciated.Tags: None

Sounds like you're in the ball park. Do you know if you're a bit rich on the 25 pilot jet? Have you pulled a plug after one of those high power runs and made sure its a lean condition and not rich? Generally people don't go above 120 main jets without running smaller 20 or 17.5 pilot jets. Not to say your situation isn't an exception but I would doubt you'd need to go further than 122.5 main jets (one step up from 120) with your 25 pilot jets if you're truely running lean on the 120 main jets.
