Does anyone have any experience jetting a 2001 426 for Mammoth. I only have 4 days there and want to spend as little time as possible playing with the bike. I run an e-series with 18 plates.

One of my best friends works at North County Yamaha and they are going to provide trackside support all weekend long at Mammoth. They will have jetting specs and authorized Yamaha mechanics to get you squared away while you're there. They will also have all the jets that you'll need (and anything else for that matter). Good luck.

Does anyone have any experience with the oxygenated additive? I heard you can use this instead of rejetting.
