1999 Yamaha VMAX 600 Jetting Question

[powderhoundbrr]

I have a buddy who just got the above mentioned sled handed down to him from a farm in Saskatchewan. He is planning on using it here in the mountains as an access sled.

We took it out on the weekend and it was running super rich which makes sense as it came from the lowlands. I am not sure what jet size it has now.

Can someone recommend a jet for elevations around 4000 - 8000 feet?
