Jetting charts

[1badz]

Anyone have a main jet chart? 02 Viper calls for 156.3 mains. Bought it used with 153.8's. How many sizes is that down?

153.8 is 2 sizes down.....depending on the temp and elevation you ride at.

I scanned a jetting chart so hopfully it is readable.

 

[..SNAKEBIT..]

is this chart or charts somewhere on the site? or web?

I just had my dealer photo copy it for me.

Am I reading right that from -7C to -18C, at sea level the chart suggest 157.5? That's 3 sizes from where I'm at. Are these charts relatively accurate, or do they give black plugs at these suggestions? Thanks

Your reading it correct. Stock jetting is 156.3 mains good for -18c to -7c at 100-500m. The jetting chart is considerd to be "safe" jetting so you can count on it being a bit rich.

If your having trouble reading the chart let me know...I can e-mail a larger image.
