ESA class rules?

I am having trouble finding the ESA class rules for the ESA Open Lakeracer 0-1200cc class. All I have been able to find is this:

Open 0 – 1200cc - > 700lbs. (625lbs. twin)
Open 1201+ cc - > 750lbs. (675lbs. twin)

- All snowmobiles must:
- meet weight minimum for cc class
- meet cc maximum for class
- must be full body OEM type chassis. NO lay downs or “open mods” allowed

- Material substitutions allowed for body and suspension

- Any cylinder, head, carburetor, throttle body, crank-shaft may be modified or replaced

- Any suspension allowed

- Any ignition allowed

- All engines must be normally aspirated, NO turbos, superchargers or N.O.S.

- All ISR Improved Stock safety rules apply

- Open cc crank case may be modified or replaced



I have quite a few questions.
- What are the track limitations?
- What are the ski limitations?
- Are you able to remove guages? If not, can the guages be replaced? (ie. remove tach and replace with a Digitron?)
- Do you have to have working head/tail lights?
- Are rolled chaincases allowed, if so, how far can they be moved?
- Can you run titanium drive/jackshafts?
- Are open stingers allowed?

do they have a web site that would allow you to contact a knowledgeable person
