Hey guys, Just an observation on my part… If your going to reference other rules, then you should make them available somewhere.  Or better yet, just write the rules as needed without the references

1)All snowmobiles in all classes must conform to all applicable rules in the ISR GENERAL RULES AND    REGULATIONS section unless otherwise specified here.

2) The clutch cover must conform to the rule for Modified Oval Sprint classes

3) Traction devices must conform to Oval Sprint rules

I dont have copies of or know where to find ISR and or Oval Sprint rules

I've been working to study the history of classes. How they came about and why the rules are written as they are. During this reasearch I found the the MN rules (SLEDS, ORA) are very close the exact rules ISR has written for the upcoming season. So, I'm not a huge fan of the purchasing of an ISR rulebook but I'll have one very soon, hopefully I get it by Haydays. If there are racers with questions, I'll have the SLEDS/ORA and ISR rules handy and do my best to accurately and completely answer your questions.

Thanks,

Nothing like have 20 different sets of rules to try to fit into.  I wish every race track/ league would use a standard set of rules.  Seems like a fair amout of people like to race at eagleriver so why not get the rules close as possible to that?

There is no reason to freak out when you hear the letters I S R in repetition.

Switch them around some, and some people get a little nervous !!!

Not all or everyone wants to go to Eagle River, some would like to but it cost's lot's of money to go there. To each to their own. Let's say you guys do use the ISR rules and a driver comes up and says hey isn't this guy subpose to be in a superstock class & you'll say yeah what's the problem, well I know for a fact that this ski-doo did not come with a radiator in the front like you can buy at wahl bro's), that year it came with coolant underneathe the seat, so now do you bump the guy into mod or do you send him home ?
Same as a plastic wahl tank for superstock....
What now you can't handle me making a point across wait till you have a shitload of racers letting you have it. What about the 5yr thing big woopty do. If you are moving forward with times well why are you wasting time rebuilding or putting together old iron ?

Sprocket,

Where does it say anything about a radiator in SS?  They pretty much copied and pasted the rules from isr.  Yes, i agree on the tank and dash rule for those that dont go to eagleriver.  However, the last couple of years are sleds have not been to Eagleriver rules because wolf lake, sleds, and ora rules.  They have had   more restricted rules then eagleriver.  I could build a sled to Eagleriver rules, come to sleds race the next week and get thrown out of superstock because my sled does not fit.  They will most likely open the rules up alittle to allow the old WL, sleds, and ora racers to have some fun a bank oval track.   d.r.i.n.k.


What now you can't handle me making a point across
Wtf?   L*m
