Here is a copy of a letter I sent to our D6 rep. I have a question about the rules, and was wondering if anyone else could clarify?This will be my son's first year competing and I want to make sure we are totally legal.

Now according to the 2004 ATVA rules, Class #25 - 71cc-90cc Production (8-15 years) states:

Production Classes cannot exceed maximum class displacement. Stock frame and ATV engine cases from the original manufacturer of that make and model must be used. OEM frames may have material added for strength. These changes shal. not affect frame or suspension geometry.

Now the D6 flyer I just received states:

Stock: limited to production ATVs. The following may be changed from stock: tires, wheels, internal portions of motor, sprockets, gearging, twist throttle, handlebars, grips, handle bar pads, front bumper, rear grab bar and jetting. Fenders may be trimmed. Nerf bars or suitable floorboards are required. No other modifications are allowed INCLUDING carburetors, exhaust systems, wheel base, width and suspension.

The "grey area" I see with the rules are this. It says you can change wheels and tires, but can't change the width of the machine. Now I just installed a new set of wheels and tires on the rear of my son's machine and it widened it about 4". Now spacers, axle or anything else just wheels and tires. Now before I received my D6 flyer I had ordered a set of stud extenders for the front only because if you flip the wheels over the valve stems will hit the calipers. Now if I'm not allowed to install the exteders because of the rule posted by D6 (but not by ATVA) all I would have to do is install shorter valve stems using the OEM wheels and flip them over. Thus gaining the same results. So what is the difference in using extenders versus flipping the wheels? Either way you are widening the machine yet in 1 case you are using the OEM parts.

So with this could you please clarify the rule on this for me?

 

You need a clarification from the district.
The "stock" rules you posted are the old rules for the 90 SuperStock of years past/90 limited class of last year. They have been re-vamped for the 90 production class.
Ths 2004 90 production rules state that you can do "most" anything as long as you have a stock frame and engine cases. The top shock mount cannot be moved.
If you are running a stock class then you are on a 50cc machine.
These are national examples. I'm sure that the districts sometimes do their own thing.
I'd go to www.atvaonline.com and print out the rules so you can be educated when you inquire. [img]i/expressions/face-icon-small-wink.gif[/img]

 

The way I have it typed is exactly how it is worded in the ATVA rulebook for 2004. I printed out the copy and typed right from it and from the D6 flyer which I received. That's why I'm questioning it. To me it reads as 2 different sets of rules. I just want to be legal when we show up Sunday.

 

You do have 2 sets of rules for the one class.
I guess I was a lil feeble in explaining [img]i/expressions/face-icon-small-smile.gif[/img]

 

the only stock class would be 50cc limited and the stock rules are correct,if you have a 90cc you would run under the 90cc production rules,you may have to down load the supplement to see the production rules but they are as jack stated you can do just about anything as long as it doesnt exceed 90cc,and a prod frame..
