Agreed! The rules need not be ridiculous, just clear.
NO engine mods or "improvements" of any type!
No degreeing cams, valve seats, head work, high compression, lightening, etc.
DON'T EVEN OPEN THE ENGINE UP! (except for valve adjustments)
Jet it, stock airbox required, exhaust of your choice, no total loss, shock OYC, mod fork internals, clip ons, rearsets,
1st gen bikes can use late model EX250 wheels, stock master cylinder, braided lines & brake pads OYC, bodywork OYC, (although WERA is VERY strict on the bodywork thing).......
mostly, just don't be "that guy" about it.
If you feel it will give you some advantage over the field, don't do it!
Let your riding be what beats all the guys that finish behind you.
The minute someone shows up with flat slides & cams, the class is ruined!
I'm trying to get the rules amended to reflect this.
