71-90 production modified clarification
I know alot of you guy's know this rule book in and out and thats why I ask you . We are running a series here in TN in class 71-90 production modified is how it is worded in the "classes" offered.
rules say they are going to go by AMA guidelines in this class. There is a Hondie trx 90 in the class that the owner has admitted is a 125cc even though it has the 90 cyl (stock appearing) it has been bored and stroked to at least a 125 is this legal in this class even though the class is 71-90?????? we can hang but these holeshots are killing us.

I may be wrong but I think AMA allows 125cc displacement for thumpers to race against 90cc 2 strokes.

Rob,
in the main rulebook it says they are but what has me puzzled is in the 2010 supplemental rules updated 12-15-09 in section c sub part 6 it states that they may be bored and stroked as long as it does not exceed the class limit. so is that 90 or 125?????
I guess I am going to send them an e-mail for a ruling that I can print out on their letterhead and take to the track if it rules in our favor.

On the chart that I see it rules on 3 classes: Class 8 (90 Stock), Class 9 (90 Production), and Class 10 (90 Mod) they all state 71-90cc 2 stroke and 75-125cc 4 stroke.

Look on page 141

Calling it "Production Modified" is a can of worms in itself. The AMA seperates the two words and are not used together. Production is one kind while Modified is another. I would say Modifieds would be allowed to run also.

jandjracing,
That's kinda how I read into it. some of the things you can't do or mod in production it says you can in mod sooooo ?????
I am going to request they make a class name change before next years race series, it's not bothering me so much in our class but there is some trouble a brewin in the fitty class:rolleyes:

and Rob, your vote don't count cause your one of them 4 stroker guy's anyway:D :D :D

Haha, come to the dark side... :devil: lol

From what I've been reading though can't 50's mod up to 70's and 70's mod up to 90's and race in production? Honda doesn't make a 125cc bike so it would be the same as modding up to make it a 125.
