:? what in the world is this class :? I see no records for this and no frame confriguration :?
-
7.g is A or altered/special construction, open class is no streamlining. 1350 A/G is 1350cc, Altered on gas, record 194+, mine :-D

Ah, once again we have the impenetrability of bike rules by car guys and vise versa for car rules and bike racers. Don't ask, Sparky -- just trust us (wink-wink, nudge nudge).
-
in the motorcycle classes there is no altered class--the A is special construction no where in the rule book will it be called altered that i can find---------------------willie buchta

Jon the impentrability is my dense foggy CAR brain---I realize that is A "special construction" but how is it designatied Open Class? so what would a gas 500cc 0pen class designation be
-
500 cc A G is an open class (no streamlining)
500cc APS is partial streamline
500cc APG is pushrod gas open class (no streamlining)
500cc APS-PG is partial streamlining pushrod gas willie buchta
-
But that's only 5 to 10% of the 2-wheeled 500cc classes, rite?

Thanks Willie!!!!!
-
actually there are only 8 frame classes ---6 at el mirage in the motorcycle classes ----in the car classes there are 16 body (frame) classes
-
So that means there are only 1/2 as many MC records possible?
Stan
-
So -- "open" means the "no streamlining in front of the driver" class, and "special construction" means the altered class. The two are not necessarily related. That is, I've got a record in naked modified (a/k/a "open modified) and a record in "special construction partial streamlined" a/k/a altered partial streamlined.
Got all this?
-
stan NO there are more classes than that ---8 frame classes--19 engine classes and 15 engine size classes ---dont do the math because you cant run some engine classes in some frame classes an example would be streamliner production or production fuel ---omega can only run in APS--
slim i think your pulling my leg----there is no altered motorcycle class----if anyone is intrested go to page108 and 109 in the 09 rule book and see the lists for frame --engine--engine size ----you can also go to page 176 177 178 179 to see all of the vehicle entry codes willie buchta has left the building
-
Then what does the A stand for in 1350 APS/g
-
page 154 11 C
-
and page 108--page115--page177 24 times willie buchta
-
A stands for special construction makes sense right. I maybe wrong they may have started out calling the class altered but the chassis modifications in the class are greater than most altered car classes, no production parts need be retained and they don't need to resemble the production bike in any maner.
-
i knew that was next so i got out the oldest rule book i have 1984 and looked up the A motorcycle class guess what it was called unlimited
-
For Bonneville Page 39 of the '76 book has same frame classes as the '84 except no side car provision.
For Dry Lakes page 49 of the '76 book, "Motorcycles participating in Dry Lakes competition are allowed to use any type of frame or streamlining that is consistent with the safety rules and good design practice". No separate frame classes.
'69 book had nothing on motorcycle classes. Page 1 "Inquiries about motorcycle competition should be directed to Earl Flanders, AMA Referee, [his contact info]."
I should have 71 and '72 books but haven't seen them in years.

WOW :-D :cheers: :cheers:
-
on the same page something i thought was interesting-------------willie buchta
-
This is kind of funny :cheers:
The "A", does not stand for Altered(like I aways thought), but stands for special construction.
I wonder now with the new rule changes over the last few years if the "P" in the APS class now stands for "MOSTLY".

in my earlier post (pic ) you will see that the PS was production supercharged but A supercharged was AB there is probably a good reason but i cant figure it out ---now all of the supercharged classes are B --looks like they had it right S = supercharged then changed it to B = supercharged----the only thing i can figure is they didnt want to get the S confused with S for streamliner or streamlined--if thats the case when they changed from S to B why didnt it change from supercharged to blown ----im getting a headache willie buchta
-
S vrs. B
S(supercharged) was changed to B(blown) for the bike classes in order to conform to the car classes.
All in the name of consistency.

It's always better to be blown... :evil:
-
If supercharged is "blown", then turbocharged must be "sucked"
