It looks like they took away the hp to weight ratio and only use weight now? Did I read that correctly?
Curious. I don't see an HP requirement either.
I thought it was just a change in the weights. Rather than allowing no minumum in Thunderbike, it has a floor.
Section 7 has been deleted.
That WAS the rule pertaining to dyno testing.
I would assume that is an effort to save money?
Or hopefully open up competition.
Lastly.. this made my chuckle..
added prior to testing.
(1.) Twin cylinder machines up to 700cc are required to meet
a weight limit of 470 lbs. (Tested weight of machine including rider
in leathers and boots during post race inspection.)
Looks like Ed Key needs some Cake.

So, how you're reading it, there is no HP limit now?

That is exactly how I perceive the updated rule.
It states "Section 7 has been deleted."
The section was the HP limits.

Well, you can now have 7,000HP, so, who cares?
If I remember correctly me and the bike weighed in at 480something. Where do you put 90 lbs on a bike?

That information was TOP SECRET!
Traitor!
Looks like you're going to need some cake, too, Becka. LOTS of cake! :biggrin:
What are you riding this year Becka?
1000DS. I weighed more than I thought, so I only have to add 50 lbs.
Becka - maybe they will let you and I weigh both of our bikes together and then take an average?
This rule change does suck I really liked the concept of a limiting power to weight ratio to keep things fair. In retrospect, I'm glad I didn't go crazy with the Titanium, Magnesium and Carbon Fiber - as it stands right now I should be comfortably over the minimum weight but not to a crazy amount.
I'll see you at Topeka!

Dammit!!! I'll either have to add 10lbs to my 1000ds or start drinking more beer.
well at least now you don't have to buy all the tricky electronics with 5 differant maps so you can hide all that extra horsepower just need a little shot of that special stuff we used to keep in the back of the refrigerator.
I guess I'll put myself and the bike on the scale to see exactly how much I'd have to add.

Is that what a lot of guys were doing? Also, how were people adding weight?
I always found the hp and weight numbers interesting when reading the results in RRW - how the same bikes could vary by as much as 10-15 pounds. I would figure much of that could be fuel, but who knows what else.
As for the dyno'ing - do you think it was a cost cutting measure? Or removed because it was difficult to enforce?

I assume that it was a cost to Factory Pro? Enforcement is still a "problem". I've heard stories of different maps. Never had that much financial opportunity to do anything like that. I guess it leaves some bikes pretty uncorked. Kind of sucks for those that are on a budget (me), but with LWSB based machines being more of the norm vs LWSS bikes there is some sense to be made of opening the rules in an attempt to attract a few more entries.
I think it was just too hard to enforce.
According to the dyno, my Duc 1000 DS was within a few HP of the BMWs at Daytona in '08, and they blasted past our whole little frieght train in Nascar 4 during Thunderbike qualifying....
Don't give me any BS about drives or rider weight, an extra 15 MPH when you're flat out in 6th only means one thing.......more HP or better aero, which I doubt the Beemers had.
I don't know much about the latest ECUs, but I do know that they all have multiple maps and switching between them can make a huge difference, and can be as easy as pushing the high beam or start switch a few times once the bike is running.
I liked the idea of the HP limits, but it's just too hard to enforce. At least now I'll have an excuse for coming in 10th......
Ignorant as I seem to be- does this have any bearing on the CCS Thunderbike class, or is my 996 still banned? lol
-ski
for 1000 air cooled and under it is 570lbs? My bike is 419 full tank so it will be around 400 after the race.I about 165-170,havent checked yet with all my gear on so i would be real close to the lbs limit.
i think your 996 is still illegal

LOL- of course it is.....you know, what with the amazing 112 HP and all. Oh well.

Then you are probably doing something wrong. Send it to Marc at European Performance Cycles and he will get you fixed up. I am witness to his 748 as a very strong runner, if only I knew how to ride it.
