Well, thanks again to everyone for their input. It is VERY MUCH appreciated.   :cheers:

As far as going 200 the first time out- maybe I have given the wrong impression. It is NOT my intent to do that, but rather to understand what skill-set is required (I'm trying to figure out what I need to work on, and IF I can work on it anywhere but Maxton). In my track (road racing) experience, it's usually the best student who asks the most questions (and learns from the answers) that excels.

Maybe I should go about it this way.......

Here is video of where I'm at skill-set-wise.  Though I'm not going anywhere near as fast as you guys do, I am very comfortable at speed. Slamming on the brakes from 135 is something I don't think twice about. Headshake at triple digits (although not in the video) is something I don't think twice about (with help from Scott's). I feel as though I have a pretty disciplined right hand, given the lean angle I'm used to (even though I AM on an SV650).

In addition to that, I'm pretty good at knowing my limits. I don't want to hurt myself any more than you guys want to see me hurt (really, thanks very much for the concern!). I've never been one to dive in head-first before I know how deep the water is.

So.......
-do you guys think there are any skills from road racing that translate into LSR?
-what kind of changes in setup and riding technique affect speed? (suspension setup? body positioning? is more a matter of being able to get the power down?)
-what are the fundamentals? (In road racing Keith Code's "a twist of the wrist" books are the agreed upon standard)
-what did the person that got hurt doing 191 do wrong? (with all due respect to that person, going roughly 50% above the limitation set forth is asking for trouble)

Again, and I can't day it enough, thank you all very much for taking time out to read my posts and answer questions. Take care.......

Grant, if I understand the previous posts -- the person that went 191 on his first Maxton pass died as a result of that pass.  May he rest in peace.  I do not know the details, and feel it best to let the subject lie.  That is, the ECTA investigated the crash and didn't release the findings to me - or the rest of the racers.  If it is known just what happened - I'm not one that has the knowledge.

Skills that translate from road racing to LSR?  Unh, throttle control, because you're very likely to experience wheelspin, especially as the bike's speed gets higher and higher on a run and the aero effort required becomes larger than the amount of power you can put down through the contact patch.  This generally isn't a concern at paved tracks -- but at Bonneville and El Mirage it is an absolute requirement.

Learning how to optimize your tuck is vital, since (as mentioned above) the aero wall is real and is also the best way to increase speed for a given horsepower.

Suspension adjustment is important if you have one (not a small number of bike LSR racers run hardtail, although there are good reasons why you should approach that carefully).  It's partly personal, partly setup for the track where you're running - another good reason to visit an event and get first-hand information from the racers running that day.

I've attended the four basic Keith Code schools - and not a whole heck of a lot is directly transferable to LSR, although the familiarity that comes with the courses makes it easier to learn the new stuff that'll present itself to you when you're making a pass for land speed racing.

Back to you.

Grant, Most of the men/women that run here have drag racing backgrounds, but many of them may well be roadracers too. One guy you might want to talk to is Greg Neal of TNL Motorsports. I know he comes from roadracing. I come from a background of riding motorcycles on their sides which REALLY should not transfer to LSR.

Is the 50 shot the you refer to wet or dry? Is one easier/more cost-effective than the other?
What is a "flashed" ECU?
Looks like you're located pretty close to me. Know of any good tuners?
In regards to folks with turbos not getting to 200 the first time..... What are the obstacles they have to overcome, if they're not lacking in the machinery department? In my experience at trackdays, the largest obstacle for people to overcome is psychological. Is it the same thing with LSR? Getting a feel for the course? Good ol' fashioned cojones? (BTW.... I really appreciate this kind of insightful advice)
Thanks.

First, There has been software released that allows the ECU to be reprogrammed on the Busa.  The "flash" ECU can replace the need for a Power Commander and all of it's various components.  Plus you actually get more REAL control of the motor.
I've tuned my Busa (via flashing method) so the ECU controls the fueling and timing for both all motor and dry nitrous.  THe ECU even controlls the nitrous solenoid.
It takes a while to get the hang of high speed tucking, controlling the bike at uber speed, and mentally prep'ng.
I'm going ahead a state this: setting a Busa up for the highest peak power on the dyno and/or getting it down the 1/4 mile track the quickest, isn't the setup for the 1 mile or further.

Alternativley buy a 20year old dog of a bike build it tune it and run it, your really getting into the spirit of LSR then.

There seems to be this fascination for 200mph for some reason where is the challenge of doing it on a bike that is just about capable of doing these speeds already, if you wait 5 or so years you will be able to go to your honkawasuzisaki shop fork out your hard earned dollars and get a 1000cc bike that will do it straight out the box.

I have the upmost respect for anyone who runs at any speeds on the salt it is a dangerous sport that we all love and take part in, by the way and I am not trying to diminish the achievement of the 200mph figure just how we get there!

records aside Is this the way we are heading cmon guys there is more to it than that or is there?

I am stickin with my old dog till it breaks a record me or the bank!

Will never own a Busa on principal Oz!

ps I asked this question when i returned quite disheartend after a poor or what i thought was a poor performance in 09 as it happened we learnt alot and it was a good performance but the thread may be of use to you,I particulaly like Joes Quote which made me decide to run with what I have.

Slim, if I've offended you in any way, I'm truly sorry, as that was the opposite of my intent. I may be overly-enthusiastic.

Thanks again, I appreciate everyone's input. I'll wait 'til my rulebook arrives, get to reading and go from there.

One thing you might want to consider is who you want to work with.  There is a Ducati shop a few blocks from my house that has always treated me like a loyal customer despite my only having purchased leathers and minor service for my Ninja 500 from them.  They are a big time road racing shop but several of the folks there have shown great interest in my LSR efforts.  I have wanted to do a project with these guys for years, so despite the fact that a Ducati is uncompetitive for ECTA records and has a snowball's chance at getting to 200 mph, I bought a 996 from someone who works there and am going to have a lot of fun seeing what can be made of it.  Going to altered class from production will be a joy and I do plan on experiencing 175 mph on it.  Then I will see if 200 mph interests me from that point.  

Many, who just don't get the joy of LSR, ask me why not just buy a MeToo and get'r done.  My response is what if I decide 175 is fast enough for me?  No challenge getting that on the busa.  

One little comment on the previously mentioned incident at Maxton.  The rider did not follow the golden rule of making passes of 125, 150 and 175 mph prior to going all out. he payed for it in the worse way unfortunately.  My suggestion is come down to Maxton with something capable of 150+ and get licensed up 175mph while soaking in the experience of land speed racing.  Then evaluate your goals from there.  You may find that you want a more difficult goal that keeps you busy for years and years!

Grant, your skills are well developed.  The roadracing skills will be a big help.  My background is racing around corners, too.  It has not hurt me a bit.

People are most important.  A local dealer who supports and encourages you through winning and losing makes everything more worthwhile.

Today at work I was pondering the question about a good bike for LSR.  Why not ride a Yamaha?  They are very well made bikes and they rarely get into the record books.  That would be a sorta eccentric project.  Mostly it is Susukis, then some Kawasakis, an occasional Honda, and hardly ever a Yamaha.

Lots of Yamaha's have set records at Bonneville and El Mirage....Don Vesco used several different Yamaha's... Scott Guthrie filled the record books using various displacement TZ's...Jason McVicar set many records on his R1

Hayabusa's have an overwhelming aftermarket support, just like a small block Chevy.

I don't see why a late model R1, R6 etc wouldn't do well at Maxton..someone just needs to build it. There is still lots of support for smaller displacement 2 strokes....drop a stroker Banshee engine into a RD or TZ chassis and have fun!! :-D

...my previous advice was given his goals..."see whats its like to go 200, as stock as possible..."

thats why i said the dang busa...

if he is wanting to have the most fun and have a sense of accomplishment have
have a great journey....with some uniqueness...

then definately please dont get a busa....

ANY brand will do....

Hi Grant

My background was Dirt track and Roadracing.  I have found that to be fast I had to break a lot of the roadracing habits.  I was a lot of elbows and knees and that just isn't going to get you any speed.  You will get great advice from LSR people.  Maxton is bumpy and there are some videos of our ZX-6 where you can here the wheel spin in 5th and 6th gear.  That is just places the wheel is no longer on the track.  I started with a 2006 ZX-6rr and have achieved 184.161 at Maxton and 190.118 at Loring with that bike.  We are also running a 2008 ZX-10R this year and have topped out at Maxton with a 198.887 and in Loring with 203.935.  The ZX-10 only has head and cams done.  Yeah there is a LSR front fender and race body.  We went 203 in Maine on 189 HP.  Kevin Hunt at KWS Motorsports in North Charleston, SC is the man behind our power.  Be happy to talk to you anytime about it.
2006 Kawasaki ZX-6rr (Worlds Fastest standing mile and 1.5 mile)
2008 Kawasaki ZX-10R (4 200 MPH Clubs)
2008 Kawasaki EX-250R (Multiple ECTA and LTA records)
131 Land Speed Records set since 2008
125 Land Speed Racing records (including 3 Worlds Fastest Speeds) set since 2008.

LOL Dang Busas I know I know if thats all you are after the 200 mark it is probably the weapon of choice!
but if you want to get a bit more out of the experience any make any age any condition will do just being involved is sometimes enough!

Having a good time of it is the most important thing
