Sorry Kevin. I didn't mean to go off on a tangent. I do have a question though. Will you be coming to Bonneville>


God rides a Triumph but wishes it was a Norton.

worry not.

there is no such thing as a tangent. in the end, it's all one conversation.

dunno about bonneville, though. it's never occurred to me.

maybe it should. i'm not out of money yet.

It's funny. I've been riding motorcycles since I was 13, and always wanted to race at Bonneville since I was a kid and used to read about it in Chevy High Performance and other performance magazines. It wasn't until I was about 35 that I decided I wanted to do it on an old British bike. I started out with a "high hope" attitude of joining the 200mph Club my first time out. I've learned a lot since then. Now if I set a record, Awesome! If not, I still got to race. smile

I'm thinking of maybe attending The Texas Mile this year. It's only 2.5 hours away from my mom and dad's new retirement home, and I'm actually going to be down there that weekend putting on an addition the new house.

OMG you're not out of money? Will you sponsor me? I'll write your name on the side of my bike !

Hell sponsor me and I'll make bulldog and noisey put your name on their bikes too!

You live in Ohio? For me in western NY state Bonneville is a 5000 mile round trip... Aside from actual costs to race on the salt,I would expect the trip to cost several thousand bucks...
The Triumph I built does very well considering the somewhat "mild" race engine. Taking advise from the late Smokey Yunick...build your first racer on the mild side and with reliability in mind. Spend your time on riding technique rather than chasing phantom tuning problems ...

I've always had it in my mind to get a group trailer to take a bunch of east coasters out to Bonneville and split the gas. Still a 5000 mile round trip is gonna cost no matter how you do it. frown

When I went to Bonneville in 2010, it cost $2500 in gas round trip, lodging for a week and food. You also have the save the salt fee along with registration/ entry fees and fuel. Costs for me were right around 5k with needing to buy all new gear as this was my first go at LSR. I will have to say that it was a totally awesome experience and got me hooked on LSR racing.

Hopefully in the next year or two I can make it back.

DKA, A group trailer would be a great idea but I think the trailer would need to be at least a 7'x14' for 4-5 bikes, tools and gear.

Im not out of money only because i havent yet paid for everything. Once i do that ill have to face up to reality.

On the salt, i was looking several seasons ahead.

HB, the biggest part of my motor program is aimed at making it simple and strong, rather than making it fancy and radical. And as i see it, the hardest--and to me the most interesting --part about the whole thing is the tuning. There's no shortage of possibilities for making expensive mistakes, and im trying to concentrate on learning rather than winning.

But i still want to go as fast as i can.

My bike has made exactly 10 runs down the track in three meets at Ohio. The bike went faster each at each event despite the funky weather with head winds and hot and humid. Although I did some changes I do believe it was my rider getting better at keeping out of the wind, real important on naked bikes.
And as mentioned by me,a lot of dyno testing to eliminate all the bullshit tuning tips I got on the Internet grin

The rider is superimportant. Ive chosen to lose a total of 40 pounds to get smaller and get an increase in power to weight ratio. Ive lost 16 pounds in the last 30 days.

I watched your build from the start. You did it right- start with obvious basics and then test, change, test, change, test. No substitute for that.

It's easier to take forty pounds off the rider than the bike, but a whole lot less fun!

A lot better for aero too!

That's the unfortunate truth. My beer budget hasnt had a penny removed in 30 days.

But i'm taking a 24-hour recess in four more pounds. Sanity has to count for something.

Astek racing runs the fastest 650 gas Triumph. Notice he's not a tiny guy but all tucked in on a low bike. The bars position and seat says this is a modified production bike, 132 MPH.

Fast Triumph

Gad, I'm envious. His records are listed as A/VG, A/PG, APS/VG.

Removing the gas tank from its normal location is a big aero plus. I believe that Alp's is located at the down tubes. He can get right down to about 2" above his motor. Here the shot I love the best.

he's changing his riding position by moving the pegs:





don't know whether these^^^ are the same machine.

i have the new ECTA rule book, david.

how much do the rules vary between associations?

There's almost no variation in rules by the SCTA, ECTA and the Loring Timing Association. However at El Mirage there's no modified production class.
Modified production can vary from Alp's bike shown above that are pure race bikes with custom fuel tanks and no kick starter to something like Chris Blown Income's BSA that's more or less a street bike. Mine is somewhere in between but all Triumph and has seen a little street riding.
Alp's machines are so successful because of his attention to details and refinement.

This is where I was unsure of what exactly I wanted to build. Originally, I was going to build an all-out race bike. But after coming to the realization that I don't have a budget for an all-out race bike, and the fact that I didn't want to ONLY do LSR, I decided to settle in between. So I went with a traditional cafe racer build, still sporty and stylish, still street legal, and capable of competing on any track (whether 1/4 mile, road race or LSR) by removing the taillight and headlight by a couple of bolts. I think when I finally build a dedicated LSR bike, it will be a custom chassis, possibly a featherbed frame.

See, that's where my build makes for simpler decisions. I dont need my own machine to do anything but go flat out at high speed in a straight line for about one minute. So all my decisions can focus on that, and i dont have to figure out compromises or balance opposing needs. I dont need the machine to be streetable, or to do well in the quarter, or to handle turns and twisties. It doesnt even need to have more bottom end than necessary to get up into the powerband as quickly as possible and stay there during gear changes.

Its the focus thats fascinating to me-- coming up with a combination that all works together, and then learning enough about how it works to be able to fine tune the edge every time it goes out.

Having said all that, the frame came with a title, so ill have lights and a license tag on it. Really the only purpose of a headlight shell is to sneak in some legal aerodynamics ahead of the rider.

Modified Production rules other than safety are quite simple.The frame has to be same manufacturer as engine with some modifications allowed, the bars and seat can't be lower than top of tires unless originally equipped differently... Vintage class is similar...
I chose an OIF to eliminate the oil tanks...But had problems with oil leaks from fractures on two frames grin I lowered the bike two inches, modified the seat rails closer together, home built cafe racer type seat rear set foot pegs and clip ons.
I got busted last year at Ohio for having the handlebars too low...The tech inspector made me raise them while he watched.

When the SCTA brought in the same frame and engine manufacturer rule I was really teed off. I had been running A at El Mirage but planned to go to Bonneville and run M. A bone stock featherbed complete with 19" wheels and an ancient Weslake pushrod 500. had to run in special construction. I can understand why it was introduced but I sure didn't like it. Still the Weslake managed a record 129.917 on gas.

The headlight is a good idea. Fills the gap between the forks and help punch a hole in the air. I probably sound like a stuck record but drag is the absolute killer on small capacity engines. The more you can get out of the air stream and the slicker you can make it the faster you will go.

Our bike ran it's second Ohio meet with head and tail light . The bike went about 2 mph faster...But I had made exhaust changes also so who knows.
This is how the front looked when it ran 125 mph with gauges and the Pazon ECU mounted up front..

i'm trying to figure out how to instrument the machine with an AF gauge and a datalogger, at least. the innovate instruments come with vast loops of cable that apparently can't easily be shortened, and so would end up as huge wads of wire tied up and shaking in the airstream, or folded back and forth in bundles under the tank.

AEM makes similar instruments but offers 18-inch cabling options for hooking them up. some of it could be stored inside the headlamp shell to try to streamline the electrics. i've got to figure out how to make all this fit with the smallest wind shadow.

Kevin, There have been many threads on this and Landracing.com about aerodynamics. The number 1 thought is "It's not how you enter the air, it's how you leave it." There may be a some amount of drag created by cables and junk at the front but it is rather small compared to your calves, thighs, butt, back, arms and helmet. Not to mention drag caused by the spinning rear wheel. I would love to see the run numbers of someone who made every other run with a headlight and the others without all weekend. I'm not convinced that the average speed of the runs with the headlight would be appreciably higher than those without. (I'm always subject to being wrong and my wife never lets me hide from that fact). At 60 mph you're already making a bow wave and it just gets stronger and further out the faster you go. (Think of a snow plow) "Frontal area" the big bow wave producer, is the total height and width of a rider and bike, not the shape of the things in front of the rider. And the spinning front wheel does all sorts of weird things to the air. So, wrap the long wires up against the down tubes and get as skinny and low down as you can.

The LM-2 handheld unit doesn't work with a bike with electronic ignition. RF scrambles the screen. I use their recorder and bring a little laptop.
