One more project to start for today. I needed a good spot to mount my data logging equipment. As you are all aware, there is not much room on the 14. I decided on a spot under the seat, where I had previously mounted the power commander:



I found a piece of scrap metal at work that I wanted to try to make a base plate out of. After measuring the room I would need/have, I marked the plate for cutting with a jigsaw:



There were several areas on the undertail that I had to cut and dremel so that the plate would mount flush:







I painted the aluminum base plate with some Krylon and mounted it in place:



Here is a general idea of how I will mount the equipment:



I have a few things left to do. I need to seal the large hole in the undertail to protect everything from moisture. I also need to relocate the Power Commander to the front of the bike. Then I will check for clearance again, and attach the equipment to the base plate.

I hope to complete this tomorrow, and install the ignition module at the same time. It will be awhile before I can get the logger wired and setup, but at least it will be in place.

hey Shane... Im sure you've discovered the huge unused area beside/behind the battery (to the shifter side of the bike) behind a plastic cover? At a glance it seemed almost large enough for a second battery. I thought about putting my pc in there as the battery ground is close. No room under the seat and then all this room going to waste? It doesn't appear to get wet in there. just a thought

I think I am going to mount the dynojet stuff up front like they suggest. I will have to extend the ground wires, most likely, to get a reliable ground. The area next to the battery has my shifter solenoid, and will likely be housing some nitrous stuff in the future.

Someone was asking how much room there is with the step seat. Here is a picture:



As you can see, it is pretty compact. I am 6'1 203 lbs....it is a tight fit. They actually make a more compact seat as well, for smaller riders.

Shane, since you have installed the Catalyst seat have you noticed any problems
with it rubbing anywhere or did you trim it so that would not be a problem? I
appreciate the time and effort you have gone to, to document your progress.
This is very informative. Also, you and I are almost identical in size, how does the
seat fit / feel?

Yes, it has left some rub marks in the paint. In fact, if you don't do something, it will really tear things up. I put some rubber hose along the edges:



It has still left some rub marks. Even under the seat pan, and on the tail section. The seat feels very good. You really drop down into the bike. It won't give you much room fore/aft, but for racing you don't need it.

Sanding the edges to prevent contact and padding is needed to be glued underneath to prevent additional scratches when sitting on the seat...

On the 14, the fuel pump will smack the swingarm if you lower it too much. I wanted a stock arm that I could experiment with, and have modified. I picked this one up cheap, from a board member:



I had heard that the stock arm was very heavy, but I was surprised at how light it felt. It turns out that it is not quite the boat anchor that I thought it would be:



Later, after it is modified, I will weigh it with the chain guard and extensions installed. All major modifications are on hold until after the Maxton Mile next week.

The Maxton Mile is this weekend. My bike is fairly unchanged from the last time I was there, with one big exception: the air shifter. I had been mounting my CO2 bottle on the side of the bike, but was informed that not only was it not likeluy to pass tech inspection...but worse, it was unsafe. Particulary in the event of a tipover, the regulator could snap off of the tank and with 1000 psi in the tank that would not be good!

So I had to figure an alternative means to mount the bottle. I tried various ways of protecting the bottle on the side of the bike, but in the end I decided to move the bottle to a safer location.

I am running a Catalyst step seat at the dragstrip, and I called it into duty for the mile. It is hollow underneath and gives some room for mounting. I also ordered some smaller 3.5 oz. CO2 bottles, figuring they would be easier to deal with:



I cut a bracket from a piece of scrap aluminum:



Instead of stainless hose clamps (won't pass tech), I decided to use heavy exhaust clamps. This would be much more secure. I drilled the mounting bracket accordingly:



Here is the spot where the bracket will mount:



I removed the seat latch and attached my new bracket assembly solidly to the subframe:





Here you can see that the seat provides plenty of clearance and coverage for the bottle and regulator assembly:





All I have remaining to do before Maxton is change my rear wheel and sprockets. I would like to see 190 mph this time. I'm hoping the shifter will give me the boost that I am looking for.

Well, it's about ready to go to Maxton. I changed the gearing this morning to 17/43. That is about 1/2 tooth taller than the 16/41 that I was running. I did that so that I could shorten the bike up a little for better traction in the lower gears.

So, this time out I will be running the following changes from the last trip to Maxton:

Shorter Wheelbase
Slightly Taller Gearing
Air Shifter
Step Seat



I'm also taking the stock windscreen in case I get a chance to try it vs. the double bubble. Last time I went 186; we'll see what a few changes and the cooler weather brings.

That's what I switched to, a 3.5 oz bottle (look closely above, it is a tiny bottle mounted!).

Well, it rained almost all day here at Maxton! They stop the runs at 6 pm, and I made one run at near 5:30. Not many people got a run in today; I was one of the lucky ones!

The run went pretty well, if a little tentative. I have to get used to a new tuck with the step seat, and this is my first time using the shifter at the mile. As I said, I am trying for 190 mph this weekend. Here is what I've started off with:



Not bad! My gearing calculation is pretty darn close; I have roughly 200 rpm left in the bike before I hit the rpm limiter in 6th. I'm hoping that a good nights rest and cool morning air will get me to 190 mph tomorrow.

We got to the track at 6:10 am this morning. I rode the bikes up to the starting line in the dark to get a good spot in line. The weather conditions were very much improved in the morning. Unfortunately, my first run was another 189 mph pass. I suspected that the bike might be running a little lean in the cool air, but I didn't have my data logger hooked up to check it.

I decided that I needed to try something different. I installed the stock, shorter windscreen. I thought that it might help since I had been told by a couple of sources that the double bubble was not as aero as the stocker. Well, by this time a small headwind was developing. My next run netted a disappointing 185 mph.

So, I switched back to the double bubble and gave it another try. Another 189 mph pass. I was starting to think it just wouldn't go any faster! I went ahead an installed the LM-1 logger so I could at least see if I was running lean like I thought.

Finally, things went right:



My gearing was just about perfect. I hit the limiter right at/after the end of the traps. The logger also confirmed what I suspected. The bike was running about 13.7:1 a/f at the top of 6th gear. No wonder it wasn't pulling hard in the last couple hundred rpm!

I'd say that there are a couple more mph left in the bike with a good tune. I'm still very happy to run near 191 mph at 225 lbs. suited. I'm definitely not jockey-sized:



Here you can see that the concrete of Maxton can be a little abrasive on the tires:



Anyway, that's about it from Maxton. My 190 mph mission accomplished! One final pic from trackside:



Next week it's back to more prep for the dragstrip!

I haven't richened it up yet. I only logged the last run. So it still ran 190.76 at 13.7:1. I'm going to make adjustments the next time I'm at the track. If it still shows as lean as it did at Maxton, I'll probably start somewhere around 3% added fuel from 9-11k rpm at 80-100% throttle, and then check it again.

I just need to get the topend in the ballpark for racing, and I don't have to worry about getting it perfect everywhere right now. It is still very smooth throughout the powerband. In the off season I am going to learn as much as I can about mapping, and try and make an optimized map including the midrange (very important for launching the bike).

Thanks! Congrats on your new best as well.

I think that with some work and riding adjustmets I can get to 195 mph or so on the motor.

Seems to me you made a good choice buying the 14...

Your accomplishing all your speed goals with this bike
