Batteries at last.

I've been slacking off lately and have not accomplished very much on the project lately but I've been fairly busy. I finally got my batteries they were the last expensive thing that I had to buy. There are a couple more parts that I need like the throttle, cables and a charger. I have a good contact though that may donate the cables and give me a good deal on a charge for $200-300 so hopefully that works out so I can save some money there.

I did a fit check to see how things would go together and there is just enough clearance for the chain. The motor is going to be a little tricky to mount, it is designed for a straight swing arm design, but the GSX-R swing arm angles in at the front so I am going to have to come up with some sort of insert or spacers to make it work.

I also got the front sprockets and chain that I needed. I am using a ANSI 50 size chain to match the 530 rear sprocket they are the same size and fit nicely. I Actually purchased 4 different sprockets for the front so I can play with the gearing and they are only $10-12 a piece. I got 13, 14, 15 and 16 tooth sprockets to give me a gear ratio range from 4.43 to 5.46.

It is hard to tell in these pictures, but I am going to have to do a little bit of swing arm modification to get everything to fit so there is room for the chain. I am going to have to take about 1/2" - 1" of of the inside.

It's about time.

I finally got my rear sprocket that I ordered about 3 weeks ago. I was told 2 production days and 3 weeks later I finally got it and oh my is it ever big! You can't really tell from this picture so I've done a comparison from the old to the new.

The old sprocket was a 46 tooth measuring 9 1/2" across, pretty standard.

The new sprocket is a whopping 71 tooth measuring 14 1/2" across. Surpisingly it actually is not all that much heavier. The old one was 2.83 lbs and the new one is only 3.16 a difference of only about 1/3 a lb not bad at all. I did pay a little extra to get an ultralite sprocket meaning they made a bunch of extra holes looks like it was well worth it.

It pays to know a good machinist.

I've finally got my motor mount made for the Etek. Decided to go with 3/8 aluminium rather then 1/4 steel. This worked out to my advantage for many reasons. First I can now weld it to the swing arm rather then just bolting it and it made the process much faster. I went to see my friend in the machine shop and he felt bad because he kept forgetting to make it for me so he drew it up on his milling machine found a piece of scrap and in about 10-15 minutes I had this beautiful result! The drawing that I had actually had a mistake in it and he caught it as he was putting it on the mill machine and fixed it. When I brought it home to try it out it fit perfect so a big thanks to Robert in the machine shop!

Big bad Alltrax

So I picked up my controller today, it is an Alltrax 72V 300A programmable type. Originally I wanted a 450A because lets face it who doesn't want to go fast? But the Etek-RT is only rated at 300A. But I was drawn to the programmable feature of the Alltrax that way I can tweak and adjust the way it'll perform.

I am currently planing an mounting the controller here on the outside behind the forks I have not come up with another place to mount it without sacrificing a battery.

Which brings me to my next point..... getting all the pieces of the puzzle to fit together, in my case there are 6 big pieces. Here is number 1 this was the easy one.

Number 2
Number 3 I actually got pretty lucky that it fit here I may have to take a little more off of the gas tank.

Number 4
Number 5

Now the clincher that last and final number 6!!

The gas tank fits down nicely over the battery here it is only partially lowered so you can see how it fits.
The finished product!! As you can see it should still be fairly easy to get all the plastics back on I'll just have to come up with some sort of sub frame to hold it all together.
