MAC Track was a success! There were a lot of challenges that popped up, and we're going to be really busy this week making sure we're ready for REFUEL at Leguna Seca. There are a ton of photos and videos to go through, but little time to do it! We will try to get everything available ASAP!

The plan of attack to keep the axle from spinning in the stator without being able to clamp it in the mill was to drill holes that cut through both the hard steel axle, the stainless steel sleeve and the aluminum center stator support. Then we pounded hard knurled steel pins into the holes, and welded all of it together. This should help the motor stand up to the one hundred plus foot-pounds of torque that this motor dishes out.
The screen enclosure for the liquid cooling system is almost finished, just need to mill the lexan faceplate and paint it.The top line is for the infared temperature sensor that is pointed at the outside of the motor, and the second line is for the thermistor that is inside the motor (not connected in photo). When the temperature gets above a certain level a pump gets activated and sends water inside the motor, where the heat from the motor will turn it into steam, which will escape through the side vent holes.
Towards the end of our Santa Cruz trip the bike stopped working. Scoping the hall signal outputs it was determined that a hall sensor had been knocked loose. After tearing into the motor, we found out why the motor stopped working, and it wasn't good news... The axle twisted in the center aluminum stator support. It was only stopped by the hall sensor being pulled out of its slot, confusing the controller. After that happened, the two broken shear pin pieces beat up the ends of the lam stacks, luckily the magnets kept it contained to the lams, and they left the windings alone. Should be fixable by mac track on Friday. Hopefully.

A fresh new Italian 415H racing chain has been put on, and the new controller has been installed! It is running only 70% power until we can get it on the dyno tonight. With the 420A controller geared for 100mph, it pulls harder than it ever did geared for 70mph with the lil 250A controller. Can't wait to get some numbers from it tonight turned up to 100% !

Woo! The paint was pretty close to the leathers! Got Chase on the bike in gear and got the suspension sag all set up, and I don't think I'll have to trade any of the springs. Just a little shim to take up the unused 5 or so mm that is default on 2003-5 kyb forks.

The bike is back together! And with a new top end rev speed limit of 104 mph!The Rev limiter is set at 3000 rpm. 30-72 gearing on 415 chain. The new controller (size 4 sevcon, thanks hollywood electrics!) should be making about 270 lbs of thrust with this gearing. 6G isn't half bad!

We've taken the bike apart so we can paint the frame and add some more support to the swingarm. Unfortunately there was about 6 oz. of water that came out when we turned the bike upside down, so we'll need to dry out the inside before we do any painting. Also replacing the old dropouts with ones that are shorter and thicker.
