Red Returns Part 2

Red Returns Part 2!
Part 1 Part 3

With the frame back I can start the re-assembly process. I repacked the steering head bearings and re-installed the triple clamps and fork tubes. Next, I install the wheels and brake components. After bleeding the brakes it almost seems like a motorcycle already. At least it will stop now!

The next project is mounting the 3 timer K&R Pro Cube in the headlight. This is one bad ass delay box! It is the most advanced delay box/throttle stop controller out there. It will be the bike's co-brain in conjunction with the MSD MC-4 ignition. The Pro Cube will control the Air Clutch, Throttle Stop, and Nitrous System. An interesting feature is the Pro Stage. Tapping the launch button activates a second throttle stop set to hold the bike at or near idle while you stage with the throttle wide open. Pushing the launch button in releases the second throttle stop and opens the carbs to the wide open position. On a full tree the Pro Cube is programmed to open the carbs a certain pre set time before release of the air clutch/rev limiter. This will keep your routine virtually identical whether racing a pro or full tree. It also keeps your “on the rev limiter” time down to a bare minimum. This virtually eliminates getting burnt down and left to rev limit for very, very, very long periods. I’ll probably be racing 2 classes this time around. So I really like the pro or full tree select feature. The Pro Cube stores all the delay, throttle stop, and nitrous settings as a group. One switch toggles between 2 complete groups of settings.

The handlebars go on next. Of course we use a MPS Tether Kill Switch, MPS Pro Pushbutton with Air Ports, and a MPS Pro Dual Toggle to control all of Red’s functions. A MPS Air Clutch and MPS Switched Throttle are slid on the bars as well. The MPS Line Lock cylinder is installed on the rear brake to keep me from moving after staging. Pneumatics are the next order of business. To get a steady 140 psi at all the air valves all the time I use a MPS Paintball Regulator Assembly. I used one of our MPS Nitrous Distribution Blocks to distribute air to the five air valves used on “Red.” I put the air valves for the air shifter, line lock, and air clutch right on the block using Earl’s Fittings #4 AN female swivels to save space. The two throttle stop valves are remote mounted for easy access.

The entire nitrous system is hidden neatly behind the carbs. We used a MPS Nitrous Distribution Block with push in fittings to face all the lines toward the NOS Fogger Nozzles. A NOS Fuel Pump and NOS Solenoids were used as well.

The MSD MC-4 Ignition is the co-brain of the motorcycle. This ignition is like no other. Even the appearance is different. A red box with a serial port on the side. No adjustments, knobs, pots, etc! It uses a laptop or the optional MSD Hand Held Programmer to make all settings. The MC-4 ignition will control all the air shifter functions. It features the ability to shift each gear at a different rpm if desired. It also controls when to kill (no auto, 1-2 auto, and 1-2-3 auto) and how long. ( 20-99 milliseconds ) Three separate rev limiter reside in the red box. The high rev limit to protect the engine, a launch rev limiter, and a burn out rev limiter. Other timing retard features include a launch retard ramp, start retard, three step retard, gear selectable retards. It also includes a rpm window switch.

I guess this is it for this installment. All there is left is to wire it and do the motor. It needs some valve springs and a quick inspection of all the parts. The top end and pan need to come off. Maybe I can get it all done this weekend. Check back in a few for the completion of "Red."
