Engine Work Continues

As we are readying for the big cannonball endurance run we are preparing the engine we will be using (referred to #2). Here are some pics of various components:

This is another flywheel set we are taking apart.

We will use this piston as a spare. It’s in great shape.

80 ft/lbs breakaway torque in crankpin nut.

Event motor flywheel and rod.

This cylinder had an extra hole on the top. Plugged it and we will use as a spare cylinder.

Lastly the drain plug hole was damaged. Welded up and functional again.

That’s it for now.

More Engine Work

I know you have all seen the EX running around. In the bike right now is what we are calling Engine 1. This was a motor we basically tore down, cleaned up, and put back together. We wanted to prove our theories on how the engine and ignition performed. So I have about 40 miles on the Engine 1. In the meantime we are working on Engine 2, the event Motor.

The picture above is showing the new belt tension pivot stud that was made. It is longer for an external support plate (shown in an earlier post). Below is the inside fastener and special tool.

One of the spare engines had a cylinder with a busted up base. So we are trying to save it by first removing the old base.

Next will be to press in a new sleeve and machine and weld a new base.

Should have the Engine 2 event engine installed soon. Then some 100-200 mile days await me in July.

Lots done today!

A cold raining morning in Milwaukee. So I started out with lacing up a new front rim.

Then moved on to an improved belt tension lever support. The stock support is a 3/8″ stud. We wanted to provide more support at the outer edge of that stud. Here’s what we came up with.

Next was to install and wire in an ignition booster to diminish the amperage flowing through the points. After install bike ran excellent. A noticeable difference.

Next was to install the newly modified pocket with a titanium valve. We decided to cut the valve and seat to a normal 45 degree angle, rather than the OEM 90 degree seat.

Also will play with spring tensions later, but now have a selection to conduct some comparisons.

After new intake bike sounds wonderful!

And all this done by 10:00 am!!
