Hmmm, I cant see more output voltage blowing the base gasket.

The road is about 500 metres long I guess and is bitumen, with a dirt track off the end.

My mate who I asked to go for the test rides is a capable rider, whereas I am a numpty.

We did about 3 up and back each on the stock CDI to warm the bike up, and see if we could find brakes.

Then we videoed proto 1 and there seemed like an improvement over stock based on the amount of time the front wheel was on the ground. Which mainly was in 4th gear and 5th gear.

Then we swapped proto 2 in and did the same. Tom reckoned it seemed to have a better spread but not as much peak, but the bike seemed to be running fine.

Then we swapped the stock one back and after a couple of laps, things started to go pear shaped. It wasn’t revving out as well and seemed to fart a bit near over rev. This is when we discovered the oil under the cylinder, so I think that the testing was valid, but it is all seat of the pants stuff.

What do people recommend for compressing video? Or just upload it to youtube?

Just upload to YouTube.  As long as it's not over 10 minutes, I don't think it's a problem.

Okay Pete, unless you want to have another go testing, I guess we'll use the proto #1 configuration.

Great stuff Fred, I cant pick them apart, although I think your test rider was pushing it a bit more, pace wise, on CDI2.

That bike is going well.

Thanks for the work.

Yeah nah she is rooted now mate. Need a base gasket I reckon, but I will measure it up while it is apart. Still have heaps of compression and it still pulls like a 14 year old with a stack of stick books.

Thanks for the great videos, Fred.  I certainly can't tell which one is better, although I agree with Harko, the bike seems to be going faster with CDI2.  CDI2 has circuit modifications that produce a cleaner spark discharge, with a little more voltage.  Sure wish I had an engine dynamometer, then I could really tune these things up.
