On 5-11-18 Jason and I loaded the bike up and took it to one of the dyno's we already had numbers from.
Remember, we tested this bike before the turbo crank on two separate dyno's.
We did that because we wanted verifiable evidence one way or the other that this mod works, or it does not work.

Remember, we rebuilt the bottom end only.
The top end is the same worn out nasty dirty top end.
All we did was rinse it out and dropped it back on, carbon and all
It's not how we normally build engines but we had to keep the test as accurate as possible under the circumstances we are working with.

As you can imagine we were very nervous.
But let me tell you this, after run no. 1 it was clear we had a winner....
We gained a verifiable 15% over a broad range of the RPM... 15%!!!!!
Here is a graph showing our initial results..

We have a little jetting to dial in.
A bit on the needle and one step down on the main and we should be close.
I am not showing HP numbers as those don't mean as much as you might think.
Later this next week we will be taking the bike to the second dyno, which is newer and will show the entire RPM range.
I can't wait to see what it says.
But here is the deal, don't run out and buy a Turbo crank just yet....
Let's see what the second dyno says...
Next up I will take my good running all stock KX500 and run it on both dyno's.
I will take it home and replace the crank with a turbo crank and try it again.
If we get similar results I will be very happy but remember, the KX500 does not react to crank mods like the smaller cc's do.
But for now, we are going to rebuild the top end and start trying different combo's to see what the upper limit it for a broad power out put that will be guaranteed to put a smile on your face
