Ok, I have about 3 months to get all the testing and tuning done before heading out to Bonneville.
Time to get serious.
This all came back from Tom Morgan last week and is ready for my secondary engine.
I prepped the crank.
Doug Haas made my stuffers for the pin and the crank.
Tom Morgan, assembled and balanced it.
I did the port work and made the calculations for the desired port timing.
Tom then plated the cylinder to the piston size and a little extra clearance 8-)

Wow! It's been a while since I updated this thread.
We were shooting for 2021 to break the record but since we were 2 mph short we figured there was no sense in going. :oops:

Further, Stewart Rouse who built the engine that holds the current record died of Covid :cry: :cry: :cry:
Stewart gave me a lot of ideas on how he did it.
He would tell me technical information that took me a while to digest at times.
But the deeper I got into this quest the more I knew that Stewart knew exactly what he was talking about.
I'm going to miss our conversations.

But, not all is lost.
We will attempt to break the record in 2022.
The biggest failure was not allowing ourselves enough testing time.
We did a bunch of dyno work but then discovered that dyno work is only a small part of the equation.
Testing on the street is they key to success.

Due to work schedules I am building a back up bike so that we can double up our testing times.
And since the dyno work is done our focus will be on street testing.

I'm close to having the back up bike ready to go..

The bike in the front is the backup bike or LSBB.
The bike further away is known as LSB.

LSB is ready for another test as soon as the weather clears up.
LSBB needs a few things :-)

Bam!!! Unofficially Jason Tanner at JT Engine Works just went faster a Production 500cc single cylinder than anyone on the planet :o
With our Rev 3 top end we beat our best run by approx 4 miles an hour.
That said, it is unofficial and I believe that we still need to fine tune it.
What is possible?
I don't know but we will find out.
How fast did he go?
I'm not talking until we take the record at Bonneville...
