what was the vibration comment at the end?  Is it noticeably better with the balanced crank?  Sounds wonderful.

Yeah, my buddy Jason who was on the bike and made that comment noticed it was smoother right away.
Right after that comment I started varying the throttle and it is noticeably smoother.
Hopefully the weather will be better tomorrow and I'll take it on a ride.... After a few more heat cycles.
Then, I'll change the oil, take it out, and wind the springs out of it  8-)

Sounds excellent! Makes me embarrassed that mine is still sitting on the lift.  :cry:

Took her out for a short ride this afternoon.
So far I couldn't be happier.
The power comes on quicker and the engine revs faster then I have ever felt.
I couldn't flog it because I'm still in the break in mode but I can already tell this is the best engine I have ever built for the KX500.
Having the crank balanced is a huge plus.
I wish a I had a vibrometer to tell you what was happening at what RPM but I don't.
Butt Dyno result says it vibrates half as much as the stock bike maybe less.
I use to start my bike, set it on the side stand and it would vibrate circles around my driveway.
Now it sits there and purrs... Oh yeah.
I hope to have it ready to blow the cobb webs out by Saturday afternoon.
More info will be coming as I start opening it up.

I use heat cycles with a non synthetic premix.
I vary the rpms but don't twist the throttle too hard.
After heat cycling 4 times or so I ride it gently at first and gradually gas it a bit harder and harder until my desert tank needs a refill.
Then I change the crank case oil, fill it up and pin it to win it.

Pinsonnault Racing.
So far I'm highly impressed.
I'll be sending another their way before long.
I have to get another engine ready for the AF project  8-)

I had to go to the bank.
I had to go to the DMV.
I had to go to the store.
I had to go to the post office...
It's amazing how many errands you have to do when your super moto is running and the weather is nice :-)

I took it out and rode it for about 50 miles city and hwy miles.
Combined with my previous rides I felt as though it is well broke it.
So I was at a favorite close to home mountain rd riding spot and I needed to pass some cars.
Dropped into 4th and wound it out, quick shift into 5th and pinned it WOT for a few seconds....
I was not disappointed in the least.
Now it's time to start playing with my next engine build with advanced port timing  :-o
The engine in my supermoto will end up in my AF build eventually...

Yesterday I took the Supermoto out for about a hour ride.
It was 95F out, don't know the humidity.
It was about 30% in town and about 70% windy hwy with a posted speed limit of 55 mph  :evil:
Since my last post I changed a few things on my bike.
I did a complete bottom end rebuild with a IMS pro rod that was rebuilt, welded, trued, and balanced.
The transfers, ports, and bridges were cleaned up.
The head has a squish change.
The port timing is stock.
The piston is a Wossner windowed piston.
I also have the Motorrad coolant passage clean ups and water pump impeller clearance mod.
I am also running Chinese Radiators.
So basically I'm running the factory engine that Kawasaki should have built excluding the exhaust port work that I couldn't do without re-plating the cylinder :D
It is definitely faster then stock and way smoother...
Also running 50/50 antifreeze
My running temps were as follows
Water after cooling 143-147F
Head temps 190-199F
So I'm definitely headed in the right direction.
I'll be trying some Royal Purple with distilled water later this week.
I'll note any changes I find 8-)
