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

I took a long weekend and traveled south to meet up with my old man for some tard action.
When I arrived, I unloaded my bike and started it up.
It wound up to the moon.
I was grabbing the kill switch and freaking out.... but finally got it stopped.
So I checked it out and could not find anything wrong.
After I got it shut down and checked it out I tried to start it again.
Nothing... No spark...
Tried what I could but nothing worked
I guess thats what I get for using 20 year old electronics :D
So, I have been wanting to install my MZB ignition...
I guess this will be the week.

Now for a quick recap.
I did the water pump impeller clearance mod.
I cleaned up all the water passages.
Cleaned up oil passages in the cases.
I have a re-cut head.
Chinese Rads.
Stock port timing.
Cleaned up cylinder transfers, ports, and bridges.
Balanced crank.
Wossner windowed piston.
VF2 Reed with modded boot.
41mm carb jetted a bit rich at the moment.
Running 1 qt of distilled waterper 2 oz of Royal Purple's Purple Ice (Bought it at Napa).
MZB ignition with a flywheel that is 1lb lighter then stock.
My bike has never ran so cool and with so much smooth power.
Time to start another build with some advanced port timing

According to gearing commander.com I should be able to hit 88 mph in 4th at 8500 rpms.
I can hit 90 if I flog it hard. Now to find some place I can do it in 5th. Will I hit 105?
I'll need to hit 8500 RPM's to do it.
