Some of you may remember Brute's old KX500 8-)

Here is Jason blowing out the cob webs.
It hadn't been started in a year and a half.

If your ever down this way, you can always take her for a rip...
Just let me know in advance that you are coming so I can make sure that she is ready to go.
We have so many mods that we are wanting to do, then dyno, it crazy.
Luckily we have a local shop with a dyno and the owner loves 2T's so we get some free time... It's hard not to abuse it.
I want to go there every day with something new :-D
I need my own dyno 8-)
Once the Turbo Crank is tested, I have a top end that I am building for the MXA bike build off against Adam Millar that will go on this bike.
It should prove to be very, very interesting :evil:

Post by: Brute on May 17, 2018, 07:06:08 PM: Quite a generous offer! Probably will not take you up on it but may stop by just to say "Hi!" and see some of your projects if I get in the area. I will look forward to hearing how the mods work out.

It's all back together and the main jetting is dialed in.
I need another needle for it but should have it early next week and then on to the dyno :-o

In the KX500 we lost 7HP :-o :-o :-o

We since have learned a few things and applied that to version 2...

OK... Turbo Crank revision 2 is done... :lol:

Seriously though... Revision 2 is done and we just need to put it in a bike and dyno it...

as you can see, the cylinder has not been carved upon..
Just lowered..
In the next two weeks I hope to have it finished, broke in, then dyno'd..

Post by: sandblaster on June 05, 2020, 07:17:45 AM: I always try to get something done on my project bikes every day.
But yesterday I was feeling pretty unmotivated.
So I went out to the shop about 8pm and installed the governor cover and called it good :-o

As you can see, this is not a polished fancy pants build.
Right now I'm in the testing and tuning stage.
Once I dial in this engine, then I will take it apart and apply all the glitter and makeup :mrgreen:

Post by: sandblaster on June 05, 2020, 02:49:39 PM: I was getting ready to put the carb back on when it occurred to me that the jet block o=ring gasket has never been replaced :?
So, I can't let that stand.
It's good thing I checked it s it was beginning to fall apart.
See that little chunk missing?
It is suppose to be missing..
But, the gasket is starting to fray round it's outside edges.
The bike was still running good but it was just a matter of time...

Post by: sandblaster on June 06, 2020, 07:24:17 AM: And those that know me realize that I will never build a KX500 engine without dissembling the air box and cleaning it, then sealing it with some Ultra Black RTV silicone..

Post by: sandblaster on July 14, 2020, 02:19:36 PM: Tests at the lower port timing is complete.
Now I have it set up to stock port timing specs.
Can't wait to see how she will do.
