92 KX500 Land Speed Record Attempt Production Class

<< < (11/11)

Brute:
Looking good! When is the next attempt?

Rebuilt one of the 2.5 Mercury V-6 2 stroke outboards fairly recently. Fractured roller bearings on a solid crank. Awesome stuff! Makes me wonder what would it have been like if development had continued with them?

sandblaster:
Sorry it took me so long to reply... I have not been visiting very regular  :cry:
Bonneville will be the last weekend in August 2023.
Providing the weather is good  :-o
We are done this year for testing.
On our last test date I stripped a head stud  :-o :-o :-o
I shipped it off to Tom Morgan Racing to have some cracks welded in the exhaust port, get it re-plated, and replace all the studs with CR500R studs.

Tom has finished my cylinder and it is being shipped this week so I should have it soon.
The lower end has all the ceramic bearings installed and is buttoned up excluding the top end.
I need to remove the existing bottom end and get the new one installed.
We have about 7 months left for prepping.
But all I can do is break it in and get it ready for sometime late this spring.
After break in we will go to 4200 ft, same as Bonneville, jet it, and run it and see where we are at.
If we can top 125.031 then we are ready.
If not I'll try my latest cylinder which has a few changes that I want to try anyway  8-)
Nothing major but everything adds up.

Your right, so many companies gave up on Two strokes... Where would our KX 2T's be if the manufactures put a small fraction of money into them that they did on the 4T's.. Out of my garage I have made significant improvements... Obviously I feel that they left a lot on the table for improvements..

Brute:
Walter Kaaden developed most of the improvements that are still in use in todays 2 strokes out of a shop that 'may' not have had the tools you have access to!
I seldom visit any of the sites I was pretty active on a few years ago. A move, retiring, just life in general keeps me busy. I have no other 2 strokes other than my boat and yard equipment at this point.
Not sure about taking on more projects than I have sitting around waiting to be finished, though I keep looking at bike projects. My shop is not done, so the only power when I need some is running a 100' extension cord from outside. It is a bit limited. I hope to have that corrected fairly soon, but it is hard to say.
Best of luck on the speed tests!

sandblaster:
Thanks Brute.
The KX500 you sold me is going to get some love in the near future  8-)

sandblaster:
Well... Another year of testing done and Bonneville is a bust.
It rained less than a week before our event and it's all over.
Oh well...
There is always next year  8-)
Here is what 500 miles of land speed testing looks like on a KX500
