The good:
I had a great time meeting new people and riding on sand again (it's been 20 years).
EZ did a great job snagging 4 camp sited all together and he did the leg work figuring out our options.
He didn't get a big ass shade tree but all in all he did a good job (the place was butt full).
I got a kick meeting Chris and dbloud.
And Stix provided entertainment wrenching on his Pilot most the weekend (Or we entertained ourselves ragging him).
I had an interesting discussion with Adnoh about setting up a piston.
He was explaining the process to measure the rod free play and the angle of the cylinder to the crank axis.
Then using this information in deciding the clearance from the piston to the cylinder.
It occurs to me that this is the process we use in our CAD system to create tolerance dimensions to make sure parts fit correctly with production variation.
Interesting discussion that I'm sure I will put to use soon.
When I took my family for the first time to a POOA ride my wife asked me if I met these people on line.
Yes.
So how do you know they are not going to murder us and steel our Pilot?
Now its a tradition, first question after I meet a new group - did they murder you yet?
I have ridden with the east coast guys at the old POOA east coast jam.
I have done Badlands in Attica Indiana with the mid west crew (hey when is the next ride?).
Now I can say I have ridden with the rednecks in OK.
The Bad:
Some how a few weeks ago when I started thinking I wanted to make this trip it sounded all good.
At the time Hoser was giving reports on his Big West Trip 2014.
Sitting at my desk I wanted a to do something.
Call it my small west trip.
I spent 3 days total driving 1000 miles each way to ride for 3 days.
On the way out I started to wonder if I was an idiot (probably am).
After the fact I can say it was worth it.
The ugly:
All was not peaches and cream.
On Saturday evening we went out for a ride but 5 minuets in to it while climbing a small dune it sounded like there was a box of rocks in my Engine.
I turned down hill and coasted to the bottom,
Engine died.
A quick inspection showed the crank had a definite looseness, rotating the driven clutch back and forth there was a clunking.
And very little compression.
My impression is the big end rod bearing is gone.
Ez gave me a tow back to camp then offered me a ride in the Wildcat.
Thanks and thanks.
I want to do a pressure test before I open the Engine up.
There are several ideas as to what happened.
I was traveling light, towing the small trailer with the pilot (mini-van with a small p) so I did not take much gas with me.
So I purchased gas there.
The Engine let go on the first ride with that gas.
I still want to check the alcohol content of the gas, it may have upset the jetting or created predetonation (I wouldn't know what it sounds like in a 2 stroke).
Or Adnoh suggested the piston may have separated.
There is a small bead of something caught in the spark plug.
Looks like a hot shard of aluminum was bouncing around in there.
He has some great pictures of what this looks like in his Engine rebuild tread.
The predetonation could be a contributing factor to this.
My favorite theory is the big end bearing seized.
I had thought the driven was acting funny on the ride prior.
My impression was it was not back shifting as fast as it should.
The Engine would bog on the longer up hill sections.
Also on this run I was wide open most of the time just trying to keep up.
This may have been the warning that I was too dumb to listen too.
I did take a quick look last night with the bore scope.
The top of the piston looks complete, no hole.
The surface looks covered with something, I cant tell if it is pock marks from spalling (predetonation) or chunks for stuff embedded in the aluminum.
Looking up the exhaust port the skirt is intact on the exhaust side.
The cylinder wall shows damage above the ports, like something got caught half in half out when the piston swept by.
If I have time I will try to take some pictures.
