Project "I needed to clean the air filter so I blew the motor"

(1/73) > >>

USMC 500:
In case you haven't heard by now, Project "I was only gonna clean the air filter" came to a sudden stop during our Dove Springs California ride (http://www.kxriders.com/forums/index.php/topic,11645.msg92808.html#msg92808) this past weekend.  Absolutly nothing wrong with the way the motor was built......In this case it was all my error :oops:......

I began the heat cycles after the first build last year in early June so I got a full year of riding out of the motor.....I guar·an·tee  that this motor would have gone much longer had I not brain farted so bad.

For those of you not familiar with my original build you can view it here.....http://www.kxriders.com/forums/index.php/topic,8890.msg69112.html#msg69112

Fortunatly for me my engine builder and half brother Motorrad was there.......bet you guys didn't know Dave and I were related :wink:.

So we pulled the motor right then and there so that "The Great Motorradini" could take it home with him and fix my shame......

This thread will be a combination of pictures and "one liners" from Motorrad with myself filling in the details........

And as far as the title goes, since the first build was started by my cleaning of the air filter I figured that to clean the air filter I would need to start at the motor this time...... :lol:

So everyone keep your eyes on this thread.  I was asked if I wanted to keep this "hush, hush".......I am man enough to say that even though I am ashamed about this topic I am not embaressed.......My hope is that eveyone will learn through my experience of what can happen to even the best built motor........So pay attention, ask questions, enjoy and above all......LEARN MY LESSON INSTEAD OF YOUR OWN!!

USMC 500:
I thought I should be the one to post up the first picture........My once beautiful Wossner revealed upon removal of the jug.....

Ims Roll:
ohhhh poor k5 hope motorrad gets her back up an running like new again for you.

USMC 500:
OK so lesson #1......

I like my bikes looking good so I wash them after every ride.......not a good idea.  I think I'm gonna stick to wipe down's with a wet rag.....My head studs and cylider studs looked brand new when the motor was assembled....Look at them now.







Try not to make a habit of hosing your machinery down on a regular basis and when you do make sure you start it up and get everything nice and warm.

Next item........the benifits of polishing your combustion chamber.....here is mine after 1 year of riding and this is what it looks like after wiping it off with a rag.....no cleaners of any sort were used.....only a rag.

"Thou shalt not run 2 sizes too small main in a 41mm carb on a K5 wide open down fire road with s**tty oil."     - ˭M˭  3:16
