Help!!! Upper Pipe Mount Broke Again.
« on: January 01, 2005, 10:45:53 AM »
Guy's I need ya'lls help. I spent many hours this week rebuilding forks and rear shock , changing brake fluid, lub calbes, Gearbox fluid. Went riding for about 2 hours and that D*MN uper pipe mount broke again(The one on the frame) :cry: . The one just under the tank. Man it was 75' here and sunny perfect day for riding. I found one picture in the gallery of a mod. pipe mount. I would like to have more detailed picture of the mod. and what process you used. Thanks. I guess I will just wait unitl next weekend to ride.

Hughes;

I welded a pice a 1/6" thick mild steel to mine that was .500 wide,
and around 2.500 long.
I tryed tapping it to a 10-32, but it didn't hold.
So I had to use a nut, and lock washer on it.

Oh also, I put a .5 pice of rubber between the mount, and the pipe.
 :lol:

I will, but I'm a little beat up from to much partying last night.
So it will have to be a bit later.

I think some one has some pic's of that mod. in the gallerys.

Taking my bike to work with me in the morning and fixing that pipe mount. I think am going to use a 1/2 square stock and cut it out on one side to fit the shape of the bike frame. I think that the square stock will be the strongest thing to use(4 sides). I should be able to get pic.

The d**n mount is going to break for the rest of the bikes life. It's just going to happen. I have the same issue and it will NEVER go away. Once broken, it will not stop. I even cut the mount off another KX and welded it up from scratch and it still broke. The vibes just kill the weld and does not hold well. But, if you can keep it welded, let me know, I also am having trouble.

Mines been welded now for 3 good rides, with no sign of cracking.

I made mine thin, to take up some of the vibes!
I also put a .5 think pice of rubber between the pipe, and mount.

Lucky 4 me. I own a machine shop. And I can make all kinds of goodies.
If this wont work, then I may try to fab up a mount that will clamp all the
way arouund the frame.
We'll get it worked out!!!

Gowen;
What did you weld it with?
And what kind of wire did you use?

Machine,

I work for Yamaha Motor Corp. (Marine Division). I provide technical support to our factory team anglers. I have a moblie shop that I set up on site. You may be able to see it in my gallery(Yamaha trailer). I travel mostly in the south east and north east. I live a hour from our engineering factily and that was were I was repairing my bike. I wish I owned and knew how to operate a machine shop. I can't weld so I let the guy's in our machine shop fix may pipe mount. I have no pictures at this time. I did use the 1/2 square stock and cut out the top backside half to fit the frame and welded it. I did what you talked about. I placed a 1/8 slab of rubber between the bracket and the damper pipe mount. Next I through bolted with a 1/4 stainless bolt and lock nut.

Machine,

Hope to go to the local track(they have motocross and a 11 mile offroad track) this weekend and run the hell out of my bike. Maybe i'll get some riding pictures. The only thing that sucks about the older bikes is that the day may get cut short due to a failure. I need to get some time on the new pipe mount.

Gowen;
I hate to say, you are right!
I checked mine tonight, just to see that it had broke "AGAIN!!!" :twisted:

I don't have time to fab up some thing cool yet.
So I'm going to have to come up with some thing simple.
And if it works, I'll let you guys know!

Do all KX5's have this problem or do you guys have similar years or maybe older models? Seems like if it was a big problem then Kawi wouldve caught on to it and maybe corrected it on later models... I'm just curious to know for my own personal knowledge.
Rock it 'til the wheels fall off!
