Fort Worth Motorcycle Riders

New project:



Needed a tool for the castle nuts in the engine mounts:


I love CNC


Fits nicely.




Old motor


Out with the old


Checking compression and valve clearances on the new motor


Replacement motor installed.


Time to reconnect all the hoses and cables. Should take another day to finish.

CBRasaki? Cool green wheels.

My friend, I may need your help...do you work cheap?

cheap work is never cheap...
But yes, I do offer big discounts to club members.

Found what was causing the noise in the old engine.
Can anyone else see whats wrong in this picture of cylinders 1 and 2? Inlet side is up.


Now I have to strip out the crank to see if the bottom end has any interesting stories to tell

Dead Cyclinder ?

The cylinder is fine. it even has good compression. but when it starts up, this motor makes a whacking noise so loud it sounds like a hammer on a steel workbench.

Is it just the camera angle or is that cylinder worn way out of round?

I think I can see rings at the bottom left of the cylinder between the piston and cylinder wall and the top of the cylinder looks oblong on the right hand side.

Heres the issue. Notice the imprint in the top of the piston circled in red? The green circle is normal for comparison.
When a valve hits a piston something is seriously wrong. Apparently this motor had a recent valve adjust...

I was looking at all b that carbon.

Yep, me too. Hence, I'm not a mechanic and need professional help (on the bike, not the brain).

Man, every time you post something like this I get so jealous, I so want a CNC machine to make odd ball stuff.

We've got a full service toolroom where I work, but we're so friggin' busy trying to make money for the big corporation that we have no time for anything cool. We also have a very good 3D designer...and over 2000 dies and molds to keep him and the equipment all tied up.

FIELD TRIP!!!!!! That is awesome!

I know, it would have been so easy to machine a set of lowering links with one. Oh well, at least now if the link fails I can blame T-Rex Racing

my CNC mill is pretty small so is only good for little pieces. and it's only cost me about $5,000 so far. Considering how much I use it I get better value for money from it than i do from any of my other toys and motorcycles.

I am glad that when I get done with engines at work usually they dont have to work. That is awesome work.

Heres a timelapse of the entire project.

Very cool! Thank you for sharing!!

Awesome!
