Oh Crap...

I knew one of you guys would notice that.

A good friend machined the steering stop for the frame, I marked the left and right with a center punch, so he could braze the new part on the neck. I dunno if it moved while getting brazed, or i marked it wrong, but it ended up a little off center.

Jeeeezze tough crowd:laugh:

Good eye!! Thanks for the compliment.

ooops maybe you meant the "fat" side, oh crap I have now exposed a mistake that could have remained hidden therby making myself look silly!!

Ok the fat side is an experiment of sorts. I am thinking about putting one of those really short GSXR steering stabilizers on, there is a 1/4-20 tapped hole on the side.

He he :laugh: I just don't quite have that one figured out yet.

Here's what I did on my 900. You'll probably have to weld a tab on your triple tree.

Yes the fat side. I hope u can figure that 1 out too. The stabilizer will be a nice touch.
I am glad i used rattle can paint on my bike for this very reason. it's to hard to get everything perfect the first go round.
I will be making some of these mods myself before i do the final paint job. Is there any tips on witch stabilizer to buy? Thanks for sharing your ideas. You too Doug.

Could be interesting...could see if we could put it on display at the Honda tent with the other custom bikes :side: . Maybe able to convince them that it shows the abuse it has taken and keep running.

Well my good buddie Ed the toolmaker let me use his lathe today, I machined up a slick set of bushings for the CR rear brake caliper (carrier), centering it on the axle and the diameter of the rear rotor. Two bushings that sandwich the carrier, and hold the rear wheel in the proper alignment to the countersprocket, and centered on the steering head.

Camera batteries are dead, soon as it's charged I'll post a photo.

If you are reading this, and have a project you have not posted, I encourage you to post it. I find myself thinking "hey it's been a week since I posted any new work". So you get busy on something. Kinda motovates you on the timeline.:P

Allright!!!

Lots of thinking and cyperhin went into the front and rear wheel alignment. Finally completed.

The CR 450 Caliper comes with a carrier, which has a giant hole in it for the dirt bike axle. So bushings are in order. I needed 1.330" spacing to rear wheel from swingarm and had to get the caliper centered on the rotor.

Solution: a two piece flange/ bushing that holds the caliper in the center of the rotor, and center of the axle.

Ahhhhhh let the machining begin!! So nice to make chips again.


Rather than bore you with yadda yadda technical writn jargon, I tried to graphicalize/ duct tape this here sicheeasion.:unsure:

Ok I struggled to figure a way through this issue, then decided to cut a section out of the frame. You have to cut deep, Made me nervous, you gotta cut the relief to the depth you need then deeper for the plate thickness.

ARRHHHHHGHHHH!!! I saw the guts, and almost vomit myself, it was horrid!! We made it through the surgery, I did not faint.

The cypherin was done a while ago, so i dont remember the exact width of the 630 O ring chain, seems like it was just under 1 1/8", I just remembered I need some clearnace for Chain flopperamagicness.

Another view.

Look at the swingarm bushing, we cut this whole sheet metal section out to align and put in the new swingarm bushings to fit the ZRX set up.

The tire clearance was easier, I used to go to the track in Seattle and Spokane with Racers from Wenatchee, so they helped me find the size. We knew the desired width, so we just started looking at all the bikes and measuring the total width till we found what was needed.

180/55 17 cleared the chain.

Hmmm... now you have me looking at the bottom side of the chain clearance I just remember that was not an issue. You would think it too would need clearance but seems like it did not.:S
