Stone's CB450 project Tamara

[dcmspikes]

def tuned in for this. what part of central cal are you in? i head up to SLO area every once in awhile. rode my kz650 up there a few months back.

DYAMN!!!
Ti bolts.
That's got to be another grand, they are like fifty to a hundred bucks each 8)

 

[stonenck]

Talk about going all out on the engine
Love it man!

thanks pete!

I'm in fresno brotha, right on I love slo

ya they are pricey but not that bad

is that what those are? huh. where else are you saving weight in the motor?

I have the same cam in my 360 right now. It was just over $400 after shipping, but it also requires modified pistons and valve springs, so get ready to shell out for those as well. I'm still working on getting mine running but we'll see how much punch she packs after I have her tuned in.

I got everything sonrier! check my earlier posts, I hope shes a beast!

thats really it, I just love the machined look of ti

I thought Ti bolts and aluminum cases were a no-no?

I remember some airplane liability case where the threads on Ti bolts corroded really fast, the fasteners let go and everyone died. I believe its called intergrannular corrosion and the failure mode is a stress corrosion failure.

I remembered it because some race teams were using Ti wheel studs and aluminum lug nuts with the Ti wheel studs breaking, not the aluminum stripping.

I filed it away in my brain for when I would try to save weight.

Titanium is a fairly noble metal, and therefore pretty resistant to corrosion. However Ti and aluminum are pretty far apart on the anodic scale... so you will run the risk of galvanic corrosion on the aluminum, as the Ti is the nobler metal of the two. Most of the fastener manufacturers I use in my line of work (robotic automation. high speed machinery with low weight tooling) recommend against using Ti bolts for that reason.

You're pretty much limited to fastening to copper alloys, carbon steel, and titanium.

Although in the car tuner world, lots of people use Ti bolts in aluminum parts, and swear that anti-seize is all it takes to prevent the galvanic corrosion.

Both 5th gen fighters (F-22 and F-35) use Ti bolts into aluminum, CRS and Ti bathtub fittings, (I am a contract machinist for Lockheed Martin) they are using a coating to supposedly prevent galvanic corrosion. Most parts and panels using the Ti Fasteners are removed pretty frequently for corrosion checks. I still think its odd that they were willing to take the risk on running them...

So that's probably just part of the reason those things are so expensive to maintain.

Excuse my ignorance (and laziness for not wanting to google) but what are TI Bolts and why are they so friggin special?

Bolts made out of titanium. They're special because they're strong and very lightweight compared to steel.

OH! Ti like the elements table. That's a horse of a different color!

 

[stonenck]

i'm glad your comparing my project to fighter jets lol, we used ti on everything in our race dirtbikes forever, and am pretty sure its standard in all forms of motorcycle racing, and auto racing. its gonna be ok!

 

[flatcurve]

Honestly, I think you'll be fine if you use anti-seize. You wouldn't be the first person to use them.

I would just recommend staying away from using them in "high torque" situations like head bolts and such.

Did you end up milling the top of the cylinder casting or the bottom for the extra compression? Or the bottom of the rocker box?

exactly, i'll mill the top of the cylinder, go back in the thread pj explains what to do

 

[stonenck]

got my caps back from anodizing black

redwillis got the red ones, I'm kinda jealous

 

[atx360]

very cool...

 

[redwillissuperman]

just need to build a bike to put them on now.....
