Got some promising answers coming from Yoshi.



Hey Al-

I will get Ryan Cox to answer your engine questions as soon as he gets back. He’s on a cruise to Mexico right now. We kept the compression pretty low this year though. We didn’t have that much time for durability testing so we stayed pretty conservative.

During the off-season we are going to be doing some pretty intensive performance development work with the engine. We will keep everyone updated as the process moves along.

On the transmissions- I forgot to mention the other day, but all of our race transmissions are Ceradized at Hinson’s before they are ever raced. This is something that we always do on race engines. Hinson does this service for the general public as well, I think the cost is around 200 bucks(?) It really bullet proofs gears. I recommend any serious racer to have this done. We offer it as an option for our customer race engines. Frequently we also use the REM Isotropic Surface Finishing (ISF) treatment on all internal engine parts. This is part of our blueprinting process. These steps also reduce friction from the rotating mass making the engines feel “freer” and reducing heat.

One thing for sure- if you are building a serious engine for your LT-R (or any bike) I would definitely Ceradize the gears.

The little shift saver link you sent looks great. Hinson makes ours and also sells them to the general public. I will try and get him to send us a link or the actual prices and part numbers of these things.

Brant Russell, Yosh

Thanks elks good post think I'll be giving hinson a call on monday better safe than sorry.

GREAT info Al...you trying to win the cowbell award for a second month?...

 

[AL Elks]

Heck no. I fugure the more stuff I point out the more stuff people will try and then I can pick and choose what I want to do based on their results.

NOT!

I just like researching this bike.

 

[SandJunkie]

Hmmm...sounds like a slow day at the post office... :lol:

 

[LTR450_#67]

Haha. Its cool that Yoshimura is interacting with the public owners on these awesome machines. They kept the compression kinda low and they were still kickin some tail!!!

So I go to GOOGLE and type in the word "Ceradized". and My search did not recieve any results. I didnt know that could happen. :blink:


So the big question is what is Ceradized.

 

[AL Elks]

Yep, they mis-spelled it. It's "Sheradize".

Sheradize

Lovatt's Sheradize specialty treatment for steel improves hardness in heat-treated steels and is currently being applied to all steels and cast iron. The Sheradize treatment is a unique process which cannot be compared to any other steel treatment. The treatment uses unique circuitry and a proprietary cold electrolyte which creates a molecular structural change. The new surface causes no dimensional change, the treatment is all penetration. There is no warpage since the treatment is done at sub freezing temperatures. Change in color after treatment is very slight from the original metal, in most alloys. Also, certain alloys of Sheradized steel have proven extremely resistant to corrosive attacks by sea water. The U.S. Navy has used both Sheradized steel and Akadized aluminum parts

LOL I love google

Here's the rest from that page:



Hardness:
On the Rockwell C scale. Non heat treated steel generally increase 4-6 points. Heat treated steel generally increases 10-20 points.

Weldability:
Sheradize provides a method by which one can normalize or stress relieve a part after machining, grinding or welding and be assured of absolutely no distortion.

Density:
Density of the molecular structure near the surface of the treated part is increased.

Corrosion Resistance:
Offers good corrosion resistance to some steels. Significant improvement has been reported for treated versus untreated parts.

Lubricity:
The surface RMS of the treated part is normally improved by up to 50% increasing lubricity characteristics, while providing a tough and durable surface

Embrittlement:
The Sheradize treatment removes gaseous interstitial impurities from the treated area. Fatigue life of the component may be greatly improved through the removal of residual stresses.

Mechanical Properties:
The life of cutting tools normally is extended many times over untreated parts, or in some cases made it possible to cut with tools that prior to treatment would not even make a minor cut in soft aluminum stock. After the treatment there is significant increase in resistance to galling.

 

[SandJunkie]

Yes but can you use it correctly in a sentence?...

 

[LTR450_#67]

Wow that hardening process is pretty interesting. Hinson does it for about $200... hmmmm...maybe when I get a 2008 LTR I'll get it done.

"I had to uh, Sheradize my cookies with my friend at lunch since he forgot his." ha ha wow im stupid

 

[nate449]

Is sheradizing like putting your parts in a cryo freeze then bringing them back to normal temps? Or is it something completely different?

 

[SandJunkie]

Or..."Are you Sheradize before I goes to heaven"?...

 

[alx]

anyone else think this as well ???

or am i wierd :blink:

"she Sheradize her hair, which led to sleeping with under-aged boys"

Yep, Sounds like the same thing to me.

 

[AL Elks]

Or could it be:

Come on man I can't play craps with just one dice!
Sharadize with a brother!
