Well it looks like there are 5 choices OEM, Hinson, Wiseco, Magnum, & Barnett. Now keep in mind i just ordered a Barnett Kevlar clutch discs. Im trying to build my bike for reliability over power and plan on racing some hare scrambles/ endurance race for fun. Looking at the descriptions from each company's web site and i dont know what to choose.
OEM is made of cast aluminum and is not coated with any sort of lubricity covering. There for i think it is easier to brake and will wear quicker. But it does come with the drive gear. $109.00
Hinson is made of T-6 7075 Billet aluminum which is one of the strongest billet aluminum. It is also *Akadize which is a protective coating that helps make it stronger and lubricity. It does not come with the drive gear but includes hardware to install. $239.00
Magnum is made from a solid block of aluminum but there is nothing stating the aluminum's rating. Also there is a "special" hard coating that is added to help lubricity. I did not find anything that states if it come with the drive gear or hardwear to install the drive gear. $140.00
Barnett AKA MSR clutch basket's are made of a machined aluminum **forge. Each finger has replaceable 3161 stainless steel inserts to protect fingers from wear and provides smoother action. It does come with all hardwear for the drive gear. $246.00
Wiseco clutch basket's are made from a **forged aluminum alloy. Each finger has relive cuts to reduce the weight. It is also coated with ***Teflon much like your cooking pans. The basket does come with hardware to mount the drive gear. $230.00
The oem is too cheap for me, and like i said im looking for reliability. The Magnum clutch basket is too secretive for me with their "special" coating and no name aluminum. Hell they dont even have a web site. Hinson sounds like a great clutch basket strong and great lubricity properties. I am very impressed with the material used in the Barnett/MRS clutch basket. It seems like it will be VERY strong and it has replaceable finger inserts so you dont need to replace the whole basket again! But the inserts also scare me, it seems like it could be another failure point within the clutch system. Wiseco Sounds like a great idea but i feel like the Teflon could be scratched off much like my pots and pans. Keeping the basket lubricated with new oil probably will prevent that but it still is a possibility.
What is your opinion with hinson,barnett/msr, and wiseco? your experience with either? has anyone replaced the finger inserts on the barnett/msr? how much are the inserts? Would you prefer *Akadize or *Forged? Has anyone had issues with the teflon scratching or wearing off?
*Akadize is a remarkable metal surface technology that vastly expands the usefulness of aluminum and its alloys. Akadize creates a permanent surface on the aluminum that is exceptionally hard, slippery and dense. It adds anti-corrosion, thermal resistance, and dielectric properties that are beyond the measure of conventionally-coated aluminum. The improved performance characteristics of Akadized aluminum make it the functional equal of more expensive and heavier metals. Indeed, in hundreds of applications, Akadize has surpassed performance challenges that were never before approached by aluminum. Akadize is an electrochemistry technology developed for use by NASA and aerospace programs. It utilizes unique circuitry and special additives to transform the molecular structure of the aluminum base. The new surface is half penetration and half buildup and becomes an integral, permanent part of the aluminum.
Akadized aluminum has been commended for its superb performance in the most demanding conditions. It has proven itself in space and undersea, in extremes of temperature and harsh environment.
**Forging is manufacturing process where metal is pressed, pounded or squeezed under great pressure into high strength parts known as forgings. The process is normally (but not always) performed hot by preheating the metal to a desired temperature before it is worked. It is important to note that the forging process is entirely different from the casting (or foundry) process, as metal used to make forged parts is never melted and poured (as in the casting process).
*** Teflon - Very few solid substances will permanently adhere to a Teflon® coating. Although tacky materials may show some adhesion, almost all substances release easily. The coefficient of friction of Teflon® is generally in the range of 0.05 to 0.20, depending on the load, sliding speed, and particular Teflon® coating used. Since surfaces coated with Teflon® coatings are both oleophobic and hydrophobic, they are not readily wetted. Cleanup is easier and more thorough—in many cases, surfaces are self-cleaning. Teflon® industrial coatings can operate continuously at temperatures up to 260°C/500°F.
