    Default 93 888 refurb/restoration

    Greetings everyone. I've been a member since 2014 when I was fortunate enough to find a 93 888 for sale while at the Barber Vintage Festival. After picking up the bike in Jan 2015, I enjoyed it and put on around 700 miles. Other projects got in the way of riding (selling house, buying new house and all the projects that come along with that) and the bike sat. After getting the new garage somewhat organized, it was time to tear into the bike for a refurb/mild restoration.

    The frame was dull and stained from fuel overflow The forks were in need of servicing and the bodywork needed some love.

    After having the bike broken apart, the frame and subframe was dropped off for powdercoat. After weeks of searching for a powder color that matched, I came across this color called "Desmo" from prismatic powders. A free sample was ordered and it appeared to be a spot on match.

    Once the frame and subframe were coated, it was time to start some resassembly. The motor was degreased/cleaned up and new belts installed.

    The forks were taken apart/thoroughly cleaned along with the front rotors. The rotors were disassembled and centers along with fork tubes were taken to the anodizers for a fresh coat of gold.

    The wheels were given a thorough cleaning with the clay bar, polish and coat of carnuba wax.

    As of now, the engine is back in the frame along with the rear swinger, rear wheel, shock hoop and rocker. I also noticed the previous owner must have installed a corse style rocker. The ohlins rear shock will go out to Ken Hall for service/rebuild/refresh. I am waiting on some seal drivers to reassemble the front forks along with the fluid.

    Below are a bunch of pictures during the tear down and reassembly up until now. Looking to get this baby wrapped up in the next couple of weeks so I can focus my attention on my 2001 996 I recently picked up.

    As always, I am astonished at the amount of knowledge on this board and any info/insight/advice is ALWAYS appreciated. Thanks guys and enjoy the pictures.

    Looks great... love the SPO version... (over the EU Strada looks)

    Fork legs look, satin mat finish... on purpose or just the way they came out ?

    The majority of the fork legs are 2024 aluminum while the bottom part/piece is 6061. Even after stripping/polishing, the 2024 takes on a satin finish where as the 6061 is brighter.

    One problem I have run into (having my own anodizing set-up) is that anodizers have to strip the old anodizing before the part can be re-anodized. I strip in Sodium Hydroxide (lye) which renders the part a matt/satin. (there are other chemicals for stripping) If anodized in that condition it will come out matt/satin. The only way around it is to re-polish the part after stripping and before anodizing. This can be done either mechqnically (buffing) or chemical/electro polishing. I opted not to set that "electro/chemical polishing" step up as the chemicals are really nasty. Most anodizers do not have polishing capabilities.

    Correct me if I'm wrong but I believe that rocker is OEM on a SPO, along with the Ohlins shock.

    Hi Marvin/jsedacca..

    Sounds like the two of you "are it" to make the ABC... Tread on ANODIZING and ALU grades ... incl Stripping, Polishing, Dyes,....and other tricks of that trade... seem streight forward , yet may tricks and issues to take into considerations it sounds like... i have a bunch of parts under consideration for treatment... i guess it's just to get started ..

    The anodizer I used does electro polishing but said it would not have made any difference with the 2024 aluminum. The only characteristic it would have changed would be the "machine" marks on the fork tubes would be gone and smooth.

    Interesting ! I have never done 2024 (all of my 2024 is Alclad aircraft alum. ) I have only done 6061 and 7075.


    P.S. were they matt to start with?
