#2 Raceknuckle

OK. S&S KN93. As some of the parts will be modified, polished, ported, flowed etc. etc. the motor was disassembled first. As it turns out this was a brilliant idea because a piece of debris was found as the cover and gears were removed. Remember, this is a new, unused motor!

Where does that piece come from? As it turned out, the piece was missing from one of the tappet blocks and first guess how that could have happened was that the tappet was slightly twisted upon assembly so the roller broke off the edge.

However this issue was solved quickly with the help of the german distributor by replacing the broken block with a new one. One other thing to mention is that you don't expect a lot of scratches as shown below when opening a new motor:

Just not to forget, motor and assembly work on this project will be done by Michael Schneider. Check out his website: Schneider Performance

#1 Raceknuckle

Well, how to start? This story is about building a new bike, based on a fake knucklehead that I bought some years ago. It sat unused in the garage for some time and after spending some time thinking about if I should burn it or use it for something fancy I decided to start a new project with it.

The good thing about it is the fact that it has a german license stating the year built is 1947 which in turn means that higher exhaust sound levels are possible, no turn lights and mirror are needed. I decided to keep only the frame and add some new parts:

Old fender is removed and a new, light one made of aluminum is fitted as well as a Mesinger racing seat. However the Mesinger doesn't fit right, looks good from side view but seen from the top it is too wide and disturbes the frames line:

Regarding the motor I'd always liked the S&S KN93 Knucklehead so this one will make it into the bike:

It will be equipped with a Weber two-throat DCOE40. The motor will be tuned a little bit, so in preparation of the tasks to come and to decide if the S&S cam is to be used the valve lift is measured:

Most parts of the motor are getting polished, heads and connecting rods for example:

Finally, to call a spade a spade I'll name it "Raceknuckle"...
