Dyna ignition, after market top and bottom fork braces

In 1978 BMW added the snow flake mags and improved shifter mechanism. This is the ONLY year an S model came with triple disc brakes, after 78 a rear drum was used, make the S model the top of the line with triple discs. Front and rear storage trays, Dyna electronic points and coils. Includes a matching color Corbin 2 up seat. San Jose triple tree upper brace-installed, Telefix lower fork brace-installed Gas tank internal cleaned and sealed. Twist the throttle, hit the start button and the bike starts every time. 
Here are the flaws, speedo needle fell off (the speedo worked fine before), the push rod seals could use changing. Bike has been stored in my heated basement since 2004. So expect some gaskets may dry out and drip fluid until they swell up.
