GPz1100B2 – Engine Assembly

Engine Assembly

While assembling the frame has been reasonably straight forward, the engine work has dragged on mainly due to too many other projects. However this month (January 2015) has seen some renewed effort to rebuild the bike and have it on the road shortly.

Staring with the top case, I unwrapped it after it has been meticulously water blasted clean by Specialized Blasting Services.



Next, the top engine case getting fitted out with the crankshaft back in first. Basically its the exact reverse of the disassembly process. A new cam chain is fitted as well as a new crank seal. Main journal is not yet bolted down in this picture.



First the main bearing cap is installed, clutch and output shaft come next. A new oil seal for main oil gallery is fitted before bottom case goes on. In the bottom case the shift dogs live so these need to be slid into place.



The top and bottom end assembled minus the side covers. The gear change hardware is added. Still to install is the gear shifter and “transmission” cover.


Looking at the other side, Ignition case yet to be installed, clutch basket needs gasket and cover installed.


More photos to come! – I just need to upload photos off the camera and post them to the blog article. So check back later in February for an update.

  1. Awesome guide, Kinda helps alot to see how the engine is put together before one starts the disasembel. Maybe a little request when putting it back together. It would be awesome if there are torgue specs and little hints along the way 😀 Then it would just be complete 😀

  2. Good point 😀 still looking forward to see more 😀
