Project started October 2023,

 

The back and the top of the oiltank were templated, cut out and welded in. It still needs mounting points, oilline connections and a filler opening. And pressure testing ofcourse. More about all that later..


 
 
 
 
Because the bike has an electric starter it needs a fairly big battery. After a lot of headscratching we removed a piece of frametube under the seat so the battery could be mounted and removed.
This piece had to be removeable so we made some threaded plugs and Aad welded these in the piece of frametube that we had removed. On the frame itself we added some collars for the bolts to push against and using a steel bar with a piece of machined aluminium as a guide the mating surfaces were ground flat.

 
 
Now that the tube is bolted back in place the modification is almost invisible, but it will make life a lot easier not having to remove the oiltank to get the battery out.

 
 
 
Next time I will show the oiltank mounts, filler opening and oilcap we made. These pics are from a few weeks ago, we are actually quite a bit further along with the bike as I write this.
