The flywheeles are about ready to get balanced. There is an original flywheele on the rightside of the picture to show the change in strocke. The strocke is now 4 1/4 inch. Now its time to start change the engine block to get this to work........... I will keep uppdaiting as I make progress.
The flywheele is redy welded. It took me about two days to get the parts welded with interpass and preheating temperatures and the slow down heating to avoid any cracks or tension in the flywheele. Ready for the mill and lathe.
My friend Hannu asked me if I can modify his flywheele, to make a longer strocke to it. Yeah why not, haven´t newer done this so I made it sort of an chalenge to my self. I grinded the old hole for the pin so it could be tig welded, and the part is preheated befor welding.
Closeup of the work made on the bike. I like to use old parts and that is made in the shop. I dont like to order parts from Taiwan Ted........ you know the expensive sh*t that dosn´t fit or work
