 hand engraved magneto timing chest for the bitch

 New bushes pressed in and reamed by Baz

Be careful with the pinion shaft bush if you buy a timing chest cover. This was fitted with an early type (pre 72 side oiler) and later model pinion shafts are end oilers (no side oil hole in bush required).

Exhaust Leak?

Evo gasket part # 65324-83 - cut in half

tip from Hawg ryder @shovelhead.us

 and slip over your original gasket

there will be a gap but it seals

- but not for me, not quite, and I tried it without the gasket

I also tried some special 'racing' exhaust gasket sealant, 

but that didnt work for me, it seemed to melt when hot

but I did try this 'high temp' oven sealant, Otto Seal S17

leave for 24hrs to cure

It worked for me.

My rear exhaust port has always been a problem since the rebuild

The port had been welded and the new style James gasket would not fit. So a fair bit of relieving had to be done with a very small file.

Coupled with an an exhaust flange that was not quite square to the head meant the gasket didn't seal on the opposite side to the mounting stud.

Another stupid Harley design, although I fitted studs on the rebuild, god help you if using a bolt which strips the threads in the head. Ask me how I know...
