CB750 K5 Dilemma

<< < (3/3)

Rozabikes Tim:
Ive been thinking about this process. Is it feasible to build the whole motor up as a shell with no "inards", blank all ports and openings off. Then process as a whole? Obvioulsy careful cleaning there after but I would imagine the liklihood of media in oil ways lessened.

I am sure I will be shot down by you clever people out there but seems to make sense to me....

Brett72:
The medium used is a soft silicone apparently and they are aware about the oil ways

Same as I did on my CB350K1 & Cb250K0's..I pressurised at a few PSI through the top breather and checked for leaks with soapy water before bead blasting....... blasted down with airline afterwards..washed down with acetone and then blasted again with airline. I just used gaskets coated with white grease and bit's of epoxy-glass circuit boards backed with rubber sheet .. old oil-seals with holes blocked off with bolts & washers/hot melt adhesive on the smaller ones.
