Hi,
yes finally, I decide to put a shower TB on the D4. It's not the easiest thing but I found it smart
So I have a little few work : modify the frame and adapt the TB for 916 SP heads.
Valve covers I found are around 100$ so I continue to look for. I would be lucky...
For spacers, I wasn't aware about but, in fact, that's normal.
They are spacers between TB and valve covers? What size are they? I may be interested in yours...
I think it's one of the multiple surprises I'll have....
