Well done Robert, I wish I had those well spend spring days.
This manifold was available for little money. so I went for this one. Its new old stock. Doesn’t look that it was ever used.I noticed you installed your wrapped "spaghetti" manifold.
Question; Why a 4-1 instead of a 4-2-1?
Okay, your R4 fanaticism already costs a shitload of money anyway
I've only seen 4-1 systems for a R4.
I understand that a 4-1 system is for high refs and thus performance and race purposes as the 4-2-1 system for low and mid range refs thus road performance. I've allready done my calculus on a stainless 4-2-1 as I've not yet seen a 4-2-1 on the market.
Any experience yet with your 4-1?
