hi does anyone know how to plumb in the automatic choke on a fuel injeted r1?

Yep, the feed for it comes from the little pipe T'ing off the water pump inlet pipe (under the sprocket / gearbox output). That goes through the "choke" and the outlet goes under the throttle bodies back into the top of the engine if I recall correctly.

thanks chris, i noticed on the bike it had a t-piece running to top of rad , can i ignore this and connect it directly to choke like you said?

I suspect that T probably also bleeds back to the expansion tank, but Ive just plumbed mine as described above and its not caused a problem (I didnt have a T on my engine so didnt know at the time!)

that will do nicely, thanks alot!!
