Yamaha 66e fans might like this

Stick with the 66e cylinders, the 1300R's have no bottom-end, Kawi b-pipe manifold too small, a ported 701 yami b-pipe with adapter and different chamber will work if there are no clearance issues
 
Boyesen/Full Spectrum have a new gp800 intake manifold that went on display at Havasu. I'll try and post pics later.

thats awesome,Ive always thougt the 66e was a great platform for making killer power with the nicer cylinders and PV this could be the motor of the future if bedplates,exh mani and intake mani where out there for the sj and b1. you could make some serious power without the serious $ Ive also heard a lightweight crank is in the works for this motor,If the motor weighed the same there would be a even larger advantage to it

Little more progress, the headpipe actually bolts to the manifold now. Brandon's manifold is not really designed for this headpipe so some material had to be added to get all the bolts to grab. I think Im going to try a 1/2" spacer between the manifold and the cylinder, that way all the stock linkage can be used for the powervalves and it'll pull it off the oem tank some, its just barely touching now. Its going to get tested in the octane hull so just like the sxr theres plenty of room. Also need to make some brackets to hang the chamber, I'll run it through a oem sj waterbox first.

I need a stock servo motor and cables for the pv's if anybody has one.
