Where do you guys connect your vacuum hoes for the downshifter on the R1 4XV engine? I can't find a place to that fits the supplied nipple. Pics would be appreciated.

I asked Graham from Flatshifter the same question a while back - He told me there is sufficient vacuum behind the throttle butterfly to operate the flatshifter module.

Drill hole to fit.

Thanks man!

Do you know what thread it is?

Cheers, Fredrik.
