USA vs CANADIAN spec
on: November 24, 2020, 04:26:40 AM
It appears the canadian spec zh2 has 40mm throttle bodies while the american spec bike gets 36mm.
(Much like suzukis gsxrs back in the day)
I believe peak power is the same on both. Would that not mean canadian bikes are slightly MORE restricted?
Anyone else notice this?

Really ?   :002:   Didn't know that.

Not getting mixed up with the electronic throttle valves are you ? as i think they are 40mm.

See what you mean, although they are a little different. CA does not actually mention "throttle bodies".

CA:

Fuel system: Fuel injection: ø40 mm x 4

US:

Fuel system:  DFI® with 36mm Keihin throttle bodies

Yes, it is confusing. I see it being possible though. In canada our gsxr 1100's back in the 90's had 40mm carbs while in the states they came with 36's. All the magazines would praise the zx11 as being the quickest open class machine yet here in canada the gsxrs were dominating. Im guessing it was due to our bikes having an extra 10-15 hp due to the 40's.
I would love it if we had some real clarity on this issue.
