Siebenrock Big Bore Kit 1070ccm fuel consumption

Hello

Does anyone has experience with Siebenrock Big Bore Kit 1070ccm fuel consumption?

What should I expect not changing any think else in the engine (Im even thinking of keeping the current R100GS camshaft)?

Thanks in advance

It depends on how you use it!

My full 1070 kitted bike gets between 40 and 50 imperial MPG, dells twin plugged etc erc. It goes well.

Built 2 bikes with the 1070..40mm Bings on both even though I have a set of Mukunis and Dellortos on the shelf..too many changes in altitude around here.

MPG all depends on the right hand...crank it hard and you get mid 30s...keep it smooth and around 64 mph and you can get low 40s.
