GPz 1100 fuel injection?
03 Jan 2016 15:22
Thinking about another bike, z1300 floats my boat, but I'm thinking GPz1100 would be more my 'cup of tea'. (English saying)
Most elderly GPz11 seem to be on carbs now - makes sense I know, but if I get one I really want it on fuel injection. These bikes are arm wrenching enough so this isn't a dyno chart competition, so not looking to tune it at all.
I like the B1, with it's brutal looking clocks, brings back memories as a teenager ... ZX unitrack is out -don't dig the styling sorry. B2 is out as I'm lucky/financialy irresponsible enough to own a genuine ELR.
Any owners here with a B1? would updating with later and improved B2 components work?

B1 has injectors in the head. You will need a J head and the B2 system.

so a B1 with it's iconic looks for me, but maybe a zx1100 head and later DFI engine management plumbed in?
Doh! just for once in my life I want to buy something nice and original off the key, no spannering involved...for now.
Does this give better / worse throttle response than a CV34 carb mod?
All my bikes run really nice on pods...with some tweaking...does DFI accept pods?

Just checking in Brendan... unfortunately, DFI is completely out of my wheelhouse. If it came with added-on carbs, I'd probably try to work with them first, before going back to a Kaw injection system, at least to know the motor and ignition are good.
