Hello,
I'm a new user here, my name is Julius and I'm from Munich, Germany. Been reading a lot here and really appreciate this place.
I just got my first gen1 FZS 1000 and since it's a bit cold to right at the moment, I'm thinking about what tinkering I'll be doing.
The first thing is the Ivan MB Kit (along with the other usual mods) and a post on Facebook caught my attention.
Basically, he recommended simply rejetting instead of the Ivan Kit and also claimed:
"Drilling slide lift holes and clipping spring gives fast throttle response but usually at the expense of driveability."
So, I was wondering if there was anybody who has made this experience, and maybe felt that relaxed cruising was not possible anymore or even went back from the Ivan Kit?
For those interested, these is his entire post:

Quote:The FZS1000 carburation can be adjusted to run well in a bike with standard airbox/filter and standard exhaust or slipon (I’m using Akrapovic) without resorting to jet kits. This bike is set to run lean low down and rich up top - found after I had a fuelling check done by a respected dyno operator.
To fix the lean issue I fitted one size larger pilot jets (#17.5) set Pilot screws to 3.1/4 turns out. It’s not ideal but the stock #15 pilot jets can be used with Pilot screws set to 4.3/4 turns out.
Set float height to the standard 13mm which make fuel level the standard 3 to 4mm
Standard needles in standard position 3rd groove from top with the std 3mm nylon needle spacers are fine. Fuelling air/fuel ratio is flat so needle tapers are about right.
I’ve heard that some bikes have 2.5mm spacers? so these may need raising 0.5mm.
Fit 2 size smaller main jets to fix rich top end Main Jets - 127.5 on the outsides cyls 1 and 4, 125 on inside cyls 2 and 3.
That’s it.
