Regarding the throttle, this is my experience with my old 2016 H2.
Derestriction was purchased via Brockís, sent my ECU to USA to be flashed and returned derestricted & supplied with a PCV loaded with Brockís fuel map.
Positives: Complete derestriction, great service, fast international delivery, knowledgeable/helpful staff and Brock is also an approachable and very helpful guy.
Negatives: Iím in UK and the PCV map was initially too rich for our fuel, Brock helped me with this and it was much better after uploading a new map he mailed.
However, my throttle was always shocking, whilst itís supposed to improve the reality is that it didnít. Power, massive, controllability, finesse, NO!
I know itís helped some but personally I didnít want a mechanical ďfixĒ by dicking around with my throttle to slow down the action, no chance (on a £22k bike) am I cramming in a washer or fitting a new throttle tube.
I ended up taking it to BSD performance UK (my old bike still top of their list @250bhp)
BSD went back into the ECU and looked at the throttle map. Everything ďthrottle by wireĒ was at 100% & derestricted as per Brockís H2 ECU flash info. It was mega aggressive from low RPM hence still remained like an an on/off switch.
I left the bike with Mark @ BSD for a week and he dropped onto it as a project in between jobs. Eventually he mapped the throttle to be much more usable in the real world (like when picking it up out of bends and having a predictable delivery rather than ďall or nothingĒ doom switch!) Heís used this info to set up several more H2ís since.
Iím in no way being negative about Brock, as I say, great guy, great company and will absolutely purchase from them again.
However, the part done by Guhl (the actual ECU Flash) in my case, other than derestriction/massive power, didnít help the throttle & was perhaps made worse by the PCV fuel map being initially wrong for the UK.
I hated the delivery as it had zero finesse & was so depressed I went to test a Panigale V4 (that was a massive disappointment as per my other post!)
Throttle can be genuinely improved though, my advice is let Brock check your fuel map, and then find someone to get the throttle mapped via the ECU
