Not a lot of difference between the two bikes , if the power attained is similar with the 2023 H2 tune at this point .
But this is just a base tune for exhaust and derestrict on both bikes respectively . So , just freed up / removed the restricted fueling the Euro 4 in 2015 H2 and Euro 5+ in 2023 H2 .
Now the next stage is to try to make more power , and maintain reliablility , so both bike will need that billet plenum intercooler , and H2R camshafts . The 2015 has the turbosmart blow off valve fitted , the 2023 H2 will get one fitted with the update base tune shortly .
I will most likely try them out for awhile with that setup , the stock factory boost is 17psi (I think ) , so not low . Then the next step would be the supercharger gears , I got a set of stage 2 gears , maybe one will get that set to test .
Both H2 have clutch springs already and use Brembo masters on brake / clutch . The 2015 and 2023 have GP4-MS calipers ( not fitted on 2015 yet ) and the rear P2 Billet . I just ordered 1 set of Sicom rotors for one of the H2 , will decide later which one gets that set . Both will share the full Ohlins suspension , and I am going through both bikes with ti bolts and aluminum . The 2015 H2 is simpler electrics wise , the quick shifter is upshift gears only , the 2023 is a blipper shift . The dash is similar rev counter clock , but the 2023 has the tft panel over the lcd for 2015 .
Right now I am just putting the mods on them , and deciding as I go , I just like putting my bikes together , crossing the t 's and dotting the i's sort of deal , I sort of got a plan , it is to build them special .
