Finally after the US and long winter I managed to disassemble the whole bike for more upgrades. As we need to change a lot and some modifications to the engine itself, it made more sense to remove it from the frame. Overall, not so hard to take a part, just take your time and try not to lose focus of how things were put together. It took like 2h to get the airbox off and around 1 hour to remove the engine from there. Also did not bother to do it as fast as I can, therefore if you are in hurry, it can be done faster. Overall, I really liked the quality of things and there are only small things that could have been done better, like the air duct intake cut or some of the porting on the engine. The overall engineering seems good and I really like how the cylinder and intake port is designed. There are not many restrictions that could massively improve the performance as its built on purpose to have 15hp as regulations needs. Therefore don't think there are some easy ways to just unlock some HP on this stock engine. However if you know a lot of porting and other mods, this little thing has great potential, just its all of how much you want to invest in it and if the parts are available or needs to be custom made.
With airbox I decided to shorten the intake duct and add metal velocity stack that should direct more air into the FI unit. The similar shorter stack is used on the Gray Area modified airbox as well and it should allow more air on higher RPMs. I did not went with the open airbox mod as it seems to be overkill to give such an amount of air to the Injector. Even with my setup, I need to generate new fuel map that I hope can be used with stock injector. The one option was also to use 200ccm throttle body, however discovered that there are many bigger differences that would need more custom parts - but if no other options, I will try it at some point, but it will be hard to get it right I assume. I also managed to do the proper heat shielding for the whole airbox and hopefully it helps to keep the intake temp lower.
I also will update the clutch springs and add the Factory Pro ceramic shift kit. Then if we get the engine to perform, will also add the QuickShifter as the 6 speed gearbox asks a lot of gear changes.
Other then that, we also need to route the ECU wires to sensors and make the custom map for this setup.
