Well, all depends on what the point of the mission is. Go harder, curiosity, tinker time, or the girl at parts shop is worth ruining your happy life for. π
If itβs go harder, then swapping in the biggest motor you can get in can be cost/time effective.
Going up bore sizes, can lead to a crank balance, thereβs a limit to piston weight, then it has to be balanced or might end up pissing you off.
The bike is what it is, more power will never make a better rider.
Curiosity, well you can read about it and what is the likely effect.
Tinker time. Hell yes. You get to learn things.
Girlie at the counter, stop fantasising, most of us are too old now. πππππ
