So the issue you have here is you’re trying to get a worn out engine to run better/faster than standard in that case I would fully agree with Marcel valve tuning is the heartbeat of a 125cc engine it is the most crucial part of keeping your engine at its best therefore you should be doing your mods and gearing when you have your engine 100% otherwise no matter what you do you will never know how fast it should be or how much difference your mods have made
