check for vacuum leaks near intake boots with a carb cleaner or starting fluid

maybe see what the plugs look like, I’m sure they probably look fine given you only have a big in a small portion of the rpm range.
Thanks mate, I will give that a go and hopefully get some progress. Appreciate the guidance.

Absolutely, if you need any photos I may be able to help, but mine has a pair system delete, DAI valve delete and the carb coolant line delete, so I’m running the bare minimum (when I bought the bike it was all annihilated and couldn’t be salvaged)
let me know what you find out.
