97 octane fuel & a 15 tooth sprocket
Been disappointed with the performance of your z125?
Three tank fulls of 97octane fuel and a 15 tooth front sprocket (available at long last) and I am the happiest guy in the village!
It's great, hits the redline in 5th on the flat no problem, feels lively, cruises in 6th up hills or in to a headwind. It's bloody marvellous, it's now the bike that I thought I was buying.
