Scooterotica

After weeks and months f'in about with the jetting on my GP150 with Sterling, I stumbled on a bit of luck. No jet would help the performance of my GP? Until I drilled out an old jet and fitted it. Not expecting to even get a kick, GP now flies! Top end not too good - 55ish but I have ordered a 4.00 rear tyre which I hope will improve 4th. Pulls very well in 4th and like a train in 1,2 &3. Anyone else had a bit of luck while messin around?
Cheers
