Good luck on getting to 50. I hope you don't use your scooter as a primary means of transportation. Modified that much it won't last very long.
..i've been running my '08 WOT, all around the 50 mph and above mark, for over 25,000kms...
..51,000kms total...
..it's all about how you keep your scoot maintained...
..running as i do, every day, one MUST perform routine maintenance WAY more frequently...
..and, of course, every build of scoot is not the same..what works for mine may not work for another...
peace
