Why must you post with these incessant Q's? I know everyone is new but come on. No two scooters are the same, even with the same tuning parts fitted. Hence why the rollers are often not the same and the same for jetting also. Have a look at the tuning guides on the homepage but just one of the reasons Ishigham said how long is a piece of string is rider weight. Some riders will be 8st and others will be 15. Doesn't sount like much but 44kgs adds up on a 100kg scooter
