g'day , i recently purchased a mc18 for the missus , currently she is in a sad state (the bike), i am looking to do a full tyga upgrade and am wondering if i put on the top end kit 300cc will i have to get the bottom end done ???? Also if there are other things to consider when doing a tyga job ???? i've been riding bikes now for 7 years but this is my first 2 stroke so the mechanic will be doin the engine work.....
