hi
i have not been able to test mine much since unblocking the slow as i found the pistons were scored then when i took it apart i found cracks on the exhaust ports so it is still in bits,but the brief run i did on it after i unblocked the jets seemed to fix my problem.sorry i am not much help,i have only had the the bike a bit over a week and only rode it a couple km to get it home and found all these problems .
