Well that new dunlop 404 tire i had causing my bikes unstable hadnling wasn't underinflated.
I tried the the rec my yamaha 36 psi
/then 38psi/then 40psi & it didnt fix it.
,its pretty common with many biles that when front tire is at least 50% worn out or more to sart to get the wobbles. Not always bad enough to affect handling much if at all with both hands on bars but enough to get some wobbles with no hands on bars.
