2t bad for my block , selection 2t

Hi-rev 500 ungu bad for my block . Hi rev 800 okay still hv smoke , petronas sx okay low smoke , xt (low budget) but heavy smike.

Choosing 2t is somewhat very important to 2 stroke motorcycle. I rather say it depends on the owner. Neither he wants to spend extra money nor not to buy an expensive and high grade 2 stroke oil. For me, it depends on the load demand of your bike and your riding style. if you are a high revver person, better to use a high-grade 2t oil that meets requirements JASO FC, FD and above.
