You should run 93 or higher
You should use 93 Octane in your bike.
I was told to use a 32 to 1 mix by a bike mechanic
Regular gas should be fine
Flex-fuel (unleaded/E85)
he uses a suzuki RM 199
I use LRP type gasoline to my '96 suzuki dr 200se
For savage 650 or 400 you should use chain 525. It strong enough to make your bike run well.
Yes you can use 2 cycle oil to mix with the gas for a mini pocket bike.
Depends. The e-bike itself doesn't use gas. But it's possible that gas was used to generate the electricity that charged the battery that is powering the e-bike.
93 octane
well that depends if you have a two stroke or four. if yours is a four stroke, use straight gas. if its a two stroke use a gas+oil mix. you should know the mixing ratio. lots are 40:1 but it could also be 32:1 depending on the bike.
That's impossible to say seeing as you didn't tell us what motor or even what bike.
