Hi Blaster Community, The blaster I bought used has a broken sight glass. I recently did an oil change and put exactly 546mL of oil in the bike. I don't ride much, maybe 5 times a year (up the block a few times). But I'm a hard rider, and I'm full throttle through every gear. Please let me know if I'm putting in the correct amount of oil for my riding style. Or would 650mL be a better. Please let me know. Thank you.
