Best video I have seen to remove the air filter and replacing the plugs. Thank you!

[@bderkhanvlogs4715]

Thank you! Figured I’d make my own since none showed how to do it in every step

I have a gen 5 vfr800fi and was considering moving onto a st1050 but after watching this video I'll give it a miss. Excellent camera work with good tips though.

Nice video, straight to the point. No blah blah blah for 10 minutes before getting to the work. Thank you for putting this together.

[@bderkhanvlogs4715]

Thank you! That’s what I was going for. I was struggling to find a good video on how to take the tank off… decided to make one myself

[@martingecko2786]

Great video, articulation, details showed and fully explained. One of the best ST maintenance videos I've ever seen 👏

[@bderkhanvlogs4715]

Thank you! Figured I’d make a video since there’s practically none out there
