I'm a professional software developer by day but this channel is about all of my hobbies. DIY, wrenching, dirt bikes/motorcycles, motovlogs, tools, reviews, reef tanks and so many other things.
Regarding rebuilding engines and fixing cars/bikes: I write code for a living, I'm not a mechanic. Reference my videos at your own risk. I highly recommend you watch my videos only as a supplement to following the appropriate steps in the service manual.
