Episode 5: BMW K100 Cleaning & Prepping for Paint

In episode 5 I clean 30 years of road grime off of the engine, test the new ultrasonic parts cleaner, prep the tank and engine covers for paint, and front end parts arrive.

Unbelievable, dude. I just binged all 5 episodes back - to - front. I'm in Santa Cruz working on a K75, at this point I'm so humbled by your efforts I can barely bring myself to bother with mine since I know it's going to fall so short. Your design and production are amazing!

I want to buy a K100 for years, but the lack of space to store it and time to ride is stopping me to do it. Your videos are a motivation to finally gain some courage and get one either way.

Just finished my K100 build two weekends ago. Take your time and have fun with it. I sure learned a lot. Did the same as you on the engine cleaning. Kept everything together, and hung it from a engine hoist. Used engine degreaser, brushed and wiped down, then soda blasted the casing, then blew off with air compressor, used wax and grease remover (pre paint solvent), high temp engine primer (Duplicolor), high temp engine enamel (low gloss black Duplicolor).

Awesome job man! Tip for getting emblems off in the future. Apply heat with a heat gun and then use fishing string or floss to get behind and saw back an forth to cut through the softened adhesive. Once removed, soak it with goo gone and use more heat to remove the remaining adhesive. Works like a charm every time without damaging paint or emblems.

you should have put the cleaner in the bags and just have water in the ul-cleaner .save's on cleaning up just new bags

Nice job men, carefully and so detailed! I may recommend a heat gun to remove sticked emblems and protections, it helps a lot. Thanks for sharing your project.

Josh, a tip, if you have air compressor, get a small sand blasting gun and fill it with baking soda, gets all those tight areas super clean. Good video.

I love everthing u do. God Bless ur Soul bro. From nerway

Not only the outside, but also the inside of the engine needs some TLC after years of duty. I would have taken it apart and send it to a place where they can revise it. Not that much work from where your at, and it doesn’t have to cost that much. Also saves having to clean most parts in this video and makes the bike really stand the test of time. For the rest: Awesome project!! Love from the Netherlands.

newby design I've rebuilt/restored several bikes and tbh cleaning up old bolts is great until you start putting the bike back together, your immaculate valve cover etc will show them up for what they are, cleaned up old bolts. I found a local metal finishing company, took a bucket load of old fasteners and they bright zinc plated them without breaking the bank. Word of warning, if you take wheel spindles etc tell them to mask the shank or they will be oversize for the bearings. A gallon of brush on degreaser (I use 'no nonsense') goes a dam sight further than aerosol and can be applied using an atomiser ( get water soluble)

Great video

Carb cleaner works well in the ultrasonic cleaners. It's easier on rubber, plastic and aluminum as well.

Josh, to get glued parts off, heat with a heat gun to soften glue, comes off easier, we live and learn.

That sucks your Ultrasonic Cleaner broke on you brother I actually have the same exact one that I picked up for $60 and it works great bummer yours crapped out on you, and if you do this kind of work on a regular basis than yes you cannot live without that ultrasonic cleaner, you got to have one
