You are definitely inspiring me to finish my incomplete build I started years ago but set it aside after I got married and had kid's. Now my daughter wants to build the bike with me. Good stuff and you've probably gained a customer.

[@jupiterjohnson7191]

Bro you have no idea! How much you are helping me right now! Thank you!!!!!!

[@DriversSide]

Excited to see how this build turns out!

[@bikedogtor1663]

Great to see the inside of the engine. I didnt get to rebuild mine bc it was done already. Maybe I get another R100 project bike for videos with a seized engine, looks fun.

[@ChristianRB89]

This is a /5 bike/engine. An R75 was a warbike made by bmw in the 40's

Looks great 👍 next time lube your rod.bolts before torqueing or you'll get a false torque due to the thread friction

[@cozydram1]

I totally have enjoyed watching these video's ....I do have a Question seeing you reinserting the cylinder studs. was there a torque setting on those, so far I can't find any??? please and thank you

[@ou7shined972]

Having rebuilt my "83 R80 TIC last year, I'm loving watching this in depth series and re-living processes I know very well ... but I'm a bit concerned that in fitting the head gasket you siliconed over the oil way along the cylinder head bolts

[@oxwecustom]

Gorgeous!

[@sylwia1398]

To mouch silikon and gasket cylinder to the block!!!!! And missing silkon ruber !!!! pipe!!!!Bolix!!! Sheat job!!

[@CognitoMotoTV]

Not all the models use the rubber so it is not ured on this build.

[@gonzalosalinas2610]

It doesn't look like a motor. 🤣 My thoughts exactly.

[@AS4RONIN]

Just found your build series, fantastic. I’m have a question (or two).. Converting one of these BMW’s in the same way is something I’d like to take on, my question is once I find my diner bike, how many of these aftermarket parts, notably the rims with disk brakes, and front forks (as you ave used in your build), at actually available from third party parts providers “without” the need to modify the frame? In other words are a large majority of these after market part designed to retrofit onto the existing frames? The work itself, while tedious, does not concern me, I;m just not clear if I can replace items like the front fork with modern variants (like yours) with aftermarket’s without having to modify the original downer bike frame (welding, etc).. thanks in advance..

[@CognitoMotoTV]

We manufacture and sell these aftermarket parts, designed for bolt-on installation. This means that modifying the vehicle's frame is not necessary to use our parts.

[@AS4RONIN]

@@CognitoMotoTV thanks for the reply

[@liljedahldk]

Love the videos. But you need to turn off the Auto Focus and set it manually to the point that needs to be in focus.

[@benjamincai156]

I just get started on all the custom motor cycle journey, how can I get a BMW R80 manual? Much appreicated!

[@halmcclain3322]

No checking of either the crank/rod bearing clearance or the ring end gap?

[@kizito8301]

No gapping of the rings???

[@CognitoMotoTV]

We had to check it but they came to spec so no filing was required. Unfortunately, I didn't realize I missed that footage.

[@sbaraffo]

That silicone ruined the entire video
