TURBO GUYS, READ THIS PLEASE - You'll notice I used an external wastegate but you can't hear it. This was because during filming, I had a pretty gnarly exhaust leak where the header bolts to the head. It was only making 4-5PSI consistently during the desert scenes, the EWG cracks at 8psi. I somehow managed to pinch not one, but TWO of the copper gaskets that go between the head and the manifold. You can hear the exhaust leak in the scenes where I rev the bike. VALVE FLOAT - When I sprayed the nitrous, the valves immediately started to float. I tried one more time and the same thing happened, I even tried spraying much lower in the rev range but still got valve float once boost hit. I'm going to need to put in some stronger springs before spraying again. It's a 20 shot BTW. A proper acceleration video comparing nitrous vs. just boost will be out later this year, after I take care of the next project (a '99 Kawasaki KX125). So stoked to finally do a dirtbike on this channel! It's not going to be a full teardown to frame build but it's going to get some goodies and get some life pumped back into it! -Jimmy

This sort of content is far superior to the "reality tv" style shows on cable/satellite tv. No drama or filler BS, no waffle, just the workmanship/engineering I want to see. Excellent.

Honestly this is probably the best, the most in depth and the most professional bike build I've ever seen in UKposts. Respect

In a world full of utter horse manure Dr Motorcycle gives me something to look forward to. Thank you and God bless.

You have literally taken the image of my bike out of head and put it into reality, You sir are a legend 👏 incredible bike.

Man what a ride 🤘🏻 I have seen some very impressive bike builds on UKposts but this beats the majority of them hands down. Awesome job thanks 🙏🏻

Finally, a build video where you actually get to see the bike in action...looks like a fun ride!

And so wonderful ! I'd love to own one for all the long rides in Summer. Thanks everyone. You are a real artist to my humble opinion.

These old bikes are so awesome and they’re everywhere. I love builds like this

I sincerely hope you realize how a good mecanic you are and are also proud of your accomplissements. Quite a great work. Thanks you for sharing. I spent a good time.

This is an INSANE build! I think I need a turbo setup like this on our next KZ build!

My Dad had a 78 kz1000 back in 81. I was 14 and rode it a good bit. It was a beast. He and I raced a lot. I had a cr250r. It was fun until 70 mph and then he would walk by me and wave. Lol. Love your craftsmanship brother.

A powerful device turned out! Dragging without tension!🔥👍💪

Absolutely amazing build brother. I always look forward to your new content.

I don't know why I recently discovered this channel, what an amazing craftsmanship, what a beautiful machine and oooh the sound, I'm in love.

Great build - not just the build but the filming of it and absence of unnecessary commentary (thank you!). Particularly love the introduction of that laid back hip hop jazz groove subtly in the background from 34:15 whilst you are ringing the bike's neck off road! :-))))))

Even with the exhaust leak - it sounds and looks amazing. It reminds me of the early '70s 250 Green Streak my dad used to zip around on when I was a kid. Fantastic build, bro.

Great and appreciated video! I chuckled at the brake caliper spreader on the tank. I have the same one so i instantly noticed it. Keep up the great content!

Your builds are just pure... Beautiful.

I love how you find these very cool Japanese bikes for cheap and turn them into works of art.

Man, that thing sounds good! You really got that turbo stuff figured out!

What great build Absolutely love it. Can’t wait to see what’s next

Gorgeous. I’m buying my first bike this week. A 2015 CRF250L. It has some mileage but I’m excited as hell to finally get on two wheels and learn all I can about motorcycles. Thanks so much for these videos. So soothing and I feel like I’m learning at least a little bit of something even without any explanations (visual learner here big time).

I had one of those motorcycles in the 1980's and I rebuilt it and and drove it everywhere. It brings back memories.

WOW! Truly amazing work, bro. Such a sick looking bike 🙌🙌🙌

One of the most fascinating videos I've ever seen on youtube. Incredible. Thank you!

I was in love with this bike when it came out. You made it even better!

Another great build Doc the detail you show us is really good.

I come back every few months to watch this. I brought a Kz550 and made it into a pretty sick cafe racer, because of this video. !

INCREDIBLE WORK, FOR REAL ONE OF THE BEST VIDEOS IVE SEEN

You totally blew my mind , you are so talented, extremely beautiful bike, have fun you deserve it

Love it bro ,it was sick even with the little adjustment needed,nice build ,nitrous and turbo on a scrambler lol ,can’t do nothing but love it

This, by far, is the coolest build on youtube.

As a tool truck snob, i can appreciate the use of harbor freight tools used well.

Brilliant video production ,so good to see the small stuff clearly dealt too.thankyou ..dope bro dope

Bloody grouse ol mate. You've got it covered in your vids. Thanks for sharing. 👌👆

Awesome Job! Thank you for sharing. I've got a KZ440 that needs some tlc and this look might work for it. God Bless

Love this build series. 👍🏼

Some crazy nice builds here, keep up the good work.

This was an incredible video Dr. Loved this build, my father builds rat bikes and I've seen many, many builds but this has to be one of my favorite rides that I have ever seen. Much love and respect from South Africa. Keep riding for a reason!

I don't know what's more insane, the bike or the guy riding it. That's awesome man, well done

Jeebus that thing looks like a metric crap-ton of fun. Well done sir. 🤘

Well done and looks to be allot of fun! ✌️

The amount of contradictions in this video is mind bending. Huge respect!

Wow, the revived motorcycle is wonderful ♪

What a great build , this is the first video I watched of yours definitely going to check more out.

Epic build

Your best build to date dude 😁😁🤘🤘

This is awesome stuff. Wish I could do this!

Bellissimo video, un vero Dottore delle motociclette .. 🔝Superlativo👍

Jest piękny, szanuje za włożony ogrom pracy. Efekt końcowy powala na kolana. Jeśli kiedykolwiek będziesz w Polsce to zapraszam na browara

Sounded excellent too.

Well worth the wait. But now I want more!!!!

Great job. Congrats

Es el segundo mejor trabajo que vi en mi vida, te felicito!!!

mad respect to the video.

Crazy beautiful!

Dude! Dude, Dude. Amazing. you made a KZ look badass & that’s no easy task I’ve had an ‘82 KZ1000 LTD parked for over 15 years that I wanna do something with very soon. you showed me so many things that will save countless hours of head scratching. thank you for sharing this entire creation. I do not plan to install any Power-Adders (for now) but considering a new’ish front end, if I can’t use stock forks to get the look & feel I’m after…I plan to be a little more street than scrambler. thank you again! I subbed immediately. unreal job, Sir.

Thanks for sharing 👍
