Amazing build btw! Sounds beautiful I can’t wait for part 3

[@franciscohernandez4207]

I like your videos, but I remember that once you put a translation in Spanish, I don't know much English, but I like to see the modifications you make

[@nuffysbuilds3750]

Very exciting mate, well done!!! Cheers from Nuffys Builds Also got one of these bikes under construction 🇦🇺🏍👍🏻

[@sahilnimawat6409]

Bro amazing your modification

[@julianbascle8481]

What programmable ignition box do you use?

[@epp9122]

Great as always 🙏

[@JM23007]

Damn thats sick.

[@TheSteveniell]

That’s fkn awesome! I have an 81 XJ650 and would love to do all that. I wonder how much it would cost if you do that to mine. 🤩

[@gregsochor]

I like your approach with tapping in to the oil-filter housing, but you know that you could just have bought the oil-cooler-adapter from the 750 and up models and fitted that one? Also that would have been after the oil-filter, i.e. meaning filtered oil to the turbo.

[@DoctorMotorcycle]

Had no idea. Tapping the oil filter housing is something I do on almost all Japanese builds almost purely based on habit. It was one of those "I already have everything right here to bang it out" type of things.

@@DoctorMotorcycle Was meant as constructive criticism. :-) Quite a few manufacturers did this at the time.

[@abdellahdrari8962]

Super! Si tu as l'occasion de la passée sur un banc, je serais très curieux d'en voire les courbes.

[@upsidedowndog1256]

100HP is impressive. Yamaha only got about 75 out of their version. I am looking for gaskets for a 85 Kawasaki 750 turbo. Mainly the exhaust.

[@motorax.service.motociclete]

nice job. but why programable CDI and not the standard one? also what kind of turbo\s do you use on these carb bikes?

[@DoctorMotorcycle]

To pull timing with boost, this bike was a GT15

[@trxtech3010]

Looking great Dr Motorcycle. I was curius about a couple of things, are you worried about the Exhaust Flow of the 2 middle Cylinders by chance? I ask this because I have ported a lot of heads and as for air flow I feel like those 2 middle cylinders might have a lot of turbulance to fight against at Higher RPM's.As for te Plenum Volume on the draw through set up just me assuming but I would think equal length intake Tubes would be better then a Plenum on the Draw Through set up? I Could be wrong. I assume you just have limited Space that is why you did what you did.

[@elketefokalaboca]

Yes. I was looking at the first video thinking that. And also lots of turbulence on the intake "box". Some smoothing on the pipes would make the airflow so much better.

[@old_horse_customs]

Nyloc nut on the header coupling ?

[@maksgarage]

Коленвал на вкладышах?

[@KenzoAkihiro]

A great project! Is the fuel tank original? If not, what is it? I like it!

[@DoctorMotorcycle]

Thanks, it's a Benelli Mojave. Took a ton of work to get fitted, wouldn't recommed lol

[@KenzoAkihiro]

@@DoctorMotorcycle It has given you good headaches! Thank you very much!

[@patrickroberts7847]

Back in the day your videos were longer. Wish that was the case now.

[@kiandawsonamador3041]

What’s the quote looking like for a 2012 Yamaha v star 250?

[@kiandawsonamador3041]

It’s a carbureted bike with 26mm Mikuni carbs

[@DoctorMotorcycle]

@@kiandawsonamador3041 Draw-through turbo setups don't work all that great on small displacement bikes, the vacuum signal is weak which makes it super cold blooded. When the power is so low to begin with, even if we increase it 50%, we're at about 30ish crank hp, still less than a ninja 250.
