Mikuni BDST 38 Full restoration - Part 2

This is the 2nd part of the restoration of the Mikuni BDST 38mm carburetors from my Yamaha FZR 1000. Pretty much every other Mikuni BDST is the same and the procedure is almost identical.
In this video, I'm not only showing how to put together the carburetors, but also how to synchronize them and how to adjust the pilot screws!
This will result in amazing engine response and fuel economy too! These adjustment methods can be used in other carburetors as well.
Pilot screw settings:
FZR 1000 '87-'89
2 1/2 turns out
FZR 1000 '90 onward
3 turns out

very good video! I have a 2001 Yamaha FZ! it has Mikuni BSR37 carbs I believe. Also has Ivans jet kit. My bike sat 12 years because of surgeries. I have it running now. There is a little burbles at low rpms. Im going to clean them. I ordered new boots and carb gasket kit. Im very nervous don't want to screw things up. You have any tips or video on those carbs? Very well done video. GREAT photography. Up close, well lit!

[@ChrisSofos]

Thanks for your encouraging comment!
However, I've never come across your type of carbs, so I have no video or idea of their details. They all work the same, more or less.

[@muller_]

Thanks just what i needed. Near the end off my building process all thats needed now is to rebuild the carbs and then some small adjustments... hope the blaster will still be practical as im sticking with the fzr's front sprocket and the blaster's rear sprocket tooth count😂
Thanks for the informative video sir!❤

I have a yzf coming my way that’s having carb problems. I should have them sent to you.

I'll take that as a compliment! Thanks man! I might have to sent you the Gixxer's fairing as well.

I have yzf 750 r
Is it possible to have correct idle without airbox and filter and when you adjusting the pilot screw is it with or without air filter

[@ChrisSofos]

Very good question! Yes, that is correct. The idle will be correct without air filter/box. When the engine is idling, there's no difference whether the carburetors are naked or dressed with the air filter/box. There's no load on the engine, so no problem. This is why you can do the adjustments without the air filter/box. Just like I did.

[@ademcerkez4606]

Ok thanks for answer
