Another good free one is to take off the exhaust header then grind and smooth the welds on the inside of the flange where it connects to the cyl head. Suzuki should have made the welds on the outside of the exhaust flange since it chokes airflow
I reused the stock spacer trimmed to "D" shape on top the clip so there is no side loading on the needle. I think this comes with the new procycle kit and is not included in the JD kit I brough.
Also, is there a way to replace the US spec OEM float boat with an overseas one that has the Overflow tube in it? I think this us design is ridiculous and the first time in my life after having 30 motorcycles, I had this stored over the summer, got this bike started again while running the float stuck open, flooded into the engine, filled the crankcase with gasoline, and pumped it into the air box so mixed gasoline and oil went all over the floor. All because it didn't have a float Bowl fuel overflow
That seems likely. Just don’t drill the slide or cut the spring. I’ve rejetted mine without doing that and it runs fine. I’ve got videos on my channel.
Not a single video on the net mentions removing the little switch & wires on the right hand side of the carb that is pressed in on full throttle, it's damn near impossible to remove. I think this is Australian only cos I don't find the item on partzilla
Best video I’ve seen on this process. I’m tackling it tomorrow, so thanks for posting this.
Thank you for making and sharing this. Thank you for the effort.!

What is the unused threaded hole for in the bottom of the float Bowl?
They seem to all have this and I can't find anything out about it

You omitted to change the pilot jet
I have read that these modifications cause accelerated wear on the carb internals . . ?

So, the dr650 carb is Mikuni BST40. Do you know what the Mikuni model is for the DR250s (1990-1994)?
thank you for your time.

May be so. That is your rev limiter switch I believe your’re reffering to. Have not seen those on U.S DR’s
