Quick update,
thanks for all the replies, I am having fun restoring the bike to its former glory.
Gutted the oem air filter using the bracket to install the Nufoam.
Idle screw is aftermarket, it’s further out for easier adjustment. At 1.25 turns out
Yes the slide does function all the way up and down. I just took a quick picture.
Emulsion are clear
Tev diaphragm is working. Idle is normal. Also have replacement as needed.
Thank you for the detail description of the jets sizes. Knowing my choices as either oem replacement or diy. I accept and choose to DIY by drilling 1/16” or 0.0625”. The bike now runs better. If stock #145 is 1.45mm in theory this would be a #158.75 main jet.
Problem solved
Original topic:
No acceleration passed 4,000 rpm
Bike would sputter +/- 200 rpm, could not increase speed pass 55mph
Solution
Drilled main jet to 1/16”
Bike feels like its running normal.
Currently the air temperature are 50 Fahrenheit and air is super dense.
Not running stock air filter.
