Keihin slow jets
I wasn’t sure if this had been discussed, If so sorry to be repeating-
My slow jets on my ‘73 CB500 are very plugged, I was told that aftermarket jets aren’t always true, I found a set from PJ Motorsports that fit but are too long and will hit the main jet hold down spring. I cut 4mm off and slotted the ends. 28mm is the stock jet length, 32mm is too long.
Here is a photobucket link to show pics.
