Keihin carbs.

IF the standard idle jet for your year of bike is #40, I see no reason to get a #38 jet.
It will just cause a high idle and other problems.
I would not do that. I would do a mixture screw adjustment FIRST.

#40mm WAS the stock idle jet.

Take Lucky's advice.

ya your right but already ordered,38 bucks worth of #38 jets

Just sell the unneeded jets on Ebay or Craigslist.

Someone with a smaller engine with Keihin carbs can use them.

Ot just return them for the ones you do need.

You may need those #42's trust me.
