Carb pilot Jet question

Carb question!! I want to replace the jets on my carb and I am a little confused my pilot jet reads 41 but if I look in the book it tells me I should have a 40 as a pilot jet?? So the question is do I go with the 41 which is what’s in now or the 40 like the book reads?? Thanks for the help

 

If your bike was running well before the carb work and you didn't change intake or exhaust setup stick with what you got.

 

If your running good; don't change anything.

The way you Idle and get out-of-the-hole will dictate what you should do next.
If your Bike Idles and you have not trouble getting-away at a red light; you're good to go.

Let you Spark Plugs coloration help decide what do do. ... too.
If the Plugs are a nice-looking Tan to Brown, ... you're where you are supposes to be.

If your LEAN and need to Enrich the Mixture; Up the value of the Jet.

 

Thanks for the help!!!
