If your in the cold weather (which I'm guessing you are by your name), bump the slow jet size in your carb from the stock 38 to a 42.


*Edit*

Forget the name remark, thought it read "PolarMike"at first....Lol

yup, what he ^ said. $5 pilot jet from Honda #42. Very easy install.

Instead of sitting and feathering the throttlr for 5 minutes, I now only have to do it for a minute or less in oreder to keep idling.

Outstanding prices and super fast shipment. That's where I got all my jets. I recommend buying the stainless steel allen bolts that they sell for the carb. The stock screws are easy to strip out.

The pilot jet does not come with a new jet kit only the main jet does. You have to buy the pilot jet separately.
I purchased a DynoJet Kit and afterwards all I needed was a jet or two. I paid $50.00 for the kit and could have only spent less than $10.00 on all the jet I needed.
What's your set up. I'm sure there are tons of people on here with a similar set up that can give you an ideas what sized jets to buy. Save yourself some money and buy individual jets.

I have read that some people are switching to stainless bolts for the carb bowl. I believe that the screws are supposed to strip more easily so that you dont strip the threads on the carb.
