If your running a stock bore/cylinder for an lt80, pre-mixing the gas 32:1, lightened up the rear clutches to 180grams and removed 2 rollers from the front clutch and milled the head .030" and with everything else stock, what Jet size should you try in the carb? Will the stock jet be sufficient? I can't remember but I believe its a .90 or .95???-I will have to check the book. Hoping to get an opinion here. Thanks!! That would be the main jet size too right? as messing with the pilot jet size is or is not recommended?

 

The stock jetting should be fine.

 

You should be fine with the stock jetting as long as you're using OEM air cleaner set up and OEM (factory) exhaust.

 

Even with a aftermarket exhaust, the stock jetting works good as they are jetted a lil fat from the factory.
