CR 250 R Jetting

[buster571]

Hey guys,
I need a little help i have a 06 and im having the worst problem with the jetting in this thing. Ive never own one as tempermental as this. I can run this thing all day long but as soon as i let it sit for a week or two she will not start on a used plug to save its life. Im at the stock setting except im in the 2nd clip setting on the needle. I pull the plug and she is wet as can be. Like i said before everything is stock. Im running Klotz 44.1 and still. Im thinking of going leaner but need some pro advice about which jets to use. Any help would be appreciative.

If it is stock jetting it is almost a sure thing the pilot jet is a size to big. Most bikes come jetted rich from the factory.. Also stock reeds can be less than stellar,, Had a set on an 01 Yamaha that no matter how the bike was jetted it still fouled plugs intermitently and had a lot of spooge.. Put in good after market reeds and it was much better.
