Hi Guys, Can you advise how to get a few new jets for the CRF150F? I am having trouble with it idling and running until it's super hot and was told to get a stock main and pilot jet, but cannot figure out how to order them (I'm working too many hours to run to the nearest shop, which is pretty far away). I remember having a box of misc ones at the shop I worked at in college, but since this is my first carb'd bike I really dont know how to go about setting them up. Thanks!
99113-GHB-1050 is for a 105 main. (stock might be a 90 or 95) Changing the first 3 numbers (like 115 or 107) should net you other larger or smaller main sizes available 99103-kpt-0400 is for the pilot (#40). So changing last 4 numbers to 0420 will get you a 42 sized pilot.
They're all cold blooded, it'll definitely run better with a bigger pilot, I think you want a 45 and remember you'll have to adjust the fuel mixture screw once you do. I'd recommend sticking with actual Keihin jets as a lot of the aftermarket ones are crap. CRF's only is one place to check out, but there are many others http://www.crfsonly.com/catalog/product_info.php/products_id/3201
