Hotter plug?

Update hotter plug and jetting(jaybird,nikki

sister just got a new 03 kx 125 and its her first 2 stroke, she broke it in today and doesn't know to open these things up. Stock bike with a BR9EIX, black spooge running everywhere(lol) and finally fouled the plug. I put a BR9ES that I run in my kdx 200 and got on it and I ran it hard and it ran great! She rode it for about 5-10 minutes after break in and you could touch the exhaust and cylinder head and wasn't very hot at all (just warm) Since she doesn't ride on the upper rpm's, should I drop down in the heat range and go with a BR8ES? By the way, first tank of gas was mixed 32-1 with Kawi 2 stoke oil and we drained the tank and used what we was using in the other bikes we ride with, golden spectro synthetic 4gallons to 1 pint. Thanks in advance

She is in heaven with the new bike :yeehaw: The plug I removed was totally black, maybe I just need to rejet, but it ran so good when I rode it, is a little booooggeee on the bottom and that is where she is riding it right now. Do you know the stock jetting on the 03 kawi 125? I haven't done jetting before, but it doesn't sound that hard, I have automobile mechanic background

Thanks for the help on the 03 kx 125, but before we had a chance to change anything, my sister just had to go race, she raced with the 250 beginners(men) and women's class. She won her first moto in the womens division, but she fouled a plug in practice and fouled another at the starting line in the second moto :ugg: we took it home and went down to a BR8ES and I moved the clip on the needle up one notch lowering the needle. Ran alot better(especially for me) but she still is not reving it up enough before shifting.Air screw was stock at 2 1/2 out, so I went to 3 out and it idled a little high so I went back to stock. Everytime I check the plug, it is wet and still getting a little blackish, but alot better. Should I go smaller with the pilot or main jet now? both are stock , 40 pilot(I think) and 420 main (for sure) Thanks for the help. Gary BTW went to Mobil 1 MX2T @ 32-1
