Dong Fang DF250RTC Carburetor Re-Jetting
I have a 250rtc that I have been riding for about a month. They are geared very low, and upon the recommendation of other riders, I ordered a 35-tooth rear sprocket to get it about where it should be. I should have it installed in a couple of weeks. Next I want to re-jet the carburetor. It is a Walbro PZ26. Does anyone know what the best size jets would be to use? I thought I had seen somewhere that a 110 main jet would be right, but I can't seem to find it again.
Re: Dong Fang DF250RTC Carburetor Re-Jetting
Open up your carb and see what size your main jet is currently and measure the diamater of the thead so you can figure out which jet you will need. Start with an increase of 0.05mm (e.g. a 100 to 105), do a plug chop test and see how that goes.

Sounds like a good start. Thanks.
