Question about 2005 Honda CRF 250 X
It sounds like the previous owner liked to tinker with the carb. I would pull the carb, CLEAN IT and check what size jets are in it. #115 is the stock main jet. #38 was the stock slow speed jet used that year. In the center of the slide, check where the clip is set on the needle. Position the clip mid- range of adjustment. If the bike bogs when you open the throttle, move the clip down one notch. Two notches may be needed but start with one. Be sure the owner has not lost the needle jet holder, part #16 on the parts diagram I am sending you to. Both the air and idle screws start at one & one half turns. Look at the tips of the adjusters. If they have a "ring" mark or depression mark where they were screwed in too tightly, then the screw(s) and jets should be replaced. These are adjusters and not really a screw. Seat them LIGHTLY then come out 1.5 turns.
Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part, the part is not in stock. www.babbittsonline.com/pages/parts/viewbybrandand/parts.aspx Go to the "CARBURETORS" tab to see the assembly. There is a slight chance the OHC may be one tooth out of proper position. We will check that after the carb has been put in order and tested.
I hope you will be able to rate this answer as "Very Helpful". Thanks
