1982 wr/xc 250 carb.

My buddy has a 82 wr or xc. but his carb is cracked on the main body. will i need that exact carb or can i use a new more modern carb. I do not have the bike in front of me so i don’t have any # or size off of the bike. I'm just going off what he has told me. He is not looking to "show" restore the bike but get it going as a trail bike.

From the parts I have the round slide for the dual shock models, are longer than the more modern stuff. I suspect any 38 mm round slide body (off a husky to be safe) of the correct length would work if it isn't too worn. I would also check the diameter of the part which goes into the rubber near the reed cage if you switch to a more modern carb. I ended up using the rubber for the 40 mm carb and building up the neck of the carb with gas tank repair epoxey instead of stretching the 38 mm rubber.

It is hard to understand what you are looking at in the picture however what is shown is that an aluminum extention has been added to increase the length of the carb. this is a 38mm carb from a 2002 wr 360 on an 500 vingate left kick air cooled. I guess if one could get a longer rubber boot that would simplify matters.

HuskyT. Thanks and I do not mind.

Fran...K. with the mod to the newer carb does it affect the air flow through the carb? I looks as if you have been using the bike so how does it runwith it.

The carb I had was the 40 mm one with an even heavier slide than the 38mm ones. The idle stop screw finally had the threads give out and the bore the slide rides in was very worn. It starts better now and the idle can now be adjusted however I can't really comment as to how it compares to when the 40 mm (round slide) carb was fresh. Surely the newer flat slide ones must work better if that is all that comes on bikes for 20 years or so but the round slides have needle jets, I guess now if the hole the needle goes in wears you replace the whole body.

Ok thanks Fran. I will take a look at it first but now i have an idea as to what opts he has.

i have a spare 38mm roundslide carb body from my wr 250 83 . will need a clean and jets . intrested? cheers
