Hello I hope i am somewhat in the right section for this question. I purchased a 1981 KDX175 and bike over all is in good shape. I have got it running and it doesn't miss a beat. However it needs a carb holder(flange from carb to cylinder) and they aren't available anymore is there any that anyone knows of that will match up and I am also wondering if anyone knows what i can substitute (replace) thefloat, needle and seat in the makuni VM34SS carb that is on it any help would be great I would hate to see this bike go to the junk pile.
