I've owned an 87 250sx since I was 12. Grandparents bought it new for me and it's pretty much all original. I recently acquired an 86 250sx. It runs and drives. The 86 did not come with intake hose or carb hose to inbox. I noticed on my 87 there is an intake hole built into the frame but the 86 does not. Does it even use an intake hose or does it use the plastic piece like an 85 trx250. I've looked at all the airbox diagrams like at babbitts but 85 86 and 87 250sx all show the same parts.
