TOPIC:

found a stock airbox but im not sure what year of 900-1000 it fits i found this number stamped on the lid.khi dgm 313115 does this number mean anything?thanks!

Probably 900 (i think) Have the feeling that the 1000 didn't have the numbers. 900 has 3 "prongs" on the lid, 1000 has 2.

any idea what year?ill try and post picture.

I don't think it's from a '76 900. The number stamped on my airbox lid (the lid you remove to change the air filter) is:
KHI DGM 30386 S

Hmmm, I may have given you a bum steer. Have just gone and checked the number on mine (Z900) and it's the same as ltdrider's. Not sure of what this number means either, as it has no relevance to the actual part number that I can see.
