Hello all! Sorry to be long winded. I picked up an ‘86 champion with what I thought was an ‘86 150 XR2 on it. Well, it’s stickered a 150, serial says 175, and has (from what I’ve been told) carbs and horizontal reeds from a 200 (WH-22). Someone had modified the original choke plate to fit those carbs and ran it without the plastic cover. I would like to get it running right and put together right. Can I just track down an air box and cowl from a 200 and everything fit? Or is there more involved? Looks like a may need a different rigging bracket also? Any advice?
