Bailey Posted March 8, 2013 Share Posted March 8, 2013 Hello everyone, My dad and myself recently got a 1987 xv1100 to fix up togehter and turn into a bobber, but it was mostly dissassembled and we seem to be missing a few pieces I need to to know if we legitamatly need or can do without. We seem to be missing a piece called the "sub tank assembly" and we arent really sure what purpose this serves in the function of the engine and if we do in fact need it for it to operate. This is the first motorcycle I have had to work that is carbureted, so most of it is new to me. Any information you guys could provide would be a great help! Thank You!

neversaydie Posted March 8, 2013 Share Posted March 8, 2013 Never heard of it. Could it be the emissions canister? or the fuel tap? Link to comment Share on other sites More sharing options...
dav a Posted March 8, 2013 Share Posted March 8, 2013 I used to have a 1992 model it had a small fuel tank on the left side under the seat behind the side panel I think this could be the sub tank assembly it was basicly a reserve tank Link to comment Share on other sites More sharing options...

It also appears we are missing the AIS and MCV, which appear to have been removed by the previous owner. What effect does the removal of the AIS have on the bike, and is it something we should try to replace? All we really have is the frame, wiring harness, engine, carbs and tank.

Mixture Control valve? All to do with reducing emissions I think, and reducing backfiring during thottle off Link to comment Share on other sites More sharing options...
