ViragoTechForum.com XV700 AIS/MCV or what? (SOLVED)

#1:  AIS/MCV or what? (SOLVED) Author: hamgravy Post Posted: Thu Aug 26, 2010 7:37 am

This is probably a dumb question but I have not been able to find a clear answer with pictures anywhere, not in the forum or in the manual for this item on my 86 XV700.
The first time I removed my carbs I would have bet $100 it was a fuel filter. After ready several posts I believe that the only filter is a petcock screen and this is probably the AIS/MCV combined.
Any help please.

as dan said: it's the mixture control valve...the ais [air induction system] appeared in later years

you will remove the "T" and hoses. plug the big nipple on the front intake. and route a new hose from the little nipple (front intake) to the peck cock.....dan
