Sorry buy I tried the search and did not find any info so here it goes. I just installed my CDI into my 06 660 and now it seems to be running lean going off of smell of exhaust. The kit says no adjustments needed but I am thinking maybe I do. I also just bought the Rhino and changed the oil and filter as well as the air filter which was pretty dirty. Yamaha said they run lean to begin with so is the lean coming from the cdi or the fact that my Rhino can breath again ? Yamaha said to bring in my carb and they will rejet for free which is cool considering I did not buy my Rhino from them I only purchased the CDI from them. Any suggestions would be appreciated.
