well if yuour going to mess with the jets you better be sure your comphy doing it becuz you will doing it all the time to try to get it right on with the temp fluctuation...you best bet is to find a happy median.
Get a Tempa-flow from Holtzman Engineering. It is an automatic temperture compensator and it will keep your jetting adjusted as the temps change. I installed one in my 94 ZR 580 a few years ago and it works great. It is especially great on the days when you have wide temperature changes from morning to afternoon and back down in the evening. It is probably about as easy as it gets to change jets on these sleds, but it is so much better when you don't have to.
