Damn, looks like my main sled is a wife's sled. My 95 zr 580 efi has never had an efi related problem. Couple things of concern. ***Before you ride this year I would check the condition of the intake boots, very common for these to rot out.*** Mine rotted holes in the bottom and caused motor failure (allows extra air into motor). Also if your sled has around 4,000 miles there is a good chance your primary clutch will need work, at least it should be looked at. Make sure you have a good battery and clean tight connections, remember your sled will not run without the battery. Check all skid frame bearings. I had ro replace a jackshaft bearing around 4,500 miles, (no speedometer working is a clue that this bearing is junk). Happy trails.
