I wondered if anyone would notice Dennis. It's an '86. When I bought it, the tank had been replaced with an '85. I had the side covers and tail piece painted and decided to go with 85 decals for two reasons. The ones on the tank were good and I prefer the 85 cosmetics over the '86. Now I'm ready to fix the N/gear indicator light problem (always staying on N). Where do I start? Graham
