Was Vehicle Towed: - Description of the Complaints: I have had issues with my yamaha fz6. the manual advises to use 87 octane fuel. i have been using 87 until the bike started to idle at very very low intervals. causing loss of power when driving, or stopped. normal idle is 1320 rpm. idle will drop between 600-800 rpm when stopped causing the bike to die (every time) or while driving the bike will idle fine then the rpm's will drop way down , then back up then down then way back up. i took the bike to the repair shop and they said they would adjust the bikes idle. this fixed the problem for a month and then i began having the same problem as before. idle dropping after filling with 87 octane. i decided to try other fueling stations 87 octane. still no change. i decided to try 89 octane. with 89 octane, small improvement, with the same issues. i then decided because of this problem causing me to have 4 close accident encounters to go ahead and try 92 (premium grade octane). this seemed to fix the problem of the idle dropping way down, however, the idle stays higher now than the normal 1320 rpm. now around the 1400 rpm range. the bike still has a issue with power cutting in and out with no idle change. i'm reporting this problem because i have had 4 almost critical encounters with other vehicles because of the loss of idle/power while either being stopped or driving. i decided to post this problem up on www.sportbikes.net. i found that 5 other fz6 riders had the same problem and that they too had close encounters with other vehicles. just fyi i made the post on 07/29/05 and already on 07/30/05 there have been 5 others with the same bike, having the same issue. this is a great amount. some have tracked this problem down to the tps - throttle position sensor. they reported after having this replaced this fixed the problem completely. sense i had this problem within the 6 months of having the bike, and due to others having this issue, a recall on this bike should be issued. *jb
