[QUOTE="SPORT, post: 570659, member: 6195"] Now evening. Ran bike temp up to 3 bars, held throttle @ 3,500 RPM. Engine RPM fluctuated about 200 RPM, but dipped to 2,900 for about 15sec. then jumped up to 3,900RPM before settling back at 3,500 with a variance of 200 RPM. Shut bike down and checked the TPS. Idle was 16, & full wide open was still 100. Even a slow roll on of the throttle did not reveal any inconsistancies. Although the 200 RPM variance seems a bit excessive, the drop of 1,000 RPM was quite surprising. Now the question is whether it is electrical, fuel or air related. Guess I need to spray the wires and hoses looking for arks or even a vacuum leak. Waiting on parts to complete my home made TBS tool, then I'll complete the 'unauthorized TBS adjustment'. Just found [URL="https://www.fjrforum.com/forum//index.php?showtopic=13800"]this thread[/URL] about making sure the spark plug wires are firmly in place. Guess I'll be checking this as well. [/QUOTE]
