Ok i just got a good deal on a busa. It needs some work, but i didnt know it was to this extent. Ok im a newbie I have pretty good knowledge of what im doing, but i need some help
The cluster has some weird wiring issues. The tach idles at 3k, even though it is at normal rpms. the spedo is stuck on 110 whether the ignition is on or off. The engine temp is broken.
All this just seems like a cluster, but it misses and sputters at low rpms. once to mid-high it is fine. Sometimes it even backfired through the intake.
The bike is an 02. A couple owners before me put a 06 motor on it. Idk what the problem could be. I need help!
PLEASE!!!!!!!!
Taking into account everything you have provided and maybe trying to "see" through to what you maybe encountering; The Combination Meter (or gauge cluster to you) is made up of four "Stepping Motors" that operate the Speedometer, tachometer, fuel meter and the engine coolant temp meter. All meters will move to a full-scale immediately after the ignition switch is turned on to enable self-calibration. et al., from the service manual.
To reset - follow the full procedure below to hopefully gain a clear indicating meter.
If you have found that one or more 'Step Motor' is faulty (like the engine temp), you may be better served to replace the whole gauge cluster rather than to replenish the individual step motor itself - i.e., cost of individual v. total replacement.
Also, what I would do on the rest of the bike is remove all panels and give the bike a thorough pre-flight on all torque specs. As you go around all points, note where you find a lose bolt. You may just stumble on the lose fitting right away. If you need torque specs on specific areas, let me know.
