A have another V4 Honda, an ST1100. Given that it has gear driven cams (plus a belt drive), I'm choosing to call it my VFR1100ST, but I digress... The bike was parked up for 8 years and was predictably clogged up in the tank, fuel pump and carbs, and I have spent many happy hours snorting carb cleaner, and fitting a new fuel pump. The ST1100 tank has a big flanged opening that you can get your arm into so I was able to scrub the inside clean. I've set the float levels carefully, verified the jets are OEM, checked the diaphragms are clean and the slides work well, then balanced the carbs. I now have a bike that starts from cold nicely with choke, and idles like a fine Honda should. It runs great at low revs (up to 4k) and small throttle openings, but when I open it up it gets the staggers, feeling flat and misfiring. It will rev right up to 8k with an effort but doesn't feel happy doing it. I have started looking at the electrical side of things, and the one anomaly is the power supply to the ignition control module. The manual states I should get normal battery voltage between this and the ground, but I only see 11.15V. The bike has got a brand new battery that gives 12.7V on its own. Is that lowish voltage at the ICM a cause for concern, and if so where would I go looking for the loss?
