Hey all,
I've been a long time owner/collector of many vintage Honda's which I ride regularly and daily, however I've recently taken the step up and become a Goldwing owner! I picked myself up a 1985 GL1200 LTD in great shape. The other day I ran into a small issue on it and I'm hoping one of you LTD/SEi guru's may be able to help me out. My issue takes about 1 hour of riding to develop and once it develops it can be replicated fairly consistently. Here's what's happening:
In situation where I'm riding on a flat stretch of road and the engine is running in such a way where the bike is not accelerating nor decelerating and it held at a perfect speed (particularly at 60-70kph, yes I'm Canadian) the engine will cut out very similar to if it it running out of fuel. If you accelerate it pulls fine, no problem under deceleration, however it will develop once you start to roll from a stop unless you keep the RPM's above 1500-2000 range. If the engine speed isn't dramatically increased and I ride the clutch it will cut out and cause a stall. No fuel system lights come on, nor are there any lights displayed on the ECU when it's occurring. Fuel filter doesn't seem to have any abnormal obstruction, fuel pressure remains constant at around 30psi while the problem occurs, spark plug burn looks good, compression is good, fresh fuel, air filter is clean, tested nearly every sensor on it as per the supplement manual and everything seems within spec. The problem doesn't seem to exist above 90 KPH just around town and sometimes just a little bit of hesitation after changing gears and accelerating. To me it doesn't seem like a spark or ignition issue because there is no backfire from unburned fuel on a missed stroke, it just acts like there's not enough fuel getting to it. Does anyone have any ideas on what I might be missing or where to go from here? It starts up cold and runs great until about an hour into riding. Doesn't seem to be directly temperature related, happens at 4,5 or 6 bars on the coolant gauge, doesn't seem to matter. If it stalls it fires right back up, no loss of spark as would be expected with the common pulse generator issues and not at a consistent enough point of throttle to convince me it's a tps.
