[QUOTE="RossKean, post: 1423466, member: 19880"] I very much doubt that a couple psi would have any bearing on the error. I would be surprised if a gauge was accurate within that interval in the first place. Fuel viscosity as a function of temperature or formulation would likely have more of an effect on delivery than a 5% difference in fuel pressure. The manual suggests a few things but I think I would check out the O2 sensor (and connections) first. I once had a rich running condition when I pinched the O2 wire in the timing cover after some maintenance stuff. Don't remember any error codes but it ran stinking rich! Is the bike running OK? Is fuel consumption excessive? Does it smell like it is running rich? Does the error come and go? If so, under what conditions? Try a dose of fuel system cleaner? I had the Error 32 on my '07 shortly after I bought it (used). In my case, it was related to a Power Commander which I ended out taking off the bike for other reasons. (I know that isn't your situation as you clearly stated there are no aftermarket devices on your engine.) [/QUOTE]
