Hello VFRD! I am new to riding and got a VFR800 8th generation from 2014 as second motorcycle. I bought it used with 5000 km 2 months ago and I have ridden it 6000 km with it in this time frame. The maintenance is soon due, at 12000 km. I was planning on cleaning it and doing some minor maintenance, with the agreement of my local official Honda dealer / garage. However, on Saturday morning as I was firing it up to buy some of the tools I would need for the maintenance, I forgot to remove the disk lock on the front wheel, which broke a small part of the front fender. I consider this a non event but who knows. After assessing the damage (none that matters, or should matter), I tried to drive away and a loud rattling noise made me reconsider it. While I do not care so much about cosmetics, I do not want to risk any damage on the engine. The bike starts without an issue and keeps a constant normal idle rpm. The noise starts as soon as I open the throttle, with or without a gear engaged, with or without the clutch being engaged. I have removed the fairing to try to hear more precisely where the noise comes from and hoping I would see something loose. Now that the fairings are removed, I think the noise comes from the right side of the bike, around the front right cylinder. Looking on Internet, I understand this might be the front Cam Chain Tensioner being worn. This seems very early at 11000 km. Could anyone point me towards a potential culprit and how to verify the hypothesis? Should I just go to the dealer and not touch anything? I might be wrong so if you got suggestions do not take all of my rookie analysis as solid. I will try to post a video with the issue at hand during the day.
Hi All, I've bought the Power Commander 5 and Auto Tune kit, and today have just installed only the PCV (ran out of time for the Auto Tune). I loaded a generic map just to see how it goes, but it's running way too rich. Smoke out the exhaust indicates that, and it wasn't happening all day yesterday before the install. I have noticed an issue with the throttle position sensor, which I tried to calibrate by powering on the bike (but not turning it over), setting the left side to what the current voltage read, then turning the throttle all the way up and setting the voltage to the right. It did help, but I noticed a weird flat spot at around 22%. Even thou I turn the throttle on evenly and slowly, it will go up to around 22%, then nothing for a while (I still continue to turn slowly) until about 90% open (I'm guessing based on how far my wrist has turned the throttle), and then all of a sudden it goes fast to around 100% fully open. Best to have a look at the footage I recorded, and bear in mind that my wrist is slowly turning the throttle and the voltage is jumping around a bit. Also, if you turn up the volume loud you could hear a weird 'buzz'-like sound at near 90% open, which it seems is the give way area to where it goes fast to 100%. Anyone have any thoughts on this I would love to hear them.
