Hello guys,
I'm gonna try to keep it short and easy to read since I am not a native speaker. Also, please do not mind if I struggle to use the proper "names of things" because I am really not used to talk "mechanic" in another language.
Bike has now 44 000 Kilometers , or 27 000 miles if you wish, on the dash. Decided it was due to check the valve clearance, even if at least 8 mecanics (both independents and Yamaha officials) told me to "not bother".
I don't like hearing that, I don't like "not knowing" so I found someone near me who is knowledgeable (he is, but I'm starting to doubt he knew enough about this bike in particular) and we did the valve clearance check. Well, he mainly did, I was just there to assist and do the little things.
Values were fine, a bit close to the limit on some cylinders, but still inside the specs.
We reassemble everything, struggling like MAD to put back the accelerator cables (really, spent like 2 hours on this, was a nightmare).
She did not start. She was doing the symptoms you will see below in my videos. We thought it was the battery, which was old and already crapped on me a couple times. But even with a brand new lithium battery from my friend, she didn't fire up.
After a while, my mate went at the "front" of the engine, around the plugs and kinda "moved things around", verified nothing was kinked or spark plugs not seated or whatever. And it worked after a couple more tries insisting.
It purred fine, like, perfectly clean, nothing weird. Rode for an hour back home, even stopping for a few minutes at some point and starting it again without ANY problem.
Then she stayed for a week in the garage, and then when I tried starting it again, she did what you'll see and hear in the videos below. The same symptoms.
You can hear the "bonk" she does when the dash goes black. You can also hear it "stuttering", like she was just about to start doing the little "brop brop" from the exhaust. Also when I insist for a while, at some point she does a very loud BANG from the exhaust.
My friend told me to change battery, which I did, and also told me "turn the key on and off a few times" to initiate the fuel pump. That's why you see me doing it in the videos.
In the videos the battery is brand new and seem to give more than enough juice.
Do anyone here have ANY idea what could be wrong ? I'm at a loss here. My friend also told me that if the battery swap didn't work, I should bring it to Yamaha to have them "put the engine back to "point zero" and re synchronize" told me he can't do it cause it requires an external petrol tank while having the tank removed and the Yamaha computer hooked to the bike". (real hard to translate, sorry, hope you understand what I mean)
Is this bogus or could he be right. I'm starting to doubt him seriously seeing where trusting him landed me...
