BLUF: Work on your own bike.

This ^^^^

Honestly by the look of the pics it looks like you don't spend alot of time taking good care of the machine - with that said, this could be a learning lesson to work more on your own bike rather then put it in the hands of those that are angry punching a clock....

So, another update. Spoke to a new customer rep/product specialist and explained everything in detail to him- including some points from this thread. He was more patient and willing to help. He said he would see if Yamaha could get a tech to go and inspect the bike and that if they could, it could mean the bike could be at the shop for a month, to which I was fine. However, he will let me know by end of the week so fingers crossed. If they refuse to help, I will continue to ask but I will also confront the boss of the service center about what his people did. If he is a reasonable & logical person, he should see what happened clearly.

This is a Yamaha dealer/authorized service center and if the shop is trying to commit fraud, Yamaha should keep a tight check on them but let's see. Seized bolts happen very quickly as I experienced recently. Though the chain adjustment bolt was fine and I could easily turn it, within a week, it "froze" and wouldn't budge till I applied heat on it! Just a few days of rain in a week did that! Though I admit that maybe I did not replace the chain "in time", there was no indication of issues with it- none of the service centers that I went to this whole year pointed it out either-no noise, no excess slack, nothing. However, coming to maintenance and neglect, perhaps some of you expect a pristine looking, shiny bike that never gets ridden in the rain or on salty roads- sorry, but I like riding too much to sit out those days. Usually, Sunday to Wednesday, the bike looks like how you would expect- by end of the week (esp if it rains) it probably won't. I can wager at least a hundred people will attest to how religiously I clean and adjust my bike every sunday outside my building but whatever.

Let's see how it pans out- I will definitely follow it to the end considering how sneaky the shop has been so far. Worst case scenario, I do bring bike home and try JB Weld/Aluminum weld fixes. Thank you all for your inputs, your insights are invaluable and hopefully, I can pick on some of your minds in the future too if this does not work out as intended. The one lesson I did learn is that I have to do all these smaller repairs/replacements myself- save money and save some time too as no one is going to be more careful on my bike than myself.

Don't JB Weld it! I'm sure it can be aluminum welded.

I second that. DO NOT JB WELD. Take it to a well known aluminum welder and have it fixed right.

Hopefully you can get this all sorted out and not miss to much riding time. :(

As for all the mess in that area??? Lots of chain lubes and auto oilers will fling crap in that area of the counter sprocket. You could have it nice and clean, and one hour later it's a mess, especially after one ride in the rain.

This is one reason I changed over from Maxima Chain Wax to Bel-Ray Super Clean Chain Lube. Even with the cleaner chain lube, it still gets messing in that area, just not as bad.

If the chain somehow did hit this chain cover mounting bolt, I can't see the cheap plastic chain cover surviving like it did???

When this is all over and you've won. It might pay to consider an old shitter as a commuter during winter. All lot of UK riders do this, it'll save your good bike.

Actually, I think what you are pointing to is the part of the crankcase and is metal! I posted the pictures a few days back but I cleaned it up and this is what it looks like:



That's how far that part sticks out of the engine...it's like a weak point and just another bad design decision on part of Yamaha on a important part of the bike. (Think oil pan bolt placement and all that pain..)


As for JB Weld/welding, have to scout of aluminum welders but that would mean taking apart the engine? And that means having to do it at a shop since I dont have the space, tools or expertise for that...

I suffered in the subway for a week after the incident... Don't know how I did it for two years when I moved here first, but it's definitely gotten worse(fewer trains+ more people)... however, I finally managed to borrow a friend's bike that we had rebuilt together for her-a tiny CB250 nighthawk. Still a WIP but so much fun... Under 300lbs, just a tad tiny for my 6' frame...



I have someone prepping a 600+lbs Concours for me... Not sure how I will feel about that! So, at least I'm still riding... Sad it's not on the FZ but two wheels are two wheels and that brings me joy.

Having a second bike would be very difficult unless I get a garage of sorts... Though something like the CB, converted into a Deus custom type machine could be fun.

I wouldn't be so quick to dismiss JB weld. If its done properly its a perfectly good repair and will hold up just fine.

Having it welded will be very expensive and require a lot of disassembly of the engine.

^^^^ This. Plus, i think the piece that broke off is only a boss to hold the sprocket cover. Some of the aftermarket covers don't even use it, so in theory, you could plug the hole with jb weld, discarding the broken off part and use an aftermarket sprocket cover.

I missed that one, but it would still show some major marks if the chain hit it.

And a big +1 for J-B Weld. I have seen dirt bikes with radiator fill neck broken clean off, then J-B Welded back on and zero problems. I suspect a radiator fill neck will see a lot higher pressures that the case would ever see. Plus J-B Weld has been the go to fix for dirt bike case cracks, punctures and major holes for years. You will find lots of Adventure Riders carry J-B Weld (or similar) as part of their tool kits.

I've used JB Weld several times. I'm impressed with it's strength, but I wouldn't use it for something that must support a lot of force. This does not seem to be a part that is under much stress in normal use and is the perfect candidate for JB Weld. Just make sure the parts are perfectly clean before you apply it and that it's adequately supported while curing. I would not recommend using the bolt to hold it, since a little of the epoxy could end up bonding the bolt to it.
Also, when I've used it, it seems to take a lot longer to set up than the instructions indicate, so give it plenty of time before you remove what's holding it in place.

I never had have any luck with JB weld,

someone I know did however use JB weld to patch a hole in a tranmission that a rock went through, patched the leak easily with JB weld,

for some reason I never had any luck with it, even doing everything spot on to the directions.

I would think the shop that did that to your bike would have to fix it out of their own pocket, you paid them to do the work, and they haven't fixed it yet.

Another vote for JB Weld (or PC7, PC11). Epoxy repairs have always worked when I've needed them. The added benefit for the epoxy is that you won't have the heat from welding to distort the angle of the boss. Plus, welding cast aluminum requires a deft touch - definitely shop around if you go that route. If it were my bike, I'd give the epoxy a try before welding, but that's just me.
