What did you do to your Yamaha today?

Hi there. I am new here.

 

Hi welcome which bike do you have?

 

the parts are already sitting on your bench now you need to get the door open

 

Welcome aboard! Don't worry about them, they're all nuts. I'm sane and will be looking after you Cheers!
PS: Wouldn't happen to have a right side muffler for an '84 XJ750RL would ya?

 

60 MPH wind gusts kept me from doing a thing with her.
At least Spring is here, finally.

 

Checked valve clearances and snapped a valve cover bolt off tightening it back up. Tomorrow will be fun. Anybody have any advice?

 

Don't wring off the stub with pliers. If it won't come out easy, don't force it. I usually just TIG weld a ball on the top and use that. If you can't do that or there is not enough screw exposed you will have to pull the head. You can try a left-hand drill bit but I would let a machine shop do it.

 

Don't do that?


How far down is the break?
Which bolt position?

Can you sneak the valve cover back off to get at the stub?

 

I went for a short 30min ride in the sun.
and now I know that the speedometer is not working right. Top gear at 4000 rpm said I was going 40mph.

repeat the mantra .... it's a 37 year old bike, what did you expect

 

This weather is Bi Polar ...it just will not give up, this high winds make it colder than it is . To the xj family PLEASE be careful after our extended long winter , already heard on radio a motorcyclist was killed hit by a car not seeing ridder be aware of chuck holes and loose sand and gravel and idiot drivers .( know you already do this but good to remind you lol) I care for all of us !!! Cheers

 

It was broken inside the cylinder head. I'm sure everyone thinks this, but it had to have been the bolt. I know I didn't over torque it. Drilled and extracted it today and it came out like butter. First time ever using an extractor. I'm pretty sure the bleeder screw that was broken off when I bought it won't be as pleasant an experience.

I also changed the oil and filter today.

 

I believe you. If the bolt wasn't the problem you would have either stripped the threads out or cracked the head. Shuldered bolts can tend to have a stress riser at the thread root next to the shoulder.

 

I like to put a notch in my belt when I successfully remove a seized or broken off fastener from alum.

 

Speaking of alum (the spice).
A service to those who don't know.

If I have to resort to dissolving the screw I will just drill it out and put in a Time-Sert.

You should check out the sway bar adapter torture test I did on my genesis coupe subframe adapter thread inserts. CNC 6061 and I install 20mm SS Time-Serts for the sway bar to bolt to. If you ever were concerned about strength of a SS time-sert in aluminum;

 

Dissolution is a good option for people who aren't experienced with precision drilling, or for fasteners that would require more disassembly to access with a drill.
No commentary about you, just seemed like a good opportunity to remind people about it.

 

I got my replacement lens for the Turbo. I fixed the last bit of damage from an earthquake in November caused a ton of crap to land on it in the garage.

 

Buttoned a few covers back up and slapped the head on the 550 motor so I could degrease the crank case bits. Shop crane tipped on me rolling out to the driveway and dropped it on the driveway. Luckily it was low but still managed to smack a corner of the oil pan and broke off a few oil filter cover fins. Nice solid thud. No case cracks that I can see. Might need a new pan. Hope not because I just glued that one on with a new gasket.

 

Recently as in last week had my xj700x seat recovered and in doing so I had a gel pad put in.
Got it back and went for 100 +- ride and was pleased with the result. I will upload photos later today or tomorrow.
Will also be taking the passenger seat in today to have the same operation done lol. not ad 300 bucks for both.

 

Put in a new starter relay.Fire in the hole,she runs again,ready to ride.
