    Took the Maxim out for the first ride of the year. Primed the bowls and tried the starter. Cranked and cranked. Acted like it wanted to catch a few times. Figured I flooded it. Pulled the plugs (they were black/sooty and smelled slightly of fuel) cleaned them off and reinstalled. Bike started within 15 seconds. Ran a little rough for the first 30 seconds and then smoothed out. Took it out for a good hour and ran like a top the whole time. My bike just does not like to sit for any extended time whatsoever. I have a feeling its running a little on the rich side. I just need to convince someone to do a little carb clinic in my neck of the woods lol. It's good to be riding again!

    Ordered the parts I need to replace steering bearings and rebuild the forks. I'm betting XJ4Ever gets the parts to me before I can get my garage door open (thaw + freezing rain = door frozen shut).

    Can't even bring home the new-to-me fjr1300 I picked up last weekend.

    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 :)

    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. :)

    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. :eek: Might need a new pan. Hope not because I just glued that one on with a new gasket.
