    Well, the old plugs (which aren't very old) did just fine for a ride up to Denver to see Alan Parsons. About 125 miles round trip. Plenty of close-in parking for motorcycles in half-spots left next to people that can't properly park a car.

    Had an intake valve that was a little wide (.16). Got it changed out (.11)

    Read the plugs and put 1/8 turn closed on the one that looked a little rich. Then did a good resync and tried to get really accurate with it.

    Oh my :D:D… she lept out of the neighborhood like a just branded gazelle...

    Got the fourth BPR7EIX and swapped out the plugs. Noticed that #2 is a bit leaner than the other three, which all look really good. I'll have to think about how to approach that. I don't have trimming for individual cylinders... just for 1/4 and 2/3. It could, I guess, be valve lash out of spec on that cylinder, or a partially clogged injector, I guess. I did have all the injectors cleaned and tested before I installed them, though. I have been thinking that I'd like to switch to some smaller injectors, to allow for better resolution on the fuel delivery. This might be a good opportunity for that.

    Wet set both sets of carbs earlier - the hitachis off the seca were close enough from dry setting, the mikunis on the other hand were miles low (like 20mm low), three times i tweeked them.
    Checked the clutch operation on the seca - it's not releasing. Cover off next job, need gasket first.

    20mm low? Is that even possible?

    You would have done better to leave it at .16. The clearances close up over time, and that one is now at the minimum allowable clearance to still be considered in spec.

    Well it might have been 15mm, not worth measuring, but suprisingly low all the same. Still not happy, if I'm honest, the floats as set are so close to the top of the float chamber I'm afraid it might lead to flooding. Something's not right, but I can't see what it could be. Could be I mixed up the floats between the two sets of mikunis I have,
    I'll compare them side by side. Otherwise I can't think of anything.
    Just read the clutch 101, good writup and pics, if the seca engine is worth going on with I will have to delve into it soon.

    No issues :)
    I'm really just joking about how I second guess every decision until I get more adjustments and checks under my belt.

    Bike ran well on way to work this morning and I guess no lasting issue with that missed shift a few days ago. However in going over the bike last night it looks like one of my front calipers is not moving on the pin so it's time to overhaul and find out where at least one anti-rattle device has gone because the other one lets the pad rattle a little bit too.

    I know what I'm doing this weekend....

    20mm is close to an inch! I believe we may have translation issues here.

    Nearer 3/4 of an inch, no translation issues....
    If you want to call it 15mm, I never actually measured it. Still something wrong somewhere, will re-read the piece about dry setting float levels to see if I'm somewhere near now that the actual fuel levels are close. Doesn't feel right.

    Got my bike back from the technician and he showed me the bushings to the inside of the forks and they were well worn! Glad I changed them at 73K. I am sure that they are supposed to be changed earlier.
    So I took my bike for a ride after I changed out the handle bars and clutch lever bracket.
    I have never ridden my bike without the wind screen and Damn it sure is different. So much wind, needless to say I ordered a new wind screen that day LOL.
    Also I noticed that I had acquired a nail or something of that sort and I also ordered a new front tire. 2nd one in 6 months :mad:. Better safe than sorry
    I should have these items this Thursday and have them installed Friday so I can go riding :) If the planets align for me :rolleyes:

    Better that the cooler touches the fender rather than touching the deer----

    Xj650rjc is in the barn for a while. New seat cover and strap. Paint on tail is faded new paint is going on nicely, front fender next. Carbs apart for Vapor blasting and newer hats etc. The list is getting longer each time I make 1 thing better makes other thing look bad. Might be on the road by September.

    Agreed. I'm not opposed to harvesting roadkill, but I'd rather that the roadkill not be me.
