  1. I'm not even retired and I don't have enough time to put on more than about 1k a year. 2 kids, a house that I built, and a very, shall we say, selfish/vindictive/physco wife does that to you. The wife bit will be ending soon but not the kids thankfully. 

     

    2024 is going to be different. 

  2. @Skids looks good to me. I would do the electrical connectors purely due to the age, I see you have this listed already. Do you intend to change out the most likely stock RR? I got a CBR500 one which is a FH020 and it´s working perfectly, I used the Metri Pack connectors for the stator connection also instead of hard wiring them so I can remove it if necessary. If it gives you peace of mind then check the valves, won´t harm anything.

     

    Enjoy the servicing its a great winter pastime when its not possible to ride 🍺

  3. Can't help with the rev counter as that goes into electrical territory which I'm crap at but there are some very knowledgeable members on here that help others a lot!

     

    I would suggest you check the speed sensor which goes onto the front sprocket nut. This is a plastic piece that often doesn't get fitted back on to the nut properly and rounds out causing speed reading irregularities. 

     

    Good luck.

  4. No never seen  this. I have a 98 and it doesn't lean over that far on the side stand.

     

    You need to investigate further, either something isn't tight or its bent.

    OR

    the previous owner fitted a shorter side stand because he lowered it but that wouldn't explain the movement you're seeing.  

    Hth.

    Keep in mind that the bearings are designed so that the spacers locate everything in the correct place when you tighten the axle down. That's why you tighten the bolt on the right end of the axle first and then the clamps on the bottom of the forks. The wheel is located to the right side bearing that seats the outer race against the shoulder, and the other outer race has a more relaxed fit to allow it to locate relative to the inner race. This helps prevent it from being side loaded due to install error, and also due to thermal expansion. The manual tells you to install the right side bearing first for a good reason. Since it is your right side that is loose (assuming you haven't installed the wheel backwards...) I think you are fine using bearing retainer on that bearing as it goes in first and seats on the shoulder. I've used 609 numerous times on industrial and automotive repairs and it works great. If the bearing is flopping around loose and the wheel is wallowed out it won't fix that, but the difference between having to tap it lightly and falling on it's own is very small and not going to affect the wheel running on centre. This is what it is intended for. You don't need much, you don't want it squeezing up the back shoulder and into the bearing. I would clean everything well to be free of oil and wipe a thin film in the bottom of the bearing bore, only where the bearing seats, or you'll just push it all to the bottom anyway and have too much. Leave it to set up, unless you use Loctite primer, before installing the spacer and other bearing. Don't keep driving the other bearing in once it contacts the spacer or you'll undo what you are trying to fix.

    Thanks @Dangeruss

    for the tips and advice.

    I decided on the 641 as its suitable for disassembly which some of the others aren't without a great deal of heat which I don't want to inflict on my wheel.

     

    After more research , I will be removing the bearing and doing similar to what you suggested in contrast to my previous process above.

     

    I took the wheel off again today in preparation. I used a drift from the other side to gently push it out until I felt resistance, then I turned it over and I was able to, forcibly, push the bearing back into its seat with my thumbs. It's not flopping about and needs a good push to force it back down but that's not right, it should be tight in the pocket or the whole oscillating forces will probably make the pocket even wider/more oval.

    I'm pretty sure now that the pocket for the bearing has been expanded by a clumsy, cock-handed attempt at removal or fitting by yours truly. Even though I've done this many times this is proof that anyone can cock up anything.

     

    I'll report back on my wheel escapades!

    From what you have said if I read it correctly one bearing fits as you might expect but the other is a tight fit as you start it, then goes loose once far enough in to seat against the inner bearing spacer. If that is correct it sounds like the spacer is too short. One of the Kawasakis I used to have had that setup. The bearing on one side was a traditional fit to a shoulder in the wheel, the others depth was controlled by the spacer. After powder coat & a couple of months between removal & refitting I used the wrong spacer & the bearing floated inside the wheel. Once I realised my mistake & got it out I was able to put it in correctly. 
     

    Bearing goo will not work unless you have a means to centralise the shaft to the wheel exactly. Check you parts are all correct ! Wouldn't be the first secondhand parts that came with wrong bits installed ! 

    Thanks @Mohawk for your input.

    The parts are correct, been in use some 15+ years now and only now a problem.

    This is a result of the traditional way of removing the bearing, knock it out and inevitably damage the seat

     

    More effect is using a Rawlbolt on the inner race and pull it out, also the cheap way of getting blind bearings out 

    Again, appreciate the advice @Thumbs.

    I think you're right on the drift method to remove the bearing previously not being as exact as I thought I was doing it ie. slowly around the edges.

     

    641 ordered and on the way!

     I wonder-would it matter if the wheel bearing wasn't snug inside the rim?  The spacers will hold everything in place, right? 

    I made sure the bearing seats were clean before fitting, I had also taped off the wheel myself before powder.

     

    I think it would matter if it has any play because even though the spacers hold it in place laterally the bearing can still move up, down, sideways and with the forces of suspension etc it would rattle it around eventually shaking the bearing to bits. This is my understanding and suspicion anyway of what happened to the old bearing.

    If you had the wheel raised off the ground, even go ahead and remove the calipers, tightened up the axle before the material set, and use something like the stuff that the Honda factory puts on cam gear fasteners that turns to rock, then ya it would center and hold the wheel. 

     

    That would be the 648 which is a permanent adhesion type of compound, I don´t want to use this as it would be a nightmare to remove the bearing again in the future.

     

    I´m still researching how I´ll do it but the first idea is not to drive the bearing out again but leave it in and apply the loctite 641 around the circumference of the bearing outer race. This 641 is supposed to have a low viscosity so I´m hoping it drains down where there are any gaps. It sets in 10 minutes, fully cured in 24 hours, so I would have enough time to then quickly reinstall the wheel so it sets in the correct position.

    Ducky job though. Hope it works out for ya Bren.

     Very much my feeling too. Thanks. I´ll update my success or failure!

  9. Hi All, looking for the collective wisdom on this.

     

    I have the SP1 front end on my bike with an SP1 wheel, when I got the wheel powder coated a few years ago I put new bearings in. I felt something was off a few weeks ago and checked the bearings and sure enough one was noisy and rough. Interestingly there were drops of water under the dust seals and the bearings on both sides when I took them out. I don´t generally go out in rain anymore and I haven´t washed it in a while. On this wheel the right hand side bearing sits deeper into the rim than the left, right wheel spacer on that side is also longer. When driving the right side (deeper) bearing out it seemed to fall/plop towards the outside edge a bit before having then a significant interference fit and I had to tap it out all around the edge as expected. When fitting the new bearing there was an interference fit at the beginning but then once just below the edge of the wheel it seemed to almost fall down to the bottom of the pocket, left one had to be driven all the way down to seat properly.

     

    I´m wondering, and worried!, now if my wheel is screwed or does this sound normal?

  10. That's nice!

     

    I see you've blocked off the headlights and put some spots where the indicators reside, are they suitable for night time?

    I ask as I had an idea for my gen 5 to pull the huge indicators, make a small housing out of fiberglass and put some small spots in there as ancillary lighting, indicating would be taken care of by mirror mounted indicators ala CBR1100XX Blackbird.

    I just haven't found any small yet powerful enough that may work.

    Have a link?

  11. Whatever you do don't torque them to the same as ball bearings, one owner many moons ago cracked his head doing exactly that.

    When I did mine I torqued them down to half the ball bearings value to seat them, then gave a few gentle turns for good measure. There was a lot of resistance. Then I  backed the nut off completely and torqued again to a very low value, I want to say 9 ft/lbs but can't be 100% sure. I did the rest by "feel" (not helping I realise). Check for the whole lot flopping over to one side too easy, front wheel off the ground of course. It's easy to tell when they're too tight as they won't move much doing the procedure again and there will be a resistance you can feel. You're looking for the bars to move from center to the side with a gentle push, while not flopping over when you just lift the front off the ground. 

     

    I think once you start doing it you'll feel the differences between loose and tight.

     

    Edit, if your not comfortable doing it get a mechanic to do it who will let you watch. You'll learn something new and be prepared for any adjustments in the future.

  12. You would have enough power to keep it running with what you've got, the rectifier change is something for later.

    It just sounds like it's not getting fuel to me, or air. Would the ATF you sprayed the K&N be too thick and restricting air?

    You may have a kinked fuel hose from the tank that won't allow enough fuel to flow. As you just lifted the tank to get at the air filter this could have happened.

    Good luck with it.

  13. Your voltage falling to 13.5 is the first suspect. Generally at 5000rpm with a good charging system you should have 14.4 ish. Get a FH020AA from a cbr500 or Yamaha and fit that, that'll fix your charging for a start.

    But why your engine only runs for short periods, that shouldn't have anything to do with the rectifier at that point because it's going off battery power anyway. 

    Sounds like a fuel pump problem or pump power issue. It's not getting power to keep running. Did you check the fuse?

    3 seconds or so priming is normal.
