    Got on my knees during lunch... Aye, there's a hole! (1986) Will see if the weekend gives me time to clean and inspect thoroughly. Have the ACF-50 at the ready!

    Super weird starter issue

    So I had an electrical issue to start with. And that might end in broken engine because I forgot to close this f... petcock...

    Super weird starter issue

    OMG... that make perfect sense. I hope I did not break anything like bending the valves... At lunch time today, I removed the starter and checked it was freely turning. In the end, with the help of a fellow rider and colleague, we saw the starter working by bypassing the relay but I believe the relay might be fried now after all our attempts. Will bring my spark removal tool tomorrow and see. Fingers crossed.

    Next up, forks. This was the worst set I've ever done. I've read other people's stories about bushings getting stuck, but never "had the pleasure" myself till this pair came along. Started out normal, fluid had actually been changed at some point as it was blue/green rather than the original ATF red. And, that's where the fun ended. Normally you just pull the fork halves apart with a slide hammer motion, and they come apart with a few tugs. I ended up having to get medieval on these by heating the bushing area of the lower to piping hot with my heat gun, then striking the lower with heavy hammer blows while supporting the other side with a gloved hand to eventually pull the fork tube bushing up through the slider bushing AND THE BACKING WASHER. As you can see, the bushings are ruined, I had to order replacements. I was able to flatten and dress the washers so they could be reused. Yes, that washer was flat before... Other than being dirty, the lands of the fork lower didn't look bad. After a thorough flush with brake cleaner I reassembled with the new bushings & filled with Honda fork oil. No pics, oily hands... Originally hadn't planned to changed steering bearings, but found some rust so swapped them out for a set of All Balls tapered rollers. My bearing drivers... simply an old set of races sliced with a cut off wheel & deburred. Makes for a cheap & quick way to seat new races. If the driver gets stuck, insert a flat head screwdriver and twist to expand & remove.
  6. Well, my iron horse brothers, my trip to Vietnam was killed at the starting gate. I contracted a urinary tract infection (enough of you on this site know that experience) so there will be no ride report. I have only postponed the trip but I don't know when I will be able to make it. I don't know which hurts worse, not going to Vietnam or pissing- its pissing hands down.

    Super weird starter issue

    The "click" you're getting from the stater relay sounds like a healthy, full-voltage click. If the starter relay wasn't getting enough voltage to hold it in the engaged position it would probably make a rattling, ragged-sounding noise. If I'm interpreting your short video correctly it shows you pressing the starter button twice and with each press you get a good, solid-sounding click of engagement from the starter relay, is that true? If so, it could be that there's nothing wrong with the starter relay. It would seem that you've checked off these items: Good battery and good starter relay engagement. Maybe there's just something preventing voltage from flowing through the starter windings, like perhaps the starter motor's path-to-ground (negative) wire has come loose? Or maybe there's a problem at the main grounding lug on the engine? But.... it's possible that your situation has nothing to do with the electrical system: "More strange, it's impossible to jump start the bike because as soon as I release the clutch, the bike stops violently (like something mechanical preventing the bike from moving)." This statement is a bit worrying. You mentioned yesterday that you accidentally left the bike's petcock in "prime", I guess it could be possible that one (or more) of the cylinders is full of gasoline and you are experiencing Hydraulic Lock as a result. Just a thought.

    Just a little plaque buildup on the old thermostat... Discard and replace with new tstat & o ring In case you were wondering, or in denial, about your vintage bike needing rubber even though it has low miles - here's your evidence that yes, it does need replacing!

    Tires!

    METZELLER ROADTEC 01 second set of them Rode them last year on a long trip with passenger and bags in cold and wet conditions: super happy, lot of confidence on the wet, no issues changed at 15k I come basically from Pirelli Angel GT : ROADTEC are a step forward as touring tyres not as good as the Diablo II on dry/warm conditions but that's obvious Better in every aspect then originals Dunlop D222 which I hated for less then 6k

    Super weird starter issue

    Unfortunately, I don't think that's the battery. I just installed a brand new one (put the acid inside around noon, installed it in the bike at 03:00PM). I just don't understand why I cannot push start the bike. I will remove the starter today and see if the output axle can rotate freely.

    It is actually a Honda press release given to explain what was new on the 5G. The 5.2 shows two different power ratings(106 and 110), it looks like it’s at different standards. I thought I would add this as well to compare to the old 750: 1998_VFR_INFO.MOV

    Interesting reading for sure, but something is not adding up. I am not interested in max power figures, except for comparison purposes. In that Honda doc, they state the 5.2 makes 106 PS and the provided graph, while not including any figures shows the 5.2 making quite a bit more than the 5.1 they show for comparison. In fact from that Honda graph, a very rough estimate would put the 5.1 at no more than 100 PS. Yet figures I have for the 5.1 state 110 HP. Now I realise that PS are slightly bigger than traditional HP so the number would be slightly lower, but certainly not 10%. Those 5.1 figures are not from Honda literature, but from some press info. However, it is almost certainly simply copied from Honda's own literature at the time. So either I'm missing something here, or someone's being economical with the truth. BTW, Honda's figures for the Gen 6 are 107 PS max. So certainly same ballpark. The 8th Gen dropped to 104.

    Hi Ken, 5+6th gens have outlets in the same place & the exhaust pairings are the same. But on 5th gen the #1 cylinder (rear left) header runs around the outside of the #3 header, making it longer & accounting for the disparate vacuum readings when balancing the TB’s. On the 6th gen Honda corrected this, by bringing #1 header under & inside #3 header thus making them the same length, but that meant they had to cross the front header pipes to keep the port pairing the same. So 6th gen have crossed front & rear pipes & 5th gen have no crosses. The port pairing on the 5/6th gens gives the best exhaust scavenge effect. But the gains are not great, due to the odd firing order. A correctly sized header with 8th gen port matching should work just as well. Looking at this new header it appears to have stepped or a poor mans tapered header which is all the rage in MotoGP systems. For reference the TBR system on mine added 8hp after a little fuel adjustment, but was good for 6hp without fuelling update. Power went from 112hp to 120hp same configuration, same dyno, all that changed was the exhausts from Motad to TBR. If the 5.7kg mentioned is just the header, then that’s heavy, compared to TBR at 4kg, but lighter than stock, especially if you have a cat exhaust which adds 2kg by itself. YMMV

    Winter glove recommendations

    I have been using Five WFX series of gloves for winter duty for about 5 years. They have been performing very well for me without using heated grips for my winter commuting down to -10C Personally, it's always the top of the hand and especially fingers that suffer so heated grips never really did much for me.

    Though not cheep I expect a pair of Held cold champ gore-tex gloves to be delivered next Monday. I don't think cold hands to be a problem this winter. I'll report upon arrival. https://www.revzilla.com/motorcycle/held-cold-champ-gore-tex-gloves

    Now that is a first for me to read. Good find there, and yes, explains a bit or two, then on the last page about the clutch. yes, interesting.

    A rough idea is all you can hope for and will be good enough. You have to keep in mind that the 00/01 had a few changes from the 98/99. When the 00 introduced the cat, the exhaust headers were made of smaller diameter to help heat up the coverter as quickly as possible. This in turn requiered a different fuel map to oveturn loses from the restrictive pipes and bring HP back to were the 98/99 was. The press release at the time stated that fuel efficiency was up on the 00 because of this. So my educated guess is that the 00/01 will produce more HP than the 98/99 with the 98/99 headers. So seeing an increase of HP using these new pipes on an 01, doesnt reliably mean that you will get an increase of power on a 98/99. Don't get me wrong, I'm happy to see a good set of pipes being made, and will seriously consider getting rid of my Delk's on my 01 if power is up. The Delk's are a nice looking pipe, but the collector is an El Cheapo design that hasn't got a hope in hell of being a performance pipe. I got mine because the original pipes looked like shit, and had a couple of dings in them and couldn't find a 98/99 set.

    It's probably god enough for most people's purposes. Same bike, same day, same dyno, and same filtration (only difference being headers), should give a good enough guide as to real-world gains from the aftermarket header. Oh, and if we can get the measured weights for the standard and aftermarket header, that too would be handy...

    Yup, air filter will go in during service - before any dyno runs. Same with end can. No fuel management I’m afraid. Jeff is too busy to mess with that sort of fine tuning. Best we can expect is a simple dyno run before and another simple dyno run after fitting the new header. No dyno tuning - just dyno measurement. Frankly we are lucky to get this much from a very obliging and generous supplier. Stray

    Had this exact issue in my “other” bike - dead battery. Fired right up after a charge. As as it gets colder a marginal battery will start showing its weakness this time of year. Either charge or replace.
