    Yea, bike was running ok with the exception of the 2nd gear issue.

    Ill be sure that everything is "clean" in there, thats for sure.

    Its that Nut that has me perplexed, there just are so few nuts used internally for that engine.

    Of course I have to now assume that shattered washer between C2 and C3. resulting in C2 moving side to side is actually the main cause of the ratcheting in 2nd gear, while there is a chip in one of the M2/3 dogs, it doesnt seem big enough to cause that issue. Some of the dogs on M2/3 were slightly rounded so maybe the loose C2 + the rounding of the dogs conspired to cause the issue. No real way to test this until the bike is running under load again. Sure I can move the shift drum by hand when I have the cases back together to ensure it will shift ok, but its not gonna slip or ratchet with me moving it by hand.

    Tranny is repaired.

    C4 gear swapped for a spare - rounded dogs
    M4 and M5 swapped for a spare - chipped dogs
    right side shif fork swapped for a spare - heavily worn
    as it happens my M2/3 was still ok. (not chipped), and thank goodness for that as the one that got sent from Japan was wrong. its a 17/20 gear set and the replacement was a 19/22 . Ebay seller has since disappeared.

    The only "odd" thing was I debated changing the centre shift fork. no visible ware on it (so I didnt swap it), but I have 2 spare sets of forks, one has the same centre shif fork as I have and the other has a different style centre fork. one used the tips of the forks to exert pressure to slide the gear, one used the "trough" of the fork instead. I know Honda upgraded alot of shif forks in the mid 80's after they had issues, so im not sure why this one is different ...any way, since my centre one was ok I thought it best to leave it as is.


    Here are the 2 different styles of 6C centre shift forks. (the one in the bike is the same as the one on the right, no its not worn despite how it appears). Anyone know whey theyre different ? you can see the contact zones are opposite..

    Weird. Can you compare engine numbers and see which part came out of a later unit?

    Was it that mashed stop washer that caused that massive wear?

    The thinner looking fork is possibly stronger, shifting from the base rather than the tips of the fork

    Well I figured out the mystery. My 2 "spare" VF1000R transmissions are quite different.

    the one thats different to the bike im working on:
    -The M gears have slightly thicker teeth on the M4 and dont have a small bevel cut M5
    -The C shaft is smaller, so none of the gears or washers fit my C shaft, the c4 on the different one also has a bushing sleeve, vs needle bearings in mine
    -Different center shift fork

    So..... as I looked closer (double checking my work) I had to swap the M4/5 back out for the other spare ones, the C4 was fine as I took it from the identical spare (the other C4 wouldn't have fitted due to shaft size).

    Thanks goodness Im taking my time to double check.

    its odd that the 2 transmissions I have for spares are different, on first look, you cannot tell, the whole shaft assemblies are fully interchangeable, its only when you look at the individual parts you can tell. Maybe one is an earlier or later model ? I dont know which trans came from which case as it was already stripped wen I got it. Maybe one is from a VF1000F (although the cases are all VF1000R)

    did a dry run putting the cases together and clicked it through all the gears -- Seems all good

    Will spend the rest of today cleaning & painting parts (Countershaft Cover, Water Pump, Oil Pan etc) and Ill start to seal it all up again tomorrow

    lots of gasket residue to clean off the side case covers etc cases too.

    Thanks a lot.

    Tomorrow Ill mount the swing arm, triple clamps, forks and some other goodies. Maybe even get her back on her wheels.

    That clutch fluid is nasty too, it needs flushing/changing

    I’m going to replace the needles in my swing arm next year

    The rollers are 20x26x30 and I can buy them all over the place, even though they are NLA with Honda,

    The brake fluid in mine was 10% water = useless

    Needles in mine are ok, I built the bike 2 yrs ago and its sat in the shop ever since.

    I will have to spend some time cleaning epoxy and PC paint from the frame section where the swing arm bolts go through. this frame was powder-coated prior to this paint job and the idiots didnt mask that area very well. the frame I just took off was the same, I had the jump through all kinds of hoops to get the swing arm bolts Out of that a week ago it was so tight. That could take the entire morning depending ho much is in there.

    I have had car wheels that would not go on because of powder coat being far to thick

    And one set that were forced on by the refurb company, that we had to use a 6lb club hammer and a big block of wood to get off

    Sometimes I wonder about these folks, they have one job....,,,,

    I have never been impressed with powder coaters. And WHEN they fuck up, you're left with the mess and work.

    Looking good, by the way!!

    Todays progress. Not show in the pics is some other things I got done, all the shift linkage is back in along with the drive gear and oil pump gear and chain, I also installed the drive sprocket cover and the clutch slave. Decided to break for the day, Im not rushing this.

    Rear wheel is just in temporarily to aid in the install of various bits in the side cases. It will come back out when I get to installing all the "gubbins" at the back end of the bike

    Tomorrow, the clutch assembly, starter clutch assembly and the stator/flywheel.

    I may fill up the coolant tomorrow and if there are no leaks at the new O-rings I can get the Carbs back on tomorrow afternoon if time permits.

    Well, its alive.

    Its up and running, but I may have a small oil leak at the pan. I used a new Oring and case seal there, but maybe it got pinched. Ill re-assess that tomorrow.

    Aside from that, I had a minor fuel leak which I resolved and also #4 cyl was not getting fuel so I swapped out the carbs for another spare set and that solved that issue.

    Tomorrow ill also get it off the stand and put her in gear for the first time and see what ive got.

    No road tests here, were are covered in light snow.
