    Yep. Right between the 2. I know Gilford (helped a client buy a house there...nice area). Thanks for the info. I did find part numbers but figured a front can should be swappable with rear (intake to intake, exhaust to exhaust). I may have a bead on a parts bike and will visually check the cams before buying as 2 bikes with same problem not desirable.

    You kids and your language.... Here's a wonderful piece of Graffiti that says it all... simply, concisely and accurately.[​IMG]

    I wish all graffiti made this much sense.

    I've ordered a used head with cams and lifters attached. I will let you know how things go.

    So back to the bike.... Rear head I ordered from a seller in Montreal arrived yesterday. Looks good, or at least, better than the cam and followers I will be replacing. I thought this was going to be a simple job of swapping parts BUT no, looks like the engine has to come out (as the follower retaining bolt won't clear the frame. So, either I remove the engine or swap heads. I think swapping heads may be simpler in the long run so I don't have go hunting for exhaust gaskets, etc. The valves and seats look good with the new head and I can't be sure there was not a bit of interference with the valve on the old head. A question though: the cams look much, much better and the followers also but they do have a slight amount of wear evident. Is it normal for there to be a bit of cupping and can anyone tell me if the followers (or are they called tappets?) are all the same? These have #4, #7, and 2 have #8 stamped on them but look identical. Thoughts anyone?

    Thank you. Now, the hunt for economically priced gaskets.

    I think some folks on here would tell you that they had issues with some of the cheaper gaskets, where as some others proved more reliable.

    Matt and Jim in particular may have information on which gaskets were more reliable than others, if you search this thread, I think you may find the reference, buying the right ones may save you no end of grief from failing head gaskets...

    if its not in Matts thread, then its in Jim's:

    Are you saying that the "new" followers are slightly cupped? Not good.

    Followers are the forked items. Tappets are the threaded posts with the lock nuts that interact with the valve stem.

    Post #320 in Jim's thread is where you'll find his in-depth review on the head gaskets. Page 16: https://vfrworld.com/threads/jims-400-00-1986-vf500f.57065/page-16

    I'm looking through my old emails to try to find a Vesrah part number for the full engine gasket set, which is what I bought. I wouldn't mind grabbing myself another since I'll be going through a buddy's VF this winter and could use all the engine gaskets. I'm failing to find it though. It was quite reasonably priced too, darnit.

    I have also seen many vf500 gaskets advertised but the vf750 seem a bit harder to find, or at least, they are available but the sellers want crazy fees for shipping. Should it cost $40 usd to mail a thin package to Ontario? Probably not but the sellers aren't interested in discussing shipping costs and there is a limit to how much I will be gouged.
    Captain 80's, yes, followers are slightly cupped but much, much better than the one I am replacing.

    I may purchase the kit and have it shipped to a u.s. address (that is at least free) and then have it redirected. A bit of savings but this is a winter project so no rush.

    Sorry for the delay in following up. It's been a weird couple of years. So, I sent off the rockers to be profiled (Walkerton Ontario, about $7 each) and the cams to be cleaned up and Parkerized (spelling?)... which, I believe, is an infusion of lubricant. The cam specialist did not recommend hardening as he has worked on many of these in the past. Put it all together and seems fine, except for some pesky oil leaks *and I changed every gasket and seal I could get to).
    I'm taking short rides, and although I have balanced the carbs ( mercury sticks), it still feels a bit buzzy so I will check the mixtures again.
    Going for short rides over the last week, I seem to hear more chattering than I think is normal, but as I have no other 84 bf750f to compare to, no idea if it is normal.
    I had to rebuild my tach and speedo needles as they fell off... found doner needles from a cheap china-cluster as even used clusters seem to be stupid expensive... and the fragile needles could become an issue again. While riding today, I noticed the small black screws holding the tach dial fell out and the tach dial started spinning. That was an odd scene. I am attaching a link to a video and you can hear the tapping at idle. is this excessive? I am planning to check teh valves again and also the condition of the rockers just in case.
    Safe ride to you all. https://www.youtube.com/shorts/Ck5trmAFNA0

    I would say yes, that does sound excessive to my ear.
