  1. You are the ultimate ANTI-hack! You do everything the way most of us wish we could. Thank you for letting us tag along!! I'll admit that I check this thread sometimes twice a day to see if any new progress is posted. Will you be using an electric fuel pump or are you going to try gravity feed with the single inlet on the left side?
  2. What I meant to say is that it was you who built the belt-o-ceptor, a legend among us VF500F owners because of the astoundingly high mileage. How many miles when you sold it to your buddy? Most don't make it past 20k miles.
  3. Hi Busy, I have a question for you completely unrelated to this thread (sorry). What happened to your 100k mile BELT-O-CEPTOR? Did it finally drop a valve or? Did you ever replace valves or valve springs on that thing? That was you right? If it wasn't sorry.
  4. Actually, it takes water-melon sized to do that today given the weakness of the old valves. Back then, raisin-size would have been more than enough wringing out the new engine.
  5. Wow, you have bikes like that collecting dust in containers? Living the dream right there... Anyway, just in case you're curious and hadn't seen one opened up, this is a stock collector picture I pirated from that aforementioned site.
  6. I have never seen one dyno'd at more than 53 but that was from stock magazine tests about a million years ago. I can't say I've seen anyone dyno one of these in good condition in recent decades. I've only seen a couple with very low numbers on engines in poor condition. I will mention, IF I remember correctly that a fella named Jamie Daugherty (an ultra expert from another site) who used to race these, mentioned something about the stock exhaust collector and that it isn't a terrible design for this bike and that sometimes attempts for more free flowing exhausts have come up short or something along those lines. They had a pretty extensive discussion on it. http://vfrworld.com/forums/showthread.php/30249-VF500F-Aftermarket-Exhaust-Systems-from-Back-in-the-Day We hope you nailed it with your design on this one and perhaps your porting and richer jets can be calibrated efficiently enough for you to make good numbers. It'll be very interesting to see what you end up pulling.
  7. This is truly an epic thread for remaining vf500f fans worldwide! Are you planning any dyno pulls? Thank You!
  8. Had to "google" that one! Well, the basic frame and the engine are pretty legit vf500f but I hear you on the rest of it. Different "handles and heads" but the core is still a vf500f in spirit. Besides, all the NEWer handles and heads are better than the originals right?
  9. Things are getting exciting. Can't wait for a shot of the entire bike. Nice idea on the extended idle screw, definitely beats burning your hand on the hot valve cover or reaching in there with a glove. Thank you Sport!
  10. Very impressive progress, can't wait to see the final product. Changing up the transmission has seemed to be the most complicated aspect of your endeavor so far. I hope everything continues to come together well and that those God-forsaken valves hold up for you.
  11. Yes, nice to see you back. You're right about the cam timing marks, they've never looked dead on for me like the pictures show. However, one tooth adjustments either way makes a big enough difference that you know it can't be right but you get it as close as you can with the lobes pointing (viewing from the left side of the engine) the way the pictures show and the upper marks on the outside of the cam sprockets lined up (as close as you can) to the edge of the case. It won't be perfect but get them as close as you can and you should be fine. I've never been wrong...yet.
  12. Hey Sports, no word in almost 2 weeks! You spoiled us with your impressive and steady progress. Hope everything is going well friend.
  13. Just as an FYI... I bought the 84/85 kit (dual springs, retainers, cotters, spring seats) for just little over $800 (USD), they looked great but were not the right size, too tall and too wide. The owner refunded my money promptly, apologized and asked that I send him some old samples and that he'd have them ready for me in about 2 weeks. I just elected to go with some springs I got from CMSNL NOS last year instead. They only had about 1500 miles on them before a valve broke/dropped. Anyway, doing a complete and correct job on the heads alone with new springs, valves, guides, retainers, cotters, valve stem seals, head gaskets, various o-rings, machine shop labor, etc easily exceeds the value of even a mint entire bike. Not cost effective by any means but if you want to ride one as reliably as you can afford, it'll cost you.
  14. sorry to hear of your troubles, I've been there and done all that with a dropped valve after rebuilding the heads. Anyway, you must pull the engine. If you're going to try to keep this bike alive, you might as well learn how to do that well. I'm pretty sure you can pull the front head with the engine in but the rear one is really tightly in there. Besides, the rear, top engine mount is part of the rear head sooo... it's just so much easier working on a head without having to maneuver around the frame trying to find the best angles to hook up wrenches or anything. You can still buy new valves, they are pretty easy to find (partzilla, ebay, many places still carry them). Luckily the exhaust valves for the 84-86 are all the same, the intakes did change in 86 though. If your valve was bent then your guide is probably trashed and putting it back together with a trashed guide will not last very long so you'd have to have a new guide installed. A machine shop should be able to help you with that along with cleaning up the seat for a new valve. You'll be relegated to aftermarket head gaskets as well, there are no OEM's out there that I know of. Plenty of aftermarket stuff though, they've worked fine for me, I just found that torquing them (and re-torquing after a couple hundred miles) just a little over spec works best, otherwise you might get a little coolant seepage on the edges... Here's a thought: if you have no real love or commitment for one of these, it's my humble advice to look elsewhere for riding an old(er) bike. Pick up an 87 of some type or younger... the headaches will seldom cease with one of these. The only reason I keep mine alive is that I bought it new when I was 18 and I'm almost 52 now.... so it's just part of my life. Best of luck, you'll most certainly need it.
  15. I actually used silicone hoses from the 600 Hornet, just had to cut a little bit but I eliminated the steel down-pipe with a hose similar to what the Hornet has. Looks a little strange in red but it works just fine. They were only about 20 or 25 bucks on ebay and come in black too. Of course, with a larger radiator, you'd probably have to cut em up a bit.
