I mentioned in my other post that I'd begun working on my buddy's 1984 VF500F. He purchased it last year nonrunning, and we went and picked it up. The carburetor was completely in bits rolling around in a box, and we're not really sure when it was last running. Could be a few years, could be a decade. The tires are 14th week of 2008. Guessing someone took the carburetor apart and just decided to move on. This thing is just making me crack up every time I see a post on reddit/youtube/whatever about "Is a VF500 a good first bike?". Anyway, it's a bit of a basket case right now, and it's got some issues that are testing my limited mechanical and electrical intelligence. But I got it running. Actually, it surprised me how quickly it fired and well it sounded when I finally mustered up the nerve to hit the go-button. I was trying to tackle items that wouldn't cost much (if any) money at all before deciding if he (we) wanted to start throwing more money into it. Adjusted the valves, and everything looked pretty good under the covers. A couple tight valves, but the cam lobes all looked in good shape. I should have checked the journals, but I didn't. I actually reseated the carburetor with the old intake boots because I was impatient and it was a Sunday and I wanted to try to run the bike. Ended up installing new ones the next day when they arrived in the mail. I'm still not good at seating a V4 carburetor. A couple other things I've done is rebuild (new seals, boots) the front brake calipers and also the clutch slave cylinder. I've got new fork seals I haven't gotten to installing yet because I've gotten wrapped up in some other problems I've discovered... The first one is the weirdest electrical issue I've ever encountered. I'm stumped, and I've been stumped for the last 8 days. Before I fired the bike, the headlight worked. Since I've fired it, no headlight. Every check I've done indicates it should work. Grounding all seems correct. No issues on the fuse block--I swapped over the fuse block from my VF500F and no difference. Additionally, seemingly randomly the electricals on the left hand control (turn signals, horn) will decide to work or not work. But never the headlight. There's no issue with the actual headlight though since that works fine straight off the battery. My hypothesis is that there's an issue with the power delivery to the left hand controls from the right hand controls. I'm really not certain what to check next since I'm kind of shit at electronics. But I've been putting my new fancy multimeter to as much use as my pea brain is capable of, and I just can't figure it out. Something must have happened when I fired the bike. Hoping the answer comes to me in a dream. Or one of you tells me something obvious I'm missing. I think I nailed the bench sync on the carburetor pretty damn close (thank you for the tips on how to do this with the paper feeler). I had my vacuum gauges out yesterday when I realized the next big issue... I saw a puddle of coolant forming under the water pump. It wasn't coming from the drain plug--it was from the lower left of the pump itself. I happened to have a new o-ring from a gasket kit and decided to see if replacing it might rectify the issue. I also have a really good looking spare water pump of unknown origin (I honestly can't remember where it came from). I just started laughing to myself when I read the manual on how to pull the water pump. Not that I even needed to pull the whole pump--just the cover. It should have been four bolts after you remove the clutch cover! Instead, you're removing two of the three engine thru bolts and jacking the engine up and removing the left side subframe all because the friggen kickstand mount blocks access to the last 8mm bolt on the water pump. .... whatever. Anyway, I put the new o-ring in. When I finished it was about 8:15pm tonight and probably too inconsiderate to the neighbors to start idling the bike even though I want to know if the fix is going to work or if I'll have to do it again and swap in the new water pump. Another major item of concern is the fact that I cannot get the left side crank case cover off. The clutch cover was a pain, the water pump was really tough, but the crank case cover... That thing is basically glued on. I tried driving a razor inbetween the cover and the engine and the razor snapped. It's really, really stuck. Luckily I don't think I need to get under there anytime soon. For the valve adjustment I just put it into 6th and spun the rear wheel to move the pistons. But I'd still like to be able to get it open at some point. I'll probably try again after running the bike to nice and hot and maybe that'll soften up whatever is gluing the damn crank case to the engine. It's pretty ratty and rusted in a lot of spots, but I think I can clean quite a bit of it up. It's too cold to paint anything right now. This is absolutely never going to be a showbike, but we might be able to make it into a decent runner. It already had the vacuum-operation of the petcock deleted too! Haven't ran it with the tank on yet, but the tank looks really good inside corrosion-wise. Also I took the horn off and haven't put it back on yet because it just gets in the way and doesn't make enough noise to be considered anything more than a cute ornament. I got my VF500F fired today (hadn't fired it since last year when I lost fuel delivery on the freeway and needed rescue) and can't believe how much quieter the stock exhaust is than my Vance and Hines, lol. The stock exhaust is much more sophisticated, noble, and refined-sounding... but my God it made me appreciate the V&H that much more. So I'm now balancing this bike with a few other projects. Namely, prepping my SV650 for a year worth of track days (why did I wait so long?!). Also the running tail lights on my VF500F stopped working after I put the fuse block in after swapping it over to test my buddy's. Because, why wouldn't I introduce more electrical gremlins into my life? I love electrical puzzles. They're my favorite. Also my truck's water pump just started leaking. So anyway, on the docket for this VF500F is: Figure out which of Isaac Asimov's ghosts in the machine I need to bribe to get the headlight on this bike to work. This likely involves buying new right hand (maybe left?) controls since I just don't know what to test on the existing controls. Run the bike to determine whether or not my new O-Ring in the water pump resolved the leak. It didn't leak when standing, only under pressure. If it doesn't work, swap in the other pump I've got. If that doesn't work, leave the bike at the end of the driveway and tell my buddy my house got robbed and they must have targeted his specific bike for the good condition gas tank. And that's all they took. Fork seals. If the circlips that hold the seals down aren't rusted through, should be pretty easy. I was thinking to just run Maxima 10W because that's what I have excess of in the house. Rear brake. Haven't touched the rear brake/caliper yet. Figure I'll just disassemble and clean it. Hasn't been high priority yet. A few more of the things I'm going to recommend be done before it gets ridden: New tires and steel braided brake lines up front. I don't want to explain to his wife that his life was ruined because of a rubber failure. It's funny. All of this started because I didn't like my kitchen sink. He was replacing his, and I liked the one that he was replacing. So I told him if he put that sink into my kitchen I would try to get this bike road-worthy. Because he knew what he was doing, we had that new sink in in like 3 hours. It's definitely going to take me a few more than 3 hours to get this bike roadworthy. But as frustrated as I get... as many Japanese engineers I curse... as many hammers as I throw (I had a weak moment changing the valve shims on my SV)... I will always take wrenching on motorcycles over housework. I replaced a pneumatic doorstop earlier today and wanted to die it was so boring. *Edit - and chain and sprockets. Forgot to mention it needs those too.
