Final video in the Magna repair series, I reinstall the carbs, do a valve clearance check and synchronization. It runs so much better! Like a new bike!
I just finished the valve clearance on my 85 Magna V45. Very much learning as I go here; not a mechanic, although I pretend to be one sometimes. This was really helpful to get a visual, and just wrap my head around it. It went so well, and I'm very happy with the results. I'll be syncing my carbs too once I can get my hands on a manometer. So I will be back! Thanks a million :)
Just to let everyone know Dave Dodge passed away just before Thanksgiving 2023, he was a wizard when it came to the Honda V-4’s. My son met him last year, and we spoke to him several times about these bikes (we had 4 V-45 Sabres at that time), he had an amazing vast knowledge of these bikes. After he passed we spoke with his sister, and helped her get a lot of his shop cleaned up, he will be dearly missed in the motorcycle community.
Much thanks for the info. Wish I had seen this before the first time I “cleaned” the carbs on an ‘82 Sabre I recently bought. It would idle for a second and die. I just pulled the carbs again for more thorough cleaning (wasn’t much easier to pull the second time). Thanks again for sharing your knowledge👊
You are correct about Dave Dodge. When i owned my Honda V-65, i talked to Dave many times on the phone over the years. Dave's knowledge of early V-4's is vast .
I also have an 82. yes I've had them out. Used ratchet straps to get back in. I bench synced them thought that would be good but maybe I need to get synchronization tool.I have 43,000 seems to run good though. cams show a little wear.
Awesome. If you ever have to take the front cam out, there is a very specific procedure on how to time that cam (only the front 2-4 cylinders) on just the 1982 model. The cam is actually set up 45 degrees off the head surface to the timing mark. The rear cylinder is normal. If you put a cylinder 2-4 cam out of an '83 VF750C, the cam timing is normal, in line with the head surface. It's really weird. Honda has this convoluted procedure to set the timing on that cam for the '82, but there's a much simpler way. Cheers.
I remember a couple years ago he was sick, like down for the count. This was before the ‘Rona stuff. I ordered something from them and was talking with his wife about it. I’ll try and reach out to her with condolences.
Will it even pop off? Or is it completely dead? Is it an 82? Were the cams removed especially on the front 2-4 cylinders? Gonna sound dumb but check the kill switch if it’s original. Power passes through it for ignition and it’ll crank even if the coils are getting intermittent power. That switch is a convoluted mess and a voltage drop under crank load could cause a no start.
Ah. Good question. On the Magna and a few other designs there are screws into the aluminum just behind the carb holders (insulators) on the head side. They’re M6 on these, others are M5. The carb tune kit and others comes with brass tubes with threads on one end to thread into those holes. Those are the vacuum ports. Carefully take out the screws. There should be aluminum sealing washers behind them. Use the washers from the brass tubes and screw them in. Just use a pair of pliers to snug them. Hook the synch hoses to the tubes. When finished return the screws with the seal washers back to the each hole.
Great video brother... taking the carbs off gets s little easier each time I can practically do it in my sleep maybe 10 minutes to remove and another 10 to install but I have a 1983 sabre v45 should be about the same...I need to sync carbs but have been avoiding it... this video has made it seem very doable to me... say is that manometer you used able to be used for a 2 cylinder or only 4 cylinder like is is universal???...
@@josemares1439 leading link front end. Because of the sidecar. Look up leading link and sidecar in the Google machine and you can learn all about it. And yes, I fabricated it completely in house and at that time, without any machine tools except a vintage Taiwan 1980 drill press.
The early V4’s pulled top end oil off the transmission via steel lines with Banjo fittings. The theory was that the early engines top end wear issues was related to oil starvation. The bypass kit takes oil right off the filter base and sends to the top end directly. It was a kit Dave Dodge sold. I recently learned he passed not too long ago so they’re probably not available anymore. The jury is still out on that theory, however, depends on where you read it whether the bypass is necessary at all. I chose to install one right out of the chute. The forks are a home made leading link suspension which is too complicated to explain here, look that up and you’ll see what it is.
Hello Moto resto have you ever had a v45 magna that was washed took water in through the air intake and then wouldn't run I have good compression spark and fuel check the timing new coils new plugs it will not run or fire at all do you have any thoughts on this issue or anyone else out there thank you
Thanks for the response it is a 1984 Honda magna VF700 and I do have power to the coils but it still doesn't fire at all and the coils are both brand new and new spark plugs
Would it have to turn over a few times for to hydrolock because when I went to start it it was it was just like bumping a starter it wouldn't turn over to like pull the plugs out sprayed out the cylinders with compressed air and WD-40 then it would turn over as normal but still wouldn't run
Well, if it has compression, fuel, air and ignition, it will run... it has to. So, one of the four isn't there, or isn't there in the amounts required. You need to go back to basics and re-verify everything. Flooded engines I have not dealt with, but again, if it has all the necessary things for running, it will run. The fact it doesn't, you have to go back and check everything. Something is being missed. Cheers.
Didn’t need to. They weren’t separated. And previously synchronized with my Carb Tune Pro. You only need to bench synch when multi carb racks are separated. Or an unknown baseline.
