- 1998 Honda Valkyrie repairs Video #2. These carbs were a mess, missing hoses, vacuum lines either missing or improperly connected, EVAP/Emissions partially deleted, which contributed to the problems. Did we fix it? Watch and see!
For Valkyrie parts (depending upon stock) check out Rich at Red Eye Technical, LLP; without whom we'd never be able to do these Valkyrie jobs as economical as we can.

Enjoyed the video Tom,, so you. Like the valkary flat six. RIDE SAFE OUT THERE!
Love the sound of the flat six, great job!
Your content is top shelf. Thank you! I picked up a barn fresh Voyager XII and your series on that has been priceless.
I get nightmares from that bike. Good luck. :)
Man, what a project! I went through this on a '78 Goldwing (GL1000) about 29 years ago. Even with close to $300 in complete carb kits, floats, needles, and seats, it never would idle properly. I specialized in automotive electrical and carb repair at the time, but the Honda CV carbs are on another level.😜 I finally built a common airbox with runners to the individual cylinders, with a Weber 32/36 DGEV carburetor, and it turned into a completely different bike! It idled dead smooth at 750 rpm. and even though it lost a little bit of top end, it was predictable throughout the rpm range, and the fuel mileage jumped to around 46 mpg after I got the jetting just right!😊 Unless you're building a show bike, I'd never recommend tackling these carbs. Nowadays, it would probably be even better to set it up with Haltech programmable EFI, and get rid of the carbs altogether. With the crappy ethanol fuel we're dealing with now, you'd probably have to rebuild these every couple of years just to keep it running properly.😳
I saw only one of those conversions on a GL1000, maybe it was yours I don't know, here in Florida on a Vintage Japanese Motorcycle Club event, probably 10 years ago up in Ocala. The guy popped the fake tank cover off and I was like, woah.... no kidding. It ran perfectly and sounded great. Frankly, I'd love to try that mod someday. Cheers.
@@MotoRestoFL I did all this back in 1995 actually, before the internet and 3D printers were a real thing around here. (I'm in N.M. btw) The design was fairly simple except for working out how to keep the runners on the OUTSIDE of the manifold box to alleviate any restrictions or weird flow characteristics. I made the lower part and sides of the box in one piece, out of 1/8" steel, and drilled the holes while it was still flat so that they were actually a little below the bottom corner of the box when it was folded up. There were some weird compound angles on the runners that took a lot of filing and fitting, until I could actually tack them in on the bike, and then removed the whole assembly to finish welding it. I drilled the top plate for the carb inlets and mounting bolts, and welded nuts underneath for the mounting bolts before I welded the top plate onto the box. I also made a custom throttle cable eccentric for the Weber throttle shaft, so I could use the double throttle cables and a fairly light return spring, and not worry about it getting stuck open. It actually was much easier to twist than with the stock GL 'jungle gym' throttle linkage!🤣 Overall, I think I only spent about a week designing and fitting everything before I welded it all together. I was really impressed with how well it ran afterwards, and once I fine tuned the jetting, it ran even better! I rarely had to get into the 'secondaries' on the Weber 2 bbl. to get into traffic or whatever, but you definitely knew there was something different under that fake gas tank with the howl from that Weber, when you grabbed a handful!😄👍👍
Beautiful bike, glad you got it sorted out and it sounds great.
I am TRULY AMAZED !!!
Amazing... 👍👍
Awesome ! Thanks ! 👍👍
❤Sounds Awesome 🎉
I had bad luck with the k&L float needles on my zg1000. Random flooding issues. Paid the price at 45 bucks each for oem. That hurt but two years out and running correctly.
Most of the time they work great. But I gotta go with what the testing shows at the time of the work being performed. It’s the only metric I have to go off.
You have the patience of an oyster, my friend.
Thanks, the other day on this old lawn tractor I bought, there may have been a high-velocity flashlight launch episode. Maybe. lol
I really appreciate all your videos. Just got done doing a set of 97 Valkyrie carbs and pressure tested them like you did here. My carbs leak down very slowly after setting pressure at 5lbs. It takes6 minutes for them to leak down to 4 psi. How long should pressure hold for? Can't wait to get my bike running. Has sit for 17 years. Carbs were a mess as well.
It's a reference test so that's probably good. Switch out to a vacuum pump and try that direction. If they seal under vacuum 100%, which is what I'd expect, dun worry bout it as they say in Jersey. Cheers.
Fantastic work..how can someone contact you for work?
motorestofl@gmail.com. Thanks.
How come the Valkarie 1500 doesn't have a pump where my carb. VFR750F does?
Tank petcock is high enough to provide gravity feed.
WOW !!! Boy you are GOOD.
Is it (Valkyrie) now OLD technology? How would you describe it in your own words?
How does it compare with the Goldwing technology???
THANK YOU VERY MUCH sir.

I can't speak on the Wings, I've never worked on one. As for the first part of your question, it's complicated. Not the answer, but the setup. I have a hard time describing this sometimes, but any multi-cylinder engine which is carbureted must be treated with the concept that the carbs are Precision Fuel Metering Devices. Consider the challenges of the engineers on later units. The have to walk a very fine line between performance, balance, fuel economy and EPA standards for USA bikes. Thus, they operate on a thin line of air -- fuel -- ignition -- timing -- valves, etc. Carbs really need to be 100% spot-on in order to be at the place the imagineers designed the ENTIRE system. Valve clearance, compression, ignition voltage, it all plays a role. Extricating everything else and assuming it's nominal, I treat carbs like I said, as precise fuel metering devices. As such, I deal with them very... precisely. Cheers.
