Is there an unusual sound or "feel" to the bike?

This is my honda cb400 nc39 2004, I got it q while back, the bike is in rough shape and haven't been maintained well. I'm working on it on my weekends but I think there is something wrong with the carbs.

I'm no mechanic, but I think the carbs aren't synced based on the sound

I want to make sure so I'm asking the CB experts here! Thank you in advance

1982 Honda CB650 Help Needed!

So I’ve got a 1982 Honda CB650 that I’ve been working on as a project but I’ve run into a problem now. I put all new jets in the carbs and have fully soaked all of the carbs in an ultrasonic bath. When I run the bike I can run perfectly at idle when choke is MAYBE 1/4 of the way on, or if i put tension on the throttle when choke is off (Idling around 1200-1500). The minute i release the tension on the throttle with no choke, she dies. Vacuum’s are showing “late valve timing or leak at intake manifold”. What would be the best ways to go about checking what could be wrong? Stretched throttle cable? Cracked boots? Need some advice as I’m not familiar with these at ALL and should have done more research but we all start somewhere…

Honda just doubled the price of the H'ness CB350 Front Fender? ₹3,235 ➜ ₹6,416! Is this normal or are we getting ripped off? 🤯 #CB350 #HondaBigWing

was checking genuine accessories for my Honda CB350 RS on the Honda app today and noticed something that shocked me. Called the service centre they also said even they don't know why honda has increased this much price .

The Front Fender Kit (Part No. 08R70-K0Z-D30ZA), which was previously listed at around ₹3,235, is now showing an MRP of ₹6,416 (inclusive of taxes).

That's almost a 100% price increase.

With the monsoon here, many CB350 owners are looking to install the front fender to reduce mud and water splash. Seeing the price jump like this feels hard to justify.

If this is an actual price hike, it's disappointing considering this is a genuine accessory that many owners buy. Suggest me what to do? I don't want the after market mudguard they tend to break the original mudguard of cb350rs

Carb Help

Hey guys, I was trying to adjust my Honda nighthawk CB450SC by turning the only screw I found on it, but other than changing the idle (since it's been idling and running rich), gasoline started coming out of the overflow of my Carb. Does anybody have any idea why this happened?

New bandit 600 front end almost all here

Going on my 750F Need the parts which will be replaced now. Bearings, seals, pads, tire, etc. also going to have to modify the top clamp to hold the speedo/tach and headlight and all that. Going to look absolutely sick with a 17" front rim instead of the 19" comstar

Parts are off the Suzuki bandit 600 first gen, two pot nissin calipers, 41mm showa adjustable forks. Won't be using the master cylinder in the picture as I have a really nice one already on the bike. Not sure how the bearings and stem are going to work with the 750 neck but I will find out.

Burnishing bolt heads

I re-painted my wheels, and before reassembly I used a drill and some scotchbrite to burnish all the hardware to give them a satin finish.

Finally got our first CB!

The vintage CBs have always caught my eye. Decided to take some time away from work and get my hands dirty. Just did a carb rebuild and got her running pretty decently. Much more to come. Perfect bike to teach the lady how to ride! This bike is a 1973 frame with a '71 (or 72?) 350E engine. It was running rough and leaking when I got it. Felt great to get it to where it's at already.

Is Honda CB 350 most underrated bike of 350cc segment ????

81 cm400 only runs on left cylinder. Right cylinder fires when I spray starting fluid. Carb seems to be clean and air shutoff valve diagram is good. Any ideas?

Honda Nighthawk smells like gas

Hey guys, I just recently bought a 1984 450cc honda nighthawk off of facebook. Since then, I’ve been trying to store it in my garage but it releases a strong gasoline smell. So far I suspect that it may be the petcock as it was dripping gas from it when I turned it. However I don’t think it is possible for that to be the cause of the strong gasoline smell. Im currently absolutely lost on tackling this and any advice would be awesome. Thank you! (I think the nighthawk is part CB)

New to working on bikes, won’t go past 5k rpm in gear unless I lean to the right which will make it surge with the normal power, what is the issue?

Also idk why the neutral light shut off in the video, it went back to normal soon after

Engine concerns

1974 cb200. The bike ran before the timing chain tensioner started to fail. I got a clymers manual and attemped to do the repair myself, while I was in there I also replaced the clutch. Now it does this, note that pulling the clutch also doesn't affect the issues with the binding. I have the bike stripped down so the starter and harness isn't on it, I would also be afraid of using the starter with concerns that it would do more damage. I haven't turned the motor over yet with the crankshaft nut. The binding/ clunking sounds like its coming from the transmission case somewhere. I don't think its the engine compression because plugs were out. Could it be possible that the clutch plates are misaligned or the fork is incorrect, perhaps misassembled the kickstart assembly? Also any ideas what the deal with not being able to get into first. I'm kinda lost at this point and need some wise advice from some vintage Honda gurus.

1982 nighthawk cb650sc

Getting close to giving up on this bike. Finally fixed the leak in the carb and now the throttle is sticking. Thought the cables were just too tight at first till I pulled the rack out AGAIN and noticed the two inner butterflies not closing all the way. Also the spring I’m pushing down on isn’t smooth it feels like it’s grinding. Any advice would be great
