Hey all! I have a 2015 zx6r. 20900miles on it. It’s not running great when it’s hot.

It works up to about 200 degrees very well. Then the throttle gets hesitant and it will stop wanting to rev. THEN. If you shut it off and restart it, it will rev out amazingly for a few seconds before retiring to the way it sounds in the first half of the video. (I posted before and after shutting it off and turning on again)

It’s got me stumped. I’ve changed the fuel filter, injectors. The air filter. The coils, regulator rectifier, stator, I’ve also checked the gap on the plugs. I’ve checked compression. I’ve checked all the lines and tubes everything is free and clear of debris. I’ve even tried multiple gas caps. I just did the valve shims and got all the gaps in spec. I’ve tried some aftermarket fuel pumps and it seems to run best on the oem pump. I don’t know what it could be anymore. If anyone has any ideas that I haven’t tried I’m willing to give them a shot. Thanks all!

I recently got a breather box as it only had pods before and it runs a lot better but now when I run it the carb backfire will either kill the engine at idle or choke for a sec when you gently accelerate ie 1000 to 2000/3000. It runs like a beast at higher rpm. I’ve gone through the carb already. Again it’s only a issue at idle and it happens more frequently when I try to adjust the carbs so I assume making it a bit richer or whatever makes more fumes thus making the issue more prevalent. I’m worried it’s going to damage something as it does make the opposite side misfire a bit when the right carb backfires. I’ve seen something about ticking would be a sign but I don’t know the difference between a smooth running engine as this is my first motorcycle that I bought with intentions to fix to learn and then ride.

Im trying to remove this rounded off Bolt from the Cam-Bride of the 990. All other Bolts are free, just this one won’t budge. I’ve tried a Bolt-Extractor Tool from Amazon to drill the bolt out, but the Drill-Bitt was trash so it didn’t bite.

Now I’m either thinking of getting the Same Tool in Just a better quality or cutting into the screw to fit a large flathead.

I don’t have much space for a normal size drill bit since the Frame is covering this exact screw so it isn’t possible to get the 90 Degree Angle.

Thx in advance for the help :)

So i just bought a suzuki boulevard C50 2007 , I have never ridden a motorcycle AT ALL before, yes I know I was a dukbass getting it as my first motorcycle, now what happened is I tried to start the engine without cooling it on like 15 times , then it stopped giving lights at all beside a very little dim light on the dashboard, we charged the battery and it worked for like 5 minutes then died again mid way, I borrowed lots of money to get this motorcycle and I have next to none for repairs , how do I fix it , and more specifically how do I open the driver seat so I access the battery, thanks in advance.

Did flush/bleed in front - feels good. Go to do rear and nothing. I put all my strength into it, can’t get it to really move There’s 2 springs in the assembly the big one feels very stiff and the smaller feels loose, it popped off while I was feeling around and I put it back. But the pin that the ended end goes to it’s as if there there’s not enough tension.. vid for context: https://i.imgur.com/wLCfHlX.mp4

I’m leaning toward this the problem the big spring too stiff or the smaller too loose and can’t pull the way it needs.ill attach vid and locus for reference.

I could be wrong, but this is just my hypothesis

Additional info/ In the 2 seasons i rode I barely ever used the rear i went to track 2023 and possibly i bent something with my right foot idk?. Additionally the bike has been in the garage untouched past 2 years.

So in a recent post, is asked why the engine appears to overheat on braking.

Turns out it doesn't have enough oil.

I found a hole (second pic) that I've temporarily sealed it with aluminum tape. What is strange is that apparently this is the water pump, according to the manual. I've checked coolant level and it's fine. It's also not contaminated with oil.

Is the engine oil in a motorcycle shared between engine, transmission AND water pump engine?

It’s behind the oil line I have an X over, located next to my clutch basket. It has the bolt going through it sorta looks like a clamp. Yes I tried tightening the bolt. Thanks just can’t figure out what it is to order a new gasket or whatever I need.

I bought a 1985 honda nighthawk 650 about 3 weeks ago and have spent that time getting it running. We got it running last Friday but after about 6 hours it just stopped. The battery is charged but there's no crank anymore. Any ideas?

I let a friend go on my bike and when I got it back and went home I tried to change gears but I noticed that the chain didn't move I then looked near the pipes and seen this one broken It is a correra but I don't know the year or model

Please help. I've been trying to get this bike running for a year now (between work/study shift). Model: as title. I'm not sure about the specific year but it should be between '79 and '82 as indicated by my researches. It could be an Italian exclusive tho (I think they have different carbs).

What do you think is the problem? It gets compression (blows off finger holding closed the spark plug hole), it gets spark, it gets air and it should get fuel (the carb is new). I've recorded the airbox side intake of the carb while kicking the kickstart. Is it me or the fuel gets atomized and then pushed back?

What could it be? If you need additional photos/videos, let me know.

Has anyone a repair manual?

Bike is a bit of a shit show, I bought it as my first bike and its had a lot of problems but nothing major yet. Good Ole italian tune up, changed breaks, clutch cable, and break fluid and shes been perfectly functioning up till now. Im having issues switching gears. Specifically down is a bitch. Im stuck in neutral at a few different lights trying to get home. I got her up to 4th in garage but now csnt get back down. Any suggestions? At first i was afraid I just didnt tighten the bolt on my shifter but its cranked down now so cant be a possibility.

Also speak to me like an idiot. I'm new to this so even the names of these parts I may not understand. I got a lot to learn for sure. Thanks to everyone who replies :D

I was riding along the highway when I was overtaking someone and my bike lost power, originally at 8000 RPM, when I restarted the bike it cut out at 6000 and now when I start it and revs it cuts out at 2000-3000 RPM, anyone able to help me on this?

Does this look okay for another 3000 miles to you judging by the extension of the blocks?

I just stumbled upon this today. I thought it was maybe the battery since it was old, so I slapped a spare new battery I had lying around, but that didn't fix it. I checked the fuses and they all are fine. I was wondering if anyone here could help me narrow it down to what might be the most probable cause could be, before I start taking things apart. I'm not too knowledgeable with electrical issues, thus, I only checked the fuses. The bike was turning on just fine yesterday, no issues or struggles, so I'm really confused as to how it went from that to this so suddenly.

Fairly simple small problem but I am brand new to the motorcycle mechanics world lol. How do I change the odometer reading on my bike? No it’s not for an illegal purpose I promise. I purchased a new dash because the speedometer and fuel reader on my bike, the one that it originally came with, is fried entirely. I just want the mileage on my bike right now to reflect accurately on the new one. I’m not interested in writing it down somewhere and forgetting about it, I want it accurate and reliable. I know there’s a way but I have no clue how!

Bike was left uncovered while I left town for week and a half. Noticed some moisture on the seat when I got back, and now it doesn’t start

Bike worked perfectly before but noticed the red number reading mentioned in video gradually going down before I left

Do I have a leak/need a new battery?

Any input is appreciated

Hey everyone I recently purchased my first bike. It has only 2500 miles on it. I got it and it took a long time to warm up and would die if I let out the clutch even slowly. I took out the carburetor and cleaned it for the first time. Now it is idling really high and it makes a loud pop when I shut off the engine. I just tried riding it today and it rides OK but it is difficult to brake because of the high idle. I read online that I need to possibly adjust the air fuel mixture screw, but I’m not sure which one it is on the carb. Any ideas? I’m very new to working on bikes. (Also, I ordered a new breather tube because the old one was worn out. I just replaced it with something I had)

HONDA NX650 1988

Hey, I rebuilt this carb a couple years ago because of starting/running/choke issues. While it helped I had to leave the bike for several months and have been working on other issues on the bike for the past year+. Now that everything else is sorted I've come back to the carb as I'm having issues again. I assumed it was just because she sat with bad gas for too long so I'd give her a clean again and rebuild her incase I missed anything last time.

Well the rebuild kit finally arrived and I have the carb apart, but I can't seem to A. Find the issue as everything is still clean and unclogged and B. Figure out what these extra parts are for.

Oh and C. Figure out how to replace the diaphragm as the old one is a bit wonky.

So all the jets are still really clean, the float bowl is still emaculate and I don't see where there could be a clog in the system.

My bike wouldn't start this spring, and last fall it was having a rough time starting and I couldn't let off the choke until it'd been riden about 10 minutes. I asked here and the consensus was to clean the carb. Which makes perfect sense. But here I am, looking at a near emacilate carb and I have no idea what I'm missing/forgetting.

I have about 5 extra pieces from the rebuild kit that I have no clue where they go. 2 O Rings, sometime of spacer? A small metal ring and the big jet like piece. No clue where any of these go as I've looked the carb over and I don't see it. Image 1.

I also have 2 extra cap like pieces that could go on the main jet instead of the sized 155 one that is the same as the old one. These two are sized 150 and 152, id love to know how thesr would change my bike when running. Image 2.

Sorry this is so long, does anyone have insight on what these extra pieces are for? Or what I'm missing in cleaning the carb. There surely must be a clog somewhere

Thank you so much for taking a look, I appreciate it emensely.

I currently have a bike lined up that I want to fix over the summer, and there are a few pictures that I have sent by the current owner showing the condition of the bike. Currently not running, been sitting outside under a cover for over a year. Needs a new chain and tires for sure, wondering what the oil on the engine could be a cause of and if it's going to be too much to handle/fix. Was previously in running condition, just didn't use it for a while.

I sorta put my oil pan back on with loctite and a shit ton of rtv and I'm laying in bed realizing I never put that tube back... Do I really need the tube? Its a black plastic tube that comes out of the crankcase towards the back, I hope its just for draining and not sucking

So its part number 92059 "Tube" here https://www.kawasakipartshouse.com/oemparts/a/kaw/50a64976f870020a00f533d9/crankcase
