They need to be changed

While changing the oil on
I've got to beleive at minimum you're looking at a top-end. That would include valves/piston/ring and associated machine work. The grey/white oil indicates coolant coming into the cylinder head and mixing with your oil. Not a good sign. Hate to be the bearer of bad news but it looks like a pretty involved repair.

Is there a way to
check the clearance between the rear tire and inner rear fender, maybe stuff a shorter shock in there. also look into a different seat, maybe one with a thinner thickness
The pin that the hydraulic
The biggest problem with the clutch system that Honda uses on it's bigger bikes is the replaceable bushing in the lever wears out quickly. If it is worn at all , it can cause binding and problems with clutching. The rod is just a connector between the lever bushing and the piston/plunger. The plunger is spring loaded and should return to the full out position after being depressed/pushed in fully. When the assembly is together and you apply pressure to the master cylinder piston by pulling the lever it should push the piston and depress the internal spring, then the piston should come back out by itself. If you push the piston all the way in and it stays there , you will need to buy a clutch master cylinder kit and rebuild the master. All the internal pieces for the clutch master come in the kit. To disassemble you gently pull the rubber cover out and remove the circlip with a snap ring pliers . Then the piston and spring should slide right out. Note the position of all the pieces to make reassembling the new pieces easier.
If your clutch will not engage when the piston is pushed in fully, you probably have air in the slave , the line , or the master cylinder. Remove the top master cylinder cover and top up the system with DOT 3/4 brake fluid and bleed the slave cylinder. Warning: be careful not to spill DOT Brake fluid on your paint or plastic. You may want to lay a piece of plastic and an old towel over the bike to catch any drips. Place a tube on the bleeder screw (slave cylinder) and loosen the bleeder screw. now pump the lever to push the air out of the system. Hint: if you do not have pressure in the master, loosen the brake hose banjo bolt enough to burp the air out of the master. Retighten the banjo bolt and bleed the rest of the system.
Bleeding the system should restore clutch performance. If you notice fluid leaking from the master or slave cylinder , replace the o-rings in the slave cylinder piston and rebuild the master cylinder. A master cylinder kit and slave cylinder o-rings are available at your local Honda dealer.
Oil is comong out of
make sure u hav correct grade lubricant-the oil maybe to thick or double check level to make sure its not too high
Hello, I actually have a
Disassemble the carburetor and clean it. The jets are partially gummed up from old gas that has evaporated leaving a varnish build up. If you can, soak the entire carb and parts in denatured alcohol for about an hour. Then clean with spray carb cleaner. Spray into every hole and jet in the carb. On re-assembly, lightly seat the throttle and air screws then open each of them one and one half turns. This is the factory setting. Please rate my answer. Thanks.
My 2007 crf 450 will not start
Im sorry but theres no way that once a sparkplug is removed that there is compression granted that there is air being sucked in and pushed out of the spark plug hole but no , no compression....
Installing cam chain on 09 CRF 450
check that the new cam chain is roughly the same length as the old one, ensure that it is properly installed on the bottom (crank) sprocket, make sure that your tensioner is backed off fully, even after all of this you will still find that the chain seems too short, tip the cam to the left side of the engine & your chain should slip on..double check your cam timing with cam cap snugged down & tensioner released.
Honda 500 TRX fa6 has PS on the dash….what does it mean ?
The Power Steering has failed. There has been a factory recall for a suddenly failing electrical steering shaft, that could cause the rider to loose control. This does not have to be your problem but anyhow either the electronics or the pump failed. Error codes or messages usually have to be erased by a simple reset procedure or disconnecting a plug, after repairs are done.

What to torque the head on my 99 CBR 929 Honda in
For a 1999 Honda CBR929RR, the cylinder head bolt torque specifications are essential to ensure proper engine assembly and function. When tightening the cylinder head bolts, it's crucial to follow the manufacturer's recommended torque settings to prevent damage to the engine components.
For the CBR929RR, the cylinder head bolt torque specifications are typically as follows:
1. **Initial Torque:** 29 Nm (2.9 kgf-m, 22 ft-lbs)
2. **Final Torque:** 64 Nm (6.4 kgf-m, 47 ft-lbs)
It's essential to tighten the cylinder head bolts in the specified sequence and in multiple stages, gradually increasing the torque until reaching the final specified torque. The exact tightening sequence can usually be found in the service manual specific to your motorcycle model.
When torquing the head bolts, ensure you're using a reliable torque wrench calibrated in the appropriate units (Nm or ft-lbs). Always follow the tightening sequence precisely to ensure even pressure distribution across the cylinder head gasket.
Additionally, it's advisable to use new cylinder head bolts if the old ones have been previously tightened or stretched beyond their yield point. This helps maintain proper clamping force and ensures the integrity of the engine assembly.
As always, referring to the service manual or consulting a professional mechanic experienced with motorcycle engine assembly can provide additional guidance and ensure the correct torque settings are applied during the cylinder head installation process.

2006 Honda Shadow Arrow 750 VT missing on the rear cylinder fire
. One possibility is that the spark plug or plug wire is faulty 1. Another possibility is that the carburetor needs cleaning and adjustment It could also be due to a valve adjustment issue or a bent rod.
I would recommend taking your motorcycle to a professional mechanic who can diagnose and fix the issue. If you prefer to troubleshoot it yourself, you can start by checking the spark plug and plug wire for any damage or wear and cleaning the carburetor. However, please note that working on a motorcycle engine can be dangerous and requires specialized knowledge and tools. Please take all necessary safety precautions and follow the manufacturer's instructions when working on your motorcycle.

2007 honda shadow vt750 dies sputters on acceleration
The problem might be with the air filter, and if not there are a few other things that could be causing your Shadow engine to bog down on acceleration. This includes a dirty carburetor, carb adjustment issues, or other internal problems like damaged vacuum lines or a cracked manifold
