The Honda NSR 125 may be losing oil due to a few possible reasons. One common cause could be a leak in the oil seal or gasket, which can result in oil leaking out of the engine. Another possibility is that the piston rings or valve seals are worn out, causing oil to be burned along with the fuel. It's also important to check for any cracks or damage to the engine casing or oil lines, as these can also lead to oil leaks. Regular maintenance and inspection of the bike's engine components can help identify and address the source of the oil loss. **

The oil drain plug may not tighten anymore due to several reasons. It could be because the threads on the drain plug or oil pan are stripped, preventing a secure fit. Additionally, the drain plug may have been cross-threaded during the last oil change, causing damage to the threads. It is also possible that the drain plug gasket is worn out or missing, leading to a poor seal and preventing the plug from tightening properly. **

Yes, the drain can potentially become clogged by a sugar-oil scrub. The combination of sugar and oil can solidify and create a sticky residue that may adhere to the walls of the drain pipes, leading to blockages over time. It is important to be cautious when rinsing off sugar-oil scrubs in sinks or showers to prevent clogging issues. Regularly using a drain strainer or flushing the drain with hot water can help prevent clogs from forming. **

It is not recommended to pour coconut oil down the drain as it can solidify and clog the pipes. Over time, the oil can build up and cause blockages, leading to potential plumbing issues.

It is typically either a 14mm or 17mm hex head, but it's important to consult the owner's manual or a mechanic to confirm the correct size for your specific vehicle. Using the wrong size wrench can strip the plug and cause damage, so it's important to ensure you have the correct size before attempting to remove the oil drain plug. **

One should never dispose of oil in the drain as it can cause clogs and damage to the plumbing system. Instead, one should let the oil cool and then pour it into a sealable container and throw it in the trash.
