Sourcing an original bore kit for an old model Honda Activa will be more difficult than an aftermarket one, but still possible. Your primary target should be authorized Honda dealerships, particularly those with a long history or a good reputation for parts service. They can check their inventory and potentially their network for old stock or NOS (New Old Stock) parts. Online retailers specializing in genuine Honda parts are also worth investigating. You'll need your Activa's exact model and year to ensure you're getting the precise kit. It's crucial to verify the authenticity of any "original" part you find online, as counterfeits exist. Be prepared for the possibility that the original bore kit may be discontinued; in that case, a high-quality aftermarket option, designed specifically for your model, from a reputable manufacturer would be a suitable alternative, and you may need to consult with a trusted mechanic specializing in older scooters to determine the best course of action.

Finding a standard brake spring for an old model Honda Activa should be relatively straightforward. Many authorized Honda dealerships carry common parts, even for older models. They can check availability and order it if needed. Online retailers specializing in scooter parts are a good alternative and often have a wide selection. Search using "Honda Activa," your model year, and "brake spring." Local auto parts stores, especially those focused on two-wheelers, may also stock the correct spring or can likely find one through their suppliers. Because brake springs are a common wear item, there's a good chance that a standard aftermarket replacement from a reputable brand will also be readily available and fit your Activa perfectly. A workshop that services two wheelers can help you get this.

Using Castrol engine oil in an old model Honda Activa is perfectly fine, as long as you choose the correct type and viscosity grade recommended for your scooter. Castrol is a reputable brand and offers a range of oils suitable for scooters. You'll want to consult your Activa's owner's manual to find the manufacturer's recommended oil specifications, typically a 10W-30 or 10W-40 JASO MB oil for scooters. Once you know the correct specifications, you can easily find a suitable Castrol engine oil at most automotive parts stores, online retailers, or even larger supermarkets. Castrol's popular options often include their "Power1" or "Activ" lines, with formulations designed for scooters that meet the JASO MB specification. Just ensure the oil you select matches the recommended grade and specifications for your specific Activa model year to ensure optimal performance and engine protection. Most likely it would be Castrol Activ 10w30.

While Bosch is a well-known and respected brand in the automotive industry, they are primarily known for their spark plugs, filters, and other automotive components, not for engine oil. It's highly unlikely you'll find engine oil branded as "Bosch" for your old model Honda Activa, or for any vehicle for that matter. You'll need to use a reputable engine oil brand that produces lubricants meeting the specifications recommended in your Activa's owner's manual. This typically means a 10W-30 or 10W-40 JASO MB oil designed for scooters. Popular and readily available brands include Castrol, Mobil, Shell, Valvoline, and Motul, among others. Stick to these established oil manufacturers to ensure you're using a product that provides proper protection and performance for your scooter's engine. They would be easily available.

Using Honda genuine engine oil in your old model Honda Activa is a great choice, as it's specifically formulated for Honda engines. You should be able to find it at authorized Honda dealerships and service centers. They will have the correct oil that meets the specifications recommended in your Activa's owner's manual. The specific type of Honda oil you need will likely be a 10W-30 or 10W-40 JASO MB designated for scooters, and it will typically be branded as "Honda 4-Stroke Motorcycle Oil" or something similar. While Honda genuine oil might be slightly more expensive than some aftermarket options, it provides assurance of quality and compatibility with your scooter's engine. You can also likely find Honda engine oil through online retailers specializing in genuine Honda parts, although availability might vary depending on your region.

The clutch cover on older Honda Activa models is secured using specific bolts designed to ensure a tight seal and maintain the integrity of the transmission system.
