Your Aviator has an ignition coil, rather than a magneto, to generate the spark. That means that it relies on the battery to have enough charge to generate the spark, so likely the ignition is only producing sparks once you've cranked the engine over enough to put a little charge into the battery. Engines with magnetos that generate the spark directly from ...

While this is an educated guess, I'd put money on the fact this is oil coming from the oil filler cap. It appears the cap isn't sealing completely, or possibly the cap isn't screwed on tight enough. If tightening it a little more doesn't work, you'll need to replace the seal on this to get it to stop. The seal itself may be an o-ring type, or it could be ...

I would not want to increase load to your dynamo. I'm skeptical that you actually have that type of charging system but can't back my claim. IF it is a dynamo then I would do something in order to add your accessory lighting load. - Replace your current headlight with an LED version, it will consume less electricity and give you room to add the accessory ...

I assume you mean that when the engine is cold, it requires the choke, but then if you stop and try to restart, then you have to turn off the choke. This is by design. The choke is a tool to allow a cold engine to run by enriching the fuel/air mix through restricting (or choking) the air supply - once the engine is warmed up, this is not needed any more. ...

It looks like that piece is before the carb on that bike. It acts as a resonator, helping to damping out noises from the intake without adding restriction. Plenty of cars have the same thing in the intake. Some cars have a similar device in the exhaust after the muffler. It is often just a short piece of pipe welded into the main exhaust pipe.

I'll start with the bad news - if it's the CD100 model without electric start then it's a no-go unless you replace the engine (I'm inferring this from your statement "customize my old bike with a self start"). You won't be able to retro fit a starter to it as the cases and internals will not be configured for one. However, if the engine does have electric ...

Having your bike in neutral will cause no additional wear on the clutch. When you have your bike in neutral and you have re-engaged the clutch (released the handle), the clutch is fully engaged without any torque being applied to it like it would normally see when in gear. The only way a clutch sees wear is when it is slipping. This is when you pull the ...

There are a few things to consider when changing lighting: 1) Draw on electrical system The draw should ideally be equal to the existing bulb. If it's greater, then you need to make sure the wiring is of a sufficient gauge to handle the load. Drawing more than the existing wires can handle is dangerous. Best case scenario you'll blow a fuse and your new ...

If it really is only audible when the engine is at its compression stroke or the subsequent power stroke, in theory these are the only possible options: -worn piston rings -leaking head gasket -leaking valves -loose spark plug(s) If you turn over the engine slowly, like when pushing down the kickstarter slowly, it's not uncommon to hear air leaking past ...

If replacing the battery worked then it is the very likely culprit. Batteries die when left for a long time without occasional charging. If the bike starts well after being on charge overnight then the battery is a major likelihood. Valve problems arise in mechanics heads when they need to make some money from you. This type of problem can be best fixed ...

First, replace the battery if you know it's bad. If the engine won't start when "cold," the choke on the carburetor is possibly the problem. Any gasoline engine requires a small amount of fuel enrichment upon starting when the engine is "cold." This is accomplished by the choke mechanism, which partially closes off airflow to the carb with a flap. Reduced ...

If you mean it isn't starting when it's in gear with the clutch disengaged, and it used to start under those conditions, check to see if there's a pin switch on the clutch lever housing that's gotten stuck. If so, then the starter won't be able to tell you've got the clutch lever pulled and will refuse to start. You should be able to fix it by spraying some ...

One reason can be marketing, to appeal potential buyers with extended engine oil change intervals.

Stick to Honda corp. For their standards, they know their engines well. Besides Hero and Honda had a combined venture until 2015.

Check this out.. It's the same question on another forum. Based on the markings on other motors I have, that should be closed/on and up would be open/off. Post a picture of the switch in the horizontal position too for more accurate help.

Turn the choke ON to start a cold engine. I cannot see the image, so I do not know if this is vertical or horizontal. If you can look at the choke blade, the choke is ON when it is blocking the path. Once it is running, set it to PARTIAL (diagonal) until the engine is warm. Once the engine has been running a few minutes, set it to OFF. Choke helps the ...
