the same thing happened to me its probably your valve clearance and need to be shimmed or if they worn really bad they need to be replaced..regarding roll starting your bike it damages your bike further and your engine could seize.
Keep the revs below red line - change the oil according to the instructions you have in your owner manual OR MORE OFTEN. Clean the air filter and keep the chain lubed. Keep proper pressure in the tires.
Yes. Your bike takes two different oils. You need to get in touch with a Honda motorcycle dealership. They will be able to provide you with the oil and information you need. Honda has its own special brand of oil for each application and filters. Good Luck.
if it starts and sounds bad its probably is.
If it doesent start the person who told you may be correct.
you may find metal shavings in the oil and filter, or pull the clutch cover off and look for more shavings.
They commonly destroy the big end bearings, I have repaired one before, its a major rebuild and may need a new crankshaft. Try to find another motor at a bike breakers\wreckers
There is a proper way to start an engine. Most bikes have four controls to assist in starting.
The choke, used when the engine is cold. Pull the red knob for choke.
The " Hot Start " Lever, used when the engine is hot. Pull the lever to lean the fuel mix when the engine has been running.
The de-compression lever, always used.
The throttle, used to prime the cylinder.
Don't kick, instead, push the kick lever downward. You will feel the back pressure as the piston is going upward on the compression stroke to the point the pressure is great enough that the kick lever "locks up". You are very close to TDC. NOW, pull in the de-compression lever. Push the kick lever a little bit more to get the piston past TDC. Now release the de-compression lever. Give the throttle a 1/4 turn then let it snap closed. A diaphragm in the carb gives a shot of gas when this is done. DO NOT do this multiple times because you will flood the engine. Leave the throttle closed when kicking. A flooded engine will often backfire. Now give a strong kick through the full sweep of the kick start lever. Quickly get your foot off the kick lever at the end of the kick to avoid any chance of "kickback" from the kick lever. This happens in the case of a misfire, aka > backfire. It can be very painful, and can even break a leg. I am serious about that. Repeat the process (but without the throttle priming), until the bike starts. Go ahead and give it another primer shot after the 5th kick attempt. A good battery, a clean spark plug, a clean carb and clean air filter will also aid in starting.
When an engine seizes you really have done great harm to it. My advice is to pull the motor and split the cases to inspect crank, and other parts. Invest in new cylinder & piston (w\rings) at the very least. It is more likely that you are going to need some new bearings and machine work. Sorry for the bad news...but that is exactly what seizing an engine is, bad news.
When you say kick strat wont go down, do you mean engine is "stuck" If this is the case the engine is "seized" try turning engine over with a spanner on the drive sprocket. If no movement at all engine is seized.I assume that the radiator is full of coolant??
