Good luck and thank you for asking FixYa..

Didn't say much about what it does or doesn't do as trying to start. The batrtey all the way up? if not it can refuse to start even if cranking 2002 and newer may push start but only if the battery is near good 04 and newer are fuel injection and a low or bad battery is a no start on it's own the modern glass mat batteries don't take a jump very well as they resist being pushed back to full voltage even with a car battery. Cranks good with a good battery. Got gas and the valve on? Carb bikes may have to have the fuel pet on prime to start a (dry) motor. The fuel injection bikes have to have the good battery or the fuel pump can be below theasehold and the relay won't turn the pump on. All the lights and others horn ect working? No crank can be clutch switch kickstand switch if the locic box is burnt out or low voltage, Neutral light working? if not the kickstand has to be up for crank. Burn the strarter out cranking with low battery? Strong click when pushing the start button says the safty switches are working. and the starter could be bad or lost it's ground. Will the engin turn? put the bike in higher gear and push it with the clutch out to see if it will turn good compression may be hard to push but not impossible as the starter and you have about the same power, remember they used to have kickers and this one had one it'd work to start it. Carb bikes have drain bolts on the float bowels and little hses hooked to them if their still there open the screws to see that theres gas or something else in the corbs. and will more come from the tank? Spark the plug wires snap to the plugs and are hard to remove if good put a plug ( any good plug will do) and crank the engine to see the spark at the wire. if not kill switches crash swiches may have to be reset then the key on and off too. lfter that its lookto see whats missing as compression spark and fuel are all it needs to run. If it jumped time the compression won't be good or out rajous. Exhaust stopped up? I've seena mouse store corn in the exhaust and forget wher he packed it. seen a R6 completly full! no start air cleaner housings get filled the same way. these don't apply if the bike had been running recently. Bad or poor battery most likly cause of no start then cable connections

don't drain furl man. from what i've read so far it sounds like you got a little mess. few things you should do to get you going in the right direction... clean the bottom of your motor and find where oil might be coming from. 2nd, i'm assuming your battery is dead again because you tried to continuously start the bike with no results right? if im wrong then you've got a charging system issue which isn't easy to diagnose over interweb. another clue to the problem would be to see what the ticking is, the main relay? could be bad also.

Check the choke to make sure its operating correctly.

Hi Dave,
Looking from front of bike, sump drain plug is on the Right.It will be necessary to remove the r/s Fairing, Once the fairing has been removed,the drain plug can be seen at the lower end of engine.
Hope this helps.

If it's been sitting for 2 years, the carbs are clogged and battery is toast most probably....sometimes these good friend "deals" are not really so good...A thousand things could be wrong w/it and if your not mechanical you can find a private mechanic that will charge much less than a shop, just make sure he is reputable.....you can download a service manual for free at carlsalter.com if you want to get your hands dirty....Good Luck to you friend.....Tim

This is a highly ill - eagle act to do. In the old days we would put an electric drill on the drive cable, but now they make them tamper proof so they only go one way. The bezels are crimped on so you can't get inside them. I expect modern one may be electronic. How will your insurance company know what mileage you have done? I have never known an insurance cancel or fine due to mileage. You should have just disconnected it when you got close to the limit. Buy a used one and use them for 6 months in turns.

Make sure the fuel is getting to the valve and passing through it. Possible blockage in fuel line or in the tank.

It isn't called a Magneto, that was for really old bikes. It is a 'stator'.

First make sure that the new battery has been fully charged and is not defective. Next make sure that the proper voltage is reaching the started. You may have a bad post connection or loose connection at the starter. Try jumping you battery with another known good battery.

What Exactly does the bike do when it 'loses power'? This will give clues as to where the issue could be. When was the last time the bike was given a major service? Sometimes it can be as simple as a dirty fuel/air filter or an old/worn or dirty spark plug.

Are you wanting the size of the hex bolt head or the thread size and bolt length? Most oil pan plug bolts are either 17mm (5/8th socket) or 19mm (3/4" socket) bolt heads.

1. Fuel System Issues:
   • Check the fuel system for clogs, such as a dirty fuel filter or carburetor jets.
   • Ensure that the fuel tank and fuel lines are clean and free from debris.
   • Consider adding a fuel system cleaner to help clean out any deposits.
2. Ignition System Problems:
   • Inspect the spark plugs for fouling, wear, or improper gap.
   • Check the ignition timing to make sure it's set correctly.
   • Inspect the ignition coils and wiring for any loose connections or damage.
3. Air Intake and Exhaust Issues:
   • Examine the air filter for clogs or dirt that may restrict airflow.
   • Inspect the exhaust system for any leaks or blockages.
4. Vacuum Leaks:
   • Check for vacuum leaks in hoses, gaskets, or intake boots. A vacuum leak can cause an improper air-fuel mixture, leading to backfiring.

Chain broken. Tetth stripped on final drive. Etc etc. Take a look.
