Make sure your clutch is depressing the plates fully ,your cable might need changing or adjusting .

the stalling when going in to gear sounds a bit like the side stand switch has been damaged and it thinks the side-stand is down.But if it fell on the right side this is unlikely.Also this wouldn't explain the grinding when trying to select 2nd.
Possibly the clutch isn't disengaging properly - have you tried putting it in to gear (motor not running) and pushing it with the clutch pulled in? If it is in gear and you can push it forwards OK with the clutch pulled in then assume the clutch is disengaging OK.
This will be a starting point.
turn the engine off then roll it forward in neutral, then engage 1st gear , it will feel bit clumsy but it will then roll then again bring it some more then back into neutral, roll it back to original point (I'm start the bike, then check out. ----- also the other possibility can be The clutch lever wasn't impacted in the fall at all? It sounds like a engage/disengage problem like the travel nut was stripped on the clutch adjustment. That seems unlikely though because it would take a hell of a bang to do that but I would check the entire clutch cable from bars to bell housing. ---- This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

With a reputed top speed of 186 MPH on newer models, this is notout of line. Especiallyconsideringthat later models had horsepower improvements. I think this is well within limits without mods.

If you are talking about the stator, you need to remove the left engine side cover, remove the bolt that is holding the fly wheel to the crankshaft, then use a flywheel puller to get the flywheel off the crankshaft, then remove the 3 screws holding the stator to the cases. Unplug the electrical connection for the stator and reverse the procedure for reassembly. Use a new gasket, and be sure to apply Yamabond 4 to the case cover across the rubber plug for the wires and extend the yamabond down the cover gasket surface about 1" past the rubber on each side.
Use some lock tite when putting the screws back in to the new stator. You do not want them coming loose on you!
Make sure you get the bolt holding the flywheel tight when going back together.
That should fix you up!

if you have already replaced the battery, then the charging system would be the suspect. This is a complex system, so either get the manual, take it to a shop, or get the new battery.

Just a guess.

This sounds more like an electrical break from one of the engine sensors.
Take off the covers and check wiring routes, and for any cables that may have been damaged - or connectors that look corroded or blue.
It may be worth leaving ignition on and moving the wiring loom to see if you get any life while doung this to help find the fault.

After this, try locating the engine sensors themselves, as there is a missing signal from one of them.

Hope this helps you fix it.

Thank you for using Fixya.

error = cylinder ID

means you have the spark wires on wrong or harness wires

2002 Yamaha... | Answered on Aug 16, 2009

i think the engine oil is the problem.
because i think at above 80 degrees it is loosing its viscosity due to which the piston is slipping inside the cylinder.
change its engine oil .

Look for corrosion around the engine starter/ignition fuse, and also on the battery terminals and ground connections.The starter draws a lot more current then horn or gauges, so a weak ground connection will not affect them as much. If you find any corrosion, clean it off with a wire brush, then fine sandpaper, the use dielectric grease on the connections to stop new rust forming.

have you checked the stater/rectifier

2002 Yamaha... | Answered on Jul 01, 2009

From the sounds of your riding style (wheelies, etc.) you have burnt out the clutch.
No matter how much fun you think it is, Yamaha never designed them to be a toy to do wheelies. It is a sportsbike designed to go round corners fast.
The only silver lining is, hopefully the cost of replacing the clutch will stop you riding like a fool in future.

Do you have carbs or fuel injection? either way it sounds like something is clogged up.
Cleaning would probably help.

2002 Yamaha... | Answered on Jun 15, 2009

I've never worked on your type of bike but the way it's done on Harleys is to unplug the wires coming from the stator that plug into the regulator. Then start the bike and check the voltage coming from the stator by using a Volt Meter (AC VOLTS) on the plug at the end of the wires coming from the stator.

*You have to be Sure the voltmeter is set to AC Volts when checking the stator.*

We look for 30 to 40 volts AC if the stator is good. Of course your bike will be a little different but you might be able to do the same.

Hey pal, i got a feeling it's nothing like you think it is...the tank shouldn't lift without removing the bolt or bolts that hold it down...also many bikes have wires that run down the frame under the tank and here i where i think the problem lies....remove your tank completely, fuel lines, fuel guage wires etc... and set tank aside....now carefully inspect where your tank has been vibrating and rubbing on the wires, coils etc that are located there....take your time here as you will undoubtedly find a wire or connection that the tank has been rubbing on and now causing a short circuit......mend,repair, and insulate anything that has been damaged..then carefully reassemble and enjoy your ride....Good Luck to you friend.....Tim
