replace starter solinoide !

why do homeless people don't get love and more money like we do.

get a dealer to do a valve leakage test to check the valves ok and to check the valve seals and compression test , sounds like your gettingback pressure through breather pipe and may need overhaul of engine ! P...

you need to remove the starter motor and replace the brushes and give a good clean out ! P...

wot do you mean it wont throttle , does it tickover but wont rev up you mean ? better info please ! P...

ok first check the negative terminal and ensure you have a proper ground. then you have to check the stator and regulator / rectifier, you can check the stator which rarely goes bad by using a multi-meter on AC it should give you a voltage reading when cranking the bike over be careful you could get shocked now with the bike off check the regulator / rectifier by using the diode setting you can check to see if your rectifier is working use the leads and check the wires that come from the stator and the other lead on the wire that goes to the starter you will get voltage one way and the other you shouldn't so you will have to switch the leads. so if you get voltage both ways the regulator is bad or if you don't get voltage at al it is bad.

Well...A fuel line may have split due to heat, Or a bad clamp on the filter or fuel valve, If it carbureted, then You may have a leaky fuel bowl gasket/ Stuck float/bad float/or a out of adjustment float.

aluminum or pot metal both will break if u force it unless you heat it with a small plumbers torch untill it moves easily

have you checked the igniter unit at the side of the the pillion seat and when did you last change the plugs

This is an extreme long shot, but do you have to "reset" the fault code? It may stay "locked up" after a fault, even though you have replaced the faulty component. Does the manual say anything along these lines?Or its just the CDI unit that's not working

1. make sure that the coolant is at the correct level.2. when it is running hot the cooling fan(s) should be running or it will get hot. If the fan(s) are not running check the fan switch, fan relay, and the fan for correct operation. The fan switch should have continuity once engine is about 195+. The relay should click taken out of the system and 12 volts is applied to the smaller two relay terminal; at the same time it clicks, the larger two relay terminals should have continuity. Unplug the fan at the connector and apply 12 volts dc to fan side of the connector and the fan should turn on.

its usually connected with a spring to u'r brake pedal or built into the master and works of the pressure of you pressing the pedal. look at number 10. http://www.yamahapartshouse.com/oemparts/a/yam/500444e2f8700209bc78f4ee/electrical-2

take seat off lift tank and disconnect all hoses and wires and the fuel pumps built in to tank. take the bolts off the ring and and washer and the fuel pump drops out.

A non working speedo will not have anything to do with your ability to tune the air/fuel ratio.

The colour code should be on the frame, usually under the seat.To find a supplier, just use a search engine and find a distributor locally. Or order it online.

1998 to 2002 have problem with plug to voltage regulator/rectifier which is under seat. connectors in plug overheat and bike stops charging the battery. you will see if connectors have been hot and will need to be replaced if they have.
once replaced check bike charging with multimeter at battery,should make 13.5 - to 14.5 volts just above idle. if not will need to test stator and regulator.

FYI This has just happened to me.Bike has been stood for a few weeks and i started it. Noticed the temp was unusually high (105-110) so switched off, checked coolant and it was dry.I topped up and noticed the coolant leaking from what appears to be a hole in the engine sump casing.Im a fairly fast worker and i managed to remove the entire exhaust system down to the header pipes and drop the oil and remove the sump casing in around an hour. It might take longer if you don't do much mechanical stuff. (I'm just a hobbyist btw not a mechanic).It turns out that the hole in the sump casing is actually linked to a coolant overflow pipe internally. So don't worry coolant is NOT mixing with your oil (and therefore oil is NOT mixing with your coolant!)So obviously there is something more to this than meets the eye.It turns out that on all Pre2006 R1's the Water Pump is internal and if it leaks, You guessed it, It used this overflow pipe to stop the coolant mixing with your oil.This is where my mechanical knowledge ends and i will be taking my bike to a real mechanic to swap out the water pump for me.The good thing is, if you already remove your exhaust system and drop all your oil etc this will save around 1-2hours of labour at the garage!When they've fixed, get them to replace the oil and filter and leave them your exhaust if you like to fit and they can run it up and test it before returning to you working:)Samantha x

hi did you find out what was wrong with it? i am having the same problem can start it and put it in gear and it is fine but if i leave it to warm up and then try to put it in gear it shuts down.

try checking the temperature sensors this is what tells the fans to come on.
