20 Most Recent 1998 Yamaha XJR 1200 SP Questions & Answers

On older bikes the starter switch can start sticking and not fully return. The headlamp is commonly cut during starting to allow more power to the starter motor. But if the start switch does not fully return it can keep the headlamp off. Try juggling the switch with the bike running and see if the lights return. If they do then its time to take the switch apart and give it good cleaning and lubrication with electrolytic grease. MGM

have u checked the clutch is free , try putting in gear and pull the clutch in and push the bike and see if clutch disengauges ( engine not running ). if all ok then strip carbs and clean jets etc !

Some Yamahas are designed to shut off the headlight while cranking starter to conserve battery power.
I'm not sure your XJ was built that way...but other models have the same problem.......
The starter button has a set of contacts for headlight, and a set of contacts for starter circuit.....as you push in the button, the headlight contacts open first...then as you push further the starter circuit contacts close to crank the starter. If the button does not fully release after starting the headlight stays off. So try WD40 around the button edges and work the button in and out several times with key off, then see if your headlight works now.

yes carb jets probly need ajust or it needs total cleaning-passages are blocking causing delay in fuel--buy a clymer manual for procedures

Im sure the filter is located at the lower left hand side

Have you changed the brake fluid complete by getting all the trapped air and gunks out?
If you have done that, then remove the brake pads, force piston to come out more, clean around them with Brakleen spray and around piston seals, wipe with clean cotton cloth or use compressed air to ensure that piston surface is very clean and nothing stops free piston movements. Press piston in as close as possible to caliper wall, spray again with Brakleen then air dry to blast all dirt away. Do these 2 to 3 times then assemble everything back and try to see if piston still stuck. If it gives tight friction grip it is now fine, just spin the wheel and you should have a little friction but the whell should be able to turn at least 2 free turns.

no. the brake master cylinder is for the brake calipers on the wheels. if your brake light is not working and the bulbs are ok. check the fuse box under the seat. or the connectors to the brake light assembly.

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.
