1998 Yamaha YZF-R1 - Answered Questions & Fixed issues

Question edited for clarity to add maker and the rest of the model! Question moved from Cars and Trucks to correct category. 1998 and 1999 are the same bike. From 2000 the engine management system was changed. https://en.wikipedia.org/wiki/Yamaha_YZF-R1 ..

Should be easy enough as a 1998 Yamaha R1 already has a 6 speed gearbox as stock

Depending on the climate that you live in. Cold temps SAE10W30SE to hotter climates SAE10W40SE. Hotter climates still and if you can find it 20W40 and 20W50 Off hand, don't know the size of the crush washer. I assume this is for the oil pan drain plug. They are of a very common size and freely available at just about any motorcycle parts store. They are an aluminium washer, not a copper crush one. I've actually never replaced one ever and have never had a leak. If they are a little deformed you can sand them lightly to even them out.

Before you change the oli ,find out where and how theb oil is getting to your air cleaner .

Hi, Sounds like you have a bad ignition switch. Also check alternator, so that battery is charging.
Do a test for me, start engine disconnect battery. If alternator is working you should have light and horn. Stop, engine reconnect battery. This will give you a better idea where the problem lies.
Good luck.

bolt in maybe, Will It Fit... you can do you anything. take your tools and see if the numbers works. The only thing that is stopping you is typing on the computer.
Good luck

Shfiter fork assemblly has gone bad.Need to drain oil and open side case to see whats broken on shift fork assembly.If no motor exsperience dont attempt.Bring to shop.

You need to find source of leak ASAP !
Check the fuel lines, filter etc to see where fuel is coming from.
make sure there are no sparks, naked flames nearby or you will have an ex-bike.

The headlights housing has to be opened and it has to be stick inside
u r doing zis at ur own risk ,its better to contact a profesional

have ya checked or changed the oil if smelling raw may be an issue

just put in three quarts keep bike level start bike for a minute turn off then when its still up right fill it only to 3/4 of the way up the sight glass or stick this will help to keep from over filling. If you over fill you case the crank splashes the oil around and stirs it up and make bubbles or air particles and this could damage your main bearing so its always better to under fill than over fill.please rate my expertise i like to hear feedback.

the lid for the air filter box, try lfting it upwards, or moving it sideways, sometimes they have small tabs, or locating tabs on them. check to see if you have removed ALL the screws. something is stopping it should come off,, sometimes the seal sticks, you may need to tap it, or use a screwdriver to lver it off.

dont need owners- u need a haynes or clymer repair manual

set the twist-style spring preload adjuster to its lowest setting.adjust the front telescopic fork adjustment, Or change the tire aspect ratio(lower profile)on the rear.

Not worked on this model ,but I believe the alternator is fitted on a taper shalf ,and needs a puller .ask your local yam dealer if this is correct .

"""an oil change will fix it?" not a chance,,,sorry you have a worn second gear in the box,,,but fell free to change the oil, it just wont fix it, second gear is the one that takes all the hammering when its getting caned from a stand still,, like 0mph to warp 9 in ten feet! its an old gear box now and its showing its age
