Question about Yamaha YZF-R1 Motorcycles
I have a 2001 Yamaha R1. I just purchased the bike. It has 45,000 miles and is in pretty good condition. I havent had very much ride time due to weather and work i've doing on the bike. I've purchased new fairings, repaired, replaced, and repainted many many things to get the bike to my likes. Here is my issue I have a idling problem. When I got the bike home i noticed it was running very rich to the point you couldn't hardly stand next to the bike running in an open garage due to the fumes. So, I changed to the oil which looked way over due then the spark plugs, cleaned the air filter.The fuel filter is fairly new and clean. I also sprayed the carbs out with carb cleaner while they were on the bike. When I cleaned the air filter I noticed a small amount of oil through out the airbox. After replacing and cleaning the parts that needed it I moved onto adjusting the carbs to take care of the rich running issue. I am an Auto tech and have about 15 years experience with cars and a couple bikes. More then capable of completing these tasks, also my Father has helped me with this project as well. He is a Master Auto Tech and has been for over 30 years. Enough with my life story and to the point. LOL I removed the crank case vent hose which attaches to the airbox. With the bike running their is quite abit of smoke and pressure coming out of the crank case tube when I hook it back up to the airbox the bike will start idling bad and die after about 10-20 seconds. Also after the bike arms up a relay starts clicking and the exup controller acts very erratic. I have read many forums saying clean carbs and jets, that the rings are bad, and to the point of making some type of system to take the crank case vent hose and make something to dump it the exhaust or some type of filter setup. Can you please help me. I've poured alot of time, money, and hard work into my bike. I can't even explain how upset I will be if I can't even ride my bike and show off all my hard work when the weather permits. Which will be very very soon here in Louisville, KY. Thanks to all for their help and suggestions. I really hope that their is a cheap and reasonable solution to this issue.
WELLLLLLLL! SOUNDS LIKE YOU AREN'T FINISHED SPENDING MONEY ON THIS BIKE (ANCHOR) LOL.
do a compression check. Sounds like a piston, rings or both. Probably not valves.
The air/oil being blown into the intake box is the same as the PCV system on a car. There will always be some but not a lot of blow-by in an engine like this.
good luck, it's not as bad a job as it sounds.

The pilot jet controls the idle. Check your service manual for the jet location. Chances are the jet is plugged up by varnish. Count the number of turns as you turn the adjuster screw INWARD until it LIGHTLY seats. Now remove the adjuster screw. Clean the jet and then put the adjuster screw in and LIGHTLY seat it. Turn the adjuster out the same number of turns as originally counted. Don't seat the screw too tight because you can screw up the jet if you do. Remove the actual jet only if you must.
Please rate this answer. Thanks Shawn! Good descriptions :)

If your jetting is too rich it will be extremely hard to kick start it and will most likely flood it from kicking.First thing i would do is pull the top of the carbs off (cable,slides and needles) and see which clip they're set at. If they are set stock which would be middle clip then lower the needle one clip. This will lean the mix out and should start up easier with no problems,The idle issue is most likely just off.If your fiance still has the TORS on it then on top of the carbs he will see 2 dime size and screws and wires as soon as he takes his seat off.While running he can turn each dime size screw in or out to adjust the idle. If it has a TORS elimator kit on it then he won't have all the junk on top of the carbs and it will be just a cable and round cap screwed directly on top of the carbs and the idle screws will be on the side of each carb (brass color screws with nuts to tighten) same thing...in or out to adjust the idle where needed.Hope this helps.

When the carb was rebuilt it was only bench tuned. It is always wise to tune them once installed. the smoke may stop after the carbs are adjusted. However white or light colored smoke is always an indication of oil. It sounds like you may have a small leak. Hope this helps. Good luck.

The idle problem is a lean fuel mix caused by an air leak in the intake system. Bad gaskets /seals on the intake manifold, bad valves, bad piston rings, loose spark plugs, and bad head gasket are all things that can lean the fuel/air mix. The smoke indicates a need for new rings. I would have the cylinders bored then install new pistons and rings. Now finish the top end work by getting a valve job. You should get a liquid fuel tank liner to eliminate any rust problems in the future. Also, install an in-line fuel filter.
Google “ kreem fuel tank liner “ or go to www.http://www.4secondsflat.com/Fuel_Tank_Sealer.html
My complements on the well cleaned carbs. Do the work mentioned above an you will effectively have a new engine.
