2005 Yamaha YZF-R1 - Page 5 - Answered Questions & Fixed issues

The error code 12 on your bike is a crankshaft position sensor malfunction. Just means you should replace that sensor.

This is just a guese ive never worked on a R1 but most bikes are similar with chains.

Firstly to loosen the axel and the chain tightners and pull the wheel as far foward as you can. then to find the master link in the chain its a funny looking link with a clip on it, it might not have one if its a compressed link chain, but for this sake lets hope you have it, when you find it use some needle nose pliars and take the clip off and then pull the link outwards it will come off like a washer and push the other side out, theres the chain broken so it can come off, its its a new chain your installing you could cut the old chain off with a hack saw or grind on one of the links. as long as the new chain comes as one long peice not a circle with no master link.

to get the sprocket off the front find where the chain goes too and un bolt the cover for it it should not be water tight. then the sprocket will have a Circlip or a bolt on it, if its a circlip get a flat screw driver in the space and turn or use the right tool. if its a bolt nock it in gear and try to undo it with a ratchet if it just turns the engine you will need to undo the timing plug on one side of the engine and put a ratchet on the flywheel while un bolting the sprocket you could also do this while the chain is on the bike and put the rear brakes on and un bolt the sprocket, this will stretch the chain but your changing it anyway.

new sprocket is same way just slide it on and clip or bolt get your chain all the way around all sprockets and the master link will probly be an O-Ring chain, if so you need some vice grips and a 8 or 10mm nut or a 1/4 american nut and you put the rubbers on either side and the plate
and put the nut over the link heads and clamp down til the clip slots are showing do this to both sides of the link. then put your clip on with needle nose pliars and pull the wheel back with the chain tensioners and tighten your axel
you want a bit of play with your chain so it can stretch when you sit on the bike, you will need to tighen it for a few hundred miles dayly while the chain stretchs and wears in.

i have a complete 2005 r1 factory service manual from a yamaha factory training facility. just send me an email of what you need and i'll scan the pages into my computer and email you back what you need.my email is [email protected]

Take the pipes back to the maker and tell him to put one on.Otherwise you have all sorts of problems.Really.Hope this helps

The bike has a computer sensor system and it is trying to let you know it has detected a problem in the injection system. If it were a "fatal" problem it would not let the bike start. Take it to a dealer and have them hook it up to a code reader. The reader will let you know what is wrong and at that point you can decide if you want to fix it yourself or have the shop do it.

Go to http://www.carlsalter.com/motorcycle-manuals.asp , and download a (free) manual. There are no 2005 listed but an earlier year should give you a good guide.

almost same,

else, get a service manual for the unit

Drain the oil and water. Remove the radiator and exhaust pipes. Remove the oil pan on the bottom of the engine. Remove the bolts holding the water pump/oil pump on.
Here is a diagram of the oil pump/water pump:

Sounds like the cam timing is off. Double check that.

hi buddy take it to a garage and get them to adjust the tappets i have exactly the same thing on my gsxr1000 ticking noise

does it have a fuel pump ?...it could be just priming itself..when the pump is already full you cant really hear the noise that much. Does the noise go away after riding for awhile and then restart it?

Check the starter solenoid.

Sounds like the temp sending unit went bad and when they do it wont let the bike start cause if it goes bad while riding and the temperature goes up the computer shuts the bike down before you over heat the engine and trash it. Try disconnecting the battery and reconnect it after you replace the Temp sending unit.

Make sure your using a high octane petrol because 91 octane can be insufficient for lubrication and cooling that petrol provides. This is very significant on a high performance bike like yours.

Question- did you also mod the intake? did you remap the fuel injectors to compensate for more air?

It really sounds like you need to do those two things before tearing into the engine.

do a cylinder compression test, but really doubt that is the problem

Have a look on the shocky.Where the spring covers it,there will be a threaded area.You need to wind up the plate that the shocky sits on.This will increase the 'preload' on the spring allowing for more weight on the bike.It is always different with 2up.In the toolkit,there should be a 'hooked' tool to adjust this plate.Hope this helps

This sounds very much like a blown head gasket. It should be repaired immediately to avoid engine damage.

you may have a bad pulser coil or pick-uo coil
