Question about 2003 Yamaha YZF-R1

1 Answer

Yamaha YZF-R1 Engine noise

In lower engine sounds like rocks or marbles the whole time it runs. Took engine out and new pistons, new cam chain and tensioner, crank and rod bearings in good condition. Piston pin in good condition. Valve shim adjustment perfect. Noise still there.

    did you inspect the oil pump drive assembly. On my cbr when i dumped her in a turn, i got back up and rode it home but the oil pressure light was on and i only had to go two miles home, so i new i had oil, so i just went for it, but the whole time i heard the rocks and marble sound so i took the clutch cover off and saw that the oil pump sprocket bolt had backed off somehow and the chain slipped off the drive sprocket and that it had been riding on that bolt and worn the bolt down and i had a lot off tiny metal shaving in the oil.. so i immediately flushed the oil, purchased new chain and bolt, put back on and got real lucky.

SOURCE: How do I take off the Magneto off a 2003 Yamaha 125

If replacing the piston pin bearing no splitting is needed. If replacing the crank pin bearing splitting is needed. You knew that I am sure but I had to clarify. The flywheel is held in place with one washer and a nut on the end of the crank. Timing is accomplished with a woodruff key on the shaft. Using a flywheel puller tool is the proper method. It is a simple and low cost tool and it sounds like you have enough knowledge of engines to need one now and in the future. In a worst case scenario, use a mallet, striking the flywheel on four points around the perimeter of the wheel and in an "outward" direction. With some luck the flywheel will pop loose.

When you are purchasing the flywheel puller, buy a case splitter also. Also reasonably low cost, it makes the splitting clean and easy. I strongly suggest you install new crank bearings and seals. Whatever caused the crank pin bearing to go bad did not do the crank main bearings any good either. I would hate to see you have to split the case again eight weeks from now.

How are you planning to separate the crank halves, re-assembly and truing of the crank? The dealer should do this part. I can't find a free repair manual on the web but the next best is a parts diagram. Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part, the part is not in stock.

SOURCE: Yamaha Power Valve System

yes you do need a battery, the best position for thr power valve is half open, then once its started turn it either open for bottom end power or closed for top end,i think that right it might be the other way round ant quite remember, but half open should be best for it to start

SOURCE: how much oil does a yamaha yzf r1 2007 take

"most" bikes on average without filter change take anywhere from 2.8 to 3.0 qts. I always purchase 4 quarts because an extra one will always come in handy in the future anyway. First your bike i believe has a sight gauge... First stand the bike upright on a stand or have someone hold it up for you pour in 2 and 1/2 quarts, put fill cap on, start bike, let warm up for about a minute to let the oil settle, then turn off and then start pouring in slowly till it gets to a little above 3/4 full on the sight gauge...you never want to overfill it could cause engine damage. Now just remember how much oil you put in and that is the approx. amount.
