Methinks the speedo head is lazy. Defective. Verify cable and drive have adequate lubricant. - Ned

1989 yamaha waverunner. I purchased a 1989 25HP Yamaha Waverunner & was wondering how you check the engine oil?

Did you get any instructions from the previous owner? If it's a 4 stroke waverunner there will be a dipstick on the engine block, but I'm guessing it's probably a 2 stroke engine because most watercraft used 2 stroke motors clear through the 1990's. The oil will be mixed with the gasoline when you fill it, bottles of 2 stroke oil can be purchased at most stores that carry oil. Your waverunner can be mixed at 50:1, which equals out to be 2.6 oz of oil per gallon of gasoline. On a 2 stroke engine the engine gets lubrication from the oil mixed with fuel and will burn up fast if straight gasoline is used. Let me know if you have any troubles, but try to get ahold of the previous owner to get some more info.

If the speedo gear is in the front wheel a different wheel would have different gear and mess up the speedo but I'm thinking the gear wouldn't mesh with the old speedo cable teeth.Check a shop manual for stock number of teeth on rear sprocket and tranny sprocket,that will tell the story.While your at it check the stock wheel size compared with what you got.Of course it could be bad speedo.There's springs in there that run needle, so?Maybe borrow one and try it out.Good luck.

II have a waverunner jp 1200 97 and did not startet and i took the battery and now the clock asked for a code

If you did not previously have a security code set, you will need to set one at this time. It is an easy procedure. First, open the front hatch and remove the storage trunk. Find the group of wires coming out of the handlebar assembly. In that group, locate the blue connector with only one wire in it and disconnect it. Now, look at your multi function meter (speedo/tach), you should see the red warning light at the top between the two gauges lit. Hit and hold the mode button until you see the word "CODE" on the right gauge. At this point, enter any 4 letters you want as your security code by using the letter buttons on the right side of the MF meter. You should see them taking up each of the 4 blank lines as you enter each letter. After you have entered your 4 letters, re-connect the blue connector, put the trunk back in and close the hatch. Now your waverunner should start. If it does not, hit and hold your mode button till it says CODE on the right gauge again, and enter the same letters in the same order that you stored them, now it should say START. Hit the start button (with the safety lanyard in of course) and your engine should crank!

Y wont my brand new xr250 2005 model go faster than 90kms

It is possible that your bike has been governed from the factory to only reach a certain maximum RPM, they do this so you don't inadvertently over rev the engine and blow it up.

If the bike is not governed you might have to re jet the carb, altitude and other factors can change your fuel/air requirements and cause improper operation of your fuel system therefore the maximum RPM.
