Hi and welcome to FixYa,

Initially, pls the Oil Light indicates that the level of 2T oil in the reservoir is below minimum level, pls add.

I could only think of 2 possible limiters:

  • rev limiter since the 2T oil is lit hence the ignition will cutoff at a lower RPM; and/or
  • if it is a Japan domestic model, then a speed limiter designed to warn and cutoff the engine ignition anywhere from 80 to 100 kph.
If you are intending to bypass the cutoff, in some versions, there is a wire from the speed indicator light that goes to the CDI unit. Removing said wire/connector would disable the speed limiter.

Good luck and Thank you for using FixYa. Happy Holidays.

1981 kawasaki 440LTD. Engine oil light stays on. Oil pump good, Sending unit appears OK. Bike runs strong, can't find the problem. Need help

Well if your oil light is staying lit, but your oil pressure is good and you cant find any problems with the actual oiling of the bike, then this sounds basically like either A.Your sending unit is bad or B. You have a ground in your oil sending unit circuit somewhere. You could always replace the sending unit first to save time shooting the wiring harness.if you replace the unit and the light is still on, then you have a wire touching in the circuit between the sending unit and the warning light. I have an 81 KZ750 and my oil sending unit only has one wire going from it to the warning light and the color of it is Blue with a Red Stripe.I am not sure if yours has the same wiring colors though.

The window does not seem to show the oil level. However, the oil light stays on. Do I add more oil or just take it to a dealer or both. Bike runs fine.

If you are down on oil it would be a good time to go to the dealer and have them do an oil and filter change while you watch and ask questions. Then you can confidently do it yourself in the future. Please rate my answer. Thanks.

I need complete manual of yamaha tzr 250 3ma..such as wiring diagram, engine part, etc

Hi, Sam_wicky the vast majority of service, parts, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee around $10 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available, for these rare occasions I shall look on eBay and find the cheapest one available. Most of the manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have. To download your manual please click on the blue links below. Good luck and have a wonderful day Yamaha TZR250 1987 Service Manual
