Question about 1980 Yamaha XJ 650

1 Answer

My son has a 1980 650 Maxim. We changed the oil about a month ago and then noticed the bike burning oil but it never has before but then it stopped. We checked the oil and it was full. On a recent trip the oil light came on and he had to add a full quart of oil. We just checked it after a week of sitting in the garage without driving it and the oil was low again but it is not leaking any oil.

The problem is with the piston rings.there are three or four rings on the piston which is according to the power output of engine of the bike.
each ring has its own purpose ,and one of the ring is called oil ring.
I would recommend you to change all the rings because they come in a complete set.

do this and your problem will be solved.

Oil pressure indicator/engine won't start

I would drain the oil and refresh inc filter, take all plugs out and spin it over with new oil fitted and filter, if it feels sounds tight, squirt some WD40 in the pots, spin again if looser maybe a strip down eh.

I own a pulsar 150 UG4 2010 model since april 2010. Since then i notice that my bike gets over heated even in short trips say less than 15-20kms at a constant speed of 60-65km/hr. and burning smell comes...

check your spark plug and see what color it is, it sounds like you might be running really lean and that will cause the bike to run hot. if the plug is white or lighter in color thats most likely what is happing.

How many quarts does the 1982 Yamaha XJ-750 maxim take to do an oil change? I did change the oil filter too! Also, do you know where I can get an owner's manual?

I have an 85 700 maxim so I should think they are about the same. It's not hard as long as your exhaust is not in the way, I can't remember I change the standard exhaust a long time ago. The drain bung should be between the second and third down pipe on the underside of the engine, loosen anticlock and drain oil into something with at least 1-gallon capacity. The filter (on mine anyway) sticks out from the front of the engine at the bottom again between the two middle down pipes, as far as I remember a 10mm(3/8) socket or spanner will take the casing of to allow you to change it, well worth doing at the same time as the oil (no point putting fresh oil through a dirty filter). So when you're new filter is on and your drain bung back in put the bike on the centerstand on level ground and fill to the mark with fresh oil. Then start the bike and allow it to idle for a few minutes. Stop bike. Check oil level after 10 mins or so and top up to the level again as your filter should now be filled also and will leave a little less in the sump. If its no different don't worry just check it again after you have been for a ride just remember to give the oil time to settle back into the sump. The best time to check oil is before you start the bike from cold

Lifter noise

Could be that the bike has been ridden a little hard; could be dirty oil. Put a cleaning additive in your oil, idle bike for 10 - 15 min drain oil replace filter, add new oil - good stuff- and see if they quiet down.
