I have a 1983 650 Maxim with 70,000 kms on the odometer (about 43,000 miles). I'm rather pleased with how the bike runs. I don't do work on it myself but it gets a tune up each year or so. Never had a problem with it. It does need new pipes though. Lots of rust, lots of holes, lots of noise. The baffles are pretty much gone.

What I'm wondering is what more can I reasonably expect from this bike. 43,000 miles is a lot of miles. Should I be investing hundreds of additional dollars in this, or just start saving that money for my next bike? Any opinions appreciated.

I have a 1982 650 Seca. I am the original owner and have about the same mileage as you - just over 70,000kms.

My bike burns no oil, and still runs very well.

The XJ mileage recored holder,to my knowledge, is a 1982 750 Seca.
It just turned 250,000 kms, and has the original rings, pistons and valves.

in June and his bike purrs like a kitten.........Kliph

My '79 XS100 had over 50,000 when sold, and was still going strong. My '81 750 Seca had over 65,000 when I traded it in on my first Turbo-Seca (that one was stolen with less than 1,000 miles on the clock). Insurance bought me a second (two weeks before Yamaha dropped the price from $4,999 to $2,999), and it had over 70,000 when I finally sold it. Yamaha builds a good motor. Change the oil frequently, and have it analyzed on an EGA every few years. Carburation on these is generous, and they will still run even if the carbs are getting gummed up, but will run lean and hot, reducing engine life. Easily made worse by airleaks from dried out carb spigots. EGA can spot this lean condition fairly early, well before damage occurs.
