I know your comment was two years ago but maybe this could help someone else reading. There is a wheel located between the number 2 and 3 carbs; it's your idle adjustment. Counter clockwise turns down the RPM, and clockwise ups the RPM.

Bikez.com has all the info you need for these. Just go down their list of Yamahas.

You need to have a bigger draw; most make the mistake in going low amp draw LED, and find also the charging system may not like it as well. Go back to regular 1156 or 57.

I'm having the same problem. I've been looking for one for over a year and a half; it's just best to make one out of sheet metal with some shears and spray paint.

Just bought a 1982 750 Maxim with a little over 5000 miles on it. The bike runs great and is all original. Just have a little trouble getting used to the clutch; real touchy, but a great riding motorcycle. Fast and nimble around town.

Look on eBay, they are on there all the time.

I bought my 82/XJ750 Maxim last summer. I cleaned the carbs, bought a new battery, and the baby was on the road and running great. Unfortunately it was short lived; it starts fine, I can raise and lower the RPM just fine, but I put it in gear and hit the throttle, and it barely moves. I can get up to maybe 15mph. If anyone could help point me in the right direction, that would be great.

These bike have an oil bathed (sp) clutch. When they sit for a long time, only half the clutch is submerged and the other half dries out, and rusts or gums up. It's a simple clutch job, change it and you're good to go. Also, check out the XJBikes web site. There is a load of information there.

I have a 1982 Yamaha 750 Maxim and it runs great other than I can't keep it idling without the choke on. Do you think this could be my problem?

Hey man, I'm in the same boat and can't find parts. If you find a source, please let me know. benrmartinez1978@gmail.com

Mine was doing the same thing; it was the that carb clamp on the boot nearest the throttle linkage. The throttle linkage was hanging up on it sometimes. I just loosened the clamp and turned it a little and that fixed it.

Just bought an all-original 1982 Yamaha 750 Maxim with factory fairing and hard bags. One concern... the owner passed away, his son decided to change the oil & filter for the new owner. He used Castrol 2T synthetic motorcycle oil. Clearly this is 2 stroke oil meant to go in dirt-bikes, to be mixed with gas. Only a few miles were were driven like this.

Question: how much damage to the engine has this mistake made?

Thank you.

Go on eBay and order a pair of "Resistors". These are made to create a bit more current draw to your turn signals to activate the stock turn signal relay. These resistors will be place in the headlight wiring junction, and one wire from each resistor will be tied to the hot lead of each front turn signal, and the other wire from each resistor will be tied together to the neg. common to both lights. These resistors are sold specifically to resolve the LED lighting issues.

It's 4 years after you placed you question and I don't know if you solved your problem, but I thought I would send this along. It seems that the right side cover flies off more often than the left and consequently is harder to find. Try eBay motors. You will see a lot of right side covers and a few left sides. Expect to pay a premium price. Also eBay motors is a great source of used parts of all kinds for this bike. Good luck.

Hey John in Alabama.

I have a 1982 Yamaha 750 Maxim in very good shape, garage kept, 31000 miles. I know it's been 7 years; still interested?

Make sure your kickstand is up when you put it in gear; it'll die on you when you put it in gear if it ain't; you have a safety kickstand on it.

He's got this exactly wrong. Left side covers are easy to find on eBay, but not cheap. Right side covers are nearly impossible. I've only seen one in three months of looking daily.
