Question about 1981 Yamaha XJ 650

1 Answer

650 maxim keeps reving up

I bought this motorcycle at a sale. it runs but it keeps reving up instead of idleing. I've put new intakeboots on and new needle and seats in all the carbs. but the problem is still there. Also seems like No 2 cyl is not hitting I get no change when pulling spark plug wire off that cylinder. I did a compression check and had 70 in that one and 90 in the others.is this too low of compression?
Any advice giving would greatly be appreciated

My 1981 maxim 650 idles high. what is the correct idle setting and how do i adjust


Hi, Robertshenk and the usual suspects are:
1. Throttle cables improperly adjusted or pinched.
2. Idle adjusting screw needs to be backed off.
3. Intake system air leak.
4. Fast idle choke ramp is not releasing.
5. Broken throttle return spring.
6. Damaged diaphragm or slide.
7. Faulty MAP, TPS, ATS, O2, VSS sensors or wiring/connector

Greetings all. Bought an 1983 Yamaha XJ650 Maxim late last year and love it. It ran great last fall and took it on a 2500 km road trip this June and it ran great. Two days after I got back it started...


Have you changed the oil and cleaned the air filter, after the fuel tap problem.
fuel in the oil can cause this symptom. the fuel ends up in the sump when the taps fail as yours did
also check choke is not stuck open, and battery is in good condition

1982 XJ 650 maxim cylinder 2 & 4 won't run


Are you saying that 2 & 4 got gas with external tank but not with gas tank? If so something else has happened ,if gas is getting to the carb it cannot by-pass 2 to get to 1. Take the tank back off ,connect to external, again. See what happens.
