Question about 1981 Yamaha XJ 650

1 Answer

Hello, i am trying to find out if carborater diaphragms from any other bike would fit my 1981 Yamaha 650 Maxim? I was told that they can from a HONDA VF750 MAGNA 750 VF, or a 84' 86' VF500F INTERCEPTOR, 84' 85' VF500C. The measurments for these are INSIDE DIAMETER 30mm, OUTSIDE DIAMETER 65mm. If anyone can help me it would be greatly 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

if its an A its a 1980 model, B is an 1981, C is a 1983.

the 4H7 in the VIN means its an XJ650H model made in 1980 & 1981, Look up XJ650 on the net for more info on your bike.

Oil blowing out of trans breather tube

hi 81 yamaha i am concerned about the fuel smell coming out with the oil. could be the carbs flooding filling your crankcase with fuel? if not it sounds like you have blow by which would cause your crank case to be slightly pressured. this is caused by worn piston rings. do not plug your crank vent. if you leave your vent open install small filter to stop dirt from entering jim
