    Yamaha VZ150TLR Questions

    injected motors have a fairly sealed system on the motor, so it should not evaporate away like carbed motors. but it is always good to run them from time to time to make sure fresh gas gets thru the system. gas in the main tanks is a different story. non e fuel and stabilizer is a good idea...

    2002 Yamaha hard start

    he did not ask about starting the motor. he asked about why the heater was not getting power from turning the key or pushing the ley in to get power to it. it does not work that way

    2018 Suzuki 115hp

    I now very little about that Suzuki, but with most all injected motors the idle air control valve can hang up and not be noticed by the ECU, but may hurt the ECU by drawing too much current from constantly trying to change its position, but does not monitor if it is actually moving. and all...

    2006 Yamaha 90 2 stroke

    that means unburned fuel is getting in the exhaust and then igniting. need to make sure all plugs are sparking

    2006 Yamaha 90 2 stroke

    CDI should control the timing as long as you follow the procedure for link and sync in service manual. all 3 carbs need to be exactly the same closed on the carbs and setting the timing with the linkage is part of the link and sync could be a lean sneeze instead of a back fire you were...

    2006 Yamaha 90 2 stroke

    make sure the compression, spark and timing are good, if so then that leaves proper fuel to air ratio to chase down needles and gaskets are not the only thing in carbs that can have problems. jets and passages all thru them need to be clean

    F115TXR Starter Click

    most problems like that are bad connections . battery terminals not making good contact to posts and then arc a little getting a better connection. pull and clean the connections to see if keeps it from happening again

    1994 Yamaha 4hp 2-stroke tuning.

    a motor that has set up for long periods of time usually end up with carb problems. hard to drain all fuel out of carbs, pump, and lines so when the fuel evaporates it leaves residue that plugs things up. my guess would be carb needs proper cleaning and setting

    2006 90hp yamaha started running rough after 1/4 mile from dock.

    so is it still having a problem after almost 5 years

    Thermostat housing hole.

    if that is a 3 cylinder motor then it is not a waste spark system so each plug should fire just once

    Thermostat housing hole.

    some of those inductive tachs have a problem with interference from the other spark plug wires . also sounds like a lean sneeze happening that causes the motor to kick hard and die

    1983 Suzuki DT-60 Outboard Not Running Well

    I would check compression, spark, and timing to make sure it is still in spec. something has changed that should not have without someone moving things. or an idle circuit in carb has plugged up or a vacuum leak somewhere.

    Yamaha 90 tlr not shifting

    can you explain what you meant by no rev?. I thought it meant the motor would not throttle up in RPM never mind I just realized it was no reverse, my mistake. many years ago I came across a shift cable that had slack in the movement of the inner cable. I have no idea how that could happen...

    Yamaha 90 tlr not shifting

    apparently something is coming loose to cause the motor to not shift and operate the throttle as you move the controls. how else could that happen?
