    df9.9 runs for 5 seconds

    does it keep running if you throttle up some? does pumping the primer bulb help to keep it running? I know nothing about that motor, but some motors adjust timing and enrich fuel during start up. timing is easy to check with a timing light, but I have no idea if or how that motor would add...

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    not sure where you are getting the 3 phases from, there are 2 charge coils. one for slow speed of the motor( starting and low RPM, and then the high speed coil for higher RPM. Not even sure how many caps there are in the CDI for that motor. have you seen something to show this info? I was...

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    Boscoe posted good info on how it all works. what you call the stater is the low speed and high speed charge coils. were you testing them at different RPM to see if they made spec in manual? you need to post what the specs are along with what you are reading, even for the pulser coils. It is...

    Year of my yamaha 25 hp ?

    Q says it is a 1992 model. manufacture date may have been in 91. should be sticker on the other side of motor with the date of Manufacture.

    2003 Z250 Overheating

    if the PCV is stuck, there is a very good chance that the motor has a lot of mineral build up in the cooling passages. pull the stat out and inspect the passage and test the stat while you have it out. might need to use a chemical descaler to remove some of that. and hope that also allows you...

    low compression #2 cylinder - 1988 suzuki dt85

    just rig up a hose to the pipe heading up to the powerhead that the pump normally hooks to and turn on the water before starting what was holding the powerhead from coming off?

    still need to test the stat to make sure it is operating within specs

    stats and water pump would be the 1st things I would look at

    2003 ox66 200 intermittent shut down

    no I do not, but if the pump can pump higher pressure and the rail regulator is dumping too much pressure, I would think a new pump would not help

    2003 ox66 200 intermittent shut down

    are you sure you gauge is correct? does the pressure spike when you 1st turn on the key/start and then drop back? I believe there should be a pressure regulator that controls how much to recirculate back to control pressure in the rail

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    This is good info. I have a feeling the OP has not measured peak voltages, just ohmed out everything. but I could be wrong. still does not make sense why swapping the brown and blue wire on charge coils moves the miss from #1 to #3 I guess that would change the polarity maybe. but I would...

    low compression #2 cylinder - 1988 suzuki dt85

    most all motors I have messed with had a shift shaft you needed to disconnect in the lower part of the lower unit. some needed the water intake screens removed to get to the coupling or some other area. But I have not played with many Suzukis

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    this drawing shows 4 wires for the pulser coils and 3 for the charge coils. charge coils have a common between, but pulsers show totally separate from each other. Does your manual show something like this with wire colors on those wires? you said green wire, but I am sure you meant white with...

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    Yea, my C40 has 3 pulsers coils one for each cylinder. that makes more sense than all this other stuff added to mystify the way things work. So if that C85 has 2 pulser coils should that mean #1 is run off of one and #3 run of the other, since swapping the brown and blue wire makes the miss...

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    probably at work back before 2006, but I did not create much with it I am surprised to see just one pulser coil on that 90

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    I missed it earlier, seems he just swapped the brown and blue wires from stater to CDI. red stayed the same I have no idea what those 3 wires are from. charge coils or maybe charge and pulser coils looking at a parts drawing/pic the stator seems to have 2 charge coils and 8 lighting coils...

    Tricky Yamaha C85 Electrical Problem - 1 cyl OOS - Problem Rolls with Stator wires but new stator - Same issue

    just for your information, the lighting coil feeds the rectifier/regulator to charge the battery. charge coil feeds into the CDI to charge up the capacitor for ignition system and so does the 2 pulser coils
