Hello, I have a DT200 from 1998, these motors are amazing - never had any problems exempt this. Love Suzuki! And I thank you in advance for reading my lengthy post!!!
The motor does not fire the 3 left cylinders. Now here is the weird part - if I cover it up nicely as to protect it from cold/rain/weather, it regularly works great. However if left without a cover ( just the engine cover of course) and part of my boat cover that goes over the engine.. the problem appears and it needs to be turned on and ran with just 3 cylinders (for up to an hour sometimes) and THEN all 6 start to fire.
Today:
I went out to check it out, on the first crank - 3 right cylinders, so I started to check sparks - no sparks on left side, so I came in and read everything I could find about this sort of issue...
These are my findings -
1, the "low oil sensor" may be interrupting
- However if this was the case I'd think all 6 would stop firing
2, the strator ( coils - high or low ) could be damaged
- Does not seem likely to me since the motor idles beautifully once all 6 cylinders start to fire. ( and accelerates and reaches high RPM nicely also )
3, neutral switch
- Again, if this would be the case.. I'd think none would fire.
4, CDI ( which I read cannot be tested)
Later went back out.. cranked it.. and just as I was going to start my diagnosing, they all started firing ( I had it covered since 2 nights ago when i cranked it and the left 3 cylinders would not kick in )
First question -So the issue will have to wait until tomorrow when and if it presents itself again, I was not able to diagnose CDI by switching the coils from the right cylinders to the left. However, once the problem returns, can i just put the coils from the right cylinders in order on the left bank, without causing harm to my motor? I mean switching the spark coils 1,3,5 with 2,4,6 .. will it cause any timing issues?
Second question - Which of these problems seem more likely to be the culprit? Taking into account ( highly ) that it happens when the engine is not protected from the environment?
Third - Could anything else be going on that I have not mentioned here?
Lastly... Thanks So Very much!
