2002 375 4x4 auto. 3300 mile 145lbs compression, (valves checked at 2500 mi but never adjusted.
It has spark but wont run or fire even with a shot of gas in cylinder.
I pulled the side cover and all the magnets appear to be equally spaced on the flywheel. Stator looks untouched
Trigger coil green to blue wire=178 ohm,
Source yellow to white wire =0.1ohm
Charge coils 3 black wires any of the 3 ways 0.5 or 0.6

Primary (coil) .1 to .2, secondary 16.3 K ohms Spec is 4 to 9 K ohms.

I need a new coil, the spark looks good with the plug out and grounded but way out of spec.
Also I guess it would be prudent to dump the old flywheel anyway before it flys apart and eats the stator.
Do you think that is all that is wrong?
Anything else common besides the magnets?
How many miles before valves start getting too tight on these? Seems to me a 2500 mi they were so close I just left them alone.
Thanks in advance.

Not sure but you can also post this on the Suzuki forum since its the same 376cc Suzuki built motor used in the 400 Eiger and King quad for over 15 years.

 

See if you can slide/move any of the magnets with your finger. Also check for glue spots. If I remember I don't think the spacing is even.

 

I would and go adjust you valves before you do anything.. What you think may be close could be a huge difference on the machine.. Also don't forget the tighter they get its starts slightly messing with the timing of things

 

The valves were good, compression 138lb, manual says 66 to 77 or something, sounds like a typo maybe,,missing 1 in front? Anyway, new plug, coil an plug cap fixed all but a occasional lean stumble on idle. I change the flywheel as a preventative measure.
But some miles on and see I guess.
