Does oil need to be around pick up coil on 1200 suzuki 2002

check oil breather pipe in airbox

you will need a factory service manual from suzuki. should be around 75 bucks at the suzuki dealer

The settings are not that critical for theair screw. Start with it between 1.5 and 2 turns out. With the engine warmed uptry turning it in or out until you get the fastest or smoothest idle.
The factory setting is only a startingplace, the adjustment still needs to be made to suit the elevation of thearea you live in.
The idle can also be adjusted for yourown riding tastes, around 1200 rpm should do

What about your carb, fuel filter and air filter?

Check the Compression in all 4 cylinders, if the compression is low on one cylinder, squirt some oil or or WD40 down the bore and immediately recheck the compression. If the pressure goes up a fair bit you have a broken ring, if not you could have a burnt valve. If your getting fuel in the oil it definately sounds like a ring problem

I'm assuming that it has been sitting for a while and now it's stuck. Do you have oil in the reservoir? Pressing the brake lever should be able to force the piston out with no problems. Otherwise, try to get the seal out from around the piston, and spray some anti rust lubricant and let it soak.

no the oil pick up is differant

i would think its the coil as the cdi in this model was a good unit
