Hi, Anonymous there is no such thing as a weak spark even though dozens of riders will swear that's what they have and are dying to show you, the bottom line is either you have spark or don't have spark there is no in between.
You won't see a dirtbike spark really well, and people only look at it when they have a problem. It is designed to fire under extreme pressure (13:1 compression) and is very robust, but it is not a 1mm bright blue line jumping across a spark plug. It can be white and very hard to see. If you are confident you have weak or no spark prove it by holding the plug in your hand and stark kicking you will be in for a "SHOCKING" surprise!!!!!
60% of these bikes have a flooding issue and/or a fouled plug. 30% need valves adjusted and most of the remaining 10% are something simple in the electrics like a broken kill switch, bad earth on the battery or dead battery, wiring at the steering head damaged or blown fuse.

Hi, Bryan external oil deposits fall into 3 categories:
1. WEEPAGE is the oil that is sweated pass gaskets, seals, o-rings, and crankcase seams, it's covered by dry dust and is normal for older engines with lots of miles, no repair is necessary.
2. SEEPAGE is the same as weepage except the deposit is wet and confines itself to a specific area, the repair is optional depending on the owner's cleanliness criteria, the deposit location and the weight of his bag of "DRACHMA"
3. LEAKAGE is the same as seepage except it is enough to drop to the ground leaving a spot. Repair as necessary.
To find the source of your oil leak, start at the point where you see oil and trace its path going up and forward, blowing baby powder from the palm of your hand will help in those difficult to see areas if there is too much oil present then buy a spray can of engine degreaser apply it to the affected area then rinse off with a pressure wand or garden hose, use compressed air to blow off excess water or just let it drip dry, take your bike for a 15 minute ride and check for the leak.

4. Air leaks: If excessive air leaks into the intake ahead of the impeller, the jet unit will "slip". Possible sources of air leaks are though a faulty gland seal, which is usually accompanied by a static water leak into the boat when standing idle.
So if the gland is worn out and leaking into the boat with the engine off, it can also suck air when accelerating on to plane, and if this happens, then the thrust is reduced dramatically. Air can also be introduced into the system via the inspection cover, so you will want to make sure the cover is tight.

2. Engine Run Switch in the "OFF" position.
3. Engine Run Switch is "FAULTY" or corroded.
4. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter.
5. Bank angle sensor needs a reset or is faulty.
6. FOB battery low or dead.
7. Faulty ignition switch.
8. Faulty starter button.
9. Faulty kickstand, clutch, neutral safety switch.
