hey, i recently inherited my harley from my grandfather who passed in dec. 08. about a month ago i was riding and made a turn and got into the gas and right as i shifted she lost all power and started sputtering. wouldn't run right since. fouled plugs after 2 starts right after this happened. took the pugs out and grounded, and the firing pattern is so spuratic. it'll fire fine then the back sylinder will stop and then the front as well. then back will and front won't. then they both won't for about 3-4 rpms. any ideas?

A few things can foul plugs, improper plugs or gapping or rich mixture or a weak coil. You have to figure out which one is doing it.

Could be the crank position sensor causing the problem . It can be tested . Located in the crankcase to the left of the oil filter . Follow the wire to it's connection . Unplug the connector and test resistance ... should be 1000 - 1500 ohms , anything else and it's bad .

k, i keep my bike at my father in laws shop. yesterday i went there and somone had drained the oil out of the bike. when i parked it there it was brand new oil and slap full. went back two weeks after that and was full then too. now 3 weeks after that its bone dry and no leaks or oil spots on the ground. ( don't trust anyone with your shit, you'll get screwed family or not!) so im just gonna take it to the shop and have it totally checked out and make sure that there isn't anything else wrong or messed with. thanks for all your input.
