so i had my 87 vfr 700 running for a few weeks and after running thru about 1 tank of gas it started to sputter and died. since then it never started up again. thought it was the carbs, cleaned them and tried again, no luck. checked the plugs today and they are getting no spark. i read a few threads on here about the ignition system failing, but a few said to check the pickups on the sator, when i removed the flywheel cover there was about a pint of oil inside, im guessing this is not normal and may be the root of my problem. just wondering what i should do next and also what other problems could be causing the no spark issue.
thanks
John

If you are reffering to the Round cover on the left side of the bike then it
is normal for oil to come out when it is removed.....especially if the bike is on the kick stand and leaning to the left.
yea it came from there, i guess it isnt uncommon then, i havent ever worked on bikes before now, just on 2 stroke jetskis.
how can i lock the crankshaft so i can get the nut off the flywheel? i have the plugs out now, should i just put them back in so i get a little resistance from the compression?

Hold the flywheel with a gloved hand, remove the nut with a rattle gun.
Before you start pulling off parts, I sure would check the connections at the battery, at the solenoid, at the coils, and the plug wires and plugs first....do the cheap, easy stuff first, then start pulling the motor apart.
One tank of gas: You think there was water at the bottom? Crud or rust in the thank that is now in the carbs? Is the fuel filter intact?
so after a few busy weeks i finally got some time to take a crack at the bike. after about an hour of trouble shooting, i decided to go buy a new set of spark plugs. and BAM! as soon as i hit the starter, it fired up. as a bonus, the idling problem i was having before has been eliminated. took it for a ride and it is running pretty nice.
now for the next issue, the Tachometer, its not working at all. how can i begin to troubleshoot this one? i checked the connections in the back of the dash and they are all connected and corrosion free. is there some sort of sensor on the motor that could have gone bad?
