3 weeks ago. I drove my bike from my wife's boss's house to mine after it wintered over there. My bike was acting funny on the way home then it died in my driveway. Today I started to fix it. I pull about 4 dozen acorn shells and what looks like a nest out of the airbox. I figured it died because the junk was blocking air flow to the engine. I slapped it all back together and now I can't even get it to turn over. I own a 84 sabre VF700S with 7100 miles on it I'm the second owner my dad was the first. I'm not sure but I think the engine might be seized any help will be appreciated.

 

Define "won't start"

Electric or kick start? If you kick start it, does the pedal go all the way down, or is it solid? Does the motor make the standard "putter" sound when you kick it? Or, if it's electric, does it turn over?

My guess would be something in the Fuel/Air system is clogged, and/or your electrical system is buggered.

I doubt it's seized. That usually happens rather violently.

 

It's electric and it won't turn over just got done pulling the plugs and there wet and some of them have what looks like mud but smells like gas.

 

ok just so i know "wont turn over" means the engine is cranking but wont fire? the engine is spinning though right?

 

flooded engine. New plugs (splurge or clean em). Choke the bike on cold startup and cut it as soon as it'll idle decent on its own. You may be just running rich but I bet the restricted intake definetely helped you run rich as hell. How did you not notice a performance difference?

 

My bike won't even crank and its not the battery the engine just won't turn over at all. I noticed a problem when I pulled out into traffic but at first I thought it was just cause I hadn't rode it in a year. But it died on the off ramp then it wouldn't idle with out a little throttle then it died in the drive way as I pulled up.

 

I just don't think it's seized. At WORSE, the bike's stuck in gear right now, or your starter's blatto. Does it wheel around like it's in neutral? Why don't you pull the plugs, put it in gear, and push it around and see if the engine spins.

I'm more apt to think the bike needs a major tune up.

Battery blatto, carbs need cleaning, coils potentially dead, plugs need replacing, air filter needs replacement, etc.

Just my gut instinct.

I generally don't see engines seize without something catastrophic.

 

I tried to roll start it and the second I let out on the clutch in 1st gear it locked up the tire. I know I'm in neutral when I try to start it because it has a neutral indicator. And the battery is good I checked it with a multimeter. I'm pretty sure that the starter is still good. I pulled the plugs and they are completely black.

 

Well, if you really want to be sure, put it in neutral, pull all the plugs, pull off the crank shaft end-cover, and try spinning it by hand. You'll have to thread a nice grade-8 bolt into it so you have something to twist it with. I suggest anti-seize on the bolt first, and use a torque wrench. Set it to like 40-50 Nm. If the engine doesn't turn at that point, it's probably FUBR.

 

neutral indicators lie
DMM's lie, only load tests show true battery cell condition
plugs are fouled, bike is running rich for one reason or another... Check out the induction system and then check for the basics. Spark, air, fuel.
