check to see if driveshaft to rear is turning.if it is, either the ring gear & pinion gear in the differential are not making good contact either from being worn, or out of alignment due to worn bearings in differential case,or both.check if axle has back & forth play in differential,indicating worn beaings. also could be worn ring gear to axle contact in differential.check for vibration in axle while in gear increasing as you give it more gas, caused from ring gear teeth slipping past teeth on axle.they would have to be replaced together. oversize wheels & tires tend to accelerate axle/ring gear contact teeth.

Does the bike have a sidestand switch that cuts the power if the stand is left down? If it does, disconnect it and temporarily join the ends together and try starting....

Sounds like a slightly bent shift fork. The slider gear isn't quite engaging into 2nd. If the bend gets worse then you won't get into first and the pedal will get real stiff in those gears. The repair is best done in the shop.
Please rate this solution. Thanks!

You have a bent shift fork. The repair means taking the engine out of the frame then removing the top end, removing the flywheel and electrics, removing the clutch , shift mechanism and kick starter and a few other parts. THEN you are ready to split the gearbox to remove the gears and crankshaft and then the shift drum and bent shift fork. Next you get to put it all back together. This is a pretty big job for the home mechanic.
You will need an impact driver, flywheel puller, case splitter and torque wrench plus the normal screwdriver, pliers, etc.. Alternate to the special tools is taking it to the dealer and say "Fix it".
I normally tell people to take it to the shop just so they don't get into such an involved project.

SOURCE: Yamaha FZ 400 engine timing
hi,normal way to set up fz is as follows,remove left hand engine cover and you will find cdi picups with a backing plate and interrupter tongue,remove all the spark plugs(dont get the leads mixed up),turn the motor by hand up to top dead centre on no1 piston,the tdc mark the plate will line up with the cdi pickup,no1 piston will now be at tdc,both sets of valves ex and intake should be closed and the tappets slightly rocking,if thay are not and any of the valves on no1 piston are open or tight,look to the end of the camshaft (where the cam fits into the bearing surface)and there will be a horizontal mark on each camshaft,release the cam chain tensioner,slip the camchain off the sprockets and rotate the camshaft untill the marks on the camshaft are exactly parrellel to the rocker box mating surface,fefit the cam chain and check alignment then retension the adjuster and check the marks again,if you have it right the marks should still be exactly parellel with the rocker box and the piston should still be sitting at tdc,if it is out by 1 tooth do it again untill it all three marks are exactly right,failing to do this WILL result in a valve sailing through the top of a piston,then it becomes a bigger job again,after you have got them adjusted correctly ,turn the motor over by hand to check that nothing is binding,if you are satisfied that everything is right,then use the starter and you should have compression,hope this helps
