Taken the bolts out of the fuel cap but its stuck
The centre of the cap is locked to the tank and needs the key to remove it. you will have to put the bolts back in and try to force the lock with a screwdrivver or drill the lock out. Then remove the bolts to take the cap assy off. The cap needs to be open before you can undo the bolts and remove it.
Can i use unleaded feul in FJ 1200
Im wondering what you have been using up till now?
All alloy headed engines(fj1200) have hardened valve seats and should handle unleaded fuel.
It can help to add a little upper cylnder lube such as moreys.
I would steer clear of any ethanol, E10 type fuels, as they willl damage some rubber carburator components, hoses, o rings, slide diaphrams etc

Changing the old ignition barrel
If the bolts are the allen/hex/torx kind with a dot in the middle, just put a small flat head in there and remove that dot, or go buy some security bits.
If it's any other kind of bolt, use a file and cut a flat groove into the bolt, then either use a chisel and light taps with a hammer, or use a flat head screwdriver to unscrew it.

Second gear slip
1. If second gear is acting like in and out of gear under load the gears are worn needing replacement engine removal and lower end work.
2. If your accelerating and the engine begins to accelerate steadily to a point that your motorcycle is not reacting along with the engine you have a slipping clutch. If this is the problem replace the clutch plates and springs.
No spark at spark plugs so wont fire
Check the coils first, leaving the key on may have burnt out part of your ignition system.
Easiest way to check coils is to pull one lead off, plug a spark plug into it. Run a hot wire from the positive side of the battery to the coil ( Do Not Plug it in!!) . If you flash the wire on and off the power side of the coil it should make a spark jump across the sparkplug ( don't forget to earth the base of the plug.)
If the coils are ok, see if you can borrow a CDI unit to try in your bike ( it is good to have mates with the same brand of bike )
Don't forget to check all fuses first and make sure the "Kill Switch" on the handlebars is on.
Happy fault finding.
Need to know engine sizes and years
Off hand I cannot ID those part #'s, but I know that generally you can call a Yamaha dealer parts dept. and ask the parts manager to help you out. Generally; They will in order to secure your business at a later date.
Good Luck.
None starter,got spark,good battery,fuel,fuses
No starter?
Got a volt/ ohm meter?
Check battery for 12.6 volts or better
check voltage coming to and leaving fuses ( oh yeah you checked all that, I guess you know you have spark cause it will pop start, just no electric starter, right?)
Check voltage at starter ( if 12 volts then replace starter)
check voltage at starter solonoid on battery side if no then check clutch switch, sidestand switch, key switch. If yes then check for 12 volts on starter side when clutch pulled in, key swithc on and starter button depressed. If no then check for voltage to spade on starter solonoid coming from key switch. If yes then replace starter solonoid. If no then check key switch and safety switches.
