hi,
i removed my plugs in november cause my bike (an old `82 yamaha XJ 550) was going to be sitting for a while. yesterday i started to get things ready to ride again and went tried to screw in the plugs and the outer plug on each side won't go. i fiddled with each thinking i just wasn't threading them right but no dice. somethings ups with the cylinders i think.
any ideas on whats wrong? i replaced the plugs a couple months before removing for the winter and had no troubles ...
thanks - nathan

Have the threads on the bike or on the plugs rusted or corroded?
Did a mouse crawl inside through the spark plug hole?
Not sure why you removed the plugs in the first place. If you wanted to winterize it, spray some fogging oil into the cylinders.....

TURN THEM OVER!
ps: I had a neighbor who did just that. Tried to put them in upside down.

Wow, what the heck kinda temp difference are you working in??
Hopefully the threads are not cross threaded, either on the bike or the plug. If the plugs are not new, maybe give a new set a shot and see if they'll install. I know, not the real technical solution, but plugs aren't too bad that it won't harm to throw money at
Edit: are you sure you put the plug in the same cylinder it came out of?

Another tip is to use anti-seize on the plug threads.
At $2 each, new plugs are a cheap fix to many problems.
I just hope the threads on the bike aren't corroded.
