Help with a 1992 XJ600

[ssterry]

I pulled my 1992 Seca 2 out of storage last march and it ran perfect. I got really busy and didnt get to play with it for 5 weeks and now it will fire right up and while its warming up each cyindler will eventually cut out and will not start after for a while. Iv tried a fresh tank of gas and the spark plugs and air filter are clean. The same thing happened last year and through 2 months of frustration i found that the Canadian model spark plugs were installed so i installed the ones listed in the shop manual and it ran great until i whimped out and put the bike away in November.
Any ideas?
