i have a yamaha phazer that i purchased and am in the process of getting it back runing i am having troubel figuring out why i'm only firing on one cylinder i'm getting spark fuel and compression i cleaned the carburators and even try'd pouring alittle gas into the cylinder but still nothing except it sometimes kicks in at higher speeds any suggestions ?

I've had the same problem with my previous sled...when I tok off the Y pipe I saw that a skirt was broken on the exhaust side...I had good compression but the only thing I've noticed is that it took maybe a half pull more to get the same compression than in the good cylinder...It only ran on one cylinder but when I'd pinned it the one with the damage piston was fireing up

look at the pistons like xcr 800 said. the also look at the carbs that they are moving the same. not that one is a half inch higher than the other.
