Please help! I have an 82 Yamaha SS440. We just recently rebuilt the motor (new cylinders, pistons and rings) and now we can not get the sled to fire. It acts like it wants to but wont catch and run, just teases ya. I have rebuilt the fuel pump with all new gaskets but that didnt seem to help it. I am at witts end trying to figure it out. Please, any help will be greatly appreciated!

drip a little gas down the cylinders and see if it fires like that if not then it may be an electrical problem if so then ur not getting fuel and should try cleaning the carbs

there could be a hole in the daphram,a problem with your pulse line or if theres water in ur gas it could be frozen gaslines or fuel pump
