just got my 02 750 gixxer fixed but still leaking antifreeze. I changed the waterpump o ring but looks to be coming from where the waterpump inserts into the block. is there anyway to seal it up any better. the reason i got it fixed is because the chain flew off and busted the waterpump off, along with the bracket that holds it so i had a profesional welder weld the bracket back on and im not sure if it is now sealing right. so thats why im wondering if he didnt weld it to specs and if i can do something to make it seal better. i appreciate any info. thanks.

You're talking about a catastrophic incident. Repairs of this nature are very difficult, and it's not likely the welder did it successfully unless he is exceptionally talented and experienced.

When you say you're "wondering if he didnt weld it to specs," to what "specs" would you be referring? I don't recall anything in the service manual that specs weld repair.

Sorry I can't offer more help. Repairs of this nature are sketchy and difficult. It's possible that the hole the o-ring is supposed to seal is out of round from heat distortion. A dab of silicone around the o-ring hole might help, just don't be too generous with it.
