K157FMI (LexMoto Lowride) intake manifold

Hi all, been having some issues with my bike, which ive now traced to a hole which has appeared on the intake manifold, over the space of 2 days it has gone from a hole to a gaping crack.

The bikes less then 2 weeks old, and under warranty so ill be taking it to the dealers to get rectified, but there going to be putting a replacement manifold of the same type on it, which is this one:


Attachment 8833


Does anybody know a good alternative manifold that will fit?

Thanks

It's for Keihin PZ26 alike slide carb. Most Suzi is using Mikuni CV carb.

This one looks perfect http://item.taobao.com/item.htm?id=17164827552 if only it had the sai valve on it :(

Is the SAI essential or can it be left of?

you can plumb it. its not necessary, its just for euro emission, second thing is crank breather, that should be kept, to keep your oil cleaner.
