Need some shock suggestions for a 150cc custom setup, also intake manifold question
 

I'm running an open wheel setup with a single shock on the left side. Have any of you guys managed a linked shock setup working around a GY6? I have a very nice R6 shock I want to use if I can, but managing a link from the case's rear like it is from the factory is proving problematic. I'm just wondering if anyone here has manage to pull it off.

Secondly, this engine came with a rear facing intake manifold. I want it to point toward the front. I can make a new manifold but it would be nice if someone made one I could just buy. Anyone know of such a thing?

I'll put up a pic of my chassis here in a bit for a little more detail.

Ive had to turn intake maifolds foreward for big carb builds, only issue i found was the plastics hitting the carb or air filter, dremel time
