Hey. Just installed a limited b pipe into my sj. The expansion chamber is only clearing the motor mount by about 3/16. I had to prop the water box up about an inch just to get that. Is that enough clearance. I plan on doing some riding that will jar things around a bit and would prefer not to put a hole in the chamber. Also the chamber was touching the side of the hull, so i stuck a piece of turf between them. hopefully that will do. Thanks for any comments.
