The intake will be made from 6ply wire reinforced silicone rubber but it will have some pliability to squeeze between the shock and frame. I've got a new supplier that I'm working with on this, so bare with me. I bought another R, so I can do some test fitting myself. I just need to go pick it up. I'll be dyno testing this pretty soon. Just about wrapped up with the trx and yfzr, the 250r is my next big project. I plan to have multiple intakes and configurations for the R, including a big drag setup.
