The Cross over tube helps with mid range performance and helps to smooth power delivery, eliminate flat spots, stumble, bucking, etc. Most of the later Euro/Canadian RD400’s and the RZ350 had this type of intake set up, but was never available in the USA for the RD’s. This kit is a modified verion of the RZ350 intake and requires NO modifications of any kind and is a direct bolt on upgrade for the RD250/350/400 (all years). Rejetting may be required. Kit includes the following:
- OEM Yamaha RZ350 Manifolds x 2 (modified for the RD)
- OEM Yamaha Banshee Cross over tube (metal) x 1
- OEM Yamaha RZ350 Cross over tube clamps x 2
- OEM Yamaha RZ350 Reed Valve gaskets x 2
- Stainless Steel Socket Head Bolt (Allen)/SS washer x 8
