XLXR 25th December 2007, 14:26 If you insist on staying with the 418's, I would go with 13.5" and 90/130 spring, especially if you plan on doing any significant 2 up. 220 is probably the max weight the 90/130 spring can still get a decent ride solo. http://www.thekats.com/vroc/rvw-008.html recipes using jumbo shells
