I'm considering one of Eric's overbore kits for my 98 KX250. Looking for recommendations between the 310 and 265 (2mm over). Quite honestly, I'm satisfied with the current power of my 250. To this end, I'm aiming towards the 265 in the pure interest of plating repair. But should I consider the 310? Sounds like it'd be a handful for MX but don't know for sure. Would appreciate any feedback on the pros and cons of these two options.
