So, the Z250 is nearly gone, and I'm thinking a 2-stroker is the next step. Probably the best transition to a 600 I reckon. Firstly, I'd like to know what 250 2-strokers are around. I only really know of the RG(V)250, and the NSR250. But other than that: 1) How often do they need to be rebuilt (average)? 2) What has to be done for the rebuild? 3) If i'm many k's from home, will it shit itself and need a rebuild, or will it give me fair warning that it's needing the work done? 4)How much does rebuilt cost? I figure a 2-stroker is likely to keep me happy on my weekends. I figure if I can get really get into it and throw 'er around it can put off me wanting a 600 (which I can't really afford, but really want!!!) Thanks guys!
