I too have a 250x, Is the 350x carb a powermod for significant increase in juice or no? the 91-92 250x's have red frames. and I would say that 100.00 for a 250x needing a bit fo work is an awesome find. Got mine for 400.00, got royally screwed by an engine shop for over a grand on a rebuild, ended up with a running engine, bore to a 390, leaks oil like a seive, and they not only forgot some very important bolts, but failed to install the orings with the gasket, failed to locktight the rod bolts, AND stripped out 7 of the valve cover bolts. great shop to do business with. I'd use them again (for target practice anyways...)
