    Slight casting irregularities smoothed out with Dremel, but truly not needed (anal). Kit installed in 3 hours. Slight issue with power valve shaft end from stock 23' 250X and kits power valve shaft end. Just ran out without hold down like earlier YZ250's with no issues. Compression is on another level. Recommend 50/50 mix with race fuel or AVGAS 100%. HUGE power gain in low and midrange. Waiting for weather to be warmer for true ride. If your looking for easy power gains this kit is it!!!
