Just wondering about the timing setting on my new sled, a 97 xc440 with the fuji twin not the domestic twin. I know that its the same engine as the 96 xcr 440, but i was reading on a different site that the 96' spec engine has a different timing setting, and that the 97 xc 440 engine had the timing slightly retarted in an effort to "detune" it for trailability. I'm not interested in trailability[!]. I'm interested in power. If anyone knows what the factory timing spec is on a 96 xcr 440, i'd love to find out. I've also never adjusted the timing on a 2stroke so any info on how to actually perform it would be awesome.
