My 2000 ZRT800, ran great all weekend (I just piped it and cluthed it, and reeds). I use a Digatron EGT gage, and noticed that through the mid-range it ran too lean (1275-1300 I let off), but I noticed ti was alwasy the magneto side goin glean first, is this normal? When I let off they always seemed to equalize right away, but that cylinder alwasy did it first. W/hat could cause this? I plan on dropping the clip one position and chekcing to make sure all the

Not uncomon to have a leaner conndition in one cyclinder, I would RAISE the needles at least 2 on that one and 1 or 2 on the others cyclinders and get the exhaust temp down 100 deg or more.

all 3 of mine ran within 100 degrees of each other after some working,,, I have changed jets, dropped one needle, synched,,,readjusted,,,the works, but now it appears to be fine

Had the same problem on my 02 T-Cat, ran lean on the mag side in the mid range. Raised the needle 1 on the mag side and now they are all within 60 degrees of each other.

I would say it is caused by your pipes. With individual pipes each cylinder is its own separate system and they require their own set-up. The pipes can't be made identical so the jetting may have to be different to compensate.
