The Zephyr Zone

I bought my 400 with a GPZ 550 engine already fitted. Not sure what gpz model it is but anyway I got a set of zx600 carbs for it, a straight through homemade exhaust system and pod filters. I just happened to have a set of longer needles with different clip positions if needed that came out of zeph ...

Wire wheels on the 750 are both 17 inch and the rear at least is narrower than the 1100. The 1100 has an 18 inch up front.
