how durable are kz400 motors

its been a long time since i was 5' 7" 130 lbs,i remember i got my first z1 when i was 14 i was about 5'7" and about 110,theres a picture of me in kz1000 gallery from back then! :woohoo: it seems like i spent a lot of time hanging on for dear life with my feet dangling in the breeze behind me trying to catch up with the bike!:whistle: that little 400 should have no problem hauling you down the road

Here is a bit of a different aproach, my brother has been driving his mint 74 XL250 on the highway to work an he found reving too high for his liking. So he replaced the rear sprocket with a 10 tooth smaller an a 1 tooth larger front sprocket. He now finds it cruses on the highway without the high revs an hassent lost any of its drivability.you might not need as a ratical tooth change on the 400, lower rpms = less vibs and easier on the engine Also a good oil change helps,oil now is so much better than it was years ago.
