    I found it easier to put the piston in the cylinder before putting the wrist pin in. Less screwing around i think.

      I have buddies that are harley guys and they all put the piston in the jug just to the bottom of the oil ring land, seems to make assembly a lot smoother and less time that the flywheel is exposed.

      I found it fairly easy to do just make sure and count your links

  • @draggerlane04090
    @draggerlane04090 Před 4 lety

    So you rebuilt this with 94mm bore and left the top end stock. Wouldn't that choke the motor? I would go with kibblewhite diamond valves, kibblewhite diamond spring kit, with a stage 2 hotcams, Keihin FCR Carburetor. And for the exhaust I would do a full aftermarket replacement like a Big gun or Yoshimura RS-2 Series Slip on muffler with a FMF Powerbomb header. Then that upgrade will be complete. My experience you can't just change the jug and piston and expect performance gains.

    Heyyy i have a question (might be stupid question) my exhaust cam was causing a ticking noise on my LTZ 400 i figures since im going in the engine and replacing it id doo a top end, does my cylinder have too be Rehoned ? Or am i aloud too just throw a new OEM piston in there with fresh rings

    • @ChadMyers73
      @ChadMyers73  Před 3 lety +1

      I would say it probably depends on how much where are scarring is in the cylinder

      @@ChadMyers73 I come from the world of motorbikes where a piston is changed about every 60 hours, but with an LTZ I would use it in the countryside and in the woods, so I wanted to know if it is necessary to change the piston every few hours, and if so how often?

    • @ChadMyers73

      Just like all other 4 strokes they need changed about 50 to 75 hours. With 2 strokes being about 25 hours

    Dude, as far as the weather it's not much better down south. I'm north bound in the Mississippi River and as soon as I came through I-10 bridge it was like someone flipped a switch. From heavy fog to 35 mph winds and holding. Mother nature is angry.

    I have a Z400 that was parked about 4 years ago I drained all the gas and clean the carburetor could not get it to start I put a compression gauge on it and it is reading 0 I don't see how it could have blown up not running any ideas?

    • @ChadMyers73
      @ChadMyers73  Před 4 lety +1

      Did you put oil in the cylinder and do a compression test that way also. If you do that and you then have compression then the rings are rusted and stuck. You'll just have to re-ring it. Hope this helps and thanks for watching!

      Dan Matz Yes it is possible. Put a tablespoon of oil in the cylinder and recheck if still no compression than there is a valve issue.
