    I wound up making a smaller air intake hole and kept trimming the hole larger until it wouldn't choke itself out and solved the problem

    heres a short video

    i took both ends off and tapped it on with a piece of wood but you could leave one end on and just drill a new exhaust port in the bottom of the can
  4. goatman started following king quad 300 soup can exhaust
  5. goatman
    bottom of the tail pipe was rusted out and the little nut also ripped off when i tried to undo it. a 540 ml soup can is the same id as the exhaust pipe od and the soup can has ridges to make it a tight fit a little bit of a mickey mouse fix but it works

    it has the right 5d40 jet needle. the jet needle has 5 grooves for the clip its supposed to be in the 4th groove but nothing says groove from top or groove from bottom, tried them all and its at the 2nd from top of carb or 4th groove from bottom. the battery was brand new when i tested the running voltage before so it was sucking some voltage topping up its charge. right now its 14v at motor hot idle and 13.7v under throttle. i think its supposed to have 160 psi compression and its at 110 psi, like i said im just going to be happy with how it is

    the head lights are not hooked up right now, at idle it would show 13.5v and when revved the volts would drop to 13.1v. coil pick up was 120 ohms(100 to 200), the 3 yellow wires 0.6 ohms (0.1 to 1.0). ignition coil primary resistance was 0.5 ohms and secondary was 19,800 ohms (12,000 to 20,000) i was going to have a good look at the jet needle to see if there is a number on it and to move the clip to different positions

    checked stator, coil pick up and coil they all checked out just fine taking off in high it feels like it wants to lift the front tires off the ground its a 1998/27 year old machine, im just going to call it good enough. thanks for your help

    went to 0.006 on the exhaust valve didnt do much of anything except a slight ticking sound
  10. goatman
    a person mentioned to me it sounded like the exhaust valve isnt completely seating. ill increase the exhaust gap a little more tomorrow and see if that helps.
  11. goatman
    yes, i can accelerate through the throttle, before at 1/4 throttle it would bog out so if i wanted to move the quad in high gear it would stall so then i would shift into low to get it to move, now you can see it powers all through the throttle and i can move forward in high gear. ill play with it more tomorrow. when the throttle is pinned it sounds like a rev limiter to me

    Sounds as if the exhaust valve may be slightly off seat.  Adjust it to have more lash and run it a while to see if that improve it.  As it was a "freebie" could it possibly have sat for a while and has had something nest up in the muffler?  IE: Mud Dauber nests, chipmunk:'s forage stores, rat nests, bird, squirrel nests, etc, etc.

      ok, thank you, ill double check the exhaust valve gap again, they say youre supposed to set the gap when the motor is at 30 celsius or about 90F. i think i set it at 0.003, ill shoot for 0.005 tomorrow. is that why it sounds like a rev limiter at full throttle? i had the exhaust and muffler off and nothing was rattling around in there. thanks again

      If you can get your hands on one of those cheap usb inspection endoscopes, you can actually put eyes inside the muffler and pipe.  The dried mud from daubers won't rattle around unless you beat the muffler with a rubber hammer.

      As far as the valve lash, I'd swing big like .009 to .012.  After all, all you are wanting to do is to be sure the valve has ample opportunity to get down on the seat. It WILL be noisy, but you won't be stressing it or letting it bang around for very long.  Just long enough to see if it effects the heating issue with "knowing" raw flame and un burned fuel/air isn't being dumped into the pipes. You can tighten it all up to spec after eliminating possibilities of raw combustion happening downstream of the valve seat and into the pipes.

    this is where the quad got stuck on the van
  14. goatman
    i compression tested it with the carb off 110 psi do they have rev limiters?
  15. goatman
    the foot shifter cable came in from amazon that measured 26.77" and it fits. cam lobes in right direction?, i didnt look at the lobes. i made sure the "A" stamped on the cam was in the same position as it was when i took it out. -A- guess ill find out soon enough

    i cleaned the head gasket up, got all the black compound they use off it and sprayed it well with copper, the head gasket didnt blow, lapped the valves and got all the carbon off them. they spin nice and are not sloppy, timing chain tensioner seems to be working just fine. got it all back together just waiting for the Permatex Ultra Black to set up on the head cover. i wanted to take it up to a mining claim i have this weekend, hopefully this works and ill see if i can do a proper compression test with throttle open
