thanks for replying.  your the only one i guess.  what should the compression be?   check compression?is there a compression release to close before i  check?  ill take some pictures tomorrow but all the plastics are off while i'm working on it.  i was told it was a kit build from 2014.  it has genuine Suzuki parts though, so it looks like i got a pretty new lt500 and suzuki is still making this quad under a doityourself kit..  it looked brand new when i bought it.  it wouldn't start though, so i tore into it.  the guy had hacked in kill switch with **** nest of redundant wiring.  i guess to confuse a thief? fixed it, ran it, blew/ripped exhaust hole in racing exhaust system improperly installed. welded it kinda crappy, then tossed  a chain.  replaced both sprockets and chain. bent rear rotor unloading/dropping it. awaiting new rotor and finish adjusting chain tension and alignment and it should be ready to go again.  starts right up but  needs to warm up before performance is good.   then it will tear you new ass.  my arms/hands hurt from holding on.
