142-199 psi or (1,000-1,400 kPa) is the “normal compression” range.
114 psi or (800 kPa) is the minimum compression required to technically run the motor at all, & anything below that requires servicing.  170 psi or (1,170 kPa) with proper valve clearance is the sweet spot. 
Source: Repair manual, pg. 10, “tune-up specifications”.

Hope this helps someone.

      Has anyone had a suzuki 230 quad lock the engine up?
      By docdoug72
      Has anyone had a suzuki 230 quad lock the engine up?  Its a well maintained bike, it locked up when my son was riding it. Pulled the plug, it has connected with the piston. I'm thinking the con rod let go.  I don't have a service manual.  Does the engine need to come out to check further?

      Where you like to ride and what riding does for you?

      I like to ride in wooded and grassy areas. It takes my mind off the everyday routines and helps me deal with my father's cancer. Also gives me a reason to get involved with forums like this one.

      98 Bayou 220 low compression
      By DZL1
      Question for you guys. I have a 98 bayou 220 that I picked up cheap cause it's wasn't running. So it's has very low compression. It is getting spark and fuel. 
      What should my next course of action be? Any other tests I should perform or where to start looking?
      Thanks in advance.

      1986 TRX 250 Starter Bypass Gear Problems
      By Gwbarm
      I finally got around to working on the TRX, this has been an ongoing problem with this machine. This is a machine that we keep on my Fathers property, i dont see it that often, my brother haad it professionally repaired last year and year before same problem, the new starter gears and bypass gears last about a year and the machine is not used that often, he said he was done with it , so i thought i should go take a look. Sure enough the gears were all malled again. 
       

       

      IMG_4910.mov   There is some slack in there but most is taken up by the gear cover,if anyone with history with these machines has had the same problem, let me know your findings. Where i am now im looking for finding replacement honda gears on Ebay and try those. I suspect the original was replaced with aftermarket gears years ago and they just worse quality as the years go by.
