i have a 99 400 ex with a big bore kit. I bought a new stage 2 hot cam for it and got the timing right. it cranks over but won't start. Looking at it today a little more...i think i have a bent valve. I pit the compression tool on it and only have 25ftpnds. not sure how to fix that. Nor do i have the tools. Also, i noticed that there are double springs on it too.is that normal?

A bent valve will definately cause that problem. If it is not sealing you won't get compression. As far as how to fix it I am sure Oxidized_Black has a pdf link for the manual listed and you can see what it will involve from there. Good luck and keep us posted with progress.

      2000 Yamaha big bear 400 won’t start
      By Mister907
      Hi guys, I have a 2004 big bear 400. Last winter while plowing the driveway, I heard a loud pop from the left side of the engine. It continued to run as I looked for leaky fluid, but then died shortly after backing it up and won’t start now. The oil light comes on when I try to start it, no noise or anything else. 
      No blown fuses that I can find.

      Anyone have a Suzuki LT185 owner manual?
      By rjsummer
      I just bought a 1984 Suzuki LT185 ATV and am looking for the OWNER’S manual. ( not a service manual) 
      I contacted Suzuki Canada but they have no paper or digital copies in their archives. 
      Does anyone possibly have a digital copy they’d be willing to share?
