hello riders

Picked the atv up not running. owner did know not why it wouldn't start.(kinda fishy) tore it all down. previous owner put brand new piston in it and gasket set. No marks on the piston so it wasn't running after he rebuilt top end. someone been in it. LOL. checked rings. all ok. Valves are seated.timing dead on.

put it all back together.

Well the 2002 honda 400ex still won't start. Went through everything again.

The spring and plunger for the decompression cam is missing. Will this make it not start. Has the stock cam in it.

What do you guys and gals think????

      1996 Yamaha Timberwolf 4x4 Rear End Width
      By McG75
      1996 4x4 Timberwolf rearend width. Can someone with some knowledge of these machines answer this question for me please. Are all 4x4 timberwolves this narrow in the rearend? These tires are so close the right one actually rubs the muffler.  Thinking about seeing if there are any spacers out there for it. I need at least an inch more clearance.

      In search of the backwoods nudist campsites and ready to select the right ATV.
      By mehim
      Hi everyone. 
      Let me explain the thread title. 
      My husband and I are very active in the nudist community, and we have stayed at many and most of the mainstream nudist and clothing optional campgrounds in the USA. We are now approaching our retirement and would like to start a podcast to share those off the road / backwoods / little known camping areas where nudity is allowed. We have purchased a 5th wheel camping trailer with a rear garage for the ATV and now need some good reports on the one to buy. 
      We are most interested in a side by side unit but would love to get your thoughts. 
      Feel free to stop by and say Hi and ask anything you would like to better understand what we are looking for in an offroad unit. 
      Thanks for reading and hope to hear from you.

      Looking to buy a new SUV
      By Gwbarm
      I have been exploring all the options available, so many, its hard to choose. I have kind of narrowed it down to the Honda Pilot, Subaru Outback, and Kind of looking at the Outlander, although its a little small,  the new one is nice looking. Just wondering if anyone has any recommendations or gripes with any of these rides. I have driven Jeeps for the past 25  years and they have been great, but their price point has gotten to high. Expieriences good or bad would be helpful. Thanks!
