350x timing

[jcraig]

i pulled the 350 out of the back of my truck. ell i guess the front wheel hit pretty hard because the timing is off again. it ran great the night before. anyone know what i should i be looking to replace or check.

I've never heard of timing going off due to a hard jolt. I drop my x straight out of my truck all the time and don't think twice about it. That just doesn't make sense. You mentioned "the timing is off again". Has this happened before due to a hard jolt? This is weird stuff. Does your top end make a lot of noise when it's running?

[jcraig]

no weird noise. i bought the trike, couldn't get it to start. so we cheked the timing and it was off. fixed it at work, rode it for about ten minutes and loaded it up in the truck. next morning when i got home, pulled the beast out of the truck and wouldn't start. pulled head cover and found timing off again. crazy?

im gonna say you timing chain is stretch bad or the tensioner is no good inspect the sprockets for the chain as well

on leave all week gimme a call.

If that chain is stretched so bad or has a tensioner that fails and allows it to jump time from a drop out of a truck, it could not even run. I'm thinking more, loose flywheel or sheered key. There is no way it's gonna jump teeth on it's on without self destructing.....

how can i tell if the tensioner is wore out? if i got the bit bore kit, should i find a different cam sprocket smaller or bigger?

[Dirtcrasher]

Big Bore?? I'd try and find out what exactly is wrong with your motor as it is first.

Larger pistons don't change the timing at all. The stock cam sprockets remain the same. The cam turns twice for every crank revolution.

You really need a manual..... Remove the 2 bolts that hold the tensioner on and take it off. It is spring loaded so to speak and keeps tension on the chain without need for adjustment.
