The very first time I dumped the oil in my Raptor after I bought it new, there were metal shavings. Should I rebuild? I find some in just about every oil change I do on any past or present quads.
I believe he said he found them in the oil filter. Sounds to me like the filter is doing its job.

Docturbo, if you want to rebuild at the first sign of smoke or metal shavings, knock yourself out. I thank you for your generous donations to our nations economy.

Have a nice day.

 

I agree with this 100%. I would like to add, that the valve guide seals can harden over time, and cause the same smoking. As the engine warms up, the seals become more pliable, and seal better.

 

His warrior sounds exactly like mine. It smokes a little on start up, because the valve seals are starting to get worn. This isn't going to hurt anything at all as long as he keeps an eye on his oil level. I'm pretty damn sure that his metal shavings are coming from his failing starter clutch, because I experienced the same problem he is having and the shavings were mostly gone the last time I checked the filter. If anything goes wrong with his engine it's going to be because those metal shavings got into bearings and tore everything up. A rebuild isn't going to do any good when his metal shavings are coming from the starter clutch.

 

the several times ive rebuild motors ive never put new valves in them. so most likley the guy that rebuild my motor never either, so im not worried about the valves as i know the problem. but that starter clutch and metal shaving are what get my attention, what exactly happened when the starter clutch went out? did the one way teeth wear out? did it hurt anything else? cause i dont want to tear into the engine to find out nothin needs worked on.

 

my warrior makes the clank starting up and turning off but i have never seen more than maybe lile 5 metal flakes

 

maddmudder13, recon99 is giving you good advice. Check out the one way and see if that is where the metal is coming from. If so, you can buy a new one, flush the engine of metal and be on the trails again in no time.

One thing that REALLY concerns me is when you talk about the plug gap closing up. Only one thing would cause that. There is something loose in the combustion chamber, or something broke and caused contact. That is not good news any way you cut it.
Sorry I don't have better news for you, but plugs don't close up by themselves.
I would do a compression when you pull the plug to look at it today.

 

the only thing i can think of for the plug cap closing is that the rod bearing are a little long and when i revved it up that far the piston barley nicked the spark plug. sence i was at such high rpm, but it is still running good
