I have a 04 proxr800 and I recently had to remove the crankcase plugs to drain some fuel in it(long story).The question I have is that the plugs are brass and seem to have a taper on them.I thought most engines had regular bolts and aluminum washers(or brass washers)in the cases.So I called the dealer and they said there software shows just plugs instead of bolts.They did not know why either.When I put them back in I used locktite and they went in kind of weird.I had a hell of a time trying to get them straight,but once I got them in they only turned maybe 4-5 times before they started getting snug.So my main question is should I have really cranked them down or should I just snuged them(That is what I did).Why did they put these plugs in here instead of bolts?Is this common on any other sleds?The motor has never been tampered with instead of 1 new cylinder and piston(dropped valve common)It has the steel valves and green&yellow springs in now.But they never touched the case plugs.I just have a hard time trusting those plugs in there.Thanks guys!!!!

Those plugs are NPT threads (National Pipe Thread). They have a 3 degree angle so that it will tighten and seal itself. A good snug feeling should be fine as far as tightness. You could probably search on a torque spec for brass NPT's if you wanted to (that is probably an 1/8 or 1/4 NPT). Generally you would use Teflon tape or paste on these plugs but your parable fine with locktite.

ya your always gonna have exopsed threads and 4-5 turns is plenty. so im sure they were put in right. same thread type as any threaded grease fitting on your sled

Why do they use these plugs instead of bolts though?Thanks.

They seal better than a bolt or bolt and washer. Having a vacuum leak in your case would be real bad. Every car, quad or sled engine has them in some form.
