If it's liquid cooled then that grey smoke is more than likely steam ( the head gasket is on it's way out). If it was burning oil you would able to smell it.,,

What is wrong here ?


my thoughts are its sucking in trans oil from a bad main seal on the primary side.Other possibilties are you over oiled your airfilter or you are putting in to much oil in your mix .

How do i lower the throttle pin on 2001 ktm 300 exc


if you need you bike jetted for 7000, take it to a shop and have it jetted.
If you dont understand your carburetor and make the wrong adjustment you can lean out and blow up the engine.
when you jet a bike for 7000, you need to change everything, main jet, idle jet, idle mixture, idle, and needle position.

What is the fuel mixture for a 2002 KTM 300 EXC 2 stroke? Thanks


WIth Shell v-power and your favourite 2-stroke oil, you could go 50:1 (that's from my dealer). I have been running 50:1 since my 2002 300 EXC has been new, always use new mix for every ride, and drain whatever leftover is in the tank every two weeks.

1999 Toyota Camry grey smoke from exhaust


If it is grey smoke it sounds like steam which sounds like the cylnder head gasket is bust and needs replaced - if it has overheated then the worse case sceanrio is that the cylnder head may need reground or replaced. If the "smoke" is black then its burnuing oil and the seals are bust - much bigger job and more $'s.

My ktm 450 exc 2005 burns oil and makes blue smoke and I have got oil in airbox but i dont know why it is burning oil. What could it be. Please help


this is usually because of a few things,,,check,,,, and maybe change your plug,,,check gap,,,,adjust your carb,... it sounds like it is way to rich,,,,,lean it out a little,,,,,,and the worse problem,,,,,your rings on the piston may be getting worn,,,,and allowing oil to seep by,,,thus,,going into your airbox,,,,,,and combustion chamber,,,,, then blue smoke,,,,, take a compression check if all else fails,,,,,,, this will tell you if your rings are bad,,,,,, JOEL

After 1,5 ours, no oil left in engine looking in glass


If engine is cold, fill oil again to oil level and letit idle for about 5-15 minutes.. See if any white-blueish smoke comes out from exhaust when started or anything leaking anywhere. If any leaking, post your observation. Cheers.
