today i fired up my 350x cold. it smoked first time!!!! alittle then i revved it alittle and it stoppped i turned it back off for 15 min and back on and didnt smoke, i checked my compression it has lots of compression left still, what is causing this? is because of age? damn this scares me. i dont want to look stupid riding my X with blue smoke comming out when its a four stroke. can anyone help me of whats causing this?

 

is it a lot of smoke? my 200x used to smoke a little on a cold start.

i dont know if its due to age on the oil rings and small amounts of oil getting by the rings before things get a chance to heat up and expand or what.

 

yea kinda just on cold start ill got check right now if it smokes again.

 

i checked it, started fine revved it up no blue smoke, thats wierd. and has lots lots of compression on that stock piston, and has fresh oil. motor runs like new.

 

Your valve seals could be bad or it could be just a lil extra gas that when you started it flooded it for a sec. Flooding I think is black gas and oil smoke is blue. I think[img]i/expressions/face-icon-small-wink.gif[/img]

 

well the bike starts up on first or 2nd kick and blue smoke comes out. at cold start so its oil burning what can i do to stop that.

 

A small puff of smoke is nothing to ruin a good pair of pants over. Just keep your eye on it, and note if it gets any worse. For now, just roll with it.

 

Yeah, dont worry bout it, it doesnt sound that bad yet, but like Glenn said, if it gets worse, look into it further.

 

yesterday i took the trike for a ride, smoked alittle at cold start rode it for like 2 hours(on my log book) then cam back let it rest, then this morning i go over there and its very cold outside crank it up cold starts at 3rd kick no smoke just black smoke of the choke on. so thats wierd what could that been.

 

Sounds like valve seals to me. I wouldnt worry about it to much. If it is making you worry a whole lot then save up a few $$$ and order you some new top-end parts for like a piston, valves seals, guides, keepers, and springs. thats would surley get rid of any problem that you are having
