new pipe and now smoke

[honduh440]

yo i just put the sparks x6 on my bike. ive been running fcr carburator and big gun pipe. I just put on the sparks pipe and now its spittin out white smoke pretty bad but the bike runs great doesnt cut out or anything its a ceramic coated pipe. i havnt rode the bike at all just let it run in the driveway for a few minutes. any ideas why?

white smoke ussualy meens that there is a head gasket leak. Try checking that.

...Is the pipe brand new? If so it is more than likely the coating on the pipe. I have heard of many people say there brand new pipe smoked for a while when they first got it.

Yep.

Put your stock pipe on and see if it still smokes. Process of elimination ;)

[honduh440]

man still smoking i put the old pipe on and its smoked as well i dont see how it could just start burning oil so fast in one day the bike runs perfect doesnt cut out bog or anything. any ideas what it could be? im stumped

[Republicrat]

it could take minutes of lrunning with low oil to smoke a ring. Did you have to put more oil in it? OR it prolly overheated, then piston swelled and scarred or egged your cylinder. It just happened to my 4x4rancher.

condensation in the head pipe ? does it stop smoking after few mins ?

[honduh440]

nope doesnt stop smoking at all i changed the pipe back to the big gun and it does it the exact same. i guess im taking it into N motion soon

Since when did you need a liquid cooled machine to blow a headgasket? :huh

Hey tardzilla, the reason why a blown head gasket causes an engine to smoke is because your burning the liq coolant...
Ablown HG on an air cooled engine wont smoke white:blah: :macho

I heard publix is hiring:devil:

Not the most articulate:huh but correct. Bluish smoke is oil, white is water, black is unburnt fuel. If your still smoking, check you plug is there oil on it? If so do a compression check.

It could be just coinsidence that it started smoking right when you added the pipe, or the motor could have been ready to go and the reduced back pressure from the pipe was all it needed. Either way the pipe was not the cause.

[honduh440]

i pulled the plug out tonight "4 month old plug" and it is drinched with oil halfway up the threads. i dont have a compression tester or really know of anyone who has one. if the compression is lower then it should be what does that mean?

[daimon1054]

If your plug has oil on it then you need a top end job.

well that sux balls..................how bout i just dont put oil in it so it cant burn it anymore

then u can have fun paying for new rockers, valves, cam shaft, valvue guides, and most likely a new transmission. :)


i know for a fact that just the top end w/o a piston and boring will cost right around 650 dollars.

[honduh440]

lol i was just kidding.............well just as im getting ready to sell the bike and start on a 450 this comes along to waste more time BLAH!!!

thanks for your guys help later
